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.

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 crystal lization varies depending on the blend of ISO, the humidity, and the temperature.

5

Material Self-ignition

Some materials may become self-igniting if applied to thickly. Read material manufacturer’s warnings and material MSDS.

Keep Components A and B

Separate

Warnings

•

Changing Materials

When changing materials, flush the equipment mul tiple 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.

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 hous ing, side seal assembly, check valve cartridge, and mix chamber are marked on the A side.

Section 1 - Installation: Equipment Assembly

How The Gun Works Piston Lock

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

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 orifices are aligned with the orifices in both, the side block seal and check valve assem blies.

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.

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 assem blies 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 in side 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 cham ber until the air switch is pulled up to shut-off all air to the gun; or until the trigger is pulled again.

r_257826_313266_1_2b

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.

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:

•

•

Push in piston lock, see Engage piston lock .

Close ball valves A and B.

WARNING

Relieve ALL system fluid and air pressure according to manufacturer’s instructions.

Section 2 - Operation: Start-Up Instructions

Refer to specific system user manuals for complete system installation.

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 equip ment, 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

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

6.2-7.6 bar)

• MAXIMUM Static Fluid Pressure - 3200 psi

(22 MPa, 220 bar)

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 dispens ing and must be FULLY CLOSED and piston lock

ENGAGED during service or extended shut-down periods.

WARNING

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 Auto Probler P2 Gun is designed and manu factured to operate at a maximum static fluid pressure not to exceed 3200 psi (22 MPa, 220 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 maxi mum 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

11

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

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.(15.25 m), 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 round and six flat spray sizes.

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 specifi cation sheets for their recommended spray temperatures.

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

The gun air switch assembly MUST BE OPENED (down position) prior to spraying to provide air for piston operation and purge air when the piston is released.

When spraying, the gun piston may be activated continuously, or deactivated 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.

been relieved.

Perform Gun maintenance as follows:

1. Check for leaking seals (Ref. 27):

•

•

Engage piston lock.

Turn OFF the gun incoming air by closing gun air

switch.

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 (Ref. 27) are leaking, or o-ring (Ref. 28).

Correct leaks by replacing the seals or o-rings and

re-checking.

•

•

•

•

Disengage piston lock.

Activate and deactivate the gun several times.

Wait approximately 10-20 seconds.

Activate and deactivate the gun several times.

• If additional material is purged, the material valves

are leaking.

• Correct the leaks by taking off black knobs and turn-

ing 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

Before removing the side blocks make certain that both material valves are in the OFF positions! Also activate and activate several times to relieve fluid pressure in the gun.

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

WARNING

Point gun side blocks down, away from all personnel.

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

15


• 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 in this manual).

r_gcp4ra_313267_1_6e

• 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 cham-

ber.

• Place generous amounts of high quality, white lithium

grease in each side of the gun front housing and on

the side block seals.

r_gcp4ra_313267_1_6e

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.

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.

Determine if the piston throw is correct:

1. Follow the pressure relief procedure on page 15 and disconnect material hoses from the gun.

2. Turn the material ball valves to the OFF position.

6. Place the side seal housing in the gun head so the face of the seal sets against the mix chamber.

WARNING


7. Turn the gun trigger air supply on , then trigger the gun.

The purge air will not shut off with the side block removed.

3. Verify that the piston lock cap has been tightened and fully threaded into the gun.

4. Remove the side blocks.

r_gcp4ra_313267_1_6e

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.

19

Before each use: Verify that the piston lock assembly is installed and working properly.

•

•

•

•
