Installation

Air Line

1.

Install the air line accessories as shown in F

these accessories on the wall or on a bracket. Be sure
the air line supplying the accessories 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 F

. 2. Use a minimum 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.

_______________________________________________________________________

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 F
