DANGER
Be certain all plumbing work is performed by a qualified plumber and is in compliance with local codes.
WARNINGS
Be certain all plumbing work is performed by a qualified plumber and is in compliance 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.
CAUTIONS
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.
