WARNING

Warnings

63A0096B

Installation

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.

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.
