• Graco Inc. does not manufacture or supply any of the reactive chemical materials that may be used in this

equipment and is not responsible for their effects. Because of the vast number of chemicals that could be used
and their varying chemical reactions, before using this equipment, the buyer and the user should determine all
facts relating to the materials used, including any of the potential hazards involved. Particular inquiry and
investigation should be made into potential dangers relating to toxic fumes, fires, explosions, reaction times, and
exposure of human beings to the individual components or their resultant mixtures. Graco assumes no
responsibility for loss, damage, expense or claims for bodily injury or property damage, direct or consequential,

WARNING

TOXIC FLUID HAZARD

Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin,
inhaled, or swallowed.

•

Know the specific hazards of the fluid you are using.

• Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and

national guidelines.

• Any additives to the air supply, such as oil or anti–freeze will be exhausted into the atmosphere.

• Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent

manufacturer.

FIRE AND EXPLOSION HAZARD

Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result
in a fire or explosion and serious injury.

•

Ground the equipment. Refer to Grounding on page 5.

• If there is any static sparking or you feel an electric shock while using this equipment, stop pumping

immediately. Do not use the equipment until you identify and correct the problem.

• Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid being sprayed.

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

• Electrically disconnect all equipment in the work area.

• Extinguish all open flames or pilot lights in the work area.

• Do not smoke in the work area.

• Do not turn on or off any light switch in the work area while operating or if fumes are present.

• Do not operate a gasoline engine in the work area.

MOVING PARTS HAZARD

Moving parts can pinch or amputate your fingers.

•

Keep clear of all moving parts when starting or operating the pump.

• Before servicing the equipment, follow the Pressure Relief Procedure on page 7 to prevent the equipment

from starting accidentally.

FIG.1

NOTE: The terms ISO and RES used in the text refer to

the polyurethane foam chemicals, Isocyanate and Resin.

NOTE: Reference numbers and letters in parentheses in
the text refer to the figure illustrations and the Parts
Drawing.

WARNING

A bleed–type master air valve (E) is required in your
system, to help reduce the risk of serious injury,
including splashing fluid 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 (E) relieves air trapped
between this valve and the pump after the pump is shut
off. Trapped air can cause the pump to cycle
unexpectedly and result in serious injury, including
amputation. Locate the valve close to the pump.

Installing the Feed Pumps

1. Screw the bung adapter (40) and pump tightly into the drum cover. See Fig 1.

2. Tighten the retainer (38) firmly to complete the airtight seal.

3. Separate the two halves of the identification label (15) along the perforation. Clean the surface of the air motor with solvent and apply the appropriate label (RES or ISO) to identify the type of material being pumped.

4. Install an air regulator in the feed pump air inlet to control pump speed. To install, remove the air valve (8) and use suitable adapters for the regulator and pin fitting. Use thread sealer on male threads.

Installation

FIG.2

5. Connect an air supply hose to the 1/4 npt air line
coupler (13). Air supply hoses (103) are supplied in
Kit 217381. See Fig 3, page 6.

6. Connect a fluid supply hose from the 3/4 npt(f) fluid
outlet of the ISO feed pump to the inlet fitting of the
ISO proportioning pump, using adapters as needed.
Then connect a fluid supply hose between the RES
feed pump and RES proportioning pump.

CAUTION

Be sure all hose connections in your polyurethane
foam spray system are clearly labeled ISO or RES
and make connections only with identically labeled
components to avoid material crossing.

Crossing polyurethane materials will cause the
material to harden in the equipment and may
permanently damage it.

Grounding

Remove the ground screw (Z) and insert through eye of
ring terminal at the end of ground wire (Y). Fasten ground
screw back onto pump and tighten securely. See Fig 2.
Connect the other end of the wire to a true earth ground.
Order Part No. 222011 Ground Wire and Clamp.

Feed Pump Kit Installation

The following instructions assume you are using this kit
with a Graco Foam–Cat Sprayer.

WARNING

Static electricity is created by the high velocity flow of
fluid through the pump and hoses. If every part of the
spray system, and all objects in the spray area are not
properly grounded, the static electricity may cause
sparking. Sparks can ignite fumes from solvents and the
fluid being sprayed, dust particles, and other flammable
substances, causing a fire, explosion and serious bodily
injury and property damage.

To reduce the risk of static sparking, use only conductive
air and fluid hoses and be sure your entire system is
properly grounded. Ground the feed pumps as
explained below.

1. Install the feed pumps as described in Steps 1–4, on
page 4.

2. Mount the Air Dryer (105) in any suitable location.
Refer to manual 307548 for the mounting hole
diagram. See Fig 3.

3. Unscrew the air dryer ring (F) to remove the bowl.
See Fig 3. Remove the filter and fill the bowl with the
desiccant, provided. Reassemble.

CAUTION

One end of each fluid hose and each drum nipple (G)
of the drum fittings (H) is labeled ISO or RES. Make
only ISO to ISO and RES to RES connections to avoid
material crossing.

4. Install the drum fittings (H) in the 3/4 in. vent port of
the proper drum.
