• Air and fluid hoses: Use only grounded hoses with a
maximum of 500 ft (150 m) combined hose length to
ensure grounding continuity.
• Air compressor: Follow the manufacturer’s recom-
mendations.
• Fluid supply container: Follow the local code.
Mountings
• Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as well
as the stress caused during operation.
• For ease of operation and service, mount the pump
so the air valve cover (2), air inlet, and fluid inlet and
outlet ports are easily accessible.
Air Line
1. Install the air line accessories as shown in FIG. 3.
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. 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 (M).
Use a minimum 3/8 in. (9.5 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.
Fluid Suction Line
1. Use flexible, grounded fluid hoses (G) where possi-
ble.
2. For best sealing results, use a standard Tri-Clamp®
style sanitary gasket of a flexible material such as
EPDM, Buna-N, fluoroelastomer, or silicon.
3. If the fluid inlet pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in ineffi-
cient pump operation.
CAUTION
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. See Air Exhaust Ventilation
on page 8.
A bleed-type master air valve (B) is required in the
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
IG. 3.

Ground Wire Connection
TI4736A
Do not connect the coupler (D) to the fitting until you
are ready to operate the pump. Connecting the cou-
pler too early can result in unintentional operation of
the pump, leading to serious injury from to moving
parts, splashing fluid in the eyes or on the skin, and
contact with hazardous fluids.
