Symbols Warning Symbol Caution Symbol WARNING CAUTION This symbol alerts you to the possibility of serious injury or death if you do not follow the instructions. This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the instructions. WARNING EQUIPMENT MISUSE HAZARD INSTRUCTIONS Equipment misuse can cause the equipment to rupture, malfunction or start unexpectedly and result in serious injury. This equipment is for professional use only.
WARNING PRESSURIZED EQUIPMENT HAZARD Spray from the gun, hose leaks or ruptured components can splash fluid in the eyes or on the skin and cause serious injury. Do not stop or deflect fluid leaks with your hand, body, glove or rag. Follow the Pressure Relief Procedure on page 13 when: you are instructed to relieve pressure; stop spraying; clean, check or service the equipment; and install or clean fluid nozzles. Do not point the spray gun at anyone or at any part of the body.
Selection Charts TERMS: Light Fluid: Up to 18 seconds with No. 2 Zahn cup (20 centipoise) Medium Fluid: 19 to 28 seconds with No. 2 Zahn cup (20–64 centipoise) Heavy Fluid: Greater than 28 seconds with No. 2 Zahn cup (greater than 64 centipoise) -2.8 Volatile Organic Compounds, High-solid Polyurethanes, Heavy Waterborne Enamels HVLP Spray Gun Assemblies Gun Assy.

Air Flow and Atomizing Pressure NOTE: All tests were completed with the 0.055 in. (1.397 mm) nozzle and Part No. 195304 Air Cap, and equivalent gun inlet pressure applied to the atomization and fan ports (or fan adjustment valve fully open on manifold 243950).
Installation The Delta Spray HVLP spray gun was designed to produce the highest quality finish with today’s fluids as well as the Low V.O.C. (volatile organic compound) fluids of tomorrow. This spray gun can spray most coatings or finishes currently being used for automotive, industrial, aerospace, marine, wood, plastic and architectural applications, while easily operating from paint delivery systems such as pressure pots or remote pumps for production line operation.
Installation Mount the Gun To mount the gun on a reciprocating arm [0.5 in. (13 mm) diameter maximum], insert the bar (A) through the hole in the manifold as shown in Fig. 2. Secure the gun to the bar by tightening the mounting screw (B). The tip of the gun should be 6 to 8 inches (150 to 200 mm) from the surface of the object being sprayed. To mount the gun on a stationary support, see Fig. 3. Also refer to the Mounting Hole Layout on page 29. Attach the gun to the support with two M5 x 0.8 capscrews (C).
Setup 1. Connect the Air Line 2. Connect the Fluid Hose NOTE: NOTE: You must install an air pressure regulator (F) on each gun air line to control air pressure to the gun. See Fig. 4. Before connecting the fluid line, blow it out with air and flush it with solvent. Use solvent which is compatible with the fluid to be sprayed. If your regulated air source does not have a filter, install an air filter (G) on each air line to ensure a dry, clean air supply to the gun.
Setup KEY N P R S T 3. Flush the Spray Gun. Cylinder Air Inlet: accepts 1/4 in. (6.3 mm) O.D. tubing Atomization Air Inlet: 1/4–18.6 npsm Fan Air Inlet: 1/4–18.6 npsm Fluid Inlet: 3/8–18.6 npsm Fluid Outlet (circulating gun only): 3/8–18.6 npsm Before putting any paint through the spray gun, flush the gun out with a solvent that is compatible with the fluid to be sprayed, using the lowest possible fluid pressure and a grounded metal container.
Setup 6. Adjust the Spray Pattern WARNING COMPONENT RUPTURE HAZARD Do not exceed the 100 psi (0.7 MPa, 7 bar) maximum fluid and air pressure of this gun. Higher pressures can cause parts to rupture and result in serious injury. Follow these steps to establish the correct fluid flow and air flow: A. Adjust the fluid flow using the fluid pressure regulator (L) installed in the gun fluid line. Typical industrial flow rates will vary with regulator pressures from 5 to 30 psi (34 to 210 kPa, 0.3 to 2.1 bar).
Setup C. Test the spray pattern and atomization while keeping the gun a consistent distance, about 6 to 8 inches (150 to 200 mm), from the test piece. D. If the spray pattern is too wide, reduce the fan air pressure (or slightly close the fan adjustment valve on manifold 243950). NOTE: Reducing the fan air pressure to 0 psi (or fully closing the fan adjustment valve) will produce a round pattern. E. Check the atomization quality again.

Operation Pressure Relief Procedure WARNING PRESSURIZED EQUIPMENT HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you: are instructed to relieve the pressure, stop spraying, check or service any of the system equipment, or install or clean the spray nozzle. 1.
Daily Gun Care, Flushing, and Cleaning WARNING CAUTION PRESSURIZED EQUIPMENT HAZARD To reduce the risk of a serious injury whenever you are instructed to relieve pressure, follow the Pressure Relief Procedure on page 13. Clean all parts with a non-conductive solvent, compatible with the fluid being sprayed. Conductive solvents can cause the gun to malfunction.
Daily Gun Care, Flushing, and Cleaning WARNING PRESSURIZED EQUIPMENT HAZARD To reduce the risk of a serious injury whenever you are instructed to relieve pressure, follow the Pressure Relief Procedure on page 13. 1. Relieve the pressure. 2. Shut off the gun fan and atomizing air. Fig. 11 02007 3. Supply a compatible solvent to the gun fluid inlet. 11. With the gun pointed down, clean the front of the gun, using the soft-bristle brush and solvent. 4.
Troubleshooting WARNING PRESSURIZED EQUIPMENT HAZARD To reduce the risk of a serious injury, follow the Pressure Relief Procedure on page 13 before checking or repairing any part of the gun or system. NOTE: Check all possible remedies in the troubleshooting charts before disassembling the gun. Some improper patterns are caused by the improper balance between air and fluid. Refer to Spray Pattern Troubleshooting, on page 19.
Troubleshooting General Troubleshooting (continued) Problem Cause Solution Fluid needle will not trigger. Loose or missing fluid needle stop (29) or setscrew (30). Replace stop (29) or tighten setscrew (30). Air leaking around piston (3). Replace o-ring (8) or piston (3). Swollen piston o-ring (8). Replace o-ring (8). Do not immerse piston in solvent. Insufficient air pressure on the trigger. Increase the air pressure or clean the air line. Fluid does not shut off.
