Bring an air line from your compressed air supply to the pump location. Be sure the air is dry and filtered. Install a bleed–type master air valve (A) upstream from the pump. Another master air valve (32) is supplied with the package. When the bleed–type master air valve is closed and the pump air regulator (31a) is opened, the valve relieves all air pressure to the system.

I. How to use the air–assisted airless

spray gun.

With

an air-assisted airless spray gun, the spray tip shapes the fluid into a fan pattern. Air from the air cap further atomizes the fluid and completes the atomiza tion of the paint tails into the pattern to produce a more uniform pattern.

The

spray gun has a built-in lead and lag operation. When triggered, When flow

the gun emits air before the fluid is discharged.

the trigger is released, the fluid stops before the

stops. This helps assure

the spray is atomized and

prevents fluid buildup on the air cap. NOTE: The gun air and fluid inlets have 1/4–18 npsm

(R1/4–19) compound male threads that are compatible with

NPSM and BSP female swivel connectors.

Use the fan pattern valve (E) can be used to reduce the pattern by about 25% of the total pat tern width. As the valve is opened, the pattern will reduce slightly

This system has two air regulators. As you look at the system, the regulator (31a) on the left of the pump regulates air to the gun and the regulator (31b) on the right regulates air to the pump.

WARNING

This system has a maximum air working pressure of 100 psi (7 bar) which produces a maximum fluid working pressure of 3000 psi (210 bar). Higher pressure can cause the system to rupture or mal function and result in serious injury

With the fluid pressure set, check the pump cycle

Adjust the back pressure regulator (3) to obtain the desired circula tion rate. With the gun triggered, the cycle rate will depend on tip size, but some circulation is always desired.

Use the gun air control valve (E) to adjust the degree of atomization. Always use the lowest air pressure possible for the most ef

ficiency.

Retest the spray pattern. If there are no stripes or spots, you are ready to start spraying.

If there are stripes or spots in the spray pattern, raise the pump air pressure until you raise the fluid outlet pressure by about 100 psi (7 bar) and try again. Continue to raise the fluid pressure in 100

psi (7 bar) increments until the pattern is full and clean. Do not exceed 100 psi (7 bar) incoming air pressure or 3000 psi (210 bar) fluid working pressure.

NOTE: Always use the lowest fluid and air pres sure required for good atomization and spray pat tern for maximum fluid ef approximately 50 psi (3.3 bar) will cause turbu lence in the fan pattern, dirty air caps and slower production capability
