Electrical

SECTION 1—GENERAL GUIDELINES

Electrical

Be certain ALL electrical work is performed by a qualified electrician and is in compliance with local electrical codes.

ALL electrical connections are to be water resistant.

Grounding

DANGER

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

WARNING

The unit 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, push the test button. The GCFI should interrupt power. Push the resest button. Power should be restored. If the GCFI fails to operate in this manner, GFCI is defective. If the GFCI interrupts power to the bathtub without the test button being pushed, a ground current is flowing, indicating the possibility of an electric shock. DO NOT use this hydro massage bathtub. Disconnect the hydro massage bathtub and have the problem corrected by a qualified service representative before using.

A GREEN-colored terminal (or a wire connector marked “G,” “GR,” “Ground,” or “Grounding”) is provided within the terminal compartment. To reduce the risk of electric shock, connect this terminal or connector to the grounding terminal of your electric service or supply panel with a conductor equivalent in size to the circuit conductors suppling this equipment.

Plumbing

Be certain ALL plumbing work is performed by a qualified plumber.

Some state and local plumbing codes require the installation of a “reduced pressure zone” (RPZ) assembly on both the incoming hot and cold supply lines to prevent back flow contamination into the potable water system. Invacare recommends you check local plumbing code requirements to determine if RPZs are required on your tub installation. RPZs are NOT supplied by Invacare and are to be provided by the customer if required.

The hot water supply to the tub MUST NOT exceed 110° F (43° C) to protect the user from scalding.

When operating water pressure exceeds 55 p.s.i., pressure regulators (similar to the ¾‐ inch Watts U5) MUST be installed.
