Important Two-Component Material Information
Important Two-Component Material Information
Isocyanate Conditions
Spraying or dispensing materials containing
isocyanates creates potentially harmful mists, vapors,
and atomized particulates.
Read material manufacturer’s warnings and material
MSDS to know specific hazards and precautions
related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufficient
ventilation in the work area. If sufficient ventilation is
not available, a supplied-air respirator is required for
everyone in the work area.
To prevent contact with isocyanates, appropriate
personal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
Material Self-ignition
Some materials may become self-igniting if applied
too thick. Read material manufacturer’s warnings and
material MSDS.
Keep Components A and B
Moisture Sensitivity of Isocyanates
Isocyanates (ISO) are catalysts used in two component
foam and polyurea coatings. ISO will react with moisture
(such as humidity) to form small, hard, abrasive crystals,
which become suspended in the fluid. Eventually a film
will form on the surface and the ISO will begin to gel,
increasing in viscosity. If used, this partially cured ISO
will reduce performance and the life of all wetted parts.
NOTE: The amount of film formation and rate of crystallization varies depending on the blend of ISO, the
humidity, and the temperature.
To prevent exposing ISO to moisture:
• 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 wetcup or reservoir (if installed)
filled with Graco Throat Seal Liquid (TSL
206995. The lubricant creates a barrier between the
ISO and the atmosphere.
• Use moisture-proof hoses specifically designed for
ISO.
• Never use reclaimed solvents, which may contain
moisture. Always keep solvent containers closed
when not in use.
• Never use solvent on one side if it has been contaminated from the other side.
• Always lubricate threaded parts with TSL or grease
when reassembling.

Cross-contamination can result in cured material in
fluid lines which could cause serious injury or
damage equipment. To prevent cross-contamination
of the equipment’s wetted parts, never interchange
component A (isocyanate) and component B (resin)
parts.

above 90°F (33°C) when not under pressure, especially
if agitated. To reduce frothing, minimize preheating in a
circulation system.
Important Two-Component Material Information
Changing Materials
• Changing material types used in your sprayer
requires special attention to avoid equipment damage and downtime.
• Always clean the fluid inlet strainers after flushing.
• When changing between epoxies and urethanes or
polyureas, disassemble and clean all fluid components and changes hose sets.
• Check with your material manufacturer for chemical
compatibility.
• Most materials use ISO on the A side, but some use
ISO on the B side.
• Epoxies often have amines on the B (hardener)
side. Polyureas often have amines on the B (resin)
side.

Overview
Usage
The XP70 plural-component sprayer is a mechanical
fixed ratio sprayer that can mix and spray most two-component epoxy and urethane protective coatings. When
using quick-setting material (less than 10 minute pot life)
a remote mix manifold must be used.
The two pumps are carbide seat severe duty positive
displacement pumps that displace fluid on both strokes
simultaneously on ratio to one another.
XP70 sprayers are not approved for use in hazardous
locations unless the base model, all accessories, all
kits, and all wiring meet local, state, and national
codes. See Important Two-Component Material
Information, page 7, to determine the appropriate
location for your particular sprayer model.
Overview
Over Pressure Protection
Mechanically linked pumps can create excessive fluid
pressure if the full motor force is applied to only one
of the fluid pumps.
• Maximum air pressure set point blow off valves
are provided to limit maximum fluid pressure. Do
not remove these valves.
• Automatic pressure relief valves are used to
dump excess pressure back to the supply. Never
plug these return hoses.
• Common handles link the fluid control valves.
Never install individual shut off valves on the “A”
and “B” lines.
• On models other than 1:1 mix ratio, a rupture disc
is provided on the small side fluid pump as a
back-up to the over pressure relief valve. If the
rupture disc ever opens, do not operate the
machine until the over pressure valve and the
rupture disc have been replaced.

Component Identification
Air Line
Bleed-type master air valve (CA): required in your sys-
tem to relieve air trapped between it and the air motor
when the valve is closed.
Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.
• Be sure the valve is easily accessible from the pump
and located downstream from the air regulator.
• Pump air regulator (CB): to control pump speed
and outlet pressure.
• Air line filter (C): 40 micron filter that removes
harmful dirt and moisture from compressed air supply. Accumulated water is automatically drained
from the filter.
Fluid Line Accessories
Optional Accessories
• Optional Fluid Heaters (N): to heat the resin and
hardener before mixing. Improves the chemical
reaction and lowers viscosity to improve the spray
pattern.
• Optional Solvent Flush Kit (G): to flush the mix
manifold. Includes a solvent pump, mounting hardware, and solvent supply hose.
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
Empty and Flush Entire System (new sprayer or end
of job), page 27.
• Fluid Manifold (AA): mounts fluid gauges and over
pressure relief valves. Controls circulation and
pump priming.
• Mix Manifold (AB): brings A and B fluid together.
Provides control and check valves for A, B, and flush
fluids.
• Circulation Handle (AC): open to relieve fluid pres-
sure, prime pumps, and circulate material in hoppers. Close to spray mixed material.
• Dual Shutoff Handle (AE): Controls A and B on/off
flow into mix manifold. Press down to provide A and
B fluid to the mix manifold and into the static mixer
for spraying. Press up to turn off A and B before
flushing the mixed material.
• Solvent Flush Valve (AD): to flush solvent through
mix manifold, hose, and spray gun.
• Static mixer/gun hose kit: to mix the two fluids and
deliver mix to the spray gun. Includes static mixer
and hoses to the spray gun.

Location
XP70 sprayers are approved for use in hazardous
locations only if the base model, all accessories, all
kits, and all wiring meet local, state, and national
codes.
1. Locate the proportioner on a level surface.
2. Position the proportioner for convenient operator
access and maintenance, safe routing of air and
fluid lines, and easy connection of components and
accessories.
3. For permanent mounting, remove wheels and
mount the frame to the floor. See Dimensions,
page 54.
4. Ensure that the cart brake (L) is in the locked position.
Pump: use ground wire and clamp (supplied). Loosen
grounding lug locknut (W) and washer (X). Insert ground
wire end (Y) into lug (Z) slot and tighten locknut
securely. Connect ground clamp to a true earth ground.
Y
W, X, Z
Solvent Pump: use ground wire and clamp (supplied
with solvent pump). Follow instructions in pump manual.
Air and fluid hoses: use only static dissipation type
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.
Air compressor: follow manufacturer’s recommendations.
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.
Spray gun: 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
firmly to the side of a grounded metal pail, then trigger
the gun.

Wire Sprayers with Explosion-Proof Heaters
(Hazardous location sprayers only)
If your sprayer is rated for hazardous areas, and you
have explosion-proof heaters, you must have a qualified electrician connect heater wiring. Ensure wiring
and installation comply with local electrical codes for
hazardous areas.
Improperly installed or connected equipment will create
a hazardous condition and cause fire, explosion, or electric shock. Follow local regulations.
When explosion-proof heaters are used, ensure the wiring, wiring connections, switches, and electrical distribution panel all meet flame-proof (explosion-proof)
requirements.
Setup
Refer to the Viscon HP heater manual for electrical connection instructions and guidelines in hazardous locations.
