Tools and Materials
Before You Begin
NOTICE: Risk of product damage. The wall surround sections are backed with foam to bring the back of
the wall into contact with the stud framing. This foam is not packing material. Do not remove.
NOTICE: Risk of product damage. Do not install the whirlpool over open floor joists. The basin area
requires no additional support when the subfloor is level and square with the stud framing. Install the
whirlpool on an adequately supported, level subfloor. Use shims for additional support if the subfloor is
uneven.
Observe all applicable plumbing, electrical, and building codes.
This whirlpool is designed for alcove installations.
Upon receipt, check for shortages or damage. Report any shortages or damage immediately.
Do not remove the old fixture before you unpack and inspect the new unit.
Store the whirlpool and wall surrounds in a safe place until you begin installation to avoid damage.
If remodeling, measure the existing framework before removing the old whirlpool to make sure that
the new whirlpool will fit. Make sure that the drain is in the correct location.
Confirm adequate mounting and connection space for the water supply and drain installation.

1. Construct the Framing
Install the Framing
IMPORTANT! Dimensions given in the roughing-in information are critical for proper installation. Refer to
the ″Roughing-In″section for dimensions.
IMPORTANT! For installations with wall surrounds, provide support for the vertical wall flanges at
37-1/4″(946 mm) or 42-1/4″(1073 mm), depending upon the specific model.
IMPORTANT! The framing for each stud should be plumb and square to within 1/8″(3 mm). Shimming
may be required.
Carefully measure the whirlpool.
Construct 2x4 framing using the dimensions specified in the ″Roughing-In″section.
If possible, remove the bottom plate.
Construct an access panel to allow access for servicing the faucets and drain.
IMPORTANT! For installations with wall surrounds, do not allow fiber or other soft insulation to drop
down into the back channel, as this could damage the whirlpool.
For installations with wall surrounds, cover or seal any loose material.
NOTE: If the apron flanges will not be used or have been accidentally broken off during shipping, install
three evenly distributed 2x4 blocks behind the apron location. The blocks will prevent the apron from
being damaged and may be used to secure the apron behind a baseboard.
Construct the Floor
IMPORTANT! Construct the floor of plywood. If the whirlpool is installed over material other than
plywood, friction may cause squeaking over time.
If the subfloor is constructed of a material other than plywood, position the supplied felt pad so all
supports will rest on it.
Verify that the apron flanges can be secured to studs, or install three 2x4 blocks behind the apron
location.
NOTE: The ″Roughing-In″section indicates the location of the drain.
Cut a hole in the floor large enough to fit the drain assembly selected for your installation.

2. Install the Rough Plumbing
NOTE: Provide access to all plumbing connections to simplify future maintenance.
Locate the rough plumbing for the drain according to the roughing-in dimensions.
NOTE: If the plumbing will be installed on the unfinished stud wall, install the supplies after the
surround walls are installed.
Position the water supplies according to the roughing-in information. Cap the supplies and check
for leaks.
Strap the supply lines to the stud framing.
Install the valves according to the manufacturer’s instructions. Do not install the trim at this time.

CAUTION: Risk of personal injury. Do not turn on the power until instructed to do so.
NOTE: The whirlpool is equipped with a cord and plug. All pump and control wiring has been completed
at the factory.
NOTE: Refer to the label near the pump. This label identifies the electrical rating and model number of the
whirlpool.
Install a GFCI-protected, 120 V, 15 A grounded outlet behind the whirlpool and within 24″(610 mm)
of the pump location. No other load should be on this circuit.
Install a bonding (grounding) conductor at the future location of the pump in accordance with any
applicable local codes.
Bond in accordance
with applicable codes.

4. Prepare the Whirlpool
Remove the Apron Access Panel
Insert a flat-blade screwdriver or other prying tool into one of the screwdriver slots.
Use the screwdriver to pry the bottom clip out and release the clip.
Repeat this procedure at the remaining screwdriver slots.
When all bottom clips are released, pull the bottom of the panel away from the apron to release the
remaining clips.
When the bottom of the panel is clear, lower the panel until the top of the panel is clear.
Store the panel in a safe place.
Prepare the Whirlpool
Place a clean drop cloth or similar material in the bottom of the whirlpool.
Install the whirlpool drain and overflow to the unit according to the drain manufacturer’s
instructions. Do not connect the trap at this time.
If the subfloor is not constructed of plywood, position the provided felt pad so the whirlpool
supports will rest on it.
IMPORTANT! Risk of product damage. Do not lift the whirlpool by the apron or apron braces, or by the
piping or pump. Do not use the piping or pump for structural support of the whirlpool.
IMPORTANT! Ensure that each apron brace is connected at all bosses.
IMPORTANT! Use care to properly position the whirlpool in the alcove, as proper placement is critical for
attachment to the studs. Clear all material away from the pump support bracket area and the whirlpool
supports. The pump support bracket and the whirlpool supports must rest directly on the subfloor.
Carefully lift the whirlpool into place.
Make sure the pump support bracket and whirlpool supports do not rest in the bed material.
Verify that the whirlpool is properly positioned with respect to the intended finished wall.
Depending on the installation, the outer edge of the whirlpool should be flush with the intended
finished wall at floor level.
Verify that the whirlpool is level and resting on all supports. The whirlpool should be within 1/8″
(3 mm) of level from side to side, and within 1/4″(6 mm) of level lengthwise. If the whirlpool is
not level, remove the whirlpool and place shims under the supports.

5. Secure the Whirlpool to the Stud Framing
This whirlpool is designed for installation into regularly spaced framing. If there is a gap between the edge
of the whirlpool and the stud, then add shimming to the stud to bring the stud to within 1/8″(3 mm) of the
whirlpool.
CAUTION: Risk of property damage. Do not nail or drill through the whirlpool flange, as this may
crack the flange and cause leaks.
Position the bottom lip of the attachment clip at the side of the stud and under the edge of the
whirlpool. Slide the adjustment clip into place between the center of the stud and the whirlpool.
Bend the tab of the clip over the whirlpool flange with a pair of pliers.
Secure the attachment clip to the center of the stud using either large-head roofing nails or
non-tapered flathead screws.
