4 308360D

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.

Operation

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

1. Engage trigger lock.

2. Shut off the air supply to the pump.

3. Close the bleed-type master air valve.

4. Disengage the trigger lock.

5. Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to relieve pressure.

Flush the Equipment

To avoid fire and explosion, always ground equipment and waste container. To avoid static sparking and injury from splashing, always flush at the lowest possible pressure.

• Flush before fluid can dry in the equipment, at the end of the day, before storing, and before repairing equipment.

• Flush at the lowest pressure possible. Check connectors for leaks and tighten as necessary.

• Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts.

1. Perform Pressure Relief Procedure, page 8.

2. Remove spray tip from the gun.

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

4. Start the pump.

5. Trigger the gun until clean solvent dispenses.

6. Engage the trigger lock.

7. Open all fluid drain valves in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to spray again.

8. If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved:

a. VERY SLOWLY loosen the tip guard retaining

nut or the hose end coupling to relieve pressure gradually.

b. Loosen the nut or the coupling completely.

c. Clear the obstruction in the hose or tip.
