Installation
NOTE:
Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawings.
Mounting the Pump
Mount the pump to suit the type of installation planned.
See the
Installation
drawings on page 5. Also refer
to the
Dimensions
on page 23.
System Accessories
The
Installation
shown on page 5 is only a guide for
selecting and installing system components and acces-
sories. Contact your Graco distributor for assistance in
designing a system to suit your particular needs.
See page 22 for accessories available from Graco. To
ensure maximum pump performance, be sure that all
accessories used are adequately sized and pressure–
rated to meet the system’s requirements.
WARNING
Two accessories are required in your system: a
bleed–type master air valve (D) and a fluid drain
valve (E). These accessories help reduce the risk
of serious bodily 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
pump is shut off. Trapped air can cause the pump
to cycle unexpectedly and result in serious bodily
injury, including amputation. Locate the valve close
to the pump.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun/dis-
pensing valve when shutting off the pump. Trigger-
ing the gun/valve to relive pressure may not be
sufficient, especially if there is a clog in the hose or
gun/valve.
Air Line Accessories
Install the following accessories in the order shown in
the Typical Installation, using adapters as necessary:
An
air line lubricator (B)
provides automatic air
motor lubrication.
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
WARN-
ING
at left). Be sure the bleed valve is easily acces-
sible from the pump, and is located
downstream
from the air regulator.
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.
A second
bleed–type air valve (F)
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).
Connect the Hoses
Connect a grounded air supply hose (G) to supply air
to the pump’s 1/4 npt(f) air inlet. Connect a grounded
fluid hose (H) to the 1/2 npt(f) fluid outlet.
