WARNING
Two required safety devices are supplied with your
pump: a bleed-type master air valve (8) and a
pump bleeder valve (25). These devices help
reduce the risk of serious injury, including splashing
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 valve is located close to the
pump, downstream from the pump air regulator.
The pump bleeder valve assists in relieving fluid
pressure in the displacement pump, hose, and
dispensing valve. Triggering the dispensing valve to
relieve pressure may not be sufficient.
Supplied Components
The following components are supplied with your
pump.
D
The bleed-type master air valve (8) is supplied
with your system to relieve air trapped between it
and the air motor when the valve is closed (see the
WARNING above).
D
The pump air regulator (27a) controls pump
speed and outlet pressure by adjusting the air
pressure to the pump. The regulator is located
upstream from the bleed-type master air valve.
D
The ram air regulator (27b) controls ram speed by
adjusting the air pressure to the ram, and also
controls the pressure exerted by the wiper plate on
the fluid.
D
The pump bleeder valve (25) is supplied in your
system to relieve fluid pressure in the displacement
pump, hose, and dispensing valve (see the WARN-
ING at left). Be sure the drain hole in the valve is
pointing down. This valve is also used to bleed air
from the pump when priming.
Air Line
Connect an air supply hose to the 1/4 npt(f) main air
inlet fitting (57). Install an air line filter and lubricator in
the main air line. In the main air line, upstream from all
other air line accessories, install a second bleed-type
master air valve to shut off all air to the system and to
isolate the accessories for servicing.
Fluid Line
Connect a fluid hose to the fluid outlet fitting (28).
Connect a suitable dispensing valve to the free end of
the hose.
