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. 2.

DAir compressor: Follow the manufacturer’s recom- mendations.

DObject being dispensed to: Follow the local code.

DFluid supply container: Follow the local code.

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

To ground the pump, remove the ground screw (Z) and insert through the eye of the ring terminal at end of ground wire (Y). Fasten the ground screw back onto the pump and tighten securely. Connect the other end of the wire to a true earth ground. To order a ground wire and clamp, order Part No. 222011.

System Accessories

WARNING

Three accessories are required in your system: bleed-type master air valve, fluid drain valve, and grounding wire. Additionally, for permanent installa- tions, a thermal relief kit is required. These acces- sories help reduce the risk of serious bodily injury, including fluid injection, splashing in the eyes or on the skin, injury from moving parts if you are adjust- ing or repairing the pump, and explosion from static sparking.

DThe bleed-type master air valve (E) relieves air trapped between it and the air motor after the air supply is shut off. Trapped air can cause the air motor to cycle unexpectedly, causing serious injury if you are adjusting or repairing the pump. As an alternative, use a quick-disconnect coupler and fitting. Install them near the pump air inlet within easy reach from the pump.

DThe fluid drain valve (N) assists in relieving fluid pressure in the displacement pump, hoses, and dispensing valve. Triggering the valve to relieve pressure may not be sufficient.

DThe ground wire (G) reduces the risk of static sparking.

DThe thermal relief kit (R) assists in relieving pressure in the pump, hose, and dispensing valve due to heat expansion.

D Extension Tubes: Pump models 222103 and

222104 have extensions tubes. An extension tube

may be added to the Universal pump for use in

submerged applications. To install, apply PTFE

tape to the female threads at the top of the tube.

Thread the tube tightly into the intake housing of

the Universal pump. Also, install a bung adapter. To

order a standard 2-in. bung adapter, order Part No.

222308.

D Air and Fluid Hose Kits (F): An 18-in. kit for wall-

mounted pumps and a 6-ft. kit for drum-mounted

pumps are available. Use a minimum 1/4-in. ID air

supply hose between the pump air inlet and the air

accessories. To order a kit with 1/4-in. air hose,

1/4-in. swivel elbow, 3/4-in. fluid hose, and 3/4-in.

swivel elbow, order one of the kits below:
