Operation, Care and Cleaning

Spray Operation
With pump primed, prime/spray valve in closed position
and no air to the spray gun;
1. Trigger spray gun and increase pressure at
fluid regulator to obtain a steady fluid stream
approximately 6 to 10 inches (152-254 mm) long.
2. If fluid stream cannot be obtained, increase pump
air regulator pressure.
3. To maintain a steady fluid stream, pump air
regulator pressure should be kept approximately
15% higher than fluid regulator pressure.
4. Increase atomizing air pressure at regulator slowly
until spray pattern evens out with gun approximately
6 to 8 inches (152-203 mm) from the surface to be
sprayed.
Note: Maximum air pressure at regulator must be kept
at 43 psi active air (spray gun trigger open) or below to
maintain HVLP compliance.
This pump is designed to operate within a wide range of
pressures. To minimize overspray, always spray at the
lowest possible pressure that produces a well atomized
pattern.
Note: Atomizing air pressure will drop if the air line to
the spray gun is extended. The addition of a spray gun
regulator (installed at the bottom of the spray gun) will
show exact atomizing air pressure.
To avoid static sparking and material splashing,
always shut off atomizing air to gun and firmly
hold a metal component of the gun to the side of a
grounded metal pail during flushing operations.
Shut Down and Care Procedure
1. Shut off atomizing air at regulator by turning dial
counter-clockwise.
2. Remove fluid intake assembly from material.
3. Trigger spray gun to empty material remaining in
hose.
4. Open prime/spray valve to remove any remaining
material from the pump.
5. Insert fluid intake assembly and return line into
cleaning material.
Note: Cleaning material should be a compatible
thinning material for the product sprayed.
6. Close prime/spray valve to route cleaning material
through fluid hose and spray gun.
7. Trigger spray gun to flush material line and spray gun
until fluid appears clean.
8. Remove fluid intake assembly from cleaning material
and continue to trigger spray gun until material is
completely drained from system.
9. Release spray gun trigger and open prime/spray
valve to flush remaining fluid from pump.
10. Remove return line from cleaning material.
11. Wipe unit clean and return all regulators to zero (0) psi.
Note: Unit should be cleaned after every use to avoid a
build up of material in the fluid line and pump assembly
and to ensure proper system operation. Refer to the
Spray Gun Owner's Manual for additional spray gun care
and cleaning procedures.
