Installation

Grounding

The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.

Pump: use a ground wire and clamp. Loosen the grounding lug locknut and washer. Insert one end of a

1.5 mm2 (12 ga) minimum ground wire into the slot in lug and tighten the locknut securely. Connect the other end of the wire to a true earth ground. Order Part 237569 Ground Wire and Clamp.

Installation

ti8250a

FIG. 4

Air and fluid hoses: use only electrically conductive

hoses.

Air compressor: follow manufacturer's recommendations.

Spray gun/dispense valve: ground through connection to a properly grounded fluid hose and pump.

Fluid supply container: follow your local code.

Object being sprayed: follow your local code.

Solvent pails used when flushing: follow local code.

Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.

To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray

gun/dispense valve firmly to the side of a grounded metal pail, then trigger the gun/valve.

Installation

System Accessories

A main air bleed valve and pump bleed valve (P) are required. These accessories 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 main air shutoff valve shuts off the air to the pump and ram. The air motor 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 pump bleed valve assists in relieving fluid pressure in the displacement pump, hose, and gun/valve. Triggering the gun/valve to relieve pressure may not be sufficient.

• Air line filter (V) removes harmful dirt and moisture from the compressed air supply. Also, install a drain valve at the bottom of each air line drop, to drain off moisture.

• Air regulator (G and AH) controls pump speed and outlet pressure by adjusting the air pressure to the pump. Locate the regulator close to the pump, but upstream from the bleed-type master air valve.

• Air motor valve (AJ) is required in your system to shut off the air supply to the pump (see WARNING). When closed, the valve will bleed off all air in the pump. Be sure the valve is easily accessible from the pump.

• Pump runaway valve (AK) senses when the pump is running too fast and automatically shuts off the air to the motor. A pump which runs too fast can be seriously damaged. Locate in the position shown.

• Pump bleed valve (P) is required in your system to relieve fluid pressure in hose and gun (see WARNING).

If using Check-Mate pump with Graco Supply Systems, refer to Supply Systems Operation manual for system accessory installation instructions.

For use with all other systems, use this section for accessory installation instructions.

Be sure all air lines (T) and fluid lines (S) are properly sized and pressure-rated for your system. Use only electrically conductive hoses. Fluid hoses must have spring guards on both ends.

Mounting Accessories

Mount the pump package to suit the type of installation planned. Pump dimensions are shown on page 30. Refer to Check-Mate Displacement Pump manual 312375 for mounting hole layout.

Air Line Accessories

Install the following accessories as listed. Refer to FIG. 1 to see air line accessories represented in a typical supply unit installation.

Fluid Line Accessories

Install the following accessories as listed. Refer to FIG. 2 to see fluid line accessories represented in a typical supply unit installation.

• Install a fluid shutoff valve at each gun/valve drop, to isolate the gun/valve and fluid accessories for servicing.

• Install a fluid drain valve near the pump fluid outlet, and at each gun/valve station. The drain valves are required in your system to relieve fluid pressure in the displacement pump, hose and gun/valve (see WARNING). Drain valves at the gun/valve stations may be mounted in the base of a fluid regulator, using an adapter.

• Fluid regulator controls fluid pressure to the gun/valve, and dampens pressure surges.

• Gun or dispense valve dispenses the fluid.

• Gun/valve swivel allows freer gun/valve movement.

• Main air shutoff valve (W) isolates the air line accessories for servicing. Locate upstream from all other air line accessories.

Setup

Wet Cup

Before starting, fill the wet cup (R) 1/3 full with Graco Throat Seal Liquid (TSL) or compatible solvent.

The enclosed wet cup has a fill port in the cover.

Torque Wet Cup

The wet cup is torqued at the factory; however, throat packing seals on Severe Duty pumps may relax over time. Check wet cup torque frequently after initial start-up and periodically after the first week of production. Maintaining proper wet cup torque is important to

extending seal life.

MaxLife pumps use a special u-cup throat seal that is non-adjustable and does not require periodic torquing.

To torque the wet cup, use the following steps.

1. Follow Pressure Relief Procedure on page 12.

2. Use the packing nut wrench (supplied) to torque the wet cup; see the following table for torque values. Do this whenever necessary. Do not overtighten the wet cup.
