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 F
. 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

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.
