Installation Instructions

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

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

Circuit-Interrupter (GFCI)*.

Install to permit access for servicing.
A pressure wire connector marked ″Earth/Ground″ is provided within the wiring compartment. To reduce

the risk of electric shock, connect this connector to the grounding terminal of your electric service or supply
panel with copper wire equivalent in size to the circuit conductor supplying this equipment.

A pressure wire connector is provided on the exterior of the pump or control within this unit to permit
connection of a bonding conductor between this unit and all the other exposed metal in the vicinity, as
needed to comply with local requirements.

Grounding is required. The unit should be installed by a qualified service representative, and grounded.

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

beginning installation, including the following requirements.

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. In Canada, install this unit in accordance with

the Canadian Electrical Code, Part 1.

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

Product Information

Electrical Requirements

The 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.

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

NOTICE: For -G2M Music Models: This installation requires installation of an electrical outlet within 24″
(610 mm) of the amplifier location. Refer to the amplifier installation instructions.

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

Product Notices

NOTICE: Keep the area around the blower clean and free of debris. Ensure that the area around the
blower is free of sawdust, insulation, dirt, and other small loose debris. Such material can block the blower
air ducts and reduce the air flow through the blower.

NOTICE: This product contains an automatic water purge mode that turns the blower on for 2 minutes
about 30 minutes after the unit is turned off and drained.

Features

Factory-installed components include a blower motor with power supply cord, check valve (some models),
air piping, and user keypad. -G2M models also include transducers, an amplifier, and a power supply cord.
Other than electrical wiring and plumbing, no assembly is needed.

Important Safety Instructions

READ AND FOLLOW ALL INSTRUCTIONS

SAVE THESE INSTRUCTIONS

INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS

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

DANGER: Risk of accidental injury or drowning. To reduce the risk of injury, do not permit

children to use this unit unless they are closely supervised at all times.

WARNING: Risk of personal injury. To avoid injury, exercise care when entering or exiting the
bath.

WARNING: Risk of electric shock. Do not permit electric appliances (such as a hair dryer, lamp,
telephone, radio, or television) within 5’ (1.5 m) of this bath.

WARNING: The use of alcohol, drugs, or medication can greatly increase the risk of fatal
hyperthermia. Prolonged immersion in hot water may induce hyperthermia. Hyperthermia occurs

when the internal temperature of the body reaches a level several degrees above the normal body
temperature of 98.6°F (37°C). The symptoms of hyperthermia include an increase in the internal
temperature of the body, dizziness, lethargy, drowsiness, and fainting. The effects of hyperthermia
include: (a) failure to perceive heat, (b) failure to recognize the need to exit the bath, (c)
unawareness of impending hazard, (d) fetal damage in pregnant women, (e) physical inability to
exit the bath, and (f) unconsciousness resulting in the danger of drowning.

WARNING: Risk of fetal injury. Pregnant or possibly pregnant women should consult a physician
before using the bath.

WARNING: Risk of hyperthermia or drowning. Do not use the bath immediately following
strenuous exercise.

WARNING: Risk of hyperthermia or drowning. Water temperature in excess of 100°F (38°C) may
cause injury. Test and adjust the water temperature before use.

WARNING: Risk of personal injury. Never drop or insert any object into any opening.

Use this bath only for its intended purpose as described in this guide. Do not use attachments not
recommended by Kohler Co.

The bath must be connected only to a supply circuit that is protected by a Ground-Fault Circuit-Interrupter
(GFCI)*. Such a GFCI should be provided by the installer and should be tested on a routine basis. To test the
GFCI, press the test button. The GFCI should interrupt power. Press the reset button. Power should be
restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI interrupts power to
the bath without the test button being pressed, a ground current is flowing, indicating the possibility of an
electric shock. Do not use this bath. Disconnect the bath and have the problem corrected by a qualified
service representative before using.

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

Care and Cleaning

Do not use powdered cleaners unless the cleaner is fully dissolved in water. Solid substances
could block the airjets.

Do not use full strength bleach or ammonia cleaning solutions. Chemically active cleaning
solutions can damage the bath surface.

Do not use abrasive cleansers or solvents on acrylic surfaces. Abrasive cleaners and solvents can
damage the bath surface.

Wipe out your acrylic bath with a soft cloth after each use.
Avoid detergents, disinfectants, or cleaning products in aerosol cans.

Care and Cleaning (cont.)

Cleaning Your User Keypad and Remote Control

Use a soft cloth to wipe the keypad and remote control after each use. If the surface becomes dirty,
use a non-abrasive soap and warm water to clean.

Maintaining the Airjets

If cleaning the airjets is required due to hard water deposits, use a small between-the-teeth dental
brush and white vinegar. Dip the brush in the vinegar, brush the hole, rinse the brush in clean
water, and then use the wet rinsed brush to rinse the hole.

Before You Begin

These instructions detail both finished deck or rim, and rough
deck installations. Follow only the instructions for your particular
installation.

Observe all local plumbing and building codes.
Supply 1/2″ nominal (5/8″ OD) copper tubing.
Shut off the water supply.
Provide an access panel for servicing the valves.
Instructions are given for installations with 8″ (203 mm) centers.

For wider installations, adjust all roughing-in dimensions and
copper tube lengths accordingly. If the spout is to be installed
more than 24″ (610 mm) from the valves, Kohler Co. recommends
installing a Sioux Chief 652-AD vacuum breaker arrestor. Install
the vacuum breaker arrestor close to the outlet ports of the
valves. For more information, contact Sioux Chief at
www.siouxchief.com.

Products purchased separately may change the valve placement
and alignment.

Leave the protective guard on the spout supply tube until the
spout installation. This is an O-ring sealing surface which may be
damaged if left unprotected.

Plaster guard diameters are approximately 1-5/8″ (41 mm) for the

NOTICE: Plywood is required for rim-mount installations to secure
the spout supply tube. Follow the bath instructions to correctly cut
and position the plywood.

NOTICE: Make sure the plywood will not interfere with other
plumbing connections or installation of the bath.

Install 1/2″ (13 mm) exterior grade plywood if the finished deck
or rim is less than 1/2″ (13 mm) thick, or if the faucet will be
installed directly to the bath rim.
