Side Entry Whirlpool Tub 20 Part No 1118387
Plumbing Installation
DANGER
Be certain all plumbing work is performed by a qualified plumber and is in
compliance with local codes.
ƽ 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.
