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 specific hazards and precautions related to isocyanates.

Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventilation 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 personal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

Material Self-Ignition

•

•

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 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 contaminated from the other side.

Always park pumps when you shutdown.

Always lubricate threaded parts with Part 217374 ISO pump oil or grease when reassembling.

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 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.

The amount of film formation and rate of crystallization varies depending on the blend of ISO, the humidity, and the temperature.

5

Warnings

Keep Components A and B

Separate

CAUTION

To prevent cross-contamination of the equipment’s wetted parts, never interchange component A (isocyanate) and component B (resin) parts. The gun is shipped with the A side on the left. The fluid manifold, fluid housing, 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 agitated. To reduce frothing, minimize preheating in a circulation system.

•

•

•

•

•

Changing Materials

When changing materials, flush the equipment multiple times to ensure it is thoroughly clean.

Always clean the fluid inlet strainers after flushing.

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.

How The Gun Works

Section 1 - Installation: Equipment Assembly

GlasCraft Equipment

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-finger trigger and a

patented solvent-free automatic air-purge cleaning

system.

The trigger actuates a small valve in the gun handle

that controls the flow of air into the piston assembly.

When the trigger is pulled, air flows 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 orifices are aligned

with the orifices in both the side block seal and

check valve assemblies.

Air Hose is ¼ in. NPS

JIC and SAE Fittings DO NOT require the use of PTFE

tape.

Once the fittings are attached and tight, refer to sys-

tem manuals for start-up instructions.

ISO

The proper alignment of the orifices 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)

*AIR

POLY

The two fluids (isocyanate and polyol) then flow through

the material shut-off valves, seal, and check valve

assemblies and into the mixing chamber. The two

fluids 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 flows into

the mixing chamber housing. The front

tip o-ring, keeps air purge inside the gun

head, forcing all of the air through the

orifices in the mixing chamber, for a complete, total and

constant purge.

This purge air continues to flow 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.

*Fitting GC2394 is an unattached part that may need to

be connected to the air hose first, then connected to the

gun, depending on air hose fitting.

system installation.

See GCP1RX Gun illustration during instructions.

1.

Connect whip hose to gun assembly. The swivel

fittings on the whip hose assembly are sized differ-

ently and will attach only one way. (Match like sized

fittings.) Also connect the air hose assembly to the

gun at this time.

fittings are tight before proceeding:

10

Section 2 - Operation: Start-Up Instructions

Refer to specific system user manuals for complete


Pre operation Checklist

Check that all fittings are tight and air regulators are

turned to “zero pressure”.

WARNING

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.

WARNING

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 orifice 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.

For proper purging following use, the air switch must be left

OPEN for at least 15 SECONDS after the trigger has been released.

The flow 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.

Operating Requirements

WARNING

• 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)

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.

WARNING

The GlasCraft Probler Gun is designed and manufactured to operate at a maximum static fluid 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 fluid pressure not be exceeded.

If the gun is being used for short periods of spraying,

GlasCraft recommends that the purge air be left ON.

ON OFF

Refer to system manuals for start-up and shut-down procedures.

Initial Start-Up Procedure

With all material and air lines connected, the gun is now

ready for start-up.

5.

Clean and lubricate side blocks and seals thoroughly

and reassemble onto gun. Make certain that side

block screws are tightened securely.

1.

Remove the side blocks on the front housing of the

gun, by removing screws.

6.

Turn purge air and material valves on at gun.

(See Fig. 4 and Fig. 5).

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 flow into the

containers until all air is purged from the material

system. (See Fig. 3)

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.

Fig. 4 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.

WARNING

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.

12

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.


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 specification 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 material 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 continuously, 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.

Section 3 - General Information: Maintenance

Daily Shut-Down Procedure

WARNING

Before attempting to perform any maintenance on

this gun, relieve All Fluid and Air Pressures!

• To relieve fluid and air pressures:

• Turn OFF all air supplies at system except gun

trigger air.

• Trigger the gun until all fluid pressures have been

relieved.

• Turn OFF the gun trigger air at the system.

• Trigger the gun until all trigger air pressure has been

relieved.

Perform Gun maintenance as follows:

1.

Check for leaking seals, p/n GC2540 OR GC2541:

• Turn OFF the gun incoming air by closing gun air

switch.

• Wait approximately 10 - 20 seconds, then turn ON

the incoming air by opening gun air switch.

• Repeat two or three times.

• If any material has been purged from the gun, the

seals are leaking.

• Correct leaks by replacing the seals and re-checking.

2.

Check the material valves, p/n GC2337 for any leaks:

• Turn OFF both material valves.

• Trigger the gun several times.

• Wait approximately 10-20 seconds.

• Trigger the gun several times.

• If additional material is purged, the material valves

are leaking.

• Correct the leaks by taking off black knobs and turning

packing 1/8 in. to 1/4 in. turns at a time until the leak

has stopped. Re-check.

3.

Check side blocks

• Turn OFF the air switch on the gun.

WARNING

Point gun side blocks down, away from all personnel.

Existing fluid pressures could cause material to exit the side blocks with considerable force.

• Take the side blocks off by removing screws.

• Examine the sides of the mixing chamber for scratches

and/or material build-up. Carefully, without scratching

the seal surfaces (sides), remove any accumulated

material. Solvent can be used to wash accumulated

material off of chamber, side blocks, etc. Keep the gun

chamber tilted toward the ground so that solvent does

not run back into gun. Certain solvents will attack

o-rings on chamber shaft causing swelling and deterio-

ration of o-rings.

• Place generous amounts of high quality, white lithium

grease in each side of the gun front housing and on

the side block seals.

• Use correct size drill bit to clean out the mixing cham-

ber exit passage. Use correct size drill bit to clean the

inlet side holes of the mixing chamber taking care not

to scratch the mixing chamber’s polished surfaces.

(refer to the drill chart)

• Re-assemble the side blocks and tighten the screws.

Grease should appear at the tip of the mixing chamber.

DO NOT open the air switch on the gun because this

will purge grease from the gun. The grease should be

allowed to remain in the gun overnight.

WARNING

Before removing the side blocks make certain that both material valves are in the OFF positions and trigger several times to depressurize gun!

If the material valves are on when the side blocks are removed the gun will quickly become encased in urethane!
