The following is not included in this kit, but required:
(1) 7834-07 Elbow Fitting (Connection To Air Manifold)
XX-9704-53 Black AAC Tubing (XX= YOU MUST SPECIFY TUBING LENGTH BY FEET)
EXAMPLE: If standard machine hose length is 25ft, it is recomended to order 28ft. of 9704-53.
Required: qty. (1) 7716-06C set screw.
Remove: 23765-00 Chopper mounting assembly and place 7716-06C set screw in middle tapped
hole - (USE THREAD LOCKER MEDIUM STRENGTH TO KEEP FROM LEAKING)
Reason: To remove extra weight and bulk from the gun, for gelcoat application.
Delete: qty. (4) 8212-48F shoulder screw, Keep and use existing 8212-32F shoulder screws.

Isocyanate Conditions
Material Self-ignition
Moisture Sensitivity of
Isocyanites
Isocyanites (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.
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 lube pump reservoir (if installed) filled
with Graco Throat Seal Liquid (TSL), Part 206995.
The lubricant creates a barrier between the ISO and
the atmosphere.
• Use moisture-proof hoses specifically designed for
ISO, such as those supplied with your system.
• 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 contam-
inated from the other side.
• Always lubricate threaded parts with ISO pump oil
or grease when reassembling.
Keep Components A and
B Separate
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.
Spraying materials containing isocyanates creates
potentially harmful mists, vapors, and atomized partic-
ulates.
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 ventila-
tion 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 per-
sonal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.
The amount of film formation and rate of crystalli-
zation varies depending on the blend of ISO, the
humidity, and the temperature.
NOTICE
To prevent cross-contamination of the equipment’s
wetted parts, never interchange component A (isocy-
anate) and component B (resin) parts.
