Setup
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
Site Preparation
Fig. 1. Relieve system pressure. For installing any
one of the packages listed in this manual, select a site
with at least 5 ft (1.5 m) overhead clearance for the
wall mounted systems and at least 7 ft (2.1 m) for the
floor mounted systems.
Ensure that the wall is strong enough to support the
weight of the circulation package and accessories,
fluid, hoses, and stress caused during pump operation.
Ensure that you have an adequate compressed air
supply.
Bring an air supply line from the facility air supply (Z) to
the circulation package location. Be sure all air lines
are properly sized and pressure-rated for the system.
Use only electrically conductive hoses. The air hose
should have a 1/2 npt(m) thread.
Install a bleed-type shutoff valve (W) in the air line to
isolate the air line components for servicing. Install a
moisture trap and drain valve (Y) to help remove
moisture and contaminants from the compressed air
supply.
Keep the site clear of any obstacles or debris that
could interfere with the operator’s movement.
Have a grounded, metal pail available for use when
flushing the system.
Supplied Components
Refer to Fig. 1.
WARNING
A bleed-type master air valve (K) and a fluid drain
valve (F) are supplied. These components help
reduce the risk of serious injury, including splashing
of fluid in the eyes or on the skin, and injury from
moving parts if you are adjusting or repairing the
pump.
The bleed-type master air valve relieves air trapped
between this valve and the pump after the air is
shut off. Trapped air can cause the pump to cycle
unexpectedly.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, fluid filter, hose,
and gun. Triggering the gun to relieve pressure
may not be sufficient.
D The bleed-type master air valve (K) is required in
your system to relieve air trapped between it and
the air motor when the valve is closed (see the
preceding WARNING).
D The fluid drain valve (F), is mounted on the
bottom of the fluid filter bowl. The fluid drain valve
is required in your system to relieve fluid pressure
in the displacement pump, fluid filter, hose, and
gun. (see the preceding WARNING).
D The pump air filter (H) includes an air filter with a
40 micron polypropylene element, to remove harm-
ful dirt and moisture from the compressed air
supply.
D The pump air regulator and gauge (L) controls
pump speed and outlet pressure by adjusting the
air pressure to the pump. The gauge provides a
readout of air pressure to the pump. See manual
308168 for further details.
D The pump runaway control valve (M) protects
the pump against damage by a runaway air motor.
See manual 308201 for further details.
D The air line lubricator (S) provides automatic
lubrication of the air motor.
D The pump (N), run by air motor, circulates fluid
throughout the system. See pump manual for
further details.
D Fluid is supplied to the pump through the fluid
outlet (A). Fluid pressure is monitored by the two
fluid gauges (B).
D The fluid filter (D) includes a 60 mesh (250 mi-
cron) stainless steel element to filter particles from
the fluid as it leaves the pump.
D The fluid surge tank (J) protects against surges in
the fluid lines during gun use and system operation.
D The fluid regulator and gauge (V) controls fluid
inlet pressure. The gauge provides a readout of
fluid pressure at the inlet. See manual 307107 for
further details.
D Fluid is returned from the circulation package to the
the system through the fluid return valve (U). See
valve manual 307628 for further details.
