Priming the Unit:
Priming Solvent: (Internal Mix Systems Only)
1.
Open solvent tank lid and fill ¾ full. Install lid on tank and close the relief valve
located on the top of the lid. Set flush tank pressure at 50 to 60 psi (3.5
– 4 bar).
2.
Check for leaks and fix as necessary.
3.
Push the flush valve on the side of the gun block to test solvent flush.
Select Gel Coat Pump Color:
1.
Connect the Carriage Assembly to the desired Gel Coat fluid section / Color (see
“Changing Between Colors” above).
2.
Connect the accompanying gel coat hose assembly to the gun and open the ball
valve at the quick disconnect end.
Priming Catalyst to Gun:
1.
Gun preparations:
Internal Mix: (Pro Gun) Tighten packing nuts on the gun and trigger the gun 10 to 15
times. Snug packing nuts again and repeat gun triggering, repeat this process three
or four times. Remove nozzle and mixer from the mix chamber.
External Mix: Remove the catalyst and spray tip from the front of the gun.
2.
Tighten the catalyst packing nut – 1/8 to 1/4 of a turn to snug packing.
3.
Fill the two gallon catalyst jug ¾ full, purge the air out of the catalyst feed line by
slightly tilting the catalyst jug.
4.
Open the recirculation valve on the catalyst manifold.
5.
Remove the pivot pin for catalyst drive linkage. Using the catalyst drive hand prime
catalyst back to the jug through the recirculation valve. Do this till there is no air in
the tube.
6. Close the recirculation valve on the catalyst manifold.
7.
Lock or hold the gun in the open position over an appropriate container. Remove
the pivot pin from the catalyst drive linkage. Use the catalyst drive to hand prime
catalyst out to the gun until a steady stream is achieved. Do not reinstall pivot pin
at this time / open the catalyst recirculation valve at the catalyst manifold to
prevent over pressurizing the catalyst system.
