Installation

Grounding

Proper grounding is an essential part of maintaining a safe system.

To reduce the risk of static sparking, ground the pump. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Be sure to ground all of this equipment:

DPump: Use a ground wire and clamp as shown in Fig. 1.

DAir compressor: Follow manufacturer???s recommen- dations.

DObject being sprayed: Follow your local code.

DAll solvent pails used when flushing or relieving pressure, always hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun.

DTo maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the spray gun.

To ground the pump:

1.UL???Listed Pumps: Use a ground wire, connector,

and clamp. See Fig. 1. Loosen screw (X). Insert one exposed end of a 12 ga (1.5 mm2) minimum ground wire (Y) through the eye of the ground terminal connector (W) and tighten screw (X) securely. Connect the other end of the wire to a true earth ground. Order Part No. 237569 Ground Wire and Clamp.

2.Non UL???Listed Pumps: See Fig. 1. Remove the ground screw (Z). Fasten the ground connector

(W) onto the pump with the ground screw (Z) and

tighten securely. Loosen screw (X). Insert one exposed end of a 12 ga (1.5 mm2) minimum ground wire (Y) through the eye of the ground terminal connector (W) and tighten screw (X) securely. Connect the other end of the wire to a true earth ground. Order Part No. 222011 Ground Connector/Wire and Clamp.

Operation

Pressure Relief Procedure

WARNING

INJECTION HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid

under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

Dare instructed to relieve the pressure,

Dstop spraying/dispensing,

Dcheck or service any of the system equipment,

Dor install or clean the spray tips or nozzles.

1.Shut off the air to the pump.

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

3.Hold a metal part of the gun to the side of a grounded metal pail and trigger the gun to relieve pressure.

4.Open the fluid drain valve (required in your sys- tem), having a container ready to catch the drain- age.

5.Leave the drain valve open until you are ready to spray/dispense again.

If you suspect that the spray tip/nozzle or hose is clogged or that fluid pressure is not fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually. Clear the tip or hose obstruction.

Troubleshooting

WARNING

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

Pressure Relief Procedure on page 5.

Relieve the Pressure before you check or service any system equipment.

NOTE: Check all other possible problems and solu- tions before disassembling the pump.

Service

NOTE: Repair Kit 214584 is available. For best results, use all the new parts in the kit, even if the old parts look good. Parts included in the kit are marked with a dagger, for example (6???), in the text and illustrations.

Air Piston and Lower Spring Service

WARNING

To reduce the risk of injury from trapped air pres- sure when servicing the air motor, always remove air cap (7) from air cylinder (8) before removing air cylinder from base (22).

1.Unscrew the cylinder cap (7) from the cylinder (8). To remove the spring (5), pry gently under the coils in the direction of the helix.

2.Unscrew the cylinder (8) from the base (22) and lift the cylinder off the air piston (11). Using a pliers

(B) on the air exhaust plate (16) and a wrench (C) on the piston shaft (23), unscrew the piston from the shaft. See Fig. 2.

CAUTION

Ketone fumes may damage the piston o-rings. When pumping ketones (such as acetone, MEK, etc.), use Conversion Kit 221038. This kit replaces the stan- dard fluoroelastomer o-rings with EPDM o-rings which are resistant to ketones.

3.Disassemble the piston and wash all parts in compatible solvent. Refer to the parts list on page 9. Blow parts dry and inspect for wear or damage. If any of the valve plate spacers (13) are damaged, replace all three to maintain proper clearance between the valve plates and the seats.

4.Remove and inspect the lower spring (20). Re- place if necessary, and reinstall.

5.A decrease in performance accompanied by a slower than normal cycle rate is commonly caused by icing. It is recommended that the pump is shut down, and the ice is allowed to thaw.

6.Reassemble the air piston (11), using new parts as needed. Apply a good grade of thread sealant to the threads of the screws (12). and torque evenly to 1.1???1.6 NSm (10???14 in-lb). With the washer (4) in place, apply thread sealant to the threads of the piston. Carefully screw the piston (11) onto the shaft (23) by hand so it is securely fastened. Do not use pliers on the air exhaust plate while tight- ening. When installed, there should be 0.8 mm (0.032 in.) minimum clearance between the wash- er (4) and the piston shaft shoulder. See Fig. 2.

Packing Replacement

1.Unscrew the cylinder cap (7) from the cylinder (8). To remove the spring (5), pry gently under the coils in the direction of the helix.

2.Unscrew the cylinder (8) from the base (22) and lift the cylinder off the air piston (11). Disconnect the piston shaft (23) from the pump connecting rod and pull the shaft up out of the air motor base. Remove and inspect the packing (9???), being careful not to mar the inner lip. See Fig. 2.

NOTE: Fluoroelastomer packing 111383 is available as an accessory, for use with solvents not compatible with the standard nitrile rubber packing.

3.Replace the packing and reassemble the air motor in the reverse order of disassembly.

Upper Spring Replacement

Unscrew the cylinder cap (7) from the cylinder (8). To remove the spring (5), pry gently under the coils in the direction of the helix.

Cleaning the Muffler

To clean the muffler (26), remove it from the unit and soak it in mineral spirits, then blow dry with air to remove excess solvent.
