5. Secure the Whirlpool to the Stud Framing

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.

6. Cut the Pump Banding Straps — Models With Support Blocks

IMPORTANT! This step is necessary to make your Kohler whirlpool operate more quietly.

NOTE: Do not raise the pump higher than it was before you cut the pump banding straps. If the pump is

raised too high, it will not prime properly.

Use tin snips to cut the two pump banding straps. When the banding straps are cut, the pump support bracket and pump will drop about 1/2″ (1.3 cm) until they rest on the subﬂoor. If the pump drops more than 1/2″ (1.3 cm), shim under the pump support bracket so there is a 1/2″ (1.3 cm) gap between the pump and bracket to allow for proper drainage.

To minimize whirlpool noise and vibration, be sure the pump is not in direct contact with the shipping bracket after the pump banding straps are cut.

Secure the pump support bracket to the subﬂoor with screws or lag bolts (not provided).

Framing

Water-Resistant Wall Material

Finished Wall

Whirlpool

Apply silicone sealant to the joint between the whirlpool and the finished wall.

On models with an integral apron, access the pump by gently prying at the apron edge with a screwdriver or dull knife to remove.

10. Complete the Finished Wall

NOTE: If your whirlpool has an integral apron, it is designed so the ﬁnished wall material (1-1/2″ [3.8 cm] maximum) will overlap the apron columns. The ﬁnished ﬂoor material (2″ [5.1 cm] maximum) should butt against the apron.

If you have not already done so, carefully remove the protective tape from the whirlpool rim. If necessary allow for deck-mounted valves and spout. Cover the framing with water-resistant wall material. Seal the joints between the whirlpool rim edge

and the water-resistant wall material with silicone sealant. Tape and mud the water-resistant wall material. Install the ﬁnished wall to the water-resistant wall

material. Seal the joints between the whirlpool rim and the ﬁnished wall material with silicone sealant.

Install the faucet trim according to the trim manufacturer’s instructions.

11. Removing the Apron

Your whirlpool may be equipped with an integral apron which allows you convenient access to your whirlpool controls. To remove the apron, insert the edge of a ﬂat blade screwdriver or dull knife under the edge of the apron panel. Be careful not to scratch the visible surfaces. Gently pry up at one end. Carefully pull the apron panel off.

To reinstall, bow the apron slightly so both ends can be inserted at the same time. Gently press in the center of the panel to secure the apron in place.

12. Clean-Up After Installation

When cleaning up after installation, do not use abrasive cleansers, as they may scratch and dull the whirlpool surface. Use warm water and a liquid detergent to clean the surface.

Remove stubborn stains, paint, or tar with turpentine or paint thinner. Do not allow cleaners

containing petroleum distillates to remain in contact with any whirlpool surfaces for long periods of time. Remove plaster by carefully scraping with a wood edge. Do not use metal scrapers, wire

brushes, or other metal tools. Use a powder-type detergent on a damp cloth to provide mild abrasive action to any residual plaster.
