B. PUMP BANDING STRAP CUT
NOTICE: This step is necessary to make your
Kohler whirlpool operate more quietly.
1. Use tin snips to cut the two banding straps. These
banding straps secure the pump to the
whirlpool-mounted shipping bracket. When the
banding straps are cut, the pump base and pump
will drop about 1/2” until they rest on the subfloor. If
the pump drops more than 1/2”, be sure the proper
pitch is maintained (with shims under the motor) to
allow the pump to drain through the suction line
when the whirlpool is drained.

2. If the subfloor is level, no adjustments to the pump
are necessary. Proceed to Step 3. If the subfloor is
not level, slide plywood shims between the pump
baseandthesubfloor,butonlyhighenoughtoallow
water to drain out the suction line when the bath is
drained.
