Installation

Grounding

The equipment must be grounded to reduce the risk of static sparking. Static sparking can cause fumes to ignite or explode. Grounding provides an escape wire for the electric current.

Pump: use ground wire and clamp (supplied). Loosen grounding lug locknut (LL) and washer (LW). Insert one

end of a 1.5 mm2 (12 ga) minimum ground wire end (GW) into lug (LS) slot and tighten locknut securely. Connect ground clamp to a true earth ground. Order part 237569 ground wire and clamp.

Object being sprayed: follow 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.

Accessories

Install the following accessories in the order shown in FIG. 1, page 7, using adapters as necessary. Contact your Graco representative or Graco Technical Assistance for assistance in designing a system to suit your needs.

Air and Fluid Hoses

Air and fluid hoses: use only electrically conductive

hoses. Check electrical resistance of hoses. If total resistance to ground exceeds 29 megaohms, replace hose immediately.

Air compressor: follow manufacturer’s recommendations.

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

Fluid supply container: follow local code.

Be sure all air hoses (H) and fluid hoses (N and P) are properly sized and pressure-rated for your system. Use only electrically conductive hoses. Fluid hoses must have spring guards on both ends. Use a whip hose (P) and a swivel (R) between the main fluid hose (N) and the gun (S) to allow freer gun movement

Mounting Accessories

Mount the pump (A) to suit the type of installation planned. FIG. 1, page 7, illustrates a wall mount system. See Dimensions and Mounting Hole Layout, page 23.

If you are using a floor stand, refer to its separate manual for installation and operation instructions.

308360D 5

Installation

Air Line

• Air line lubricator (D): provides automatic air

motor lubrication.

• Bleed-type master air valve (E): required in your

system to relieve air trapped between it and the air motor when the valve is closed.

NOTE: Be sure the valve is easily accessible from the pump and located downstream from the air regulator.

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.

• Air regulator (F): controls pump speed and outlet

pressure by adjusting the air pressure to the pump.

NOTE: Locate the regulator close to the pump, but upstream from the bleed-type master air valve.

• Pump runaway valve (C): 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.

• Air manifold (G): has a 3/4 npsm(f) swivel air inlet.

It mounts to the pump support bracket, and provides ports for connecting lines to air-powered accessories.

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

• Second bleed-type air valve (K): isolates the air line accessories for servicing.

Fluid Line

• Fluid filter (L): with a 60 mesh (250 micron)

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

• Fluid drain valve (M): required in your system, to

relieve fluid pressure in the hose and gun.

• Gun (S): to dispense fluid.

NOTE: The gun shown in FIG. 1, page 7, is an airless spray gun for light to medium viscosity fluids.

• Fluid line swivel (R): for easier gun movement.

• Suction kit (T): enables the pump to draw fluid from

a container.

NOTICE

To prevent intake valve damage, always apply PTFE tape to the female threads of the intake valve before connecting a suction hose or fitting to the intake.

Flush Before Using Equipment

The equipment was tested with lightweight oil, which is left in the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the equipment with a compatible solvent before using the equipment. See Flush the Equipment, page 8.

NOTE: Locate upstream from all other air line accessories.

Torque to

136-149 N•m (100-110 ft-lb)

6. Cycle the pump slowly until all air is pushed out and the pump and hoses are fully primed.

7. Release the gun trigger, engage the trigger safety lock. The pump should stall against pressure.

8. If the pump fails to prime properly, open the drain

110

valve (M). Use the drain valve as a priming valve until the fluid flows from the valve. Close the valve.

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

NOTICE

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

04143

and prime the pump and the lines, or flush and leave it filled with a compatible solvent. Eliminate all air from the fluid system.

9. With the pump and lines primed, and with adequate air pressure and volume supplied, the pump will start and stop as you open and close the gun. In a

308360D 9

Operation

circulating system, the pump will speed up or slow down on demand, until the air supply is shut off.

10. Use the air regulator (F) to control pump speed and fluid pressure.

NOTICE

Always use the lowest air pressure necessary to get the desired results. Higher pressures cause premature tip and pump wear.

Shutdown and Care for the Pump

1. Follow the Pressure Relief Procedure, page 8.

2. Follow Flush the Equipment, page 8.

NOTICE

Always flush the pump before the fluid dries on the displacement rod and causes damage.

NOTICE

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.

10 308360D

Troubleshooting

1. Follow Pressure Relief Procedure, page 8, before

checking or repairing the pump.

Troubleshooting

To determine if the fluid hose or gun is obstructed:

1. Perform the Pressure Relief Procedure, page 8.

2. Disconnect the fluid hose and place a container at the pump fluid outlet to catch any fluid.

3. Turn on the air just enough to start the pump. If the pump starts when the air is turned on, the obstruction is in the fluid hose or gun.

2. Check all possible problems and causes before disassembling pump.
