Priming with Optional Suction Set
(P/N 0508194A)
1. Attach the suction set to the pump.
a. Remove the hopper return tube fitting. Screw the suction
set return tube fitting into the return tube port on the side
of the pump.
i
Do not over-tighten. Hand tighten only. Some
threads will be visible even when fully tightened.
b. Align the nut on the suction set with the threaded inlet
valve on the pump block.
c. Thread the suction hose onto the inlet valve on the pump.
i
Make sure the threads are straight and the suction
set fitting turns freely on the inlet valve. Do not
cross-thread.
d. Thread the return tube onto the return tube fitting on the
pump.
2. Place the suction set into a container of paint.
3. Turn the pressure control knob counterclockwise to the
minimum pressure setting.
Attention
Always reduce the pressure to zero by triggering
the spray gun before changing the position of the
PRIME/SPRAy valve. Failure to do so may cause
damage to the paint pump diaphragm.
4. Turn the PRIME/SPRAY valve to PRIME.
5. Move the pump ON/OFF switch to the ON position.
6. Turn the pressure control knob clockwise to between half
and full pressure. Let the unit prime 1 to 2 minutes after paint
begins to flow through the return hose until no bubbles are
present.
7. Turn the pressure control knob counterclockwise to the
minimum pressure setting.
8. Move the pump ON/OFF switch to the OFF position.
Attention
If the pressure control knob is reduced to zero and
the PRIME/SPRAy valve is still on SPRAy while the
pump is operating, there will be high pressure in the
hose and spray gun until the PRIME/SPRAy valve is
turned to PRIME or until the spray gun is triggered to
relieve the pressure.
