Blower Information
• The blower motor must be located within 15' (4.6 m) of flexible piping from the bath air harness in
the center of the bath. This limitation is for total pipe length and applies to any direction changes
and elbows. There can be no more than six changes of direction. There should be as few direction
changes as possible.
• The blower motor must be mounted horizontally at least 1-1/2" (38 mm) above the floor. Do not
mount the blower motor with the blower motor discharge 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 a free space of about 30 cubic
feet (0.8 cubic meters) for cooling.
• The check valve must be relocated with the blower motor. 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. DO NOT relocate the control unit. The control unit must remain with the unit.
• Use 1-1/2" PVC or equivalent rigid 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.
• Use PVC unions or other means of making the installation maintainable.
• 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.
