If a new spring is installed or if pressure setting of pressure
relief valve is to be changed from that which the factory has
set, the following instructions must be carefully followed.
1. Carefully remove valve cap which covers adjusting
screw.
Loosen locknut which locks adjusting screw so pressure
setting will not change during operation of pump.
2. Install a pressure gauge in discharge line for actual
adjusting operation.
3. Turn adjusting screw in to increase pressure and out to
decrease pressure.
4. With discharge line closed at point beyond pressure
gauge, gauge will show maximum pressure valve will
allow while pump is in operation.
In ordering parts for pressure relief valve, always give
model number and serial number of pump as it appears on
nameplate and name of part wanted. When ordering springs,
be sure to give pressure setting desired.
