with local electrical codes.
ALL electrical connections are to be water resistant.
Grounding
DANGER
Grounding is required. The unit should be installed by a qualified service
representative and grounded.
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
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 supplying this equipment.
Plumbing
Be certain all plumbing work is performed by a qualified plumber and is in compliance
with local codes.
with local codes.
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.
