THE BEST BATH OR SHOWER EXPERIENCE?

THE ONE NOBODY INTERRUPTS.

Thank you for buying an American Standard

bath or shower product.

We’re so grateful you did, and you will be too. Not just while you’re waking

up each morning, but also every time a dirty gardener, sweaty soccer player,

or muddy dog gets cleaned up. How do we know? Just like you, we’ve lived

with that same beautiful chaos called life for almost 150 years. We believe

that while every home should appreciate in value, we never forget the

sentimental value that grows from enjoying life in the heart of home—

your kitchen and bath. That’s why we love your stories and ideas; they help

us innovate with products that make your life easier.

INSTALLATION INSTRUCTIONS

Thank you for selecting American Standard – the benchmark of ﬁne quality for over 150 years. To ensure this

product is installed properly, please read these instructions carefully before you begin. Certain installations may

require professional help. Also be sure your installation conforms to local codes.

INSTALLATION PREPARATION

• Please unpack carefully and identify all parts needed for installation by using the Box Contents page as a

reference. Inspect the product and report any damages or missing parts immediately to customer care by

calling 800-442-1902.

• Mainstream Whirlpool dimensions are nominal and meant for a standard 60"(1524 mm) alcove. Alcove sizes

may vary based on stud and wall material thickness. Please double check your measurements prior to starting

your install.

• Wear protective equipment during installation to avoid injury.

• Please keep these instructions for after care and customer service details.

!WARNING: PRODUCT IS HEAVY AND REQUIRES TWO PEOPLE FOR INSTALLATION.

BEFORE YOU BEGIN

Inspect your product thoroughly before installing. Take extra care in handling surfaces

of the bath and use only non-abrasive cloths to avoid scratching. Observe all local plumbing

and building codes.

IMPORTANT SAFETY INSTRUCTIONS

INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS

READ AND FOLLOW ALL INSTRUCTIONS!

!WARNING: Risk of personal injury. Do not permit children to use this unit without adult supervision.

!WARNING: Risk of personal injury. Do not operate this unit without the guard over the suction ﬁtting.

!WARNING: Risk of electric shock. Do not permit electrical appliances (hair dryer, telephone, radio, etc.)

within 60 inches (1524mm) of this unit.

!WARNING: Risk of hyperthermia and possible drowning. People using medications and/or having ad-

verse medical history should consult a physician before using this product.

!WARNING: Risk of personal injury. Do not overﬁll unit before entering. Entering tub when ﬁlled more than

2/3 can cause overﬂow and slippery conditions. Exercise caution when entering and exiting.

!WARNING: No Food or Alcoholic Beverages. Use of your bathtub immediately after meals is not

recommended. Avoid alcohol consumption before or during bathing. Alcoholic beverages can

cause drowsiness or hyperthermia resulting in loss of consciousness or even drowning.

!WARNING: Pregnancy. If you are or think you may be pregnant, consult your physician before using

the bathtub.

Never drop or insert any object into any opening.

Use this unit only for its intended use as described in this manual. Do not use any attachments not

recommended by American Standard.

The unit must be connected only to a supply circuit that is properly protected by a ground-fault

circuit-interrupter (GFCI). Such a GFCI should be provided by the installer and should be tested on a routine

basis. To test the GFCI, push the test button. The GFCI should interrupt power. Push the reset button. Power

should be restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI interrupts power

to the bathtub without the test button being pushed, a ground current is ﬂowing, indicating the possibility of an

electric shock. Do not use this hydromassage bathtub. Disconnect the hydromassage bathtub and have the

problem corrected by a licensed electrician before using.

A pressure wire connector is provided on the exterior of the motor unit to permit connection of a no. 8 AWG

solid copper bonding conductor between this unit and all other electrical equipment and exposed metal in the

vicinity, as needed to comply with local requirements. To reduce the risk of an electric shock, connect this con-

nector to the grounding terminal of your electric service or supply panel with a conductor equivalent in size to

the circuit conductors supplying this unit.

GENERAL INSTALLATION INFORMATION

IMPORTANT

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. Before installation, and before enclosing with wallboard, tile, etc., the bath must be ﬁlled

with water and operated to check for leaks that may have resulted from shipping damage

or mishandling. 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 are not provided with

the bath and must be ordered separately. Framing and enclosing materials are provided by others.

For electrical requirements, refer to section titled “Whirlpool Electrical Installation Instructions”.

Check for availability of optional American Standard wall tiling bead (required for recess installation).

Protect all ﬁnished surfaces of the whirlpool during construction and installation using a drop cloth.

!WARNING: DO NOT LIFT WHIRLPOOL BY THE PIPING HARNESS AT ANY TIME.

1INSTALLATION AND FRAMING INSTRUCTIONS

The variety of installations possible for this whirlpool may require framing procedures other than those shown.

Locate studs as needed. Ensure roughing-in dimensions are proper, plumb and square. Provisions must be

made in all installations for an access opening for servicing the pump and controls. It is strongly recommended

that an additional opening be provided for access to the drain components.

1a. Position the whirlpool into the installation opening and level the deck in both directions. On models

2948LHO/RHO, shim the integral support feet if necessary. Mark the ﬁnal position of the underside of

the deck by tracing a line on to the studs (see Figure 1).

1b. Remove the whirlpool and attach a 1 x 4 stringer to the studs, with the top of the stringer touching the

traced line.

!The rim of the bath must not support weight.

1c. Install drain components to the whirlpool following the drain installation instructions. Before replacing your

whirlpool for ﬁnal installation, be certain that an opening has been provided in the sub-ﬂoor for the drain.

See the roughing-in drawing and Table 1 for suggested opening size (shadowed) and location dimensions.

The drain/overﬂow of the bath extends below the bottom of the bath. Note that this requires a cutout in

the ﬂoor.

!The ﬂoor structure beneath the bath must be able to support a total weight of bath, water, and bather.

Refer to Table1 on page 5 under total weight for your model.

2INSTALLATION AND FRAMING INSTRUCTIONS

This bath must be supported along its entire bottom. Use mortar as bedding material (do not use sand or

foam). Apply enough mortar to support the complete bottom of the bath. After the mortar has been poured,

and before it sets, position whirlpool or bath within recess until the rim is leveled against the leveling stringers

(see “Typical Recess Installation”) shown above.

!The rim of the bath must not support weight. Allow the mortar material to completely harden before

applying weight to the rim or bottom of the bath. Any ﬁnish material such as tile or wall board must be

self-supporting if it contacts the deck of the bath.

2948LHO/RHO Replace whirlpool and re-shim the integral support feet, shimming the entire length of the

support feet. Secure the shims using construction adhesive, silicone, mortar or equivalent materials. While not

a necessity, the use of a foundation base consisting of cement, mortar, or grout will help provide a solid and

secure installation.

!The rim of the bath must not support weight. If foundation base is used, allow the bedding material to

completely harden before applying weight to the rim or bottom of the bath. Any ﬁnish material such as tile

or wall board must be self-supporting if it contacts the deck of the bath.
