Installation Guide Continued

Before You Begin (cont.)
Relocate the blower motor as close to the bath as possible to maximize bath performance. The
blower motor must be located within 15’ (4.6 m) of the bath, with no more than six direction
changes in piping.
If the blower motor is wired to a junction box (Canada units only), the junction box and blower
must be moved together.
The blower motor must be oriented horizontally, and installed to a support block that is the same
height as the original mounted location relative to the bath, or 1-1/2″ (38 mm) above the floor.
For blower with check valve: At the new location, the check valve must be no lower than 24″ (610
mm) below the rim of the bath. The check valve must be within 12″ (305 mm) of the blower motor.
The check valve must be oriented vertically with the flow arrow pointing up.
The blower motor must have adequate ventilation for cooling and airflow. Do not install the blower
motor closer than 1” (25 mm) from the wall or other objects. Provide approximately 30 cubic feet
(0.8 cubic meters) of minimum air space for cooling.
Use 1-1/2″ PVC or equivalent piping.
The piping installation must meet the requirements of local plumbing or building codes. Ensure that
the installation does not reduce the fire rating of any walls.
Piping must be supported at intervals along the length in accordance with local codes.
Ensure that the blower motor location is clean and free of dust or debris.
If appropriate, install an additional access panel for blower motor maintenance.
In accordance with local codes, the keypad cable must be supported by cable ties or support clips at
intervals along the length of the bath. The cable must not rest on wet surfaces or floors that are
subject to flooding.
All material needed for the relocation must be supplied by the installer. This includes everything
below the subfloor up to the couplers included in the kit.
1. Prepare Site
Prepare the site for the bath installation and blower motor installation. Refer to the installation
instructions packed with your bath.
Install the required access panel to service the blower motor.
Prepare routing paths for the PVC piping and the keypad cable. Follow all applicable building, fire,
plumbing, and electrical codes.
