WARNING

Warnings

Installation
Grounding (All Pumps)
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump: use the ground wire and clamp supplied.
Remove the ground screw (air-powered packages) or
loosen the grounding lug locknut and washer (hydrau-
lic-powered packages). Install the 1.5 mm2(12 ga) mini-
mum ground wire and tighten the screw or locknut
securely. Connect the clamp to a true earth ground.
Air and fluid hoses: use only electrically conductive
hoses.
Air compressor: follow manufacturer's recommenda-
tions.
Dispense valve: ground through connection to a prop-
erly grounded fluid hose and pump.
Fluid supply container: follow your local code.
Object being sprayed: follow your local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the dispense
valve firmly to the side of a grounded metal pail, then
trigger the valve.
Location
When selecting the location for the pump, keep the fol-
lowing in mind:
• There must be sufficient space on all sides of the
pump for installation, operator access, repair, and
air circulation. See Dimensions, page 18.
• Ensure that the floor stand (2) is level in all direc-
tions. If necessary, level the stand using metal
shims. Secure the stand to the floor using 1/2 in. (13
mm) anchors that are long enough to prevent the
pump from tipping. See Dimensions, page 18, for
mounting hole layout.

Air-Powered Pumps
• Reference numbers and letters in parentheses in
the text refer to numbers and letters in the illustra-
tions.
•F
IG. 2, page 9, shows a typical installation of an
air-powered pump. It is only a guide. Contact your
Graco distributor for actual system designs.
• Be sure all accessories, including air lines and fluid
lines, are adequately sized and pressure-rated to
meet system requirements.
• Use only electrically conductive hoses. Fluid hoses
must have spring guards on both ends.
Air Line Accessories
Install the following accessories as shown in FIG. 2,
using adapters as necessary.
•Bleed type master air valve (J) is required in your
system to shut off the air supply to the pump. When
closed, the valve will bleed off all air in the pump. Be
sure the valve is easily accessible from the pump.
•Air regulator (H) 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.
•Air line filter (L) removes harmful dirt and moisture
from the compressed air supply. Also, install a drain
valve at the bottom of each air line drop, to drain off
moisture.
•Air shutoff relief valve (M) isolates the air line
accessories for servicing. Locate upstream from all
other air line accessories.
•DataTrak: see the NXT air motor manual 311238 for
DataTrak information.
Fluid Line Accessories
Install the following accessories as shown in FIG. 2,
using adapters as necessary.
• Install a fluid shutoff valve at each valve drop, to
isolate the valve and fluid accessories for servicing.
• Install a fluid drain valve near the pump fluid outlet,
and at each valve station. The drain valves are
required in your system to relieve fluid pressure in
the displacement pump, hose and valve. Drain
valves at the valve stations may be mounted in the
base of a fluid regulator, using an adapter.
•Fluid regulator controls fluid pressure to the valve,
and dampens pressure surges.
•Dispense valve dispenses the fluid.
•Valve swivel allows freer valve movement.
A bleed type master air valve (J) is required to help
reduce the risk of serious injury, including fluid injection
and splashing of fluid in the eyes or on the skin, and
injury from moving parts if you are adjusting or repair-
ing the pump.
The bleed valve shuts off the air to the pump and
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.

Hydraulic-Powered Pumps
• Reference numbers and letters in parentheses in
the text refer to numbers and letters in the illustra-
tions.
•F
IG. 3, page 11, shows a typical installation of an
hydraulic-powered pump. It is only a guide. Contact
your Graco distributor for actual system designs.
• Be sure all accessories, including hydraulic lines
and fluid lines, are adequately sized and pres-
sure-rated to meet system requirements.
• Use only electrically conductive hoses. Fluid hoses
must have spring guards on both ends.
Always plug the hydraulic inlets, outlets and lines when
disconnecting them for any reason to avoid introducing
dirt and other contaminants into the system.
Be sure that your hydraulic power supply is equipped
with a suction filter to the hydraulic pump and a system
return line filter of 10 micron size. Carefully follow the
manufacturer's recommendations on reservoir and filter
cleaning and periodic changes of hydraulic fluid.
NOTE: Hydraulic fluid is exhausted from differential
hydraulic motors only on the upstroke of the operating
cycle. The oil return line must have at least twice the
flow capacity as the oil supply line. Otherwise, back
pressure on the hydraulic motor piston will slow down
the motor and the fluid displacement pump, resulting in
a loss of pump performance.
On the hydraulic oil supply line (D), install a shutoff valve
(E) to isolate the system for servicing; a fluid pressure
gauge (J) to monitor hydraulic oil pressure to the motor
and avoid overpressurizing the motor or displacement
pump; a pressure- and temperature-compensated flow
control valve (H) to prevent the motor from running too
fast; a pressure reducing valve (K) with a drain line (M)
running directly into the hydraulic return line (T); and an
accumulator (L) to reduce the hammering effect caused
by the motor reversing direction.
On the hydraulic return line (T), install a shutoff valve (S)
for isolating the motor for servicing.
NOTICE
The Hydraulic Power Supply must be kept clean at all
times to avoid damage to the motor and hydraulic
power supply.
Blow out hydraulic lines with air and flush thoroughly
before connection to the motor.
Plug hydraulic inlets, outlets, and line ends when dis-
connecting them for any reason.
