NOISY
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.
ABOUT THE BYPASS
Please consult a professional technician in the case that the bypass needs adjustment.
Improper adjustment of the bypass may damage the pump.
The bypass comes preset for optimal operation of the pump. If your application calls for a
different setting for the bypass, you may change it yourself. Carefully tighten the screw to
increase or loosen the screw to decrease the minimum operational pressure of the bypass.
CAUTION
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 is not covered by warranty.
