AST PCH GMP-025 Series User Manual

o Tank/Material Feed System
 Clean & inspect tank lid sealing gaskets. Repair with
RTV Silicone as necessary.
 Check desiccant canister. Verify that crystals are blue
in color through window in side of canister. Replace if
crystals are not blue.
 Check makeup 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.
 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 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 full 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.
 Verify that flow is coming out of both ports in dispense
valve.
 Operate system until empty. Please not that it is not
harmful to run 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 valve 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.
#60065-02: Page #11
 Attach static mixer to dispense valve. Make several test
shots of material in small cups or on aluminum foil and
allow curing.
 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.
The following is the recommended procedure for storing
equipment for an extended period of time. Please note that
some items included in this procedure are not included with all
supplied equipment. Please use all safety devices such as but
not limited to gloves and eye protection. When working with
solvents do so in a well-ventilated area free of combustible
items. Take every effort not to mar or damage any surfaces
that come in contact with materials.
 Pump Unit Dry
o Pump remaining material.
 Remove static mixer and/or spray attachment.
 Operate machine until no material is being dispensed.
Check that hoses are allowed to drain completely
(hoses should lead “downhill” towards dispense valve).
 Clean dispense valve & reapply layer of petrolatum
grease.
o Flush System
 Use only a cleaning solution most effective for removing
your material. Consult material manufacturer for
recommendations. Carefully observe all health and
safety precautions listed on all labeling.
 Fill each tank a minimum of 1/3 with a compatible
cleaning solution.
 Set pump speed control to slow setting.
 Operate machine until cleaning solution begins coming
out of machine.
 Allow machine to sit for a period of time, depending on
effectiveness of cleaning solution, not more than one
hour. Most solvents will not damage any component
unless allowed to remain in system.
 Continue pumping cleaning solution into container until
machine is again empty. Observe cleaner as it is being
pumped. As solution is pumped, it should appear to
become clean. If this is not observed, the same
cleaner, after impurities have settled, can be reloaded
into machine and procedure repeated – if
it is pumped
out immediately
. Do not allow any settled material back
into system.
o Tank/Material Feed System
 Clean & inspect tank lid sealing gaskets. Repair with
RTV Silicone as necessary.
