• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
PRESSURIZED ALUMINUM PARTS HAZARD
Use of uids that are incompatible with aluminum in pressurized equipment can cause serious chemical
reaction and equipment rupture. Failure to follow this warning can result in death, serious injury, or property
damage.
• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or uids
containing such solvents.
• Do not use chlorine bleach.
• Many other uids may contain chemicals that can react with aluminum. Contact your material supplier
for compatibility..

Important Isocyanate (ISO)
Information
Isocyanates (ISO) are catalysts used in two component
materials.
Isocyanate Conditions
Spraying or dispensing uids that contain isocyanates creates potentially harmful mists, vapors, and atom-
ized particulates.
• Read and understand the uid manufacturer’s warnings and Safety Data Sheet (SDS) to know spe-
cic hazards and precautions related to isocyanates.
• Use of isocyanates involves potentially hazardous procedures. Do not spray with this equipment un-
less you are trained, qualied, and have read and understood the information in this manual and in
the uid manufacturer’s application instructions and SDS.
• 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 ad-
justed 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 tting respirator, which may
include a supplied-air respirator. Ventilate the work area according to instructions in the uid manufac-
turer’s SDS.
• 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 uid manufacturer and local
regulatory authority. Follow all uid manufacturer recommendations, including those regarding han-
dling 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 specied by the uid manufacturer. Generally this time period is at least 24 hours.
• Warn others who may enter work area of hazard from exposure to isocyanates. Follow the recommen-
dations of the uid manufacturer and local regulatory authority. Posting a placard such as the follow-
ing outside the work area is recommended:

Warnings

Material Self-ignition
Some materials may become self-igniting if applied to thick.
Read material manufacturer’s warnings and Safety Data
Sheet (SDS).
Keep Components A and B
Separate
Cross-contamination can result in cured material in uid
lines which could cause serious injury or damage equip-
ment. To prevent cross-contamination:
• Never interchange component A and component B
wetted parts.
• Never use solvent on one side if it has been contami-
nated from the other side.
Moisture Sensitivity of
Isocyanates
Exposure to moisture (such as humidity) will cause ISO to partially
cure, forming small, hard, abrasive crystal that become suspend-
ed in the uid. Eventually a lm will form on the surface and the
ISO will begin to gel, increasing in viscosity.
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.
• Keep the ISO pump wet cup or reservoir (if installed)
lled with appropriate lubricant. The lubricant creates a
barrier between the ISO and the atmosphere.
• Use only moisture-proof hoses compatible with ISO.
• Never use reclaimed solvents, which may contain mois-
ture. Always keep solvent containers closed when not in
use.
• Always lubricate threaded parts with an appropriate lubri-
cant when reassembling.
NOTE: The amount of lm formation and rate of crystallization
varies depending on the blend of ISO, the humidity, and the tem-
perature.
Foam Resins with 245 fa
Blowing Agents
Some foam blowing agents will froth at temperatures abov 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 attnetion to avoid equipment damage and downtime.
• When changing materials, ush the equipment multiple
times to ensure it is thoroughly clean.
• Always clean the uid inlet strainers after ushing.
• Check with your material manufacturer for chemical
compatibility.
• When changing between epoxies and urethanes or
polyureas, disassemble and clean all uid components
and change hoses. Epoxies often have amines on the B
(hardener) side. Poluureas often have amines on the B
(resin) side.

GCP4RX Auto Probler P2 Dispense Gun
313267 User Manual
Section 1 - Installation: Standard Equipment

How The Gun Works
The air on / off ports actuate the gun’s piston. When air is
applied to the “on” port the air pressure forces the piston
towards 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 assem-
blies.
The proper alignment of the orices is determined by
the setting of the adjustment nut, located on the pis-
ton lock assembly. This adjustment nut determines
the length of travel of the air piston and has been
preset at the factory and should not require adjust-
ment. (SEE MAINTENANCE SECTION)
The two uids (isocyanate and polyol) then ow through
the material shut-off valves, seal, and check valve assem-
blies and into the mixing chamber. The two uids impinge
against one another and exit the mixing chamber in a swirl-
ing, 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 in-
side 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 cham-
ber until the air switch is pulled up to shut-off all air to the
gun; or until the trigger is pulled again.
Piston Lock
Engage piston lock whenever you stop spraying, to avoid
accidental triggering.
Always use piston lock in conjunction with uid ball valves
to avoid accidental triggering.
Read warnings, page 3.
To engage Piston lock: push knob in and turn clockwise.
If engaged, gun will not actuate.
To disengage piston lock: push knob in and turn coun-
terclockwise until it pops out. There will be a gap between
knob and gun body.
See page 19 for piston lock adjustment or installation.
Loss of Air Pressure
In event of loss of air pressure, gun will continue to spray.
To shut off gun, do one of the following:
• Push in piston lock, see Engage piston lock.
• Close ball valves A and B.
