Operation
I.Pressure Relief Procedure
The system remains pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the gun, or splashing of any fluid, follow this proce- dure whenever you
•Are instructed to relieve pressure
•Stop spraying
•Check or service any system equipment
•Install, clean, or change spray nozzles
1 . Be sure the pump air regulator (6a) is still open. Close the master air valve (A) to relieve pump air . pressure.
2 . Close both air regulators (6a,6b).
3 . Turn the
4 . Trigger the spray gun into a waste pail to relieve fluid pressure.
5 . Turn off and unplug the heater (3).
II.Flush the Pump Before First Use
Flush with a solvent compatible to your fluid. Consult the fluid manufacturer’s literature for recommenda- tions. See Flushing on page IO.
III.Priming the System
See Fig. 7.
1.Put the suction tube (15) in the prepared fluid.

5 . Open the fluid pressure regulator (44) (fully clockwise).
6 . Turn the needle valve (5) ail the way out (counterclockwise)
7 . Close the gun and pump air regulators (6a,6b) (full counterclockwise).
8 . Connect the air line (C) to the pump.
9 . Open the master air valves (A).
10.Slowly raise the pump air regulator (6a) pressure to 20 to 30 psi (1.4 to 2.1 bar). The pump will cycle quickly until is it primed. When it is primed, the pump will stall against pressure. Now set the pump air pressure to 40 psi (2.8 bar). When fluid flows from the drain hose, turn the
11.Hold the gun against and aimed into a grounded metal waste pail. Trigger the gun, and slowly open the fluid regulator (44). The gun will emit air until the fluid arrives. When fluid flows freely, release
the gun trigger. | . |
