AST PCH GMP-025 Series User Manual

 Check desiccant canister. Verify that crystals are blue
in color through window in side of canister. Replace if
crystals are not
blue.
 Check makeup of air lines from desiccant canister to
tank. Remove or repair any blockages.
 Clean inside of tanks, concentrating on any material
built up that might wind up in pumps.
o Re-fill System for Storage
 Fill tanks with compatible oil/lubricant and trigger.
 Close ball valves.
 Start-up Procedure
o Prepare system for loading
 Pre-season startup checks outlined below should be
performed in advance of any intended use.
 AST assumes previous shut-down procedure was
followed.
 Connect air supply & electrical power.
 Open ball valves under tanks
 Test operation of machine. Verify that oil loaded into
machine comes out both ports on the dispense valve
when triggered.
 Operate system until empty.
o Flush system with compatible solvent
 Fill each tank a minimum of 1/3 with a compatible
cleaning solution.
 Operate and observe behavior of system.
*NOTE: Gauges will not read normal pressures while
pumping solvent due to the fact that solvents are less
viscous, therefore requiring less pressure to pump.
#60065-02: Page #12
 Verify that flow is observed coming out of both ports in
dispense valve.
 Operate system until empty. Please note that it is not
harmful to pump machine dry.
 If available, open ball valve under pump inlet block to
verify that all solvent is drained from tanks.
 If possible, temporarily disconnect material hoses from
dispense manifold and allow any trapped solvent to
drain.
 Fill zerks on dispense valve with petrolatum grease until
lubricant coming out of ports is clean.
o Load & Test Material
 Load each material into correct tank. Remember to
keep one lid on while filling the other tank.
 Verify that ball valves above each pump and at outlet
assembly are open.
 Set motor speed to low (30%) and actuate trigger,
operating system until correct material comes out both
ports of dispense valve.
 Observe pressure gauges while filling system. A spike
in pressure would indicate a blockage downstream from
pump.
 Operate system until two streams of material come out
of dispense valve. Release trigger and wipe manifold.
 Attach static mixer to dispense valve. Make several test
shots of material in small cups or on aluminum foil and
allow material to cure.
 Discard static mixer; wipe manifold clean, and re-fill
manifold with petrolatum grease.
 Check cured material for flaws and inconsistencies.
 See “Troubleshooting” section in operator’s manual if
any problems are observed.
