Warnings

Warnings

The following warnings are for the setup, use, grounding, maintenance and repair of this equipment. The
exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific
risks. When these symbols appear in the body of this manual refer back to these Warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual
where applicable.

WARNING

SKIN INJECTION HAZARD

High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce
skin. This many look like just a cut, but it is a serious injury that can result in amputation.
Get immediate surgical treatment.

• Do not point dispensing device at anyone or at any part of the body.

• Do not put your hand over the fluid outlet.

• Do not stop or deflect leaks with you hand, body, glove, or rag.

• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning,
checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses and couplings daily. Replace work or damaged parts immediately.

MOVING PARTS HAZARD
Moving parts can pinch, cut or amputate fingers and other body parts.

• Keep clear of moving parts.

• Do not operate equipment with protective guards or covers removed.

• Pressurized equipment can start without warning. Before checking, moving, or servicing
equipment, follow the Pressure Relief Procedure and disconnect all power sources.

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help
prevent fire and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and
plastic drop cloths (potential static arc).

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords, or turn light switches on or off when flammable fumes
are present.

• Ground all equipment in the work area. See Grounding instructions.

• Use Only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use
equipment until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

WARNING

EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.

• Do not operat

• Do not exceed the maximum working pressure or temperature rating of the lowest rated
system component. See Technical Data in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data
in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete
information about your material, request MSDS from distributor or retailer.

• Do not leave
equipment

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine
manufacturer’s replacement parts only.

• Do not alter or modify equipment.

• Use equip

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or over bend hoses or use hoses to pull equipment.

•Keepchil

• Comply with all applicable safety regulations.

SPLATTER HAZARD
Hot or toxic fluid can cause serious injury if splashed in the eyes or on skin. During blow off of
platen, splatter may occur.

• Use minimum air pressure when removing platen from drum.

Installation

Installation

Grounding

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: Connect a ground wire (Graco PN 238909)
to the ground screw on the bottom cover of the air
motor, under the shield. Connect the other end of the
ground wire to a true earth ground.

Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check
electrical resistance of hoses. If total resistance
to ground exceeds 25 megohms, replace hose
immediately.

Air compressors: follow manufacturer’s
recommendations.

Dispense valve: ground through connection to a
properly grounded fluid hose and pump.

Material supply container: follow local code.

Container(s) that receive material: follow 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 surface, 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.

on a surface than can support the
ump and accessories, as well as the
during operation. Do not use air or

upport the pump.

Setup

To avoid contaminating the fluid, pipe the exhaust
air to vent outside of the fluid product area, away
from people, animals, or food handling areas.

Note

Reference numbers and letters in
parentheses in the text refer to the callouts in
the figures and the parts drawings.

Accessories are available from Graco. Make certain
all accessories are sized and pressure rated to meet
your system requirements.

Fig 1 is only a guide for selecting and installing

system components and accessories. Contact your
Graco distributor for assistance in designing a system
to suit your particular needs.

Install a bleed-type master air valve (G) close to the
pump air inlet (D), to relieve air trapped between it
and the air motor.

Install a pump runaway valve (S) in the pump air line
to shut off air to the air motor automatically if the
pump starts to run too fast.

Install another bleed-type master air valve (G)
upstream from all air line accessories and use it to
isolate the accessories during cleaning and repair.

Installation

On the air drop to the dispense valve (K), install an
air regulator (M) to control air pressure to the valve.
Install a bleed valve (G) to use as a shutoff when
servicing the dispense valve.

NOTICE

Do not expose the air motor to temperatures
higher than 120°F (49°C) or the immersed fluid
pump to temperatures higher than 250°F (121°C).
Excessive temperatures may damage the pump

Pressure Relief Procedure

Trappedaircancausethepumptocycle
unexpectedly, which could result in serious injury
from injection, splashing or moving parts. Relieve
pressure when you stop pumping and before
cleaning, checking, or servicing equipment.

Flushing Procedure, page 10. Check national, state,

and local codes for specific limitations.

Adjusting the Pump Speed and
Pressure

Set pressure regulator to 0 psi. Open the bleed-type
master air valve. Adjust the pump air regulator until
the pump is running smoothly.

Allow the pump to cycle slowly until all air is pushed
out of the lines (the fluid will flow in a steady stream
from the fluid outlet) and the pump is primed.

With the air supply turned on, the pump will start
when the dispensing valve is opened and stall
against pressure when the valve is closed. In a
circulating system, the pump operates until the air
supply is turned off.

NOTICE

Never allow the pump to run dry of fluid. A dry
pump will accelerate to a high speed, possibly
damaging itself.

1. Shut off the air supply to the pump.

2. Close the bleed-type master air valve (required
in system).

3. Open the fluid ball valve and/or dispensing valve
to relieve fluid pressure.

Flush

The sanitary pump was assembled using sanitary
lubricant on moving parts and was tested in
water. Flush the pump thoroughly with an
appropriate cleaning solution or disassemble and
sanitize the parts before using the pump. See

Before First Use

If the pump accelerates quickly, or is running too
fast, stop the pump immediately and check the fluid
supply. If the supply is empty and air has been
pumped into the lines, refill the container and prime
the pump and lines with fluid. Be sure to eliminate all
air from the system.

Pump Shut Down

Follow the Pressure Relief Procedure, page 9 .
Always stop the pump at the bottom of its stroke to
prevent fluid from drying on the displacement rod.
(The air motor will exhaust at the bottom or top of
the stroke.)
