Installation

NOTE: Reference numbers and letters in parentheses

in the text refer to the callouts in the figures and the

Parts Drawing.

If you supply your own accessories, be sure they are

adequately sized and pressure-rated to meet the

system’s requirements.

Contact your Graco distributor for assistance in de-

signing a system to suit your particular needs.

Pump Location and Set-Up

1. Place the unit on a hard, level surface. Check that

the unit is level in all directions. Refer to Dimen-

sions on page 28 to ensure that there is sufficient

overhead clearance for the pump when the ram is

fully raised. Leave room on both sides so the air

regulators will be easily accessible.

2. Read the section System Components and

Accessories on page 9. Connect an air supply

hose to the 1/4 npt(f) main air inlet fitting (57). See

Fig. 2.

3. Unpack the wiper plate (P). Back out the screws

(302) so they will clear the pump intake housing

(11). Raise the ram by setting the ram director

valve switch (36) to the UP position and increasing

the setting of the ram air regulator (27b).

4. Place the wiper plate (P) on a 2 in. thick x 4 in.

wide block of wood. Center the wiper plate and the

wood block on the base, under the pump intake

housing (11).

5. Set the ram air regulator (27b) to zero. Set the ram

director valve switch (36) to the DOWN position.

As the ram unit slowly falls, guide the pump intake

housing (11) into the wiper plate (P).

6. Set the ram air regulator (27b) to 0.07 MPa, 0.7

bar (10 psi). Push down on the pump to install the

wiper plate (P) onto the intake housing (11). Se-

cure the wiper plate to the pump with the two

screws (302).

7. Connect the 660 mm (26 in.) air line tube (76) from

the connector (37) at the air assist valve (18) to

the connector (310) at the wiper plate (P). Refer to

Connecting and Disconnecting Tubes.

Connecting and Disconnecting Tubes

Connection

1. Grasp the tube, then slowly push it straight into the

fitting until it stops.

2. Be sure that the tube is securely connected, and

will not pull out when air pressure is applied. To

check, pull back gently on the tube to ensure that it

will not pull out.

Disconnection

WARNING

To reduce the risk of serious injury whenever you

are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 10.

1. Relieve the pressure.

2. Push evenly on the fitting’s red release button.

3. While holding the release button in, pull the tube

out of the fitting.

4. To reuse the tubing, cut off the previously connec-

tion portion at 90_, being careful not to damage

the outer diameter of the tube. Use of a tube cutter

is recommended. The fitting will leak if the tubing is

not cut at 90_.

System Accessories (See Fig. 2)

WARNING

Two required safety devices are supplied with your

pump: a bleed-type master air valve (8) and a

pump bleeder valve (25). These devices help

reduce the risk of serious 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 air is

shut off. Trapped air can cause the pump to cycle

unexpectedly. The valve is located close to the

pump, downstream from the pump air regulator.

The pump bleeder valve assists in relieving fluid

pressure in the displacement pump, hose, and

dispensing valve. Triggering the dispensing valve to

relieve pressure may not be sufficient.

Supplied Components

The following components are supplied with your

pump.

DThe bleed-type master air valve (8) is supplied

with your system to relieve air trapped between it

and the air motor when the valve is closed (see the

WARNING above).

DThe pump air regulator (27a) controls pump

speed and outlet pressure by adjusting the air

pressure to the pump. The regulator is located

upstream from the bleed-type master air valve.

DThe ram air regulator (27b) controls ram speed by

adjusting the air pressure to the ram, and also

controls the pressure exerted by the wiper plate on

the fluid.

DThe pump bleeder valve (25) is supplied in your

system to relieve fluid pressure in the displacement

pump, hose, and dispensing valve (see the WARN-

ING at left). Be sure the drain hole in the valve is

pointing down. This valve is also used to bleed air

from the pump when priming.

Air Line

Connect an air supply hose to the 1/4 npt(f) main air

inlet fitting (57). Install an air line filter and lubricator in

the main air line. In the main air line, upstream from all

other air line accessories, install a second bleed-type

master air valve to shut off all air to the system and to

isolate the accessories for servicing.

Fluid Line

Connect a fluid hose to the fluid outlet fitting (28).

Connect a suitable dispensing valve to the free end of

the hose.

Operation

Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually relieved to

prevent the system from starting or spraying acci-

dentally. To reduce the risk of an injury from acci-

dental spray from the gun, splashing fluid, or

moving parts, follow the Pressure Relief Proce-

dure whenever you:

Dare instructed to relieve the pressure,

Dstop spraying,

Dcheck or service any of the system equipment,

Dor install or clean the spray nozzle.

1. Shut off the dispensing valve.

2. Shut off the bleed-type master air valve (required

in your system), on the main air line.

3. Close the bleed-type master air valve (supplied

with your pump).

4. Trigger the dispensing valve to relieve pressure.

If you suspect that the dispensing valve, nozzle, or

hose is completely clogged, or that pressure has not

been fully relieved after following the steps above, very

slowly open the pump bleeder valve, having a contain-

er ready to catch the drainage. Leave the pump bleed-

er valve open until you are ready to dispense again.

Very slowly loosen the hose end coupling and relieve

pressure gradually, then loosen completely. Now clear

the nozzle or hose.

WARNING

Keep hands and fingers away from the priming

piston and pump intake during operation and

whenever the pump is charged with air. During

operation, the priming piston extends beyond the

intake housing to pull material into the pump, and

can severely injure or amputate a hand or finger

caught between it and the intake housing. Always

follow the Pressure Relief Procedure at left

before clearing, cleaning, flushing, or servicing any

part of the pump.

The air motor piston and fluid piston (located inside

the air motor cylinder and coupling) also move

when air is supplied to the motor. Do not place your

hand or fingers into the air motor coupling cavity

while the pump is operating.

As the ram is raised and lowered, the wiper plate,

ram tubes, and pump mounting bracket move. To

reduce the risk of pinching or amputation of fingers,

keep you hands away from the wiper plate, lip of

the fluid can, pump bracket, and ram tubes while

the pump is operating.

To reduce the risk of serious injury and damage to

equipment, do not shut off the air supply to the ram

when the ram is raised. Doing so will cause the

pump to fall uncontrolled to the bottom.
