SECTION 2—PARTS AND INSTALLATION

Plumbing Installation

DANGER

Be certain all plumbing work is performed by a qualified plumber and is in

compliance with local codes.

WARNING

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 (46° C) to protect the

user from scalding.

CAUTION

Purge water lines. Hot and cold lines MUST be purged (blown down) to clear lines

of debris prior to connection. Valves and spray heads may become inoperable and/

or damaged if lines are not properly cleared. Items damaged in this way are not

covered under the warranty.
When operating water pressure exceeds 55 PSI, pressure regulators (similar to the

¾-inch Watts U5) MUST be installed.

NOTE: For this procedure, refer to FIGURE 2.5 on page 21.

4. Purge water lines. Hot and cold lines MUST be purged (blown down) prior to

connection, to clear lines of debris.

5. Install On/Off valves at wall and use unions between valves and stubs.

6. Connect hot and cold supply lines to ¾‐inch copper pipes found on back of tub in

accordance with applicable building codes.

CAUTION

DO NOT run pump without water in the tub. Serious damage could result. Pump
