The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.
Warnings EQUIPMENT MISUSE HAZARD WARNING Misuse can cause death or serious injury. • Do not operate the unit when fatigued or under the influence of drugs or alcohol. • Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals. • Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.
Warnings Isocyanate Hazard To prevent exposing ISO to moisture: 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.
Warnings Keep Components A and B Separate Changing Materials 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.
Section 1 - Installation: Introduction Introduction The information in this document is intended only to indicate the components and their normal working relationship typical use. Each assembly should be directed by a GlasCraft distributor or made from the GlasCraft Assembly instructions provided. Before operating, maintaining or servicing any GlasCraft system, read and understand all of the technical and safety literature provided with GlasCraft products.
Section 1 - Installation: Standard Equipment Standard Equipment Part Description Number GCP2RX Probler P2 Dispense Gun 313213 User Manual Translations Manual No.
Section 1 - Installation: Equipment Assembly How The Gun Works Piston Lock 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.
Section 1 - Installation: Equipment Assembly GlasCraft Equipment Installing P2 on Other Equipment WARNING Air Hose is ¼ in. NPS 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.
Section 2 - Operation: Start-Up Instructions Refer to specific system user manuals for complete system installation. WARNING If purge air is to be turned OFF, BOTH MATERIAL SHUTOFF VALVES, MUST BE TURNED TO THEIR “OFF” POSITION 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. Pre operation Checklist Check that all fittings are tight and air regulators are turned to “zero pressure”.
Section 2 - Operation: Start-Up Instructions 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. Spray Technique Always operate safely and follow all safety procedures outlined. To achieve the optimum spray pattern for each application, the appropriate mixing chambers are available in seven spray sizes.

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.
Section 3 - General Information: Maintenance • 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). • Re-assemble the side blocks and tighten the screws. Grease should appear at the tip of the mixing cham- ber.
