Graco 308550ZAD important safety instructions Air Line, Typical FLOOR-MOUNT Installation

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. 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 contamination from hazardous fluids. See Fig. 2.

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.Install an air regulator (C) and gauge to control the fluid pressure. The fluid outlet pressure will be the same as the setting of the air regulator.

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

c.The air line filter (F) removes harmful dirt and moisture from the compressed air supply.

2.Install an electrically conductive, flexible air hose

(A) between the accessories and the 1/2 npt(f) pump air inlet (N). See Fig. 2. Use a minimum 1/2” (13 mm) ID air hose.

3.Screw an air line quick disconnect coupler (D) onto the end of the air hose (A); be sure the coupler porting is large enough to not restrict the air flow, which will affect pump performance. Screw the mating fitting into the pump air inlet snugly. Do not connect the coupler (D) to the fitting until you are ready to operate the pump.
