Installation
System Accessories
Refer to Fig. 2 and the Accessories section.
NOTE:
To ensure maximum pump performance, be
sure that all accessories used are properly sized to
meet your system’s requirements.
WARNING
A bleed-type master air valve (D) and a fluid drain
valve
(E) are required in your system, to help re-
duce the risk of serious injury, including splashing
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
(D) relieves air
trapped between this valve and the pump after the
pump is shut off. Trapped air can cause the pump
to cycle unexpectedly and result in serious injury,
including amputation. Locate the valve close to the
pump.
The
fluid drain valve
(E) helps relieve pressure in
the displacement pump, hose, and dispensing
valve when shutting off the pump. Actuating the
dispensing valve to relieve pressure may not be
sufficient, especially if there is a clog in the hose or
the dispensing valve.
Air Line Accessories
Install the following accessories in the order shown in
the Typical Installation, using adapters as necessary:
D
An
air line lubricator (B)
provides automatic air
motor lubrication.
D
A bleed-type master air valve (D)
is required in
your system to relieve air trapped between it and
the air motor when the valve is closed (see the
WARNING
above). Be sure the bleed valve is
easily accessible from the pump, and is located
downstream
from the air regulator.
D
An
air regulator (A)
controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. Locate the regulator close to the pump, but
upstream
from the bleed-type master air valve.
D
An
air line filter (C)
removes harmful dirt and
moisture from the compressed air supply.
D
A second
bleed-type air valve (D)
isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
Fluid Line Accessories
A fluid drain valve (E)
is required in your system to
relieve fluid pressure in the hose and gun (see the
WARNING
at left). Install the drain valve pointing
down, but so the handle points up when the valve is
opened.
CONNECT THE HOSES
Connect a grounded air supply hose (G) to supply air
to the pump’s 1/4 npt(f) air inlet (K). Connect a
grounded fluid hose (H) to the 1/2 npt(f) fluid outlet
(M). In a circulating system, remove the pipe plug and
connect a fluid return line to the 3/8 npt(f) return port
(F). See Fig. 3 and the Typical Installation drawing,
Fig. 2.
To use Model 223954 in a fixed mounting, connect a
supply line to the 3/4 npt fluid inlet (J).
