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. Turn 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.
