Installation

Air Line

WARNING

A bleed-type master air valve (B) is required in your system to relieve air trapped between this valve and the pump. See Fig. 2. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury, including splashing in the eyes or on the skin, injury from moving parts, or contamina- tion from hazardous fluids.

1.Install the air line accessories as shown in Fig. 2. Mount these accessories on the wall or on a bracket. Be sure the air line supplying the acces- sories is electrically conductive.

a.The fluid pressure can be controlled in two ways, either by controlling the air into the pump with the air regulator (F) or the fluid out of the pump with the fluid regulator (H).

b.Locate a bleed-type master air valve (B) close to the pump, to relieve trapped air. See the WARNING at left. Locate another air valve (E) upstream from all air line accessories, to isolate them during cleaning and repair.

c.Install an air line filter (D) to remove harmful contaminants such as dirt, moisture, and oil from the compressed air supply.

2.The air valve does not require lubrication.

3.Install an electrically conductive, flexible air hose

(C) between the accessories and the pump air inlet

(T). Use a minimum 1/4” (6.3 mm) ID air hose. Screw an air line quick disconnect coupler (V) onto the end of the air hose and screw the mating fitting into the pump air inlet snugly. Do not connect the coupler to the fitting yet.
