GENERAL INSTALLATION INFORMATION
Carefully uncrate and inspect your new bath for any
shipping damage. If such damage is found, report it to
your vendor immediately.
After inspection and during installation, protect the bath
from construction damage. After installation, and before
enclosing with wallboard, tile, etc., water test the unit
and check for leaks.
If a whirlpool, do not make modifications to the whirlpool
system or remove pump from factory mounting. This
could adversely affect the safety and performance of the
whirlpool and void the warranty. Do not handle or move
the whirlpool by the pump, motor, or piping system.
Fittings (bath filler, shower arm, etc.) are not provided
with the bath and must be ordered separately. Framing
and enclosing materials are provided by others. Check
for availability of optional American Standard wall tiling
bead (required for recess installations).
Protect all finished surfaces of the whirlpool during
construction and installation using a drop cloth.

FRAMING AND INSTALLATION
THE VARIETY OF INSTALLATIONS POSSIBLE FOR THIS BATH MAY REQUIRE FRAMING PROCEDURES OTHER THAN THOSE SHOWN.
LOCATE STUDS AS REQUIRED. INSURE ROUGH DIMENSIONS ARE PROPER, PLUMB AND SQUARE. FOR WHIRLPOOLS, PROVISION MUST
BE MADE IN ALL INSTALLATIONS FOR AN ACCESS OPENING FOR SERVICING PUMP AND CONTROLS.
THE FOLLOWING PROCEDURE MUST BE USED FOR ALL INSTALLATIONS: STRINGER OR PIER HEIGHT SHOULD BE AS INDICATED. THE
SUMP OF THE BATH IS SUPPORTED BY INTEGRAL FEET AND NO ADDITIONAL SUMP SUPPORT IS REQUIRED. ONCE THE BATH IS IN
PLACE, THE FEET SHOULD BE SHIMMED ACCORDINGLY, SO THAT THE RIM OF THE BATH CONTACTS THE STRINGER OR PIER BUT
SUPPORTS NO WEIGHT. ANY FINISH MATERIAL, SUCH AS TILE OR WALL BOARD, MUST BE SELF-SUPPORTING IF IT CONTACTS THE
RIM OF THE BATH.

ELECTRICAL INSTALLATION INSTRUCTIONS
All wiring must be performed by a licensed electrician in accordance with the national electrical code and all other
applicable codes.
WARNING:
When using electrical products, basic precautions should always be observed, including the following:
1. DANGER: RISK OF ELECTRIC SHOCK
Connect only to a circuit protected by a ground-fault circuit interrupter.
2. Grounding is required. The unit should be installed by a licensed electrician and grounded.
3. Install to permit access for servicing.
4. All building materials and wiring should be routed away from the pump body and heater (if equipped).
The whirlpool should be installed on a 120 vac, 15 amp dedicated circuit. The circuit should be hard-wired from the
electrical power supply panel. The circuit must be a three (3) wire circuit from the electrical supply panel. A grounded
neutral wire and a third wire, earth ground, are essential.

DRAIN CONNECTION AND SYSTEM TEST
Using recommended drain opening, connect whirlpool drain to waste line. Tighten all drain joints securely. Check the
pump couplings and make sure they are hand-tight. Clean the whirlpool and fill with water to a point 2" above the top of
the highest jet. Recheck the pump couplings and make certain that they are not leaking. (Although the pump couplings
are factory tightened and inspected, some loosening may have occured during transit.) Make sure the whirlpool is
connected to the electrical supply and turn the whirlpool on. Check for leaks around all piping connections while the
whirlpool is running.
POST INSTALLATION CLEAN-UP

for copper conductors
only. Always follow
local and national
electrical codes
Remove all construction debris from bath. Tile grout can be removed with a wooden popsicle stick or tongue depressor.
Do not use wire brushes or any other metal implement on bath surface.
Post installation clean-up generally can be completed using warm water and liquid dishwashing detergent. Stubborn dirt or
stains may be removed using granular Spic and Span® mixed with water.
Painter's naphtha can be used to remove excess adhesives and/or wet oil-base paint.
HARSH CHEMICALS SHOULD NEVER BE USED ON ACRYLIC SURFACES.
Abrasive cleaners must not be used since they will scratch and dull the surface. Dulled areas can be restored by rubbing
with a white automotive-type polishing compound and waxing with a liquid wax.
