Rev.20170601 V1.0E HPC INSTALLATION & OPERATION MANUAL 8
PRIOR TO INITIAL START-UP, be sure that:
・ Coolant level in the machine reservoir is sufficient to supply the HPC.
・ Any shut-off valves in the inlet lines are open, and the high pressure lines are not blocked.
・ All fittings are tight.
・ The oil level in the HPC pump reservoir is within the acceptable range.
・ The Pressure Regulating Valve adjusting bolt on the outlet of the pump is backed out to the full counter-
clockwise position to relieve spring tension. This assures that the pump starts under minimum pressure.
・ Either a bag filter or pleated cartridge element has been installed, the o-rings and wire filter hold downs have
seated properly, and the filter lids have been tightened securely.
・ All air has been purged from both 70-00DF(SF) filter canister.

PROCEDURE FOR PURGING AIR FROM FILTER CANISTER
1. F ilter Drain Valves should be closed - valve handle horizontal.
2. Command HPC System OFF . Command coolant system "ON". Only the supply pump should be running
at this time.
3. Watch the clear Air Purge/Drain Hoses until only coolant is being discharged. Any air in the canister should
have command machine coolant system "OFF". Check the entire system for signs of leakage .
Command machine coolant system "OFF" .
NOTE: Pressure gauge pointers should be steady. A bouncing or fluctuating pointer may indicate an excessive
amount of air is entrained in the coolant supply to the HPC.
