3A8502A 5
Important Isocyanate (ISO) Information
Isocyanates (ISO) are catalysts used in two component materials.
Isocyanate Conditions
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, which could
cause off gassing and offensive odors. 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.
• Hazard from exposure to isocyanates continues after spraying. Anyone without appropriate personal protective
equipment must stay out of the work area during application and after application for the time period specified
by the fluid manufacturer. Generally this time period is at least 24 hours.

Material Self-Ignition
Keep Components A and B
Separate
Moisture Sensitivity of
Isocyanates
Exposure to moisture (such as humidity) will cause ISO
to partially cure, forming small, hard, abrasive crystals
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.
Some materials may become self-igniting if applied
too thick. Read material manufacturer’s warnings and
Safety Data Sheets (SDSs).
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.
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.
• 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.

Foam Resins with 245 fa
Blowing Agents
Some foam blowing agents will froth at temperatures
above 90 °F (33 °C) when not under pressure,
especially if agitated. To reduce frothing, minimize
preheating in a circulation system.
Changing Materials
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.
• 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.

Grounding
Pump: Verify that the ground screw (GS) is attached
and tightened securely to the pump body. Connect the
other end of the ground wire (U) to a true earth ground.
When installed in a truck or trailer, connect the ground
wire (U) to the frame of the truck or trailer.
The following items are sold separately:
Air compressor: Ground according to manufacturer
recommendations.
Air and fluid hoses: Use only electrically conductive
hoses with a maximum of 300 ft (91 m) combined hose
length to ensure grounding continuity. Check electrical
resistance of hoses. If total resistance to ground
exceeds 29 megohms, replace the hose immediately.
Fluid supply container: 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 non-conductive
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.
A bleed-type master air valve (AD) and a fluid drain
valve (AE) are 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
when you are adjusting or repairing the pump.
• The bleed-type master air valve (AD) 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. Install the valve close to the
pump.
• The fluid drain valve (AE) helps relieve pressure in
the displacement pump and fluid supply lines
when shutting off the pump. Actuating the gun to
relieve pressure may not be sufficient, especially if
there is a clog in the hose or the spray gun.
The equipment 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.
