Installation

System Accessories

Refer to Fig. 2 and the Accessories section.

NOTE: To ensure maximum pump performance, be sure that all accessories used are properly sized to meet your system’s requirements.

Most models are supplied with a needle-type air con- trol valve (K) at the pump air inlet. Model 226951 is equipped with an air regulator kit (CC) instead (see Fig. 3). All models are supplied with an air line quick disconnect coupler (L) to connect the air line to the pump and accessories.

Model 226951 Only

Using moderate force, extend the pump suction tube, insert the pump into the drum or tank bung hole, and screw the bung adapter (B) tightly into the bung hole. Lift the pump about 13 mm (0.5 in.) and tighten the bung adapter (B) screw to hold the pump. Loosen the vent plug (A). Refer to Fig. 2.

CAUTION

To prevent damaging the o-ring seals inside the suc- tion tube, do not use excessive force when extending the suction tube.

WARNING

A bleed-type master air valve (D) and a fluid drain valve (G) are required in your system, to help re- duce the risk of serious injury, including splashing fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.

The bleed-type master air valve (D) relieves air trapped between this valve and the pump after the pump is shut off. Trapped air can cause the pump to cycle unexpectedly and result in serious injury, including amputation. Locate the valve close to the pump.

The fluid drain valve (G) helps relieve pressure in the displacement pump, hose, and dispensing valve when shutting off the pump. Actuating the dispensing valve to relieve pressure may not be sufficient, especially if there is a clog in the hose or the dispensing valve.

For automatic air motor lubrication, install an air line lubricator (C) downstream from the air regulator (if supplied) and all other accessories. Install a bleed-type master air valve (D) close to the pump. Next, install the air regulator (CC), if supplied. Install an air line filter (E) upstream from all other accessories, to remove harm- ful dirt and moisture from the compressed air supply.

Using a suitable adapter, install the male disconnect pin fitting (J) in the air filter inlet. Install the air line quick disconnect coupler (L) on the air hose (F), but do not connect it to the pin fitting yet.

Connect an electrically conductive fluid hose (M) to the 3/4 npt(f) fluid outlet.
