1.Install the pump on the drum cover so that the pump’s fluid intake is 1/2 inch. (13 mm) off the bot- tom of the drum. (FIG. 2)

2.On Models 204254 and 222087, screw the bung adapter tightly into the drum cover’s bung hole, adjust the position of the pump in the drum, and tighten the bung adapter screw to hold the pump,

System Accessories

Refer to FIG. 2 for the following instructions.

Four accessories are required in your system: an air shut-off valve/air bleed device, fluid drain valve, thermal relief kit, and ground wire. These accessories help reduce the risk of serious bodily injury, including fluid injection, splashing in the yes or on the skin, injury from moving parts if you are adjusting or repair the pump, and explosion from static sparking.

The air bleed device relieves air trapped between it and air motor after the air supply is shut off. Trapped air can cause the motor to cycle unexpectedly, causing serious injury if you are adjusting or repairing the pump. Use either a bleed-type master air valve (A) or a quick-disconnect coupler (M) and fitting (L). Install them near the pump air inlet within easy reach from the pump.

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

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

The ground wire (F) reduces the risk of static sparking.

NOTICE

Do not hang the air accessories directly on the air inlet (E). The fittings are not strong enough to support the accessories and may break. Provide a bracket on which to mount the accessories.

NOTE: Install the air line accessories in the order shown in FIG. 2.

Installation

1.Install a pump runaway valve (D) to shut off the air to the pump if the pump accelerates beyond the pre-adjusted setting. A pump that runs too fast can be seriously damaged.

NOTICE

Never allow the pump to run dry of fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself, and it may get very hot.

2.Install an air line lubricator (N) for automatic air motor lubrication.

3.Install a bleed-type master air valve (A) to relieve air trapped between the valve and the motor. As an alternative, you can install an air line quick-discon- nect coupler (M) and fitting (L) to serve as an air-bleed device. See FIG. 2.

4.Install a Thermal Relief Kit (K) on the dispensing valve side of the pump.

5.Install the air regulator (C) to control pump speed and pressure.

6.Install an air line filter (B) to remove harmful dirt and contaminants from the compressed air supply. Install another bleed-type master air valve (A) to iso- late the accessories for servicing.

7.Install a drain valve (H) near the pump fluid outlet.

8.Install a suitable fluid hose (P) and dispensing valve

(J).
