3. Secure the Whirlpool to the Subfloor
CAUTION: Risk of product damage. 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
Spread a 2” (5 cm) 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
controls and support block locations.
NOTE: Do not use gypsum cement or drywall compound for this application, as they will not provide an
acceptable, durable bond.
NOTE: The pump controls (when the pump banding straps are cut) and support blocks must rest
directly on the subfloor.
Position a piece of plastic drop cloth material on top of the cement or mortar bed. With help,
carefully lift the whirlpool into place, and make sure the pump controls and support blocks do not
rest in the bed material.

4. 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.
5. 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-1397 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-1399 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.

6. 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) or Earth-Leakage Circuit-Breaker
(ELCB). The heater will also need to be connected to a properly grounded Ground-Fault
Circuit-Interrupter (GFCI) or Earth-Leakage Circuit-Breaker (ELCB). 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 licensed 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.
