If a new spring is installed or if the pressure setting of the
pressure relief valve is to be changed from that which the
factory has set, the following instructions must be carefully
followed.
1. Carefully remove the valve cap which covers the
adjusting screw.
Loosen the locknut which locks adjusting screw so the
pressure setting will not change during operation of
pump.
2. Install a pressure gauge in discharge line for actual
adjustment operation.
3. Turn adjusting screw in to increase pressure and out to
decrease pressure.
4. With discharge line closed at a 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.
