Check if the mounting feet are compressed too tightly.
Is the mounting surface flexible? If so, it may be adding noise.
Check for loose head/screws.
If the pump is plumbed with rigid pipe, then it may transmit noise more easily.
Please do follow the instruction manual to install the product. Any action outside what is recommended in this
manual may bring damage to the pump. Any inappropriate installation or operation that causes the pump damage

- Page 2 Setup REPAIR KITS 1. The pump may be mounted in any position. If mounted vertically, the pump head should be in the down position to avoid leakage into the motor casing in the event of a malfunction. 2. Secure the feet, but do not compress them. Overtightening the securing screws may reduce their ability to dissipate noise and vibration.
