Before You Begin

CAUTION: Risk of product damage. Do not lift the whirlpool by the piping or pump, or use the

piping or pump for structural support of the whirlpool.

We recommend this whirlpool for drop-in or ﬂush installation.

Inspect the whirlpool for damage before you begin installation.

You must install this whirlpool to an adequately supported, level subﬂoor.

Model K-1397 features an integral ﬁll system using dual ﬁll ports at both sides of the Waterfall, and

preinstalled valving.

Model K-1399 allows you to use the ﬁll valving of your choice - you can use the pre-installed dual

ﬁll ports or a separate ﬁll spout if you desire. Conﬁrm adequate support for a rim-mounted faucet,

if used; large faucets that may be inadvertently used as a means of support are not appropriate or

safe for this installation.

Consult local and national codes.

1. Prepare the Site

NOTICE: Adequate ﬂoor support must be provided. Consult the roughing-in sheet packed with your

whirlpool for speciﬁc ﬂoor loading requirements.

CAUTION: Risk of product damage. Do not support the whirlpool by the rim.

Make sure the ﬂooring offers adequate support for your whirlpool, and verify that the subﬂoor is

ﬂat and level.

The whirlpool should be installed in a drop-in or ﬂush installation. Construct 2x4 stud framing or

concrete or brick support designed for your particular installation. Frame the ﬂoor, or construct a

frame or support for a raised installation in accordance with the roughing-in information packed

with the whirlpool.

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 according to the roughing-in information packed. 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.

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.

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 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 high-quality silicone sealant around the entire rim of the whirlpool.

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.

Run water into the whirlpool, and check the drain connections for leakage.

Rotate the transfer valve stem, and check the handshower connections for leakage.

6. Make Electrical Connections

NOTE: The whirlpool model number is printed on a label near the whirlpool pumps. This label also

identiﬁes the electrical rating of the whirlpool. These whirlpools come equipped with two wiring

junction boxes and will only operate at 220-240 V and at 50/60 Hz.

WARNING: Risk of electric shock. To reduce the risk of electric shock, connect the pumps and heater

to properly grounded Ground-Fault Circuit-Interrupters (GFCI’s) or Earth-Leakage Circuit-Breakers

(ELCB’s). This will provide additional protection against line-to-ground shock hazard. Two 220-240 V,

20 A, 50/60 Hz dedicated circuits are required.

WARNING: Risk of electric shock. Make sure the power has been disconnected before performing the

following procedures.

The whirlpool controls and system have been prewired at the factory. A licensed electrician should

make routine service connections to the junction boxes.

Connect service to the junction boxes. The junction boxes contains blue, brown and green with a

yellow stripe colored wires and ground lugs. Use one service for the pump controls, and another for

the heater. A communication cord from the heater to the primary control has been prewired at the

factory.

Provide separate equipment earthing conductors for the earth lugs located inside the junction boxes.

The earthing conductors must not be connected to any current-carrying conductors. Follow local

electrical codes.

Bond in accordance with national and local codes.

Wiring harnesses have been prewired at the factory. They allow communication between the

keypad, all features, and the controls. No additional wiring is required, but ensure that all wires are

securely fastened.

NOTE: Each wiring harness includes an antenna for the remote control. Do not alter or damage this

antenna during installation.
