Operation
Purging and Priming
Always keep the spray gun locked in the off position while
purging the system.
If this unit is new, it is shipped with test fluid in the fluid section
to prevent corrosion during shipment and storage. If you are
going to spray with latex paint, this fluid must be thoroughly
cleaned out of the system. For spraying with solvent-based
paint, thorough cleaning of this material is not necessary.
If it is already in service, you will need to purge the water or
solvent used in cleanup.
Purging and Priming the Pump for Latex Paint
1. Secure the return hose into a waste container.
2. Place a bucket of soapy water under the suction tube.
3. Turn the pressure control
knob fully
counterclockwise to
reduce the pressure to its
lowest setting.
4. Set the PRIME/SPRAY
valve to PRIME.
5. Move the ON/OFF switch
to ON.
6. Slowly turn the pressure control knob clockwise to
increase the pressure until fluid starts to come out of the
return hose. Use only enough pressure to keep the fluid
coming out.
7. Turn the pressure control knob fully counterclockwise to
its lowest setting when the test fluid is purged and soapy
water is coming out of the return hose.
8. Remove the bucket of soapy water from the suction tube
and replace it with a bucket of clear water.
9. Increase the pressure to the minimum necessary to keep
fluid flowing until clear water is coming out of the return hose.
10. Turn the pressure control knob fully counterclockwise to
its lowest setting.
11. Remove the bucket of water
from under the suction tube
and replace it with a
container of latex paint.
12. Increase the pressure slowly
until paint is coming through
the return hose.
13. Remove the return hose
from the waste container and
place it in its operating position above the container of
latex paint.
14. Keep circulating the paint through the system until the
paint coming out of the return hose is free of air bubbles.
15. Turn the pressure control knob fully counterclockwise to
its lowest setting.
The pump is now purged. Skip to
Purging and Priming the
Spray Hose.

Purging and Priming for Solvent-Based Paint
Thorough cleaning is not necessary when using solvent-based
paint. All you need to do is purge the test fluid from the
system.
1. Secure the return hose into a waste container.
2. Place a full container of paint under the suction tube.
3. Turn the pressure control knob fully counterclockwise to
reduce the pressure to its lowest setting.
4. Set the PRIME/SPRAY
valve to PRIME.
5. Move the ON/OFF
switch to ON.
6. Slowly turn the
pressure control knob
clockwise to increase
the pressure until fluid
starts to come out of the return hose. Use only enough
pressure to keep the fluid coming out.
7. Turn the pressure control knob fully counterclockwise to
its lowest setting when the test fluid is purged and paint is
coming out of the return hose.
8. Remove the return hose from the waste container and
place it in its operating position above the container of
solvent-based paint.
9. Keep circulating the paint through the system until the
paint coming out of the return hose is free of air bubbles.
10. Turn the pressure control knob fully counterclockwise to
its lowest setting.
The pump is now purged. Skip to
Purging and Priming the
Spray Hose.
Purging and Priming the Spray Hose
After the pump is purged and primed, you must do the same
for the spray hose.
If a metal container is used, ground the
gun by holding it against the edge of
the container while flushing. Failure to
do so may lead to a static electric
discharge which may cause a fire.
1. Turn the pressure control
knob fully
counterclockwise to its
lowest setting.
2. Set the PRIME/SPRAY
knob to SPRAY.
3. Unlock the spray gun.
4. Turn the pressure control
knob slowly clockwise to increase pressure.
5. Trigger the gun into a waste container until all air, water or
solvent is purged from the spray hose and paint is flowing
freely.
6. Turn the pressure control knob fully counterclockwise to
its lowest setting.
7. Set the PRIME/SPRAY knob to PRIME and trigger the gun
into the waste container to be sure that no pressure is left
in the hose.
8. Lock the spray gun off.
