IMPORTANT INSTRUCTIONS

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

including the following:

WARNING: Risk of electric shock. Connect only to a circuit protected by a Ground-Fault

Circuit-Interrupter (GFCI)*.

WARNING: Risk of electric shock. A qualiﬁed electrician should route all electrical wiring.

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

WARNING: Risk of electric shock. Do not operate electrical-powered auxiliary devices near water.

WARNING: Risk of property damage. Building materials and wiring should be routed away from

the heat-producing components of the bath.

WARNING: Risk of injury or property damage. Please read all instructions thoroughly before

beginning installation.

NOTICE: Follow all plumbing, electrical, and building codes. In Canada, install this unit in accordance

with the Canadian Electrical Code, Part 1.

NOTICE: Grounding is required. The unit should be installed and grounded by a qualiﬁed service

representative.

NOTICE: If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or

similarly qualiﬁed agent in order to avoid a hazard.

*Outside North America, this device may be known as a Residual Current Device (RCD).

Product Information

Electrical Requirements

WARNING: Risk of burns, ﬁre, electric shock, or injury. Do not operate the heater if the power

supply cord is damaged. For proper guidance to have this product repaired, please call:

1-800-4KOHLER from within the USA or Canada, or 001-800-456-4537 from within Mexico.

This installation must have a Class A Ground-Fault Circuit-Interrupter (GFCI)*. The GFCI protects against

line-to-ground shock hazard. Use a 120 V, 15 A, 60 Hz dedicated service for the bath.

Two 120 V, 15 A (240 V, 15 A in Latin America) GFCI electrical outlets are required. One outlet should be

located within the stud framing and within 24″(610 mm) of the control ampliﬁer. The other outlet must be

within 24″(610 mm) of the junction box mounted to the control board at the lumbar end of the bath. Both

outlets may share the same electrical service, but no other load should be on this circuit.

*Outside North America, this device may be known as a Residual Current Device (RCD).

1. Prepare the Rim-Mount Faucet (Optional)

NOTICE: Before installing a rim-mount bath faucet, refer to the speciﬁcation sheet on the bath product

page at kohler.com for faucet location dimensions for your model.

NOTICE: To accommodate the bath shroud, use ﬂexible connections to attach the water supplies to a

rim-mount faucet.

NOTICE: For rim-mount faucet installations, route the water supply lines high enough to permit access

for making the ﬁnal connections from above the shroud.

Refer to the speciﬁcation sheet on the bath product page at kohler.com to determine the

recommended faucet location and drain model for your bath.

Measure and cut a piece of 1/2″(13 mm) exterior grade plywood to support the faucet. The board

should be 4″(102 mm) wide. The length should extend beyond the width of the faucet holes to

ensure proper support.

Locate the faucet in the desired location on the bath rim. Make sure the faucet trim ﬁts on the bath

rim without overhanging. Make sure there is no interference above or below the rim before drilling

any holes.

Refer to the installation instructions packed with the faucet to determine faucet hole size.

Use a pencil to mark the faucet hole centerlines. Do not drill the holes at this time.

CAUTION: Risk of product damage. To avoid scratching the bath, position a thin piece of cardboard

under any clamps before tightening.

Position the plywood on the underside of the rim, then clamp in place. Make sure the clamps do

not directly contact the ﬁnished surface of the bath.

Carefully drill the faucet holes.

Install the valve according to the installation instructions included with the valve. Do not install the

faucet trim until instructed.

IMPORTANT! Make sure the subﬂoor offers adequate support for the bath.

Remove and discard the thin plastic ﬁlm covering the support blocks.

Temporarily position the shroud in the installation location.

Verify that the shroud is level. If needed, position shims under the shroud.

Using a pencil, trace the shroud hole on the ﬂoor.

Remove the shroud and set aside.

Secure any shims to the ﬂoor.

NOTE: The drain pipe may need to be trimmed, depending on the drain installed.

Position and install a standard PVC or brass bath drain pipe. Install the drain pipe so it extends

2-1/8″(54 mm) above the ﬁnished ﬂoor.

section.

NOTICE: The control ampliﬁer and junction box are each equipped with a cord and plug. A qualiﬁed

electrician must install two GFCI- or RCD-protected, 120 V, 15 A grounded outlets. Both outlets may share

the same electrical service, but no other load should be on this circuit.

Install a 120 V, 15 A grounded outlet within the wall framing and within 24″(610 mm) of the

planned control ampliﬁer location. Route the wires through conduit for this outlet installation.

Circuit-Interrupter (GFCI) or Residual Current Device (RCD) for protection against line-to-ground

shock hazard.

IMPORTANT! The white wire should be connected to the load neutral terminal on the GFCI or RCD

breaker. The green wire is the equipment ground and must be connected to the neutral bus in the main

circuit breaker box.

Follow local electrical codes. Bond in accordance with national and local codes.

Remove the 120 V plug from the end of the electrical cord.
