Important Information

WARNING: When using electrical products, basic precautions should always be followed, including the following:

DANGER: Risk of electric shock. To reduce the risk of electrical shock, connect only to circuits

protected by a Ground-Fault Circuit-Interrupter (GFCI) or Residual Current Device (RCD).

WARNING: Risk of electric shock. A qualiﬁed electrician should make all electrical connections.

WARNING: Risk of electric shock. Disconnect power before servicing.

NOTICE: Follow all local plumbing and electrical codes.

Building materials and wiring should be routed away from the blower body and other heat-producing components of the unit.

Install to permit access for servicing.

Product Information

Electrical Requirements

NOTE: If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualiﬁed persons in order to avoid a hazard.

The installation must have a Class A Ground-Fault Circuit-Interrupter (GFCI) or Residual Current Device (RCD). The GFCI or RCD protects against line-to-ground shock hazard. Use a 120 V, 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 electric 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.

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 packed with the bath and the speciﬁcation sheet found on the product page at www.kohler.com.

Product Notices

WARNING: Risk of personal injury or property damage. Unauthorized modiﬁcation may cause unsafe operation or effect performance of the bath with airjets. Do not relocate the 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 product. 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 plug 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.

If the blower motor is installed in an enclosed area, an access panel is required at the blower motor. This panel should be 18″ (457 mm) wide and 14″ (356 mm) high minimum.

Before You Begin

NOTICE: It is not necessary to relocate the blower motor. The option is provided for particular installations where a remote location is practical.

NOTICE: For blower with check valve: Relocate the blower motor and check valve together. Do not relocate one without the other.

NOTICE: DO NOT relocate the control unit. The control unit must remain with the bath.

NOTE: Refer to the Installation Guide packed with the bath for preliminary steps and considerations for

installation of the bath.

NOTE: Your product and piping my appear different than the layout shown above. The installation guidelines and procedures remain the same.

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.

IMPORTANT! Do not cut, remove, or uncoil the coiled piping if attached to the bath.

Cut the middle of the 1-1/2″ PVC pipe located between the tee and the union nut. Disconnect and remove the cable connecting the blower motor and the user interface. Cut the straps holding the blower motor to the support board on the bath. Prepare, install, and secure the bath. Refer to the installation instructions packed with your bath.

3. Reconnect

NOTE: The blower motor must be located within 15’ (4.6 m) of the bath, with no more than six direction changes in piping.

NOTE: If the blower motor is wired to a junction box (Canada units only), the junction box and blower must be moved together.

NOTE: 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.

NOTE: Refer to the ″Before You Begin″ section for other detailed requirements for the blower motor relocation.

At the new blower motor location, install a minimum 1-1/2″ (38 mm) high block (not supplied) for the blower 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. Route PVC or other 1-1/2″ piping (not supplied) between the bath and the blower motor location. For blower with check valve: Install the check valve at the blower motor location. The check valve

must be oriented vertically. Conﬁrm the check valve is oriented with the ﬂow arrow pointing away from the blower motor, and that it is located no lower than 24″ (610 mm) below the bath rim.

For blower without check valve: Connect each previously cut end of the PVC with the provided 1-1/2″ couplings.

Route the provided cable from the new blower motor location to the bath. Use cable ties or other support clips (not supplied) to support the cable.

Connect the cable to the blower motor. The cable connector at the blower should be oriented with the ﬂat side facing up.

Use the provided retaining clip to prevent accidental cable disconnection. Connect the cable to the user interface. Ensure that any wall holes are properly sealed as required by local building or ﬁre codes.

4. Make Electrical Connections

WARNING: Risk of electric shock. To reduce the risk of electric shock, connect the control to a properly grounded Ground-Fault Circuit-Interrupter (GFCI) or Residual Current Device (RCD). This will provide additional protection against line-to-ground shock hazard.

Make electrical connections according to the Installation Guide packed with the bath. Complete the bath installation according to the Installation Guide packed with the bath.
