Waste and Overflow
• Due to limited space between the inner and outer tub shells, use care when selecting your drain kit. Use a cable
driven or toe-tap style. If you ordered your bath with an air system, you MUST use the drain kit included. If access is
available from below during the final installation, it is easier to make precise adjustments in the final location of the tub.
• Remote Mounting Blower - Due to the limited space between the inner and outer shells of the freestanding tubs,
the blower must be remote mounted. In addition to the air hose, there are two electrical connections between
the tub and the blower. Both electrical connections and the air hose exit through the bottom of the bath. It is
always desirable to remote mount the air blower as close to the tub as possible to minimize the loss of heat.
Pipe insulation may be used on the blower hose to minimize heat loss.
NOTE:
Relocating a blower motor still requires a service access for the blower.
NOTE:
All materials needed for the relocation must be supplied by the installer. This includes ordering a longer control
panel cable (P/N 754025-0071A).
A separate circuit, which must be protected by the Ground Fault Circuit Interrupter (GFCI), is required in the remote
location. Electrical connections should be performed by a licensed electrician.
ADDITIONAL INSTRUCTIONS FOR FREESTANDING AIR BATHS
All freestanding air baths may be installed in the center of the room. Keep in mind that the placement of the blower
can be challenging or problematic. All models have a built in access panel for drain installation that you may prefer to
place on the less visible side of the bath. Although each installation may vary, Porcher offers two solutions to blower
placement.
a) Adjacent to the tub: A decorative box to hide the blower may be custom built on site. The box
should always provide access for future servicing of the blower, as well as the required minimum
5" x 7" (127 x 178mm) ventilation panel.
b) Remote mounting the blower: The blower may be remote mounted up to 8' (2438mm) from the bath. The
air hose leading to the blower may be installed under the floor and the blower located inside a
utility or linen closet. Use care not to crush or restrict the airflow in the line in any way. The blower
may also be located underneath the tub. In either case, access to the blower must be provided
for any future service.
1. Disconnect the air hose from the blower and use the provided clamps and coupling to attach
extension
hose.
2. Reconnect hose to blower.
3. The wires leading from the keypad to the blower are standard 6' (1829mm) in length. Up to 12' (3658mm) is
available upon request. The wires on the sensors are 10' (3048mm) in length standard.
4. Secure blower using wood screws through the mounting feet.
Note:
Pipe insulation may be used on the air hose to help retain warmth from the blower. Do not use insulation
within 8" (203mm) of the blower. The blower needs sufficient air space surrounding it for circulation. The blower requires
a separate 110VAC, 15 amp GFCI circuit.
