Warnings

Isocyanate Hazard
Spraying materials containing isocyanates creates
potentially harmful mists, vapors, and atomized
particulates.
Read material manufacturer’s warnings and
material MSDS to know specic hazards and
precautions related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufcient ventila-
tion in the work area. If sufcient 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 thickly. Read material manufacturer’s warnings
and material MSDS.
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 uid. Eventually a lm will
form on the surface and the ISO will begin to gel, increas-
ing in viscosity. If used, this partially cured ISO will reduce
performance and the life of all wetted parts.
The amount of lm formation and rate of crystal-
lization 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 lube pump reservoir lled with Graco • Throat Seal Liquid (TSL), Part 206995. The lubricant
creates a barrier between the ISO and the atmosphere.
Use moisture-proof hoses specically 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 contami-• nated from the other side.
Always park pumps when you shutdown.•
Always lubricate threaded parts with Part 217374 ISO• pump oil or grease when reassembling.

Warnings

Keep Components A and B
Separate
CAUTION
To prevent cross-contamination of the equipment’s wet-
ted parts, never interchange component A (isocyanate)
and component B (resin) parts. The gun is shipped with
the A side on the left. The uid manifold, uid hous-
ing, side seal assembly, check valve cartridge, and mix
chamber are marked on the A side.
Foam Resins with 245 fa
Blowing Agents
New foam blowing agents will froth at temperatures above
90°F (33 °C) when not under pressure, especially if agitat-
ed. To reduce frothing, minimize preheating in a circulation
system.
Changing Materials
When changing materials, ush the equipment mul-• tiple times to ensure it is thoroughly clean.
Always clean the uid inlet strainers after ushing.•
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.

Section 1 - Installation: Equipment Assembly
How The Gun Works
The Probler Gun is used to spray or pour two-
component, low viscosity polyurethane foam materials
at outputs up to 60 pounds per minute. The gun
features an air-assited full-nger trigger and a
patented solvent-free automatic air-purge cleaning
system.
The trigger actuates a small valve in the gun handle
that controls the ow of air into the piston assembly.
When the trigger is pulled, air ows through the valve to
the front of the piston. Air pressure forces the piston to-
wards the rear of the gun, simultaneously closing off
the purge air and moving the mixing chamber to a
position where the mixing chamber orices are aligned
with the orices in both the side block seal and
check valve assemblies.
The proper alignment of the orices is determined by
the setting of the Set Screw, p/n GC0143, located
at the rear of the piston assembly. This set screw
determines the length of travel of the air piston and
has been preset at the factory and should not require
adjustment. (SEE MAINTENANCE SECTION)
The two uids (isocyanate and polyol) then ow through
the material shut-off valves, seal, and check valve
assemblies and into the mixing chamber. The two
uids impinge against one another and exit the mixing
chamber in a swirling, conical spray pattern.
When the trigger is released, the mixing chamber
returns to its original position and purge air ows into
the mixing chamber housing. The front
tip o-ring, keeps air purge inside the gun
head, forcing all of the air through the
orices in the mixing chamber, for a complete, total and
constant purge.
This purge air continues to ow through the mixing
chamber until the air switch, is pulled up to shut-off all
air to the gun; or until the trigger is pulled again.
