INSTALLATION

• The pump must be installed and serviced by a suitably qualified person to avoid hazards. Incorrectly installed or tested equipment may fail, causing severe injury or property damage.
• These instructions are a guide only. Should you the installer or owner of the product be unfamiliar with the correct installation or operation of this product you should contact a suitably qualified person for advice.
• Do not connect the system to a high-pressure or mains water system.
• This pump is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the pump.
• The WhisperFlo VS 1500 is electrically connected. Ensure that it is isolated from the electrical supply during installation and any subsequent service work.

1. Plan the position of the pump
   • For best performance, allow pump suction inlet height to be as far below water level as possible and allow the use of a short, direct suction pipe with minimum bends (to reduce friction losses).
   • a. Have enough ventilation to keep the ambient temperature below the motor’s rated ambient temperature whenever the pump is running.
   • If installed in an enclosure/pump house, the enclosure must have adequate ventilation (200sq.cm min, inlet & outlet) and air circulation. Allow 200mm to keep the rear of the motor clear.
   • b. Have adequate floor drainage to prevent flooding and be protected from excess moisture.
   • c. Be solid, level, rigid, and vibration-free.
   • d. To reduce vibration and pipe stress, bolt pump to mount. Fixing holes accept 12mm fasteners.
   • e. Be within 2m of a power outlet for electrical connection (refer to AS/NZS 3000 for rules regarding the connection of electrical equipment in pool zones).
   • f. Allow adequate access for servicing pump and piping.
2. Piping
   • For best performance, allow pump suction inlet height to be as far below water level as possible and allow the use of a short, direct suction pipe with minimum bends (to reduce friction losses).
   • a. Use only Australian Standard PVC pressure pipe. For best performance use at least 50mm diameter pipe for all connections to the pump.
   • Never use a suction pipe smaller than pump suction connections (50mm) and use a larger pipe for long suction distances.
   • b. To avoid stress on the pump, support both suction and discharge pipes independently. Place these supports as close to the pump as possible.
   • c. To avoid a strain left by a gap at the last connection, start all piping at the pump and run pipe away from the pump.
3. Pool Outlets
   • a. The pump suction system must protect against the hazard of suction entrapment or hair entrapment/entanglement. The pool outlet piping must be under the latest AS1926.3 standard.
   • b. Suction outlet covers and skimmers must have been tested and found to comply with the latest AS1926.3 standard or ASME/ANSI specification for Suction Fittings.
4. Electrical
   • Do not use extension leads as they are unsafe in and around the Pool Zone.
   • Hazardous voltage. Can shock, burn or cause death.
   • To avoid dangerous or fatal electrical shock, turn OFF the power to the pump and remove the plug from the outlet before working on electrical connections.
   • a. Electrical installation shall be under the national wiring rules (AS/NZS 3000) taking into account its ratings (Class I, IPX6). The pump is supplied with a standard Australian 10 amp plug and 2 meters of cord. Select the correct Pool Zone for installation.
   • b. An RCD with the maximum rated residual current of 30mA is required for the power supply to the pump. Additionally, if a suitable socket outlet is not available a weatherproof socket must be installed by an electrician in a suitable location. RCD tripping indicates an electrical problem. If RCD trips and will not reset have a qualified electrician inspect and repair the electrical system.
   • c. Incorrect voltage can cause fire or seriously damage the pump and void warranty.
   • d. Voltage at the pump must not be more than 6% above or 10% below motor nameplate rated voltage or the pump may overheat, causing overload tripping and reduced component life. If the voltage is less than 90% or more than 106% of the rated voltage when the pump is running at full load, consult the power company.
5. Equipotential bonding
   • If equipotential bonding is required, connect all metal parts of the swimming pool or spa structure and to all electrical equipment, metal conduit, and metal piping under the wiring rules. Run a wire from the equipotential bonding terminal on the pump (bottom, left motor bolt with serrated washer) to the pool bonding structure.
   • The bonding lug should be used to bond the motor frame to the equipment pad.

OPERATION

• NEVER run the pump dry. Running the pump dry may damage seals, causing leakage and flooding. Fill the pump with water before starting the motor.
• Freezing conditions will damage the unit, as water expands as it freezes. Ensure that the WhisperFlo VS 1500 is located so that it is not prone to freezing, or ensure that the product is disconnected and dried of water during cold conditions.
• Trapped air in the system can cause an explosion. Ensure all air is out of the system before operating or testing equipment.
• Fire and burn hazards. Modern motors run at high temperatures. To reduce the risk of fire, do not allow leaves, debris, or foreign matter to collect around the pump motor.
• To avoid burns when handling the motor, let it cool for at least 20 minutes before trying to work on it.
• Small children using the pool must ALWAYS have close adult supervision.
• Pump suction is hazardous and can trap and drown or disembowel bathers. Do not use or operate the pump, pool/spas if a suction outlet cover is missing, broken, or loose.
• Follow the guidelines below for a pump installation that minimizes risk to users of pools and spas.
• NEVER tighten or loosen the trap lid while the pump is operating.

Priming the pump

• It is not necessary to lubricate the oring. The original equipment O-ring contains a permanent internal lubricant.
• a. Before removing the trap lid, SWITCH OFF the POWER SUPPLY to the pump.
• b. CLOSE SHUT-OFF VALVES on suction and discharge pipes, if present.
• c. Remove the trap lid (turn anti-clockwise).
• d. Fill the trap tank with water.
• e. Check the lid o-ring and sealing surface, ensure there is no dust or debris on either, and replace the lid (turn clockwise to tighten by hand only – no wrenches!).
• f. Open the shut-off valves on the suction and discharge pipes, if present.
• g. Release all air from the filter, pump, and piping system (refer to filter owner’s manual). In a flooded suction system (water source higher than the pump), the pump will prime itself when suction and discharge valves are opened and the air is released.
• h. Switch the power to the pump to start.
• i. Pump should start to prime now. Priming time will depend on the vertical height of the suction lift and the horizontal length of the suction piping but is generally between 30 seconds to 3 minutes under normal installation conditions.
• j. The WhisperFlo VS 1500 will start slowly but ramp up to 3150RPM for the first 3 minutes to assist priming. It will then switch to the selected speed (Step 1).

Control Panel Overview

• CAUTION If power is connected to the WhisperFlo VS 1500 Variable Speed Pump motor, pressing any of the following buttons referred to in this section could result in the motor starting.
• Failure to recognize this could result in personal injury or damage to equipment.

2. External Control Only LED Indicator – Indicates that the pump is operating in External Control Only mode. When the LED is illuminated the schedule is disabled and the only input is from the low-voltage external controls.
3. Start/Stop Button – Used to Start and Stop the pump. When the pump is stopped and the LED is not illuminated, the pump is unable to run from any type of input.
4. Display Mode LED Indicators – An illuminated LED indicates the information being displayed on the screen at any specific point. A flashing LED indicates that the parameter is currently being edited.
5. Display Button – Used to toggle between the different available display modes. This button is also used to set the 24-hour clock and screen resolution.
6. Quick Clean Button – Used to run a selected speed and duration programmed for Quick Clean. When the LED is illuminated the Quick Clean schedule is active.
7. Power LED Indicator – An illuminated LED indicates that there is live power being supplied to the pump.
8. “+” and “-” Arrows – Used to make on-screen adjustments to the pump settings. The “+” arrow increases the value of a given setting, while “-” decreases the value of a given setting. Pressing and holding down either arrow button will increase or decrease the incremental changes faster.

Activating/Deactivating the Time Clock

• When the pump is first plugged in, the clock will not be turned on. This means the pump will start from speed 1, whenever the pump is powered up.
• The pump will then proceed to speed 2 after the programmed duration for speed 1 has elapsed, and so on for speed 3. This is the recommended setting for when the pump is connected to a salt chlorinator.
• If the pump is running as a standalone device, then it is recommended to activate the time clock.

To activate the time clock:

1. Press and hold the Display button for 3 seconds.
2. Cloc” will be displayed on the screen.
3. Use the “+” and “-” arrows to choose between the time clock On or Off.
4. Press Display to advance.
5. Use the “+” and “-” arrows to adjust the screen’s backlight brightness.
6. Press Display to exit the Setup menu. Automatically set itself to the Speed 1 start time, blink, and advance. The pump will also run the associated schedule from that start time.

Setting the Clock

When the pump is first plugged in, the clock has not been set. Any daily schedule set by the user will be based on this clock setting, so it will be necessary to set the clock first.

To Set the Clock:

1. Press and hold the Display button for 3 seconds.
2. Use the “+” and “-” arrows to choose between a 12 or 24 hour time format.
3. Press Display to advance in the Clock Setup menu.

5. Press Display to advance.
6. Use the “+” and “-” arrows to adjust the screen backlight brightness.
7. Press Display to exit the Clock Setup menu. The clock is now set.

• During a power outage, the drive will retain the clock setting in memory for as long as 24 hours. If the power is out longer than 24 hours the clock will have to be set again.
• If the drive has lost the user-set time, the clock will continuously blink until the time is reset. Once the time is reset the clock will stop blinking.
• Note: When power is returned to the pump after a prolonged outage (24+ hours) the clock will automatically set itself to the Speed 1 start time, blink and advance.
• The pump will also run the associated schedule from that start time.

Using the Default Schedule

The default schedule is designed to provide enough daily turnover to service a typical pool. See Table 1 for the default schedule.

	DURATION (Hours)	SPEED (RPM)
SPEED 1	2	3000
SPEED 2	10	1400
SPEED 3	2	2200

Table 1: Default Schedule

• SPEED 1 is set to begin at 8:00 am and run at 3000 RPM for 2 hours. When SPEED 1 is complete the pump immediately begins running the default SPEED 2. SPEED 2 is factory default to 1400 RPM and will last for 10 hours.
• When SPEED 2 has completed its run the pump will run SPEED 3 at 2200 RPM for two hours.
• After 14 hours of run time and completing its run of SPEED 3, the pump will enter a stationary/paused state for the next 10 hours. The pump will restart at 8:00 am the next morning and cycle through the default schedule again.
• The pump will continue to run in this manner until a custom schedule is programmed into the drive by the user.
• Note: The Start/Stop button must be pressed, and the LED lit, for the pump to run. If the time clock is turned off. The pump will start at speed 1 whenever the pump is powered up.

Custom Schedules

• To customize the run schedule for your WhisperFlo VS 1500 Variable Speed Pump, the pump must be stopped. Be sure that the Start/Stop button LED is not illuminated.

Programming a Custom Schedule:

• Note: When programming, the LED light next to the parameter (“Speed”, “Time” and “Duration”) you are setting will blink.

1. Stop the pump if it is running by pressing the Start/Stop button.
2. Press the “1” button. The LED above the selected SPEED will begin to blink and the “Speed” parameter LED will blink while editing. See Figure 3.
3. Use the “+” and “-” arrows to adjust the speed in RPM for SPEED 1.
   • Note: Speed is adjusted up or down by increments of 10 RPM.
4. Press the “1” button again and the display will change to SPEED 1 start time. The “Time” parameter LED will begin to blink. See Figure 4.
5. Use the “+” and “-” arrows to adjust the daily start time for SPEED 1. If the time clock is turned off, the start time is not selectable on speed 1 and the menu will go straight to the duration setting.
6. Press the “1” button again and the display will change to SPEED 1 duration. The “Duration” parameter LED will begin to blink. See Figure 5.
7. Use the “+” and “-” arrows to adjust the duration for SPEED 1 in hours and minutes.
   • Note: The duration parameter is adjusted in 15-minute increments.
8. Pressing the “1” button will continue to cycle through these parameters, but the changes are immediately saved as they are adjusted.
9. Press the “2” button. The LED above SPEED 2 will begin to flash and the corresponding parameter LED will flash while editing.
10. Use the “+” and “-” arrows to adjust the speed in RPM for SPEED 2.
11. Press the “2” button again and the display will change to SPEED 2 duration.
    Note: SPEEDs 2 and 3 do not have a start time, as they begin their duration immediately after the previous SPEED finishes.
12. Use the “+” and “-” arrows to adjust the duration for SPEED 2 in hours and minutes.
13. Repeat steps 9-12 to program SPEED 3 and QUICK CLEAN.
    • Note: Remember that the duration allowed for SPEED 3 will be limited to the remaining time in a 24-hour day.
    • Any time in the 24-hour day not programmed into SPEEDs 1-3, the pump will remain in a stationary state. [ SPEED 1 + SPEED 2 + SPEED 3 < 24 Hours ].
14. Press the Start/Stop button and ensure the LED is lit. The pump is now on and will run the custom user-programmed schedule.
    • Note: If the pump has been stopped via the Start/ Stop button, the pump will not run until the pump is turned back on by the Start/Stop button. If the Start/Stop LED is illuminated then the pump is on and will run the programmed schedule.
    • Note: If a user wants to have a time during the day when the pump is not running, any of the SPEEDs can be programmed to 0 RPM. This will cause the pump to remain stationary/paused throughout that SPEED.

Speed Priorities (Non-External Control)

• For schedule duration settings, SPEEDs are prioritized as follows: SPEED 1 -> SPEED 2 -> SPEED 3. SPEED 1 is the highest priority, while SPEED 3 is the lowest.
• The drive will not allow a user to program a schedule of more than 24 hours. When the 24th hour of duration is programmed it will take time from the lower priority speeds to add them to the SPEED currently being adjusted.

Example: Starting Schedule (Before Adjustment)

• SPEED 1 duration = 20 hours
• SPEED 2 duration = 2 hours
• SPEED 3 duration = 2 hours
• If the user reprograms SPEED 1 to run for 23 hours, SPEED 2 (lower priority speed) will automatically adjust to a 1-hour duration and SPEED 3 (lowest priority speed) will adjust to a 0-hour duration.

End Schedule (After Adjustment)

• SPEED 1 duration = 23 hours
• SPEED 2 duration = 1 hour
• SPEED 3 duration = 0 hours

Operation While the Pump is Running

• If power is connected to the pump motor, pressing any of the following buttons referred to in this section could result in the motor starting.
• Failure to recognize this could result in personal injury or damage to equipment.
• Pressing the Display button will cycle through the current parameters.
• Speed – current run speed.
• Time – current time of day.
• Duration – the amount of time remaining at the current run speed.
• Watts – the amount of watts currently being consumed.
• Pressing any of the Speed Buttons (“1”, “2”, “3”, “Quick Clean”) while the pump is running will act as a temporary override. It will run the speed and duration that is programmed for that button.
• Once completed it will default back to the appropriate point in the programmed schedule.
• Note: If you adjust the speeds of the schedule while the pump is running, it will run the adjusted speed for the rest of the current duration, but will not save the adjustments.
• Exception: Speed and Duration adjustments to QUICK CLEAN will always be immediately saved.

Quick Clean

• If running Quick Clean, pressing the “+” or “-” arrows will change the speed accordingly. Pressing the
• Quick Clean button again within 10 seconds of pressing the “+” or “-” arrows will allow you to adjust the duration of Quick Clean via the “+” and “-” arrows. These changes will be saved immediately and are the new defaults for Quick Clean.
• Pressing the Quick Clean button again will cycle through the two Quick Clean settings. The pump will exit out of editing mode if no additional buttons are pressed within 10 seconds. If Quick Clean is running and you wish to stop the Quick Clean before the duration is completed you can press and hold the Quick Clean button for 3 seconds and the pump will return to the appropriate point in the programmed schedule.

Priming

• This pump is shipped with Priming mode ENABLED. Unless the Priming settings are changed in the menu, be aware that the pump will speed up to the priming speed when the pump is powered on for the first time, and the start/stop button is pressed.

Before turning the pump ON, be sure the following conditions are met:

1. Open the filter air relief valve.
2. Open valves.
3. The pool return is completely open and clear of any blockages.
4. Water in the pump basket.
5. Stand clear of the filter or other pressurized vessels.

• DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start leaking. If this occurs, the damaged seal must be replaced.
• ALWAYS maintain the proper water level in your pool (halfway up the skimmer opening). If the water level falls below the skimmer opening, the pump will draw air through the skimmer, losing the prime and causing the pump to run dry, resulting in a damaged seal.
• Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller, and seal, and may cause property and personal injury.
• Priming will automatically run when the WhisperFlo VS 1500 Variable Speed Pump is started from a stopped state, except when running in Quick Clean mode. Priming will run at 3150 RPM by default and will last for 5 minutes.
• The drive’s screen will display and cycle through the following things “PrI – Priming Speed, PrI – – Remaining Time”.
• Once priming has begun, the speed can be adjusted between 3150 and 1700 RPM using the “+” and “-” arrows. If it is adjusted below 1700 RPM, Priming mode will be disabled and the pump will immediately begin to run at the scheduled speed.
• When priming is disabled and the pump is started from a stopped state, the screen will display, “PrI – OFF” for 10 seconds while running the scheduled speed (See Figure 6). This allows the user time to enable priming mode by pressing the “+” arrow.
• If the user chooses to re-enable priming mode, the pump will then transition from the scheduled speed to 1700 RPM. The user can increase the priming speed from 1700 RPM by pressing the “+” arrow.
• The 5-minute priming countdown timer starts when priming is first engaged.
• The installer should set the priming speed to be sufficient for priming the pump from a fresh install, but not so fast that there is a substantial waste of energy during the 5-minute priming window. The time the pump needs to achieve prime can change based on local environmental conditions such as water temperature, atmospheric pressure, and your pool’s water level. All of these things should be taken into consideration when setting the priming speed, however, in most cases, the pump will not need to run at 3150 RPM to successfully prime itself.
• Please test and verify the chosen priming speeds more than once, letting the water drain from the system in between each test.
• Note: The pump strainer basket should always remain full to the bottom of the inlet to prevent air from entering the system.

Quick Clean

• The WhisperFlo VS 1500 Variable Speed Pump is equipped with a Quick Clean feature, which can be engaged to temporarily run at higher or lower speeds ranging between 300 to 3150 RPM.
• Once the Quick Clean duration has elapsed, the pump will automatically return to the programmed schedule.

Programming Quick Clean:

1. Stop the pump if it is running by pressing the Start/Stop button.
2. Press the Quick Clean button. The LED above the Quick Clean button and the “Speed” parameter LED will flash while editing. See Figure 7.
3. Use the “+” and “-” arrows to adjust the speed in RPM for Quick Clean.
4. Press the Quick Clean button again and the display will change to Quick Clean duration. The “Duration” parameter LED will flash while editing. See Figure 8.
   • Note: The Quick Clean feature does not have a start time.
5. Use the “+” and “-” arrows to adjust the duration in hours and minutes for Quick Clean.
6. Press the Start/Stop button and ensure the LED is illuminated. The pump is now on and will run the speed and duration set for Quick Clean.
   • Note: When the Quick Clean duration ends, the pump resumes the 24-hour schedule at the point where it normally would be running at that time.
   • The Quick Clean duration will not affect the start or stop times of the 24-hour schedule. For example, if Quick
   • Clean runs during a period overlapping with a later part of SPEED 1 and an early part of SPEED 2, the start time of SPEED 3 is not affected.
   • Note: Pressing/Holding the Quick Clean key for more than three (3) seconds will cancel Quick Clean mode.
   • Note: During the Quick Clean mode, the pump will not start with the priming sequence.
   • Note: It is recommended that you do not set the Quick Clean duration to 0 HRS. Setting the Quick Clean duration to 0 HRS will not allow you to change the duration setting while the motor is running.
   • The motor will have to be stopped to change the Quick Clean settings if the duration is set to 0 HRS.

Keypad Lockout

• The key lockout will not prevent the motor from being stopped by pressing the Start/Stop button. It will then be unable to be restarted until the keypad has been unlocked.
• If the motor is operating in Keypad Lockout mode, and being controlled through external controls, it can only run when the Start/Stop LED is illuminated.
• The WhisperFlo VS 1500 Variable Speed Pump user interface has a Keypad Lockout feature to prevent unwanted changes to the settings.
• When locked, the keypad will only accept input from pressing the Display button to cycle the displayed information on the screen and input to stop the motor from a press of the Start/Stop button.
• The keypad can be locked by pressing and holding the“1” button and the Quick Clean button at the same time for at least three seconds. “Loc On” will be displayed if successful.
• To unlock the keypad press and hold the “1” button and the Quick Clean button at the same time for at least three seconds. “Loc OFF” will be displayed if successful.
• Note: While operating in Keypad Lockout mode the motor can still be stopped by pressing the Start/Stop button.
• However, the motor can not be started again until the user unlocks the keypad.

Factory Reset

The drive can be reset to factory settings if necessary. A Factory Reset will wipe out all of the saved user settings that have been programmed, except for the time of day. Be sure that it is necessary before performing a Factory Reset, as the results are immediate.

To perform a Factory Reset:

1. Stop the pump if necessary by pressing the Start/Stop button.
2. Record all of the custom schedule settings using Table 3. You can find these settings by pressing the “1”, “2”, “3”, and “Quick Clean” buttons and cycling through all the screens. Also, write down the Priming Speed.
3. Press and hold the “1”, “2”, “3”, and “Quick Clean” buttons for 3 seconds.
4. The screen will display “FACt rSt” if the factory reset is successful. See Figure 9.
5. Be sure to reprogram the schedule and priming speed after the factory reset. The pump must be turned back on with the Start/Stop button before it will run again. The pump will run the programmed schedule upon initial start-up.

Note: Factory Reset can not be performed from a Keypad Lockout state.

Table 3: User-Programmed Schedules

Control with External Control and Digital Inputs

• The user can run the WhisperFlo VS 1500 Variable Speed Pump with automated external controls, allowing all four programmed Speeds to be controlled remotely.
• The pump has a sealed connector that can be used with the Pentair External Control Wiring Kit (Pentair P/N 356324Z) to run the Speeds using digital input signals.
• When there is an external low voltage signal present on the Speed Digital Input line, the pump will run the speed programmed for that Digital Input. The supplied +5V signal is the recommended input used for external control and Speed Digital Inputs.

Connecting to External Controls Using the Supplied Low Voltage Signal for Digital Control

• The WhisperFlo VS 1500 provides a low-voltage output signal that can be used to trigger its own Digital Inputs. This signal will need to be switched via the External Control system to engage the speed that it is connected to as in Figure 10. This could be an automation relay or switch in another piece of equipment. This feature could be useful for ensuring that the pump is running a certain program when a specific speed is needed to perform a task. The wire included with the External Control Wiring Kit (Pentair P/N 356324Z) will need to be cut to length for the installation. Do not leave excess wire around the installation, and the wire should be supported by something rigid if conduit is not used. At one end of the cable is a custom-molded, watertight connection that plugs into the panel connection on the side of the drive. The opposite end has 6 wires that are defined by Table 1 below. When using the +5V signal supplied by the drive, the speeds should be wired as shown in Figure 10. When there is a low voltage signal present on the Speed Digital Input line the pump will run the speed that is programmed for the speed that is being triggered. The +5V signal supplied via the (red) wire is the suggested input for the Speed Digital Inputs. See Figure 10.
• Note: Any relay can be associated with any Digital Input. Figure 10 shows one of many potential wiring options available to the installer, allowing you to install External Controls in the way that best suits your needs.
• Note: This +5V Signal (red wire) is output from the drive only, and should never be wired to another power supply!
• When a Speed Digital Input is triggered, the LED above the Speed button will begin to blink and the display will toggle between the display parameter and “EC” indicating an External Control is running. The pump will run at this speed as long as the Digital Input trigger is present. This will override the schedule or any user inputs for Speed selections via the keypad. The Display button is still functional along with the Start/Stop button. Once the Digital Input trigger is removed from all of the Speed Digital Input wires, the pump will resume the programmed schedule.

Definition	Signal Range	Wire Colour
+5V Output for Digital Inputs	0 – 20mA	Red
Speed 1 Digital Input	0, 5 – 30V AC/DC	White
Speed 2 Digital Input	0, 5 – 30V AC/DC	Blue
Speed 3 Digital Input	0, 5 – 30V AC/DC	Orange
Quick Clean Digital Input	0, 5 – 30V AC/DC	Brown
Common Ground	0V	Black

Table 2: Automation Control System Input Wiring Chart

• When using an externally supplied low voltage signal as the Digital Input trigger, the wire should be connected as shown in Figure 11.
• The low voltage input needs to be within the range of 5-30V AC or DC. In this case, the red +5V supply from the motor control will not be used.

Note:

• This +5V signal (red wire) is output from the drive only and should never be wired to a voltage supply!
• The external low-voltage signal can be regulated by switches or relays to activate the desired Digital Input. If more than one Digital Input is active at one time then they will be resolved by priority.
• Note: If the pump has been stopped via the Start/Stop button, the pump will not run until the pump is turned back on by pressing the Start/Stop button. If the Start/Stop LED is illuminated, that indicates the pump is on and will run via Digital Inputs.
• Note: If multiple low voltage triggers are present it will be resolved by this priority: Quick Clean, Speed 3, Speed 2, and then Speed 1.

External Control Only Mode

• External Control Only mode will only allow the pump to run from external controls/inputs.
• When this mode is active the programmed pump schedule is deactivated, and user speed requests from the keypad will not be accepted.
• If the pump is stopped a user can still program the speeds for all four Speed buttons.

To activate External Control Only mode:

1. Stop the pump by pressing the Start/Stop button.
2. Activate External Control Only mode by pressing and holding the Start/Stop button for 3 seconds.
3. If successful the LED next to Ext. Control Only will illuminate. See Figure 12.

MAINTENANCE

• To avoid dangerous or fatal electrical shock hazards, turn OFF the power to the pump and remove the plug from the power outlet before working on the pump.
• Do not operate the pump with the trap basket missing or damaged.
• It is essential for the longevity of the pump that regular service and maintenance be carried out.
• The WhisperFlo VS 1500 incorporates high-velocity moving parts and is pumping water containing harsh pool chemicals.
• Some parts which will wear during normal operation and the expected life of the pump.

Follow the instructions below to clean the trap:

1. Switch off power to the pump, close valves in suction and discharge, and release all pressure from the system before proceeding.
2. Remove the trap cover (turn counterclockwise). If necessary, tap handles gently with a rubber mallet.
3. Remove the strainer basket and clean it. Ensure all holes in the basket are clear, flush the basket with water, and replace in trap with a large opening at the pipe connection port (between ribs provided). If a basket is replaced backward, the cover will not fit on the trap body. To clean the transparent cover, use water and neutral soap only. Do not use solvents.
4. Clean and inspect the lid o-ring; reinstall the trap. Clean the O-ring groove on the trap body and replace the cover. To help keep the cover from sticking, tighten your hand tight only.
5. Prime pump (refer to priming instructions).

TROUBLESHOOTING

To avoid dangerous or fatal electrical shock hazards, turn OFF the power to the pump and remove the plug from the power outlet before working on the pump.

Troubleshooting Guide

SYMPTOM	CAUSE	REMEDY
Low water pressure, and low flow from the pump.	Suction leaks / lost prime.	• The pump must be primed; make sure that the pump casing and strainer are full of water. Refer to priming instructions. •    Make sure there are no leaks in suction piping and ensure all o-rings are present and clean. •    Make sure suctions pipe inlet is well below the water level to prevent the pump from sucking air. •    Suction lift of 3 to 6 metres will reduce performance. A suction lift of more than 6 meters will prevent pumping and cause the pump to lose its prime. In either instance, move the pump closer (vertically) to a water source. Ensure that the suction pipe diameter is large enough.
	Low-speed setting.	•    Check speed setting. Refer to the speed selection section of this manual. Reset to default if necessary.
	Clogged pipe/strainer/impeller/filter system.	•    Ensure the trap is not clogged with debris; clean the basket and/or filter. •    Make sure that the impeller is not clogged. This should be checked by qualified personnel only. • The pump may be trying to push too high a column of water. If so, a higher-pressure pump is required.
No water coming from the pump (the pump is working).	Air ingress to the system.	•    Prime the pump. Check that there are no air leaks in the suction piping or fittings. Ensure the strainer lid is airtight and fitted securely. Ensure all o-rings are present.

SYMPTOM	CAUSE	REMEDY
The pump does not work.	Motor fault.	•   Refer to motor fault codes.
	No power at the outlet.	•    Use another electrical appliance that is known to work to check the power outlet.
	Blown fuse / Circuit breaker.	•   Check and call the electrician if necessary.
The pump running too slow.	Low-speed setting.	•    Check speed setting. Refer to the speed selection section of this manual. Reset to default if necessary.
	Motor high-temperature limit exceeded.	•    Ensure motor fins are clean and the fan is intact and free from blockages. Ensure adequate ventilation and reduce ambient temperature.
The pump running at the incorrect speed.	Duration incorrectly set.	•    Change the duration of the desired speed/ step to make sure it’s not “0”.
	Pump in priming mode.	•    Wait for the priming cycle to complete. (3 minutes)
Water leaking from between the casing and the motor.	Casing bolts are not tightened sufficiently; the worn mechanical seal requires replacing.	•    Switch off the power to the pump. Tighten the casing bolts or replace the mechanical seal as required.

• Should problems persist, contact your nearest Pentair Water Service Agent.

Errors and Alarms

• If an alarm is triggered the drive’s LCD screen will display the fault code text and the WhisperFlo VS 1500 Variable Speed Pump will stop running. Disconnect power to the pump and wait until the keypad LEDs have all turned off.
• At this point, reconnect power to the pump. If the error has not cleared then proper troubleshooting will be required. Use the error description table below to begin troubleshooting.

Fault Code	Description
21	The communication link between HMI and motor control has been lost
IA	Power Module over current detected
17	Phase Current Offset out of range
16	Phase Current Imbalance detected
0F	Absolute AC under voltage detected
02	The absolute Phase current limit exceeded
08	The absolute Diode Bridge temperature limit exceeded
04	The absolute Power Module temperature limit exceeded
06	The absolute Power Factor Correction (PFC) temperature limit exceeded
09	DC bus over-voltage detected
0A	DC bus under voltage detected

• 21 – The communication Link between the HMI and Motor control has been lost: Check the jacketed wire on the back side of the keypad inside the drive top cover. Ensure that the 5-pin connector is properly plugged into the socket and that there is no damage to the cable. IA – Power Module over current detected: If this error displays multiple times, then there may be a problem with the pump’s rotating assembly. Please disassemble the pump and investigate to see if there is a problem with the impeller or mechanical seal. Pump Disassembly” for instructions for disassembling the pump. 0F – Absolute AC Under Voltage Detected: This indicates that the supply voltage has dropped below the operating range of 99v. This could be caused by normal voltage variation and will clear itself. Otherwise, there could be excess voltage sag caused by improper installation or improper supply voltage.
• 17, 16, 02, 08, 04, 06, 09, 0A – Internal Errors: These errors can occur based on operating conditions and the UL 60730 required self-diagnostic safety software. If they do not clear after multiple restart attempts the drive should undergo a hard power cycle. Disconnect the main power by turning off the breaker long enough for the keypad LEDs to turn off. After power is reconnected if one of these errors continues to reappear, the drive may need service.
