INSTALLATION
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and
the parts drawing.
See pages 18 and 19 for accessories available
from Graco. If you supply your own accessories,
be sure they are adequately sized and pressure–
rated to meet the system’s requirements.
The Typical Installation shown on page 4 is only a guide
for selecting and installing system components and ac-
cessories. Contact your Graco representative or Graco
Technical Assistance (see back page) for assistance in
designing a system to suit your particular needs.
SYSTEM ACCESSORIES
Refer to the Typical Installation drawing on page 4.
Two accessories are required in your system: a
bleed–type master air valve (J) and a fluid drain
valve (N). These accessories help reduce the risk
of serious bodily injury including fluid injection,
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. 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.
WARNING
Air and Fluid Hoses
Be sure all air and fluid hoses are properly sized and
pressure–rated for your system. Use only grounded air
and fluid hoses. Fluid hoses must have spring guards on
both ends.
Mounting Accessories
Mount the pump (A) to suit the type of installation
planned. The pump dimensions and mounting hole lay-
outs are shown on pages 24 and 25.
The Typical Installation on page 4 shows the pump (A)
mounted on a pneumatic elevator cart (B). The pump
may also be mounted on a 19 liter (5 gal.) pail ram. In ei-
ther case, it is used with a wiper plate (C). Refer to Acces-
sories on page 19 and the separate manuals for the cart,
ram, and wiper plate for further information.
Kits 223–881 and 224–829 are available to mount the
pump on a 200 liter (55 gallon) ram. Refer to Accessories
on page 19 and the separate manuals included with the
kits for further information.
Air Line Accessories
Install the following accessories in the order shown in the
Typical Installation, using adapters as necessary:
A pump runaway valve (G ) senses when the pump
is running too fast and automatically shuts off the air to
the motor. A pump which runs too fast can be serious-
ly damaged. Install closest to the pump air inlet.
An air line lubricator (H)
provides automatic air mo-
tor lubrication.
A bleed–type master air valve (J) is required in your
system to relieve air trapped between it and the air
motor when the valve is closed (see the
WARNING
at
left). Be sure the bleed valve is easily accessible from
the pump, and is located
downstream
from the air
regulator.
An air regulator (K) 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.
An air line filter (L) removes harmful dirt and mois-
ture from the compressed air supply.
A second bleed–type air valve (M)
isolates the air
line accessories for servicing. Locate upstream from
all other air line accessories.
An air line quick disconnect coupler (F) is required
for pumps mounted on the pneumatic elevator cart.
The female coupler attaches to the end of the air hose
(D), and the male coupler screws into the air manifold
(E). See the separate cart manual for further informa-
tion.
Fluid Line Accessories
Install the following accessories in the positions shown in
the Typical Installation, using adapters as necessary:
A fluid drain valve (N) is required in your system to
relieve fluid pressure in the hose and gun (see the
WARNING
at left). Screw the drain valve into the
open branch of a tee mounted in the fluid line. Install
the drain valve pointing down, but so the handle points
up when opened.
A fluid regulator (P) controls fluid pressure to the
gun/valve, and dampens pressure surges.
A gun or valve (S)
dispenses the fluid. The gun
shown in the Typical Installation is a dispensing gun
for highly viscous fluids.
A gun swivel (T)
allows freer gun movement.
GROUNDING
WARNING
Before operating the pump, ground the system as
explained under FIRE OR EXPLOSION HAZARD
and
Grounding
on page 3.
