Specifications:

The FFVH32 is an 18kw 3 phase industrial electric fan heater.
The appliance is connected to a 400v 32Amp 3P+N+E 50Hz fused power supply and comes fitted with the appropriate appliance inlet. A neutral is required. This appliance requires an Earth connection.
The machine is not phase rotationally sensitive !
The FFVH32 is fitted with two high quality forward curved fans which deliver up to 2300m3h of air.
The FFVH32 is fitted with an onboard thermostat as standard. It is also supplied with a remote thermostat as standard. (See P5).
The FFVH32 is supplied with locking castors to the front of the machine.

Setup and operation:

To start:

• Please note ! the control panel is to the side of the appliance and the controls are located beneath a protective plastic inspection window. The inspection window can be secured with thumb screws.(See P8).
• Site the appliance on a firm level surface and apply the castor brakes. Do not operate the unit without applying the brakes.
• Ensure that the air distributor support and air distributor are securely fitted. Do not operate the machine without the air distributor support! (See P6).
• Connect the machine to the appropriate power supply.
• Switch the fan rocker switch to I. ( please note! the heat rocker switches will not operate the heating elements unless the fan switch is on).
• Switch the heat rocker switch to I- 12kw or I+II- 18kw.
• Set the thermostat to the desired temperature.

To stop:

• Switch the heat rocker switches to 0 and allow the fan to run for a minimum of five minutes to cool the machine. Failure to follow this procedure will damage sensitive components and invalidate the warranty.
• Switch the fan rocker switch to 0 when the heat has dissipated.
• If the heat has not fully dissipated the fan may ‘run on’ automatically. (see P8).
• If the heater is not in use disconnect from the power supply.

Using the remote thermostat:

• Set the onboard thermostat to 0. Please note! failure to set the onboard thermostat to 0 will prevent the remote thermostat from operating.
• Lift the retaining catch and remove the protective cap from the remote thermostat socket. The thermostat socket is located in the recess at the side of the machine. (See P8)
• Fit the remote thermostat plug to the socket and secure in place with the retaining catch.
• The remote thermostat is now ready for use.
• Always refit the protective cap when not in use.

Using the fabric air distributor:

The FFVH32 is supplied with a fabric air distributor. This will distribute warm air through 360 degrees and is ideal for workshop environments.
The air distributor can be modified by the operator to distribute air at head height or above head height.
The centre section of the air distributor can be removed via the zip fastenings and the two remaining sections zipped together.

The air distributor should never be used without fitting the air distributor support.
The air distributor support should be used on both the long disitributor and short distributor.
Failure to fit the support could result in damage to the appliance and will not be covered by the warranty.

Using the fabric air distributor cont’d:
The fabric air distributor is supplied with a duct clip that needs to be threaded through the cloth loops at it’s base before fitting.
The air distributor support should be fitted over the outlet spigot before fitting the air distributor. This is a push-fit connection.
The air distributor is then fitted over the outlet spigot ensuring the clip is located below the beading. The clip should be tightened.

The air distributor support prevents the fabric air distributor from collapsing onto hot metal parts in the event of a malfunction or incorrect appliance shutdown.
Do not operate the appliance without the air distributor support.

Protective /safety devices:

• The FFVH32 is fitted with a safety limit thermostat. This is a fail-safe device. Should the maximum design operating temperature be exceeded it will shut down the heating elements. This device requires a manual reset and should only operate in the event of a fault. Any activation of this safety device should be investigated by a competent engineer.
• The FFVH32 is fitted with a limit thermostat. Should the maximum operating temperature be exceeded it will shut down the heating elements and leave the fan running. This device will automatically reset once the temperature falls to an acceptable level.
• The machine is fitted with an automatic fan run-on thermostat. If the machine is shut down without running on fan only for 5 minutes to cool down, this device will activate and allow the fan to keep running. This should not be used to routinely shut down the machine.
  It should be noted that after operating at high temperatures it could take a significant amount of time for the fan run-on thermostat to reset.

Safety limit thermostat:
Checking and resetting the safety limit thermostat:
Should the safety limit thermostat activate the causes should be investigated.

• Remove the black plastic screw cover from the safety limit thermostat.
• If the pink reset button is noticeably pronounced the reset has activated.
• To reset the thermostat press the pink reset button. Allow the machine to fully cool down before resetting.
• Always replace the screw cap after resetting.

Removing the filter:
The filter requires periodic cleaning/ replacement.
To access the filter remove the four M5 cross head bolts located in each corner of the front grill panel.
Lift the grill panel away from the appliance and remove the filter.
Heavy dust deposits can be removed from the filter with low pressure compressed air.
If the filter is very dirty it will need replacing.
Care needs to be taken when cleaning the filter. It is delicate and can be easily damaged.
Ensure the air filter is correctly orientated when re-fitting. The air direction arrow should be pointing into the machine.
When maintenance is complete refit the filter and grill panel.
Do not operate the appliance without the grill panel.
