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.

Pre operation Checklist
Check that all ttings are tight and air regulators are
turned to “zero pressure”.
Do not place any part of the body in the path of the
material spray.
Do not point the gun at or near other personnel.
Do not look into the mixing chamber orice at any time.
Because of the hazardous materials used in this
equipment, it is recommended that the operator use an
air mask, goggles, protective clothing, and other safety
equipment as prescribed by current regulations, recom-
mendations of the chemical suppliers, and the laws in
the area where the equipment is being used.
Operating Requirements
• 8-10 CFM at 90-110 psi (0.62-0.76 MPa,
6.2-7.6 bar)
• MAXIMUM Static Fluid Pressure - 3000 psi (20.7
MPa, 207 bar)
The GlasCraft Probler Gun is designed and manufac-
tured to operate at a maximum static uid pressure not
to exceed 3000 psi (20.7 MPa, 207 bar). When attached
to a GlasCraft proportioning system, this pressure will
not be exceeded. However, if the GlasCraft Probler Gun
is installed on any other manufacturer’s self-designed
equipment, great care must be taken to ensure that the
maximum static uid pressure not be exceeded.
If the gun is being used for short periods of spraying,
GlasCraft recommends that the purge air be left ON.
If purge air is to be turned OFF, BOTH MATERIAL SHUT-
OFF VALVES, MUST BE TURNED TO THEIR “OFF” POSI-
TION BEFORE TURNING “OFF” THE PURGE AIR !
Failure to follow this procedure will possibly result in the gun
head becoming encased with mixed product.
For proper purging following use, the air switch must be left
OPEN for at least 15 SECONDS after the trigger has been
released.
The ow of material into the mixing chamber is controlled by
the ON or OFF position of the two material shut-off valves.
Both material shut-off valves must be FULLY OPEN
during dispensing and must be FULLY CLOSED during
service or extended shut-down periods.
BEFORE REMOVING SIDEBLOCK SCREWS, BOTH MA-
TERIAL SHUT-OFF VALVES MUST BE TURNED TO THEIR
“OFF” POSITION. TRIGGER GUN SEVERAL TIMES TO
DEPRESSURIZE GUN .
Failure to follow this procedure will possibly result in the gun
head becoming encased with mixed product.
ON OFF
Refer to system manuals for start-up and
shut-down procedures.

Section 2 - Operation: Start-Up Instructions
Initial Start-Up Procedure
With all material and air lines connected, the gun is now
ready for start-up.
1. Remove the side blocks on the front housing of the
gun, by removing screws.
2. Place separate clean containers under each
individual side block. Open manual material
valves (black arrow forward, see Fig. 4 and Fig. 5)
on each side block simultaneously to allow trapped
air to escape the hose and material to ow into the
containers until all air is purged from the material
system. (See Fig. 3)
3. Close manual material valves simultaneously.
Material pressure gauges on each Heater should
now register approximately equal pressure. If one
side registers considerably more pressure than the
other side, go to the high pressure side and bleed
off some pressure by slightly opening the manual
material valve on the side block over the container.
Bleed pressure until both sides are approximately
the same pressure.
4. Dispose of waste material properly and in accord-
ance with chemical suppliers, instructions and local,
state and federal regulations.
Before re-assembling side blocks, lubrication can
be applied by dabbing a white lithium grease into
holes inside of gun front housing and wiping grease
over side block seals. Grease will purge itself when
air valve is turned on at gun and gun is triggered.
5. Clean and lubricate side blocks and seals thoroughly
and reassemble onto gun. Make certain that side
block screws are tightened securely.
6. Turn purge air and material valves on at gun.
(See Fig. 4 and Fig. 5).
Remember to dispense one to two gallons of mat-
erial to clear the system of grease and plasticizer
that was used during factory testing.
The Polyol will expand in the hose if any normal ope-
rating pressures are bled off whenever the material is
above approximately 75 degrees F. Hot polyol hoses
should never be bled, by any method, to zero pressure
for two reasons.
1. The seals in the gun rely on high pressure to make
their seal. The high pressure cannot be maintained
if the pumps are attempting to apply this pressure
through a hose full of expanded froth; therefore, the
gun seal may leak.
2. Re-starting immediately after hot polyol has expand-
ed in the system may result in spraying substantial
amounts of “bad” foam. This will continue until the
expanded polyol in the primary heater and the hose
has been completely purged.

Section 2 - Operation: Start-Up Instructions
Spray Technique
Always operate safely and follow all safety procedures
outlined.
To achieve the optimum spray pattern for each applica-
tion, several mixing chambers are available.
The standard mixing chamber supplied with your gun
will be adequate for all but the smallest and largest
applications.
Foam rise and cure times will vary according to the
material and substrate temperature. Higher material or
substrate temperature will increase rise and cure times;
lower material or substrate temperatures will decrease
rise and cure times. Consult your chemical manufac-
turer’s data specication sheets for their recommended
spray temperatures. Under most circumstances, both
components will be used at identical temperatures.
Higher pressures and temperatures may be used to
increase material break-up, improve mixing and speed
rise times. With hose lengths over 50 ft., or when mater-
ial viscosities are high, higher material pump pressures
may be necessary.
The gun air switch assembly MUST BE OPENED
(down position) prior to spraying to provide air for trigger
operation and purge air when the trigger is released.
When spraying, the gun trigger may be depressed con-
tinuously, or triggered at the end of each stroke. A smooth,
even layer is best achieved by moving the gun back and
forth in a slow, even motion, overlapping the previous pass
about 50 to 75 percent. DO NOT SPRAY OVER RISING
FOAM! The ideal gun-to-surface distance is about 18 to 24
inches. Be sure to point the gun directly at the surface to be
sprayed. Spraying at an angle to the surface will cause the
foam to be rough and will generate overspray.
