Supplied Components
Refer to Fig. 2.
WARNING
A red-handled bleed-type master air valve (E) and
a fluid drain valve (D) are supplied. These compo-
nents help reduce the risk of serious injury, includ-
ing fluid injection and 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. Locate the valve close to the pump.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient.
The red-handled bleed-type master air valve (E)
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 (F).
Setup
Remove the clip pins from the air line couplers
(22, 23). Screw the female coupler (23) onto the
main air hose. Leave the male coupler (22) at-
tached to the air regulator (F). Do not connect the
couplers until you are ready to operate the pump.
The air regulator (F) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. Locate close to the pump, but upstream
from the bleed-type master air valve (E).
The air relief valve (41) opens automatically to
prevent overpressurization of the pump.
The fluid filter (16) includes a 60 mesh (250
micron) stainless steel element to filter particles
from the fluid as it leaves the pump. It also includes
the fluid drain valve (D), which is required in your
system to relieve fluid pressure in the hose and gun
(see the WARNING at left).
The suction hose (25) and tube (26) allow the
pump to draw fluid from a 5 gallon (19 liter) pail (H).
The strainer at the end of the suction tube keeps
large particles from entering the pump.
