•
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
recommendations.
•
All solvent pails used when flushing: Follow the local
code. Use only metal pails, which are conductive. Do
not place the pail on a non-conductive surface, such
as paper or cardboard, which interrupts the
grounding continuity.
•
Fluid supply container: Follow the local code.
Mountings
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 10.
1. Be sure the mounting surface can support the weight

2. For all mountings, be sure the pump is bolted directly
to the mounting surface.
3. 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.
4. Rubber Foot Mounting Kit 236452 is available to
reduce noise and vibration during operation.
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 F . 2.
IG
1. Install the air line accessories as shown in F
Mount these accessories on the wall or on a bracket.
Be sure the air line supplying the accessories 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 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.
2. Install a grounded, flexible air hose (A) between the
accessories and the 1/2 npt(f) pump air inlet (N). See
F . 3. Use a minimum 1/2 in. (13 mm) ID air hose.
IG
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.
