Operation
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
l
Are instructed to relieve pressure
l
Stop spraying
l
Check or service any system equipment
l
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
3 .
Turn the 3-way valve
(9)
to
Drain.
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.

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
(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
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 3-way valve to
Circu-
late.
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.
