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 accesso-
ries is grounded.
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 a grounded, flexible air hose (A) between the
accessories and the 1/2 npt(f) pump air inlet (N).
See Fig. 2. Use a minimum 3/8" (10 mm) ID air
hose. Screw an air line quick disconnect coupler (D)
onto the end of the air hose (A), and 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.
