American Standard Mainstream 2948LC-RHO.020 User manual

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.

4FUNCIONAMIENTO
NOTE: Each whirlpool is shipped from the factory with an air actuator on/off switch and pump with attached
power supply cord. OPERATING THE SYSTEM WITHOUT WATER (DRY RUNNING) WILL CAUSE PUMP
DAMAGE AND VOID THE WARRANTY. Always fill the whirlpool before operating the pump. The air switch is
mounted either on the deck or side wall of the tub.
4a. Fill the Whirlpool: Water level must be at least one inch (25mm) above the highest jet for proper
operation.(See diagram above)
Do not fill whirlpool more than 2/3 full prior to the user completely immersing themselves into unit.
4b. Start Whirlpool: Push on center of button. Button will depress and whirlpool will start.
4c. Stop Whirlpool: Depress and release button and whirlpool will stop.
4d. Air Volume Control Adjustments: Water turbulence is determined by the amount of air mixed with the
water. Rotate the air volume control counterclockwise for more turbulence--clockwise for less.
4e. Adjustable Flow: The water flow action may be adjusted from vigorous to soft by rotating
the nozzle counterclockwise for vigorous and clockwise for soft.
NOTE: You may balance the air volume control and nozzle adjustment for the most desirable condition.
