Operation
Starting and Adjusting the Pump
1. Fig. 4. Open all fluid shutoff valves (5–two). Make
sure Air Regulator (CC) is fully closed.
2. Open the spray gun at the last gun station and
keep it open while starting the pump.
3. Open the bleed-type master air valves (W, AA).
4. Slowly open air regulator (CC) until the pump
starts. The air regulator controls the pump speed
and fluid outlet pressure.
5. Adjust the fluid pressure to the lowest setting
necessary to get the desired results. Higher pres-
sures may not improve the spray pattern and will
cause premature component wear. Use the air
regulator (CC) to adjust the pump speed and fluid
pressure until the spray is completely atomized.
6. To adjust the spray pattern, follow the complete
instructions in your gun manual.
7. When you have achieved the desired spray pat-
tern, release the gun trigger. The pump will contin-
ue to cycle as long as air is supplied.
8. One at a time, open any other guns in the system
to purge air from the lines.
NOTE: In a circulating system, the pump will continue
to cycle as long as air is supplied. In a direct supply
system, the pump starts when the gun is opened, and
stops when the gun is closed.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause
component rupture and serious injury,
never exceed the specified maximum air input
pressure to the pump (see Technical Data on
page 26).
CAUTION
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. If your
pump is running too fast, stop it immediately and
check the fluid supply. If the container is empty and
air has been pumped into the lines, refill the con-
tainer and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.
Shutdown
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
1. Relieve the pressure.
NOTE: If the system will remain inactive for an ex-
tended period, flush with a compatible solvent before
shutting down. See Flushing on page 13.
