IMPORTANT INSTRUCTIONS

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

the following:

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

Circuit-Interrupter (GFCI) or Earth-Leakage Circuit Breaker (ELCB). Grounding is required. The unit

should be installed and grounded by a qualiﬁed service representative.

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

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

WARNING: Unauthorized modiﬁcation may cause poor performance of the valve. Do not make

modiﬁcations to the valve as this could adversely affect the performance of the valve and void the

warranty. Kohler Co. shall not be liable under its warranty or otherwise for personal injury or damage

caused by any such unauthorized modiﬁcation.

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

beginning installation.

NOTICE: Follow all plumbing, electrical, and building codes.

NOTICE: Provide generous, unrestricted service access to the valve. Provide access for servicing the

valve and interface. This access must be located immediately next to the valve. Refer to the roughing in

information.
