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 contamination from hazardous
fluids.
CAUTION
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. Read Air Exhaust Ventilation
on page 6.
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 accessories is
electrically conductive.
a. The fluid pressure can be controlled in either of
two ways. To control it on the air side, install an
air regulator (G). To control it on the fluid side,
install a fluid regulator (J) near the pump fluid
outlet (see Fig. 2).
b. Locate one bleed-type master air valve (B) close
to the pump and use it to relieve trapped air.
Read the WARNING above. 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.
Installation
2. Install an electrically conductive, flexible air hose (C)
between the accessories and the 1/4 npt(f) pump air
inlet. Use a minimum 1/4 in. (6.3 mm) ID air hose.
Screw an air line quick disconnect coupler (D) onto
the end of the air hose (C), and screw the mating
fitting into the pump air inlet snugly. Do not connect
the coupler (D) to the fitting yet.
Fluid Suction Line
•
If using a conductive (acetal) pump, use conductive
hoses. If using a non-conductive pump, ground the
fluid system. Read Grounding on page 8. The fluid
inlet port is 3/4 in.
•
At inlet fluid pressures greater than 15 psi (0.1 MPa, 1
bar), diaphragm life will be shortened.
Fluid Outlet Line
A fluid drain valve (H) is required in your system to
relieve pressure in the hose if it is plugged. See Fig. 2.
The drain valve reduces the risk of serious injury,
including splashing in the eyes or on the skin, or
contamination from hazardous fluids when relieving
pressure. Install the valve close to the pump fluid outlet.
1. Use electrically conductive fluid hoses (K). The pump
fluid outlet is 3/4 in. Screw the fluid fitting into the
pump outlet snugly. Do not overtighten.
2. Install a fluid regulator (J) at the pump fluid outlet to
control fluid pressure, if desired (see Fig. 2). See Air
Line, step 1a, for another method of controlling
pressure.
3. Install a fluid drain valve (H) near the fluid outlet.
