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.

Specifications WARNING: Risk of electric shock. A licensed electrician should route all electrical wiring. WARNING: Risk of electric shock. Disconnect power before servicing.

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

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