Air Line
1. Install the air line accessories as shown in FIG.3.
Mount these accessories on the wall or on a
bracket. Be sure the air line supplying the accesso-
ries is grounded.
a. Install an air regulator (C) and gauge to control
the fluid pressure. The fluid outlet pressure will
be three times the setting of the air regulator.
b. A bleed-type master air valve (B) is required in
your system to relieve air trapped between it
andthe pump when the valve is closed. Trapped
air can cause the pump to cycle unexpectedly
which could result in serious injury including
splashing in the eyes or on the skin, or injury
from moving parts. Be sure the bleed valve is
easily accessible from the pump, and is located
downstream from the air regulator.
c. The air line filter (D) removes harmful dirt and
moisture from the compressed air supply.
d. Asecond bleed-type air valve (T) isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
2. Install a grounded, flexible air hose (A) between the
accessories and the pump air inlet. See Technical
Data on page 25 to determine the air inlet size of
your pump. Use a minimum 13 mm (1/2 in.) ID air
hose.
3. Screw an air line quick disconnect coupler (N) onto
the end of the air hose (A), and screw the mating fit-
ting into the pump air inlet snugly. Do not connect
the coupler to the fitting until you are ready to oper-
ate the pump.
Fluid Suction Line
• Use conductive hoses (E). See FIG.3.
• See Technical Data on page 25 to determine the
fluid inlet size of your pump.
• For maximum suction lift (wet and dry) information,
see Technical Data on page 25.
Fluid Outlet Line
1. Use conductive fluid hoses (J). See FIG.3.See
Technical Data on page 25 to determine the fluid
outlet size of your pump.
2. Install a fluid drain valve (G) near the fluid outlet.
The fluid drain valve is required to relieve pressure
in the hose and gun. The drain valve reduces the
riskof serious injury, including splashing in the eyes
or on the skin, or injury from toxic fluids.
3. Install a shutoff valve (H) in the fluid outlet line.
