Supplied Components

Refer to Fig. 3.

WARNING

A red-handled bleed-type master air valve (E) and a fluid drain valve (D) are supplied. These components help reduce the risk of serious injury, including fluid injection and splashing of fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.

The bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump.

The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun.

Triggering the gun to relieve pressure may not be sufficient.

D The red-handled bleed-type master air valve (E) is required in your system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING above). Be sure the bleed valve is easily accessible from the pump, and is located downstream from the pump air regulator

(F).

Setup

D The pump air regulator (F) controls pump speed and outlet pressure by adjusting the air pressure to the pump. Locate close to the pump, but upstream from the bleed-type master air valve (E).

D The air relief valve (41) opens automatically to prevent overpressurization of the pump.

D The gun air filter/regulator (G) adjusts the air pressure to the electrostatic air-assisted airless spray gun (106).

D The air manifold (H) directs incoming air to the pump and to the gun. It includes an air inlet swivel fitting.

D The fluid filter (16) includes a 60 mesh (250 micron) stainless steel element to filter particles from the fluid as it leaves the pump. It also includes the fluid drain valve (D), which is required in your system to relieve fluid pressure in the hose and gun

(see the WARNING at left).

D The suction hose (25) and tube (26) allow the pump to draw fluid from a 5 gallon (19 liter) pail (K).

The strainer at the end of the suction tube keeps large particles from entering the pump.

D The back pressure regulator (40) controls back pressure to the gun and maintains proper circulation pressure.

D The 3-way valve (45) allows you to circulate fluid back to the pump or return it to the fluid container.

FIRE AND EXPLOSION HAZARD

Do not plug in or unplug the power cord in any area containing flammable fluids or fumes, to avoid fire or explosion resulting in serious injury.

1.

Start the pump. Plug in the heater power cord.

Turn the 3-way valve (45) to CIRC.

CAUTION

Do not allow the pump to run dry. It will quickly accelerate to a high speed, causing damage. If your pump is running too fast, stop it immediately and check the fluid supply. If the container is empty and air has been pumped into the lines, refill the container and prime the pump and the lines, or flush and leave it filled with a compatible solvent. Eliminate all air from the fluid system.

2.

Set the heater control to a trial point (4 or 5).

3.

Circulate fluid through the pump for at least 10 minutes, at very low pressure. Check the temperature on the heater thermometer.

4.

Adjust the fluid pressure and temperature to the lowest settings necessary to get the desired results. Use the air regulator (F) to adjust the pump speed and fluid pressure until the spray is completely atomized. Refer to the back pressure valve and heater manuals (supplied) for adjustment procedures. Higher pressures and temperatures may not improve the spray pattern and will cause premature component wear.

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 11.

For overnight shutdown, stop the pump at the bottom of its stroke to prevent fluid from drying on the exposed displacement rod and damaging the throat packings. Relieve the pressure.

Always flush the pump before the fluid dries on the displacement rod. See Flushing on page 17.

Flushing

Operation

WARNING

FIRE AND EXPLOSION HAZARD

Before flushing, read the section FIRE

OR EXPLOSION HAZARD on page 5.

Be sure the entire system and flushing pails are properly grounded. Refer to

Grounding on page 6.

Flush the pump:

D

Before the first use

D When changing colors or fluids

D Before fluid can dry or settle out in a dormant pump

(check the pot life of catalyzed fluids)

D

Before storing the pump.

Flush with a fluid that is compatible with the fluid you are pumping and with the wetted parts in your system.

Check with your fluid manufacturer or supplier for recommended flushing fluids and flushing frequency.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 11.

WARNING

HOT SURFACE HAZARD

Do not touch the heater while it is operating. Allow the heater to cool for at least

10 minutes before flushing or servicing it.

WARNING

FIRE AND EXPLOSION HAZARD

Do not plug in or unplug the power cord in any area containing flammable fluids or fumes, to avoid fire or explosion resulting in serious injury.

1.

Unplug the heater power cord and circulate the fluid for at least 10 minutes to cool the heated fluid and the heater.

2.

Relieve the pressure. Be sure to turn the gun’s ES

ON-OFF lever to the OFF position.

3.

Remove the tip guard and spray tip from the gun.

See the gun manual.

4.

Remove the filter element from the fluid filter (16).

Reinstall the filter bowl.

5.

Open the back pressure regulator (40). Set the

3-way valve (45) to CIRC.

6.

Place the suction tube (26) in a container of solvent.

7.

Point the gun down into a grounded metal pail.

8.

Start the pump. Always use the lowest possible fluid pressure when flushing.

9.

Trigger the gun. Flush the system until clear solvent flows from the gun.

10. Release the gun trigger and lock the trigger safety.

The pump will continue to cycle as long as air is supplied and the back pressure regulator is open.

11. Set the 3-way valve (45) to DRAIN. Hook the drain hose (46) onto a waste container and continue flushing until clear fluid comes from the hose.

12. Relieve the pressure.

13. Clean the tip guard, spray tip, and fluid filter element separately, then reinstall them.

14. Clean the inside and outside of the suction tube

(26).

This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written recommendations.

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.
