Setup

WARNING

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

Pressure Relief Procedure on page 10.

Site Preparation

Fig. 1. Relieve system pressure. For installing any one of the packages listed in this manual, select a site with at least 5 ft (1.5 m) overhead clearance for the wall mounted systems and at least 7 ft (2.1 m) for the floor mounted systems.

Ensure that the wall is strong enough to support the weight of the circulation package and accessories, fluid, hoses, and stress caused during pump operation.

D The bleed-type master air valve (K) is required in

your system to relieve air trapped between it and the air motor when the valve is closed (see the preceding WARNING).

D The fluid drain valve (F), is mounted on the

bottom of the fluid filter bowl. The fluid drain valve is required in your system to relieve fluid pressure in the displacement pump, fluid filter, hose, and gun. (see the preceding WARNING).

D The pump air filter (H) includes an air filter with a

40 micron polypropylene element, to remove harmful dirt and moisture from the compressed air supply.

Ensure that you have an adequate compressed air supply.

Bring an air supply line from the facility air supply (Z) to the circulation package location. Be sure all air lines are properly sized and pressure-rated for the system. Use only electrically conductive hoses. The air hose should have a 1/2 npt(m) thread.

Install a bleed-type shutoff valve (W) in the air line to isolate the air line components for servicing. Install a moisture trap and drain valve (Y) to help remove moisture and contaminants from the compressed air supply.

Keep the site clear of any obstacles or debris that could interfere with the operator’s movement.

Have a grounded, metal pail available for use when flushing the system.

Supplied Components

Refer to Fig. 1.

WARNING

A bleed-type master air valve (K) and a fluid drain valve (F) 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.

D The pump air regulator and gauge (L) controls

pump speed and outlet pressure by adjusting the air pressure to the pump. The gauge provides a readout of air pressure to the pump. See manual 308168 for further details.

D The pump runaway control valve (M) protects

the pump against damage by a runaway air motor. See manual 308201 for further details.

D The air line lubricator (S) provides automatic

lubrication of the air motor.

D The pump (N), run by air motor, circulates fluid

throughout the system. See pump manual for further details.

D Fluid is supplied to the pump through the fluid

outlet (A). Fluid pressure is monitored by the two fluid gauges (B).

D The fluid filter (D) includes a 60 mesh (250 mi-

cron) stainless steel element to filter particles from the fluid as it leaves the pump.

D The fluid surge tank (J) protects against surges in

the fluid lines during gun use and system operation.

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.

The fluid drain valve assists in relieving fluid pressure in the displacement pump, fluid filter, hose, and gun. Triggering the gun to relieve pressure may not be sufficient.

6 310566

D The fluid regulator and gauge (V) controls fluid

inlet pressure. The gauge provides a readout of fluid pressure at the inlet. See manual 307107 for further details.

D Fluid is returned from the circulation package to the

the system through the fluid return valve (U). See valve manual 307628 for further details.

Operation

Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Proce- dure whenever you:

D are instructed to relieve the pressure, D stop spraying, D check or service any of the system equipment, D or install or clean the spray nozzle.

1. Fig. 4. Relieve the pressure of the entire system following applicable system pressure relief procedures. Ensure that system pressure is relieved before proceeding with step 2.

2. Close the bleed-type master air valve (W, required in your system).

If you suspect that pressure is not fully relieved after following the steps above, wrap a fitting near the pump outlet with a rag, and slowly and carefully loosen the fitting to relieve pressure. Be careful to protect your eyes from splashing.

Packing Nut

Fig. 4. Before starting, fill the packing nut (AA) 1/3 full with Graco Throat Seal Liquid (TSL) or compatible solvent.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure at left.

The packing nut is torqued at the factory and is ready for operation. If it becomes loose and there is leaking from the throat packings, relieve pressure, then torque the nut to 34–40 NSm (25–30 ft-lb). Do this whenever necessary. Do not overtighten the packing nut.

3. Trigger the gun at the last gun station to relieve fluid pressure. Maintain firm metal-to-metal contact between the gun and a grounded waste pail. Repeat for all gun stations.

4. Open the fluid drain valve (14) to relieve fluid pressure which may be trapped in the pump, plumbing, or hose.

Flush the Circulation Package Before First Use

The circulation package is tested with lightweight oil, which is left in to protect the circulation package parts. If the fluid you are using may be contaminated by the oil, flush it out with a compatible solvent. See Flush- ing on page 13.
