Priming the Unit:
Priming Gel Coat to Gun:
NOTE: The resin pump was tested using oil. It may require up to 1/2 gallon (1
– 2
liters) of gel coat to be run through the unit to purge any remaining oil from the
system.
1.
Fill the Reservoir cavity 1/2 full with TSL oil or suitable oil.
2.
Insert the gel coat suction wand into container of gel coat. Clamp or tape the return
hose coming from the bottom of the in-line filter to the pickup wand and into the
drum / pail.
3.
Remove the Catalyst Tip and Spray Tip from the front of the gel coat gun.
4.
Position the gun over an appropriate container and with the gun trigger locked in
the open position, slowly increase pump regulator pressure until pump is running at
a slow but steady rate. Allow pump to run until a steady stream of gel coat is being
dispensed.
5.
Close the gun and brush the front of the gun head clean with solvent.
6.
Slowly increase gel coat pump pressure to 100 psi (7 bar). Allow the unit to set
under static load for 15 to 30 minutes to seat the resin packing set.
Turn the pump regulator to zero. Slowly open the ball valve at the bottom of the resin
filter to drain the fluid pressure
