Plumbing Installation
Ꮨ 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.
NOTE: For this procedure, refer to FIGURE 2.5 on page 21.
1. Refer to Electrical and Plumbing Hook‐up Locations on the Tub on page 17 for the
location of the hot water stub and cold water stub.
2. Measure the location of the drain on the unit.
3. Install the drain in the floor in the appropriate location determined in STEP 2.
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.
7. Connect 2‐inch drains in accordance with local plumbing codes.
8. Assemble hand held shower and disinfectant wands. Be sure to use the washers
supplied.
CAUTION
DO NOT run pump without water in the tub. Serious damage could result. Pump
requires water for cooling.
