6. Cut the Pump Banding Straps

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 1/2² (1.3 cm) until they rest on the sub¯oor. If the pump drops more than 1/2² (1.3 cm), shim under the pump support bracket so there is a 1/2² (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 sub¯oor with screws or lag bolts (not provided).
