Supplied Components

Refer to Fig. 1.

WARNING

A red-handled bleed-type master air valve (11h) and a fluid drain valve (208) are supplied. These components help reduce the risk of serious injury, including 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

(11h) 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 filter/regulator (11a).

D The pump air filter/regulator (11a) controls pump speed and outlet pressure by adjusting the air pressure to the pump. It includes an air filter with a

40 micron polypropylene element, to remove harmful dirt and moisture from the compressed air supply. Locate close to the pump, but upstream from the bleed-type master air valve (11h).

D The air line lubricator (11b) provides automatic lubrication of the air motor.

D The air relief valve (11j) opens automatically to prevent overpressurization of the pump.

D Fluid is supplied to the pump through the suction

hose (16) and tube (109). The suction tube (109) is installed in the shaft of the agitator (102). See

Fig. 1.

D The fluid filter (206) includes a 60 mesh (250 micron) stainless steel element to filter particles from the fluid as it leaves the pump.

D The fluid drain valve (208), is mounted in the bottom of the fluid filter bowl, and is required in your system to relieve fluid pressure in the hose and gun

(see the WARNING at left).

D The back pressure regulator (12) controls back pressure to the gun and maintains proper circulation pressure.

D The back-geared agitator (102) keeps the fluid in suspension and also includes a suction tube (109) to draw fluid from a 55 gallon drum.

D The air-operated elevator (150) allows you to raise the drum cover and agitator from an empty drum, replace the drum, and lower the agitator into the new drum.

4.

Adjust the fluid pressure and temperature to the lowest settings necessary to get the desired results. Use the air filter/regulator (11a) and the back pressure regulator (12) 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.

5.

To adjust the spray pattern, follow the complete instructions in your gun manual.

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing your system, which could cause component rupture and serious injury,

never exceed the specified maximum air input

pressure to the package (see Technical Data on page 25).

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.

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing your package, which could cause component rupture and serious injury, never

exceed 100 psi (0.7 MPa, 7 bar) air input pressure

to the package. Also refer to the Technical Data section on page 25 and to your separate component manuals.

Heat causes fluid to expand. If the heated fluid is trapped with nowhere to expand, it can cause component rupture.

Close the agitator’s needle valve (L).

2.

Connect the quick coupler (124) on the end of the coiled hose (105) to the male fitting (M) on the agitator (102).

2.

Shut off the agitator (102).

3.

Relieve the pressure.

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 18.

NOTE: When changing fluid containers with the hose and gun already primed, open the drain valve (208) to help prime the pump and vent air before it enters the hose. Close the drain valve when all air is eliminated.

Preventive Maintenance Schedule

The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system.

Flushing

5.

Lower the agitator (102) into a container of solvent.

Start the agitator and run it slowly.

6.

Hold a metal part of the gun firmly to the side of a grounded metal pail.

7.

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

8.

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

WARNING

FIRE, EXPLOSION, AND

ELECTRIC SHOCK HAZARD

Before operating the pump, ground the system as explained below. Also read the section FIRE, EXPLOSION, AND

ELECTRIC SHOCK HAZARD on page

4.

9.

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 (12) is open.

10. Direct the drain hose (42) into a waste container.

Set the 3-way recirculation valve (19) to the drain position. Continue flushing until clear fluid comes from the hose.

11. Relieve the pressure.

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.

12. Clean the air cap, spray tip, and fluid filter element separately, then reinstall them.

Air Filter Service

Repair Kits are available. Refer to page 19.

Every day, drain contaminants from the bowl before reaching the baffle level by opening the drain (P) at the bottom of the bowl (N).

WARNING

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

Pressure Relief Procedure on page 14.

WARNING

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

Pressure Relief Procedure on page 14.

1.

Relieve the pressure.

2.

Remove the air cap and spray tip from the gun.

See the gun manual.

3.

Remove the filter element from the fluid filter (206).

Reinstall the filter bowl.

4.

Open the back pressure regulator (12). Set the

3-way recirculation valve (19) to the circulation position.

18 308770

Clean the air filter regularly to maximize filtering efficiency and to avoid excessive pressure drop. Fully relieve pressure to remove the bowl (N).

Clean the filter element (311) and bowl using household soap and water or denatured alcohol. Use compressed air to blow out the filter body. Blow the filter element out from the inside.

Clean the sight glass (309) thoroughly. Do not leave solvent residue in the sight glass as it may attack or weaken the glass. If the sight glass appears damaged, replace it immediately.
