Changing Between Colors:
1.
Trigger the gun or use the priming button to move the pump so that it is at the
bottom of the stroke (lowest position).
2.
Prepare the gun:
External Mix
– brush gel coat spray tip and catalyst tip with solvent.
Internal Mix
– flush mix chamber with solvent.
3.
Turn the air motor regulator knob counter clock wise (CCW) to lower the air
pressure to zero.
4.
Open the ball valve at the bottom of resin filter housing. Place the appropriate
container under the ball valve if a return hose is not installed. This will relieve
resin pressure to the supply drum or container.
Note: it is important in order to release fluid pressure in the hose that is no longer
in use.
5.
Release the pressure in the gel coat accumulator by pushing a small dull rod (Allen
wrench) into the top of the accumulator charging valve.
6.
Rotate the ball valve on the catalyst manifold to the open position. This will
relieve catalyst pressure to the supply jug as the air motor is operated up
and down to release or connect to a gel coat color pump.
7.
Close the ball valve at the quick disconnect end of the resin hose assembly.
8.
Disconnect the current resin hose assembly (or color) from the gun assembly and
clean the quick disconnect fittings with solvent.
Note: it is important to keep the quick disconnect fittings clean so that the o-ring
in the female quick disconnect does not become damaged and leak
9.
Connect the new gel coat hose assembly (or color) to the gun assembly and open
the ball valve at the quick disconnect end of the gel coat hose.
10. Push up on the Sleeve holding the coupling Half Shells in place and remove the
coupling Half Shells from the Rod Ends.
