1. Prepare the Site
NOTICE: Do not support the whirlpool by the rim.
NOTICE: Provide adequate floor support.
NOTICE: Measure your actual product for site preparation. Note the model number located on the
whirlpool pump, then visit the product page at kohler.com for additional information.
Make sure the flooring offers adequate support for your whirlpool, and verify that the subfloor is
flat and level.
The whirlpool can be installed in a drop-in, flush, alcove, or tile-in installation. Construct 2x4 stud
framing designed for your particular installation. Frame the floor, or construct a frame for a raised
installation.
Use the template packed with the whirlpool to carefully lay out and cut the rough deck material.
For flush-mount installation, allow for the thickness of the planned deck material.
Position the plumbing. Cap the supplies, and check for leaks.
2. Prepare the Whirlpool
Install the drain to the whirlpool according to the drain manufacturer’s instructions. Do not connect
the trap at this time.
Position a clean drop cloth or similar material in the bottom of the whirlpool. Be careful not to
scratch the surface of the whirlpool.

3. Secure the Whirlpool to the Subfloor
NOTICE: Do not lift the whirlpool by the piping or pumps, or use the piping or pumps for structural
support of the whirlpool.
Choose the installation option that best applies to your particular installation. Follow the
appropriate instructions.
If the subfloor is not level, shim the whirlpool support blocks as necessary.
Option for Using a Cement or Mortar Bed
NOTE: Do not use gypsum cement or drywall compound for this application, as they will not provide an
acceptable, durable bond.
Spread a 2” (51 mm) thick layer of cement or mortar on the subfloor where the whirlpool will be
set. This will help secure, level, and support the unit. Clear all the material away from the pump
control locations.
NOTE: The pump controls (when the pump banding straps are cut) must rest directly on the subfloor.
With help, carefully lift the whirlpool into place, and make sure the pump controls do not rest in
the bed material.
Insert the drain tailpiece into the trap. Make sure the whirlpool is level and resting on all support
blocks.
Option for Using Construction Adhesive
Apply a generous amount of high-quality construction adhesive to the bottom of the support blocks.
With help, carefully lift the whirlpool into position.
Insert the drain tailpiece into the trap. Make sure the whirlpool is level and resting on all support
blocks.
Option for Using 100% Silicone Sealant
With help, carefully lift the whirlpool into position.
Insert the drain tailpiece into the trap. Make sure the whirlpool is level and resting on all support
blocks.
Apply a continuous bead of 100% silicone sealant around the entire rim of the whirlpool.
Clear space

4. Secure the Whirlpool to the Stud Framing
Option for Integral Flange Models
Drill a small pilot hole through the nailing-in flange at each stud. Add shims between the nailing-in
flange and the studs as needed to eliminate gaps.
Nail 1/4” (6 mm) thick furring strips to the studs to shim out to the edge of the nailing-in flange.
Use #6 large-head galvanized nails to secure the nailing-in flange to the studs.
For tile ledge installations, size and install a pressure-treated wood batten along the nailing-in
flange. Pre-drill nail holes through the wood batten and nailing-in flange before securing with
galvanized nails.
Stud Framing
Nail 1/4" (6 mm) furring
strips to the studs.
Drill a small pilot
hole through the
nailing-in flange.
Use #6 large-head galvanized
nails to secure to the studs.
Install a pressure-treated wood

5. Cut the Pump Banding Straps
IMPORTANT! This step is necessary to make your KOHLER whirlpool operate more quietly.
Use tin snips to cut the two pump banding straps from each whirlpool pump.
NOTE: Do not raise the pumps higher than they were before you cut the pump banding straps. If the
pumps are raised too high, they will not prime properly. Make sure the rubber isolation feet are in place.
To minimize whirlpool noise and vibration, be sure the pumps are not in direct contact with the
whirlpool after the pump banding straps are cut. The pump controls contain rubber isolation feet to
reduce pump noise.
6. Install the Plumbing
CAUTION: Risk of property damage. Ensure a watertight seal on the whirlpool drain.
Connect the drain to the trap according to the drain manufacturer’s instructions.
NOTICE: An access panel will simplify future maintenance.
K-1360 only: Connect the hot and cold water supply lines to the integral fill valves according to
local codes. An additional hole is pre-drilled in the bath shell for the handshower. Install the
handshower at this time. Connect the end of the handshower hose to the open port of the transfer
valve (beneath the bath rim). Make sure the transfer valve stem is rotated fully clockwise. The
transfer valve includes an integral vacuum breaker that protects both the fill spouts and the
handshower from water backflow.
K-1365 only: Install the faucet valving according to the faucet manufacturer’s instructions. Connect
the valving to the whirlpool fill ports (spouts) according to local codes.
All models: Do not install the faucet trim until instructed. Open the hot and cold water supplies,
and check the supply connections for leakage.
Run water into the whirlpool, and check the drain connections for leakage.
Rotate the transfer valve stem, and check the handshower connections for leakage.

7. Make Electrical Connections
NOTE: The product model number is printed on a label on the pump side of the overflowing bath. This
label also identifies the electrical rating of the whirlpool. These whirlpools come equipped with two
wiring junction boxes and are designed to operate between 208 VAC and 240 VAC at either 50 Hz or 60
Hz.
WARNING: Risk of electrical shock. Make sure the power has been disconnected before
performing the following procedures. Refer to the “Important Information” section.
WARNING: Risk of electrical shock. To reduce the risk of electrical shock, connect the pump to a
properly grounded Ground-Fault Circuit-Interrupter (GFCI)*. The heater will also need to be
connected to a properly grounded Ground-Fault Circuit-Interrupter (GFCI). This will provide
additional protection against line-to-ground shock hazard. Two 208-240 V, 20 A, 50/60 Hz dedicated
circuits are required.
IMPORTANT! The load neutral is not used. There should be no connection to the load neutral terminal
on the Ground-Fault Circuit-Interrupter (GFCI) breaker. The green wire with the yellow stripes is the
equipment ground and needs to be connected to the neutral bus in the main circuit breaker box.
The control and heater have been pre-wired at the factory. A qualified electrician should make
routine service connections to each of the junction boxes.
Connect service to the junction boxes. Both junction boxes contain blue, brown, and green with
yellow stripe colored wires.
Follow local electrical codes. Bond in accordance with national and local codes.
A wiring harness has been pre-wired at the factory, allowing communication between the keypad,
all features, and the control. No additional wiring is required, but ensure that all wires are securely
fastened.
Bond in accordance with nation and local codes.
Open bonding lugs are located at the top of the
junction box.
