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 Packing Nut cavity ¾ full with TSL oil or suitable oil.
2.
Insert the gel coat suction wand into container of gel coat. Clamp or tape the resin
return hose coming from the bottom of the in-line filter to the resin pickup wand and
into the drum.
3.
With the gun 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.
4.
Close the gun:
Internal Mix: Flush the mix chamber clean.
External Mix: Brush the front of the gun head clean with solvent.
5.
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.
6.
Turn the pump regulator to zero. Slowly open the ball valve at the bottom of the
resin filter to drain the fluid pressure.
Note: the above procedures will need to be performed for each fluid section/color.
Charging the Gel Coat Surge Chamber: (If applicable)
1.
Open the ball valve below inline resin filter.
2.
To charge the resin surge chamber, use the air hose with the female quick
disconnect (charging hose) and insert over the male quick disconnect at the top of
the resin surge chamber. Push down on female quick disconnect for 5 to 10
seconds and disengage.
3.
Close ball valve below in-line filter.
