OPERATION
The TPM Relief Valve System is set as follows:
Set the red pressure indicator on the PMD control valve to a position slightly above the normal operating
pressure (even before you are flowing water)
Once you have reached normal operating pressure (as indicated on your master pressure gage) slowly move
the adjusting handwheel counterclockwise until the QG relief valve opens and the amber indicator light
comes on.
Then turn the handwheel about 1/2 turn clockwise until the indicator light goes off. The relief valve will now
operate at the “’set pressure”.
When the pump is not in operation, the handwheel should be turned clockwise back to a position slightly
above the normal operating pressure.
Remember that the red indicator on the panel is only a ROUGH indication of what pressure the TPM is set
for. Always use the above procedure to properly set the system,
