Some products, specifications, and services mentioned in this manual are described in pending patent applications or are protected by patents.

ELECTRICAL CONNECTIONS:

• Never drop or insert objects into any openings.
• The Thermomasseur® must be connected only to a supply circuit that is protected by a 20 amp class A ground fault circuit interrupter (GFCI). Optional therapies such as Chromatherapy and/or 2nd heated backrest and/or WarmTouchShell® must be connected to a supply circuit that is protected by a 15 amp class A ground fault circuit interrupter (GFCI). This interrupter is supplied by a certified electrician and must be tested on a regular basis in accordance with manufacturer’s instructions. The GFCI ground must be connected. If defective, do not use the Thermomasseur®. Disconnect immediately and call a certified electrician.
• Use 12 AWG (for 20 amp dedicated circuit) and 14 AWG (for 15 amp dedicated circuit) copper conductors that resist temperatures of at least 194 °F (90 °C)
• Canada only: for permanently connected units. A green-colored terminal (or a wire connector marked g., gr., ground or grounding) is provided within the terminal compartment (not applicable if unit supplied with an electric plug).
  To reduce the risk of electrocution, connect this terminal or connector to the grounding terminal of your electric service or supply panel with conductor equivalent in size to the circuit conductors supplying the equipment and be 12 AWG or more.
• All electrical connections must be carried out by a certified electrician and must respect federal, provincial/state, and local building codes and regulations.
• Install in accordance with manufacturer’s installation instructions.
•  For Geysair-equipped baths using remote turbine installation (not mounted on the bath), grounding continuity must be tested between the bath grounding terminal and the bath power supply. Failure to perform the grounding continuity test could result in serious personal injury.

WATER LEAK TEST – IMPORTANT

• Once plumbing is fully installed and before beginning any other work, fill the ThermoMasseur® with water to overflow level and wait 30 minutes. Check all plumbing hook-ups and bath for leaks. BainUltra® is not responsible for any water damage caused by improper installation (see Warranty section in the Owner’s Manual).

SITE PREPARATION

PLUMBING

• See faucet manufacturer’s specifications for zoning and plan water supply location accordingly.
• Position drain according to bath’s technical specifications.
• Leave access to Geysair jonction hose.

WARNING

• Baths from SCALA™ collection cannot be drilled for faucet installation.
  Faucets must be freestanding or wall-mounted models.

BEDDING

• Before installing, ensure that the floor underneath the bath can support 1500 lb (680 kg). No special bedding installation is recommended by manufacturer, the bathtub can sit directly on the floor.

There is a technical specification sheet for each BainUltra® ThermoMasseur® which includes information such as necessary dimensions of site before installation.
If you do not already have the technical specifications, download it from the BainUltra® Web site at: bainultra.com or call us at: 1 800 463-2187.

TURBINE – REMOTE INSTALLATION

1. A 1 ½ inch ID pipe has to run from the tub, back to the turbine location. This pipe can be PVC Tigerflex (spa hose) or rigid PVC or ABS
2. Maximum distance is 15 feet from the tub, indoors, in a room temperate setting (not outdoors or in a non-temperature controlled area)
3. Minimum size for an enclosure for the turbine: 16’’ x 16’’ x 16’’
4. Make sure to leave access for servicing needs
5. The enclosure should have a minimum 4×2 inch opening so the turbine works properly. Not doing so will starve the blower of air. It will eventually fail and void its warranty
6. A 20 Amp GFCI (12AWG) 120V dedicated line is needed for the turbine (GeysAir is powered by the turbine). If you have additional options on the bath (one or more) a second dedicated line is needed, 15 Amp GFCI 120V (14AWG)

GEYSAIR®

1. Geysair is installed on the tub from the factory and must not be relocated. It gets its power from your turbine. So per your local electrical code, you may have to use a solid core wire (14AWG) and run it in between the blower location and the tub. This may require a proper conduit for high voltage wires if installed in a cement slab for example.
2. Geysair connects to the hot water line that you are providing to your faucet at the tub. It uses a 3/8 compression thread.

LED (CHROMATHERAPY) AND 2nd HEATED BACKREST

1. The power modules (inMix module, Litestreme) have to be installed next to the turbine.
2. The wires have to be sent from the tub back to the turbine location.
   LED: Low voltage for the Chromatherapy .
   2nd heated backrest: High voltage (1 wire 14AWG).

ELECTRONIC CONTROL (KEYPAD)

1. A large majority of our freestanding tubs require that the keypad be installed on the wall and not on the tub. You can use silicone to adhere it to your wall instead of the bracket and wing nuts.
2. The infra-red receiver is normally installed a couple of inches away from the keypad, side by side.
3. Both the infra-red and keypad should be in line of sight from the tub sitting position. But they can be separated.
4. The keypad and infra-red receiver (low voltage wires) each have a 15 foot cable that has to run from the wall position back to the turbine. Extensions are available if needed.
5. You can use a conduit to feed these wires as well if needed.

ISLAND TUB DRAIN

1. The ITD is strongly recommended when you have no access under the floor.
   Refer to: INSTALLATION WITHOUT ACCESS UNDER THE FLOOR, page 11.
