Material Self-Ignition

Warnings

•

•

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.

Section 1 - Installation: Equipment Assembly

How The Gun Works

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 towards 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.

The proper alignment of the orifices is determined by the setting of the adjustment nut, located on the piston 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 adjustment. (SEE MAINTENANCE SECTION)

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.

Piston Lock

Engage piston lock whenever you stop spraying, to avoid accidental triggering.

Always use piston lock in conjunction with fluid ball valves to avoid accidental triggering.

WARNING

Read warnings, page 3.

To engage Piston lock:

push knob in and turn clockwise.

If engaged, gun will not actuate.

r_257826_313266_1_2b

To disengage piston lock:

push knob in and turn counterclockwise until it pops out. There will be a gap between knob and gun body.

r_257826_313266_1_1b

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:

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 AND PISTON-LOCK ENGAGED 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 anytime.

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, recommendations of the chemical suppliers, and the laws in the area where the equipment is being used.

Operating Requirements

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 and piston lock DISENGAGED during dispensing and must be FULLY CLOSED and piston lock

ENGAGED during service or extended shut-down periods.

WARNING

• 8-10 CFM at 90-110 psi (0.62-0.76 MPa,

6.2-7.6 bar)

• MAXIMUM Static Fluid Pressure - 3500 psi (24.1

MPa, 241 bar)

BOTH MATERIAL SHUT-OFF VALVES, MUST BE

TURNED TO THEIR “OFF” POSITION AND ALL FLUID

PRESSURE RELIEVED BEFORE REMOVING SIDE

BLOCK SCREWS!!

Failure to follow this procedure will possibly result in the gun head becoming encased with mixed product.

WARNING

The GlasCraft Probler P2 Gun is designed and manufactured to operate at a maximum static fluid pressure not to exceed 3500 psi (24.1 MPa, 241 bar). When attached to a GlasCraft proportioning system, this pressure will not be exceeded. However, if the GlasCraft Probler P2 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.

ti19823a

ON OFF

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

11

Section 2 - Operation: Start-Up Instructions

Spray Technique

Always operate safely and follow all safety procedures outlined.

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.

To achieve the optimum spray pattern for each application, the appropriate mixing chambers are available in seven spray sizes.

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.

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 manufacturer’s data specification sheets for their recommended spray temperatures.

Under most circumstances, both components will be used at identical temperatures.

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.

•

•

•

•

Disengage piston lock.

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 loosening the set screw and

removing red or blue handle. Turn the valve packing

nut clockwise in 1/8-turn increments until leak is

corrected. Re-check.

•

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 (34) are leaking, or o-ring (35).

• Correct leaks by replacing the seals or o-rings and

re-checking.

1/8 ti19008a

3. Check side blocks

•

Turn OFF the air switch on the gun.

WARNING

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

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

WARNING

15

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.

•

Use correct size drill bit to clean out the mixing chamber exit passage. Use correct size drill bit to

clean the inlet side holes of the mixing chamber tak- ing care not to scratch the mixing chamber’s polished surfaces (refer to the drill chart).

ti21611a

•

Examine the sides of the mixing chamber for scratch-

es 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 deterioration of o-rings.

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

Grease should appear at the tip of the mixing chamber.

•

Place generous amounts of high quality, white lithium grease (Part No. 117773) in each side of the gun

front housing and on the side block seals.

16

ti21611a

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.


Daily Shut-Down

It is recommended that the following service be performed on a daily basis.

1.

4.

Read each procedure entirely before beginning and refer to the illustrations as needed.

2. become accessible.

3.

Flush and clean all chambers and passages as they

Clean all parts before assembly.

Replace all o-rings and seals with new parts from the appropriate kit.

5. Inspect all parts for wear or damage and replace as required with new genuine GlasCraft replacement parts from your authorized GlasCraft distributor.

6. Inspect all threads for wear or damage and replace as required.

1. Clean the gun using a brush and an appropriate clean solvent.

2. Inspect the side block seals making certain they are clean and free of scratches, nicks or foreign material.

Clean and replace as required.

3. Remove, clean or replace the filter screen.

4. Maintain a reasonable stock level of “wear” items such as seals and o-rings. (see Service & Repair Parts Kits listed in Parts & Illustrations section.)

5. Grease gun daily to prevent 2 component curing and keep fluid passages clean. Purge air carries grease mist through air chamber and impingement ports then out the mix chamber nozzle, coating all surfaces. Use

Part No. 117773 grease.

7. Tighten all threaded parts securely, but not excessively, upon assembly.

8. Lightly lubricate all o-rings and threads with grease (Part No. 118665).

9. Check all springs for resilience. They should return quickly to their original (new) length.

Piston Lock Adjustment and Installation

Procedure

5. Remove one of the side block seal housings, from side block. Leave the seal (34) in housing and rinse with suitable solvent.

The P2 gun piston throw is factory set and as a rule, should not require adjustment. The piston throw refers to how far back the air piston will travel when the gun is triggered.

Proper throw adjustment will align the mixing chamber side ports with the side block seal thru port.

8. If the impingement port is not fully visible through the side seal housing turn the trigger-air off and trigger the gun to relieve pressure. Use a 9/16 in. open-end wrench to adjust the adjustment nut in the appropriate direction. Repeat steps 7 and 8 until it is adjusted properly.

9. If the impingement port on the mix chamber is fully visible through the side seal housing (either on center or slightly forward), the piston lock adjustment nut is properly aligned.

Non-permanent thread locker can be applied to the adjustment nut if necessary.

10. Reassemble the gun.
