Product Information
Electrical Requirements
The installation must have a Class A Ground-Fault Circuit-Interrupter (GFCI) or Residual Current Device
(RCD). The GFCI or RCD protect against line-to-ground shock hazard. Use a 120V, 15 A, 50/60 Hz dedicated
service for the bath with airjets.
An equipment grounding terminal is provided in the field wiring compartment. To reduce the risk of
electrical shock, this terminal must be connected to the grounding means provided in the electric supply
panel with a conductor equivalent in size to the circuit conductors supplying this equipment.
For Canadian installations, install the bath with airjets in accordance with Canadian Electrical Code, Part I.
The electrical rating of the bath is printed on a label near the blower motor. You can also find the electrical
requirements from the Installation Guide and Roughing- in page packed with the bath in the Product
Information section.
Product Notices
WARNING: Risk of personal or property damage. Unauthorized modification may cause unsafe
operation or effect performance of the bath with airjets. Do not relocate the bath blower motor, or
make other modifications to the bath system in the absence of kit or other published instructions, as
this could adversely affect the performance and safe operation of the bath with airjets. Kohler Co.
shall not be liable under its warranty or otherwise for personal injury or damage caused by any
such unauthorized modification. Refer to the ″Before You Begin″ section for blower motor relocation
requirements, recommendations, and section coverage information.
NOTICE: Keep the area around the blower motor clean and free of debris. Ensure that the area around
the blower motor is free of sawdust, insulation, dirt, or other small loose debris. Such material could clog
the blower motor air ducts and reduce the air flow through the blower.
Connections and Service Access
NOTICE: Provide unrestricted service access to the blower motor. You must provide access for servicing
the blower motor and controls. The access must be located immediately next to the blower motor. Study
the roughing-in information packed with the bath with airjets.

Product Information (cont.)
Before installation, ensure that there is proper access to the blower motor and final connections. If the blower
motor is installed in an enclosed area, an access panel is required at the blower motor. This panel should be
18″ (45.7 cm) wide and 14″ (35.6 cm) high minimum.
Tools and Materials
•
Flat blade screwdriver.
•
Drill and bits as required to install the blower mounting fasteners.
•
1-1/2″ (3.8 cm) PVC or other rigid pipe, with fittings, unions, PVC cement or equivalent fastening
method, and support clips, as required, not provided.
•
Flathead wood screws, concrete anchors, or other fasteners for mounting the blower motor, four (4)
each, not provided.
•
Cable ties or other support clips for supporting the keypad cable.
Before You Begin
NOTICE: It is not necessary that the blower motor and check valve be relocated. The option is provided
for the case that a particular installation makes this effort practical.
NOTICE: The blower motor and the check valve must be relocated together. Do not relocate one without
the other.
For your convenience or accessibility, the blower motor and check valve can be mounted in a
remote location. Choose a space as close to the bath as possible to maximize bath performance. Plan
and prepare for the relocation. Pay attention to the following requirements and recommendations:
NOTE: Refer to the Installation Guide packed with the bath for preliminary steps and considerations for
installation of the bath.
•
The blower motor must be located within 15’ (4.6 m) of rigid piping from the bath air harness. 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 2″ (5 cm) 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” (2.5 cm) 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″ (61 cm) below the rim of the bath. The check valve must be within 12″
(30.5 cm) 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 whirlpool.
•
1-1/2″ PVC or equivalent rigid piping should be used.
•
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.
•
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.

motor support.
Use the blower motor as a template to mark the location of the four mounting bolts or screws.
Drill four pilot holes for the blower motor mounting screws.
Fasten the blower motor to the support board.
Install the check valve at the blower motor location. The check valve must be oriented vertically.
Ensure that the check valve is oriented with the flow arrow pointing away from the blower motor,
and no lower than 24” (61 cm) below the bath rim. If appropriate, reuse the screws previously
removed from the blower motor and the check valve.
Install and support PVC or other 1-1/2″ rigid piping (not supplied) between the blower motor
location and the bath air harness.
At the bath end, provide a union or other serviceable connection to the existing air harness.
