WARNING

Important Isocyanate (ISO) Information
312749K 5
Important Isocyanate (ISO) Information
Isocyanates (ISO() are catalysts used in two component materials.
Isocyanate Conditions Keep Components A and B
Separate
Spraying or dispensing fluids that contain
isocyanates creates potentially harmful mists,
vapors, and atomized particulates.
•Read and understand the fluid manufacturer’s
warnings and Safety Data Sheets (SDSs) to know
specific hazards and precautions related to
isocyanates.
•Use of isocyanates involves potentially hazardous
procedures. Do not spray with this equipment
unless you are trained, qualified, and have read
and understood the information in this manual
and in the fluid manufacturer’s application
instructions and SDSs.
•Use of incorrectly maintained or mis-adjusted
equipment may result in improperly cured
material. Equipment must be carefully maintained
and adjusted according to instructions in the
manual.
•To prevent inhalation of isocyanate mists, vapors,
and atomized particulates, everyone in the work
area must wear appropriate respiratory
protection. Always wear a properly fitting
respirator, which may include a supplied-air
respirator. Ventilate the work area according to
instructions in the fluid manufacturer’s SDSs.
•Avoid all skin contact with isocyanates. Everyone
in the work area must wear chemically
impermeable gloves, protective clothing and foot
coverings as recommended by the fluid
manufacturer and local regulatory authority.
Follow all fluid manufacturer recommendations,
including those regarding handling of
contaminated clothing. After spraying, wash
hands and face before eating or drinking.
Cross-contamination can result in cured material in
fluid lines which could cause serious injury or
damage equipment. To prevent cross-contamination:
•Never interchange component A and component
B wetted parts.
•Never use solvent on one side if it has been
contaminated from the other side.

6 312749K
Moisture Sensitivity of
Isocyanates
Exposure to moisture (such as humidity) will cause ISO
to partially cure, forming small, hard, abrasive crystal
that become suspended in the fluid. Eventually a film will
form on the surface and the ISO will begin to gel,
increasing in viscosity.
NOTE: The amount of film formation and rate of
crystallization varies depending on the blend of ISO, the
humidity, and the temperature.
Changing Materials
NOTICE
Partially cured ISO will reduce performance and the life
of all wetted parts.
•Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere. Never
store ISO in an open container.
•Keep the ISO pump wet cup or reservoir (if
installed) filled with appropriate lubricant. The
lubricant creates a barrier between the ISO and
the atmosphere.
•Use only moisture-proof hoses compatible with
ISO.
•Never use reclaimed solvents, which may contain
moisture. Always keep solvent containers closed
when not in use.
•Always lubricate threaded parts with an
appropriate lubricant when reassembling.
NOTICE
Changing the material types used in your equipment
requires special attention to avoid equipment damage
and downtime.
•When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
•Always clean the fluid inlet strainers after flushing.
•Check with your material manufacturer for
chemical compatibility.
•When changing between epoxies and urethanes or
polyureas, disassemble and clean all fluid
components and change hoses. Epoxies often
have amines on the B (hardener) side. Polyureas
often have amines on the B (resin) side.

Overview
312749K 11
Overview
XM plural-component sprayers can mix most two
component epoxy and urethane protective coatings.
When using quick-setting materials (less than 10 minute
pot life) a remote mix manifold must be used.
The left side of the mix manifold is intended for the
major volume material, or the higher viscosity material if
using a 1:1 volume mix. This side is referred to
throughout the manual as the resin side or “A” side.
The right side is referred to as the Hardener side or “B”
side. The “B” side incorporates a 40 mesh strainer and
an adjustable restrictor for balancing the system back
pressure and flow.
See FIG. 5 to view flow of A and B material inside the
XM Mix Manifold.
The resin and hardener enter the manifold through the
manifold inlet ports. The “A” material flows through the
manifold to the material outlet port. The injector tube
creates a hollow stream of “A” material for the “B”
material to fill once the hardener exits the injector tube.
The mixed resin and hardener material enters the mix
manifold outlet (R) before the mixed material enters the
integrator fluid hose. Adjust the restrictor housing to
balance the system back pressure and flow.
Always use the integration hose, supplied with your XM
plural-component sprayer, after the mix manifold.
Please follow these recommendations for setup:
•Use at least a 3/8 in. (10 mm) x 25 ft. (7 m)
integrator hose.
•Install at least 24-elements of static mixer after the
integration hose and before the spray gun whip
hose.

Installation
For assistance in setting up a plural component sprayer,
contact your Graco distributor, to ensure that you select
the proper type and size equipment for your system.
Mix Manifold (255684)
A and B Material Inlets
The A and B fluid inlets are equipped with 1/2 in. npsm
unions in 1/2 in. npt(f) ports. Connect 1/2 in., 3/8 in., or
1/4 in. npsm(f) fluid hoses using the two adapter nipples
(provided).
Solvent Inlet
Connect the solvent hose extension (CK) to the solvent
hose (G). Connect the solvent hose extension to the
solvent inlet (AD). Use a Graco approved grounded
hose rated to withstand the maximum fluid working
pressure of the solvent pump. The hose core must be
chemically compatible with the solvent being used such
as nylon or PTFE.
Mixed Material Outlet
Connect a 3/8 in. ID x 25 ft. (minimum) integrator hose
(L) to the fluid outlet. Then connect the static mixer
housing (S) and fluid whip hose (T) to the 3/8 npt(f)
integrator hose (L). Two static mixers are often used, in
series.
Converting to Remote Mounted
Mix Manifold (256980)
A and B Outlet Check Valves
1. Loosen the swivel fittings of the A and B material
inlets (AA, and AB) and remove the mix manifold
(BD).
2. Use the mounting fasteners (BE) to mount the mix
manifold (BD) to the remote carriage (BC).
NOTE: See Mounting Without Carriage on page
13 if not using the remote carriage.
3. Tighten the swivel fittings of the A and B check
valve inlets (BA, BB) to install the A and B outlet
check valves (BH, BJ).
NOTE: The XM proportioner must have outlet check
valves in order to accurately measure pump outlet
flow.
4. Install the restrictor valve (BG) on B check valve
(BJ). The restrictor valve is required at the
proportioner to set the bar graph on the ratio mode
screen (see your XM operation manual).
This manifold is designed for use on proportioning
pumps with independent drive motors. Use of this
manifold on a mechanically linked sprayer without
using mechanically linked on/off A and B valves may
cause hazardous fluid pressures that can rupture
equipment.

Mounting Without Carriage
To mount the bare manifold, drill four holes in the
mounting surface, and secure with four 5/16-18 x 1/2 in.
(50 mm) screws. See the following illustration for details
and dimensions.
Remote Recirculation Kit
(273185)
Parts are provided on the “A” and “B” sides for
recirculating the material back to the proportioner.
To install the remote recirculation kit, install remote
recirculation valves (CH, CJ) on front of remote mix
manifold assembly.
If the recirculation valves leak while you are spraying,
you will be off ratio with no indication. See your XM
proportioner operation manual for more information.

Grounding
14 312749K
Grounding
•Pump: use a ground wire and clamp as instructed
in your sprayer operation manual.
•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 29 megohms,
replace hose immediately.
•Mix manifold and solvent flush system: use only
a Graco approved grounded solvent hose. Not all
heated hoses are grounded, and the mix manifold
primary ground is through the solvent hose. Ensure
that the solvent pump is properly grounded, as
instructed in your solvent pump manual. Ensure
there is electrical continuity from the spray tip to the
grounded solvent hose.
•Air compressor: Follow manufacturer’s
recommendations.
•Spray gun/dispense valve: ground through
connection to a properly grounded fluid hose and
pump.
•Fluid supply container: follow local code.
•Object being sprayed: 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 spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid
contaminating your fluid with oil, flush the equipment
with a compatible solvent before using the equipment.
See Dispensing and Spraying, page 17.
Your system must be grounded to reduce the risk of
static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current. Read the warnings in your
proportioner manual.

1. Follow the Pressure Relief Procedure on page 17.
2. Engage trigger lock. Remove spray tip.
3. Make sure shutoff handles (AH, AJ) and remote
recirculation valves (CH, CJ) are closed.
NOTE: The valve handles point at each other in the
closed position.
4. Open solvent shutoff valve (AK).
5. Turn on solvent flush pump.
6. Disengage spray gun trigger lock.
7. Trigger gun into a grounded metal pail with lid. Use
a lid with a hole to dispense through to avoid
splashing. Be careful to keep fingers away from
front of gun. Flush out mixed material until clean
solvent dispenses.
8. Turn off solvent pump air supply.
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest
possible pressure. Read warnings and grounding
instructions in your proportioner manual. If your
system uses heaters, shut off the main power to the
heaters and heated hose control before flushing.
NOTICE
To prevent fluid from setting up in the dispensing
equipment, flush the system frequently. Be sure there
is an adequate amount of solvent in the solvent supply
before spraying.

remote recirculation valves (CH, CJ) if equipped. If
remote recirculations valves are not equipped,
disconnect the material hoses at the inlets (AA, AB).
4. Run pumps until the A and B material in the hose
has dispensed. Salvage the material in separate
clean containers.
5. Wipe the reservoirs clean, then add solvent to each.
Move circulation lines to waste containers.
6. Repeat steps to flush through each side until clean
solvent exits the recirculation hose.
7. Stop the proportioner (see your XM proportioner
manual) and move the recirculation hoses back to
the reservoirs. Continue recirculating until the
proportioner is thoroughly flushed.
8. Close the remote recirculation valve (CH, CJ), if
equipped.
9. Dispense fresh solvent through the mix manifold
valves and through the gun, then close the solvent
shutoff valve (AK).
10. Close the shutoff valves (AH, AJ).
