Install 1/4 in. tube fitting into the cylinder (CYL) air port. 2. Install plugs into the atomization (ATOM) air port and the fan (FAN) air port. CYL ATOM Ground them according to the manufacturer recommendations. Ground Air, Fluid, and Hydraulic Hoses Connected to Pump Use only electrically conductive hoses with a maximum of 100 ft (30.5 m) combined hose length to ensure grounding continuity. Check the electrical resistance of your air and fluid hoses at least once a week. If the total resistance to ground exceeds 25 megohms, replace the hose immediately. Use a meter that is capable of measuring resistance at this level. FAN TI8225a FIG. 2: Air Fittings Ground System Ground Spray Gun Ground the spray gun by connecting it to a properly grounded fluid hose and pump. Ground Fluid Supply Container Ground the fluid supply container according to local code. The following grounding instructions are minimum requirements for a system. Your system may include other equipment or objects that must be grounded. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Your system must be connected to a true earth ground. Ground Pump Ground the pump by connecting a ground wire and clamp between the fluid supply and a true earth ground as instructed in your separate pump instruction manual. 6 Ground Object Being Sprayed Ground the object being sprayed according to local code. Ground Solvent Pails Ground all solvent pails that are used with flushing according to local code. Use only metal pails, which are conductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity. 311053H Installation Mount Gun Stationary Support Mount All Manifolds Reciprocating Arm Rod Mount To mount the gun on a stationary support (refer to FIG. 4. and Mounting Hole Layout, page 28): Manifolds 241161 and 241162 To mount the gun on a reciprocating arm rod [0.5 in. (13 mm) diameter maximum]: 1. Insert the mounting bar (A) through the hole in the manifold as shown in FIG. 3. Use the 1/8 in. alignment pin (P) to assist in orienting the gun. 1. Attach the gun to the support with two M5 x 0.8 capscrews (C). The screws must be long enough to engage the threaded holes in the gun manifold to a depth of 1/4 in. (6 mm). 2. Ensure the tip of the gun is 8 to 10 in. (150 to 200 mm) from the surface of the object being sprayed. 2. Secure the gun to the bar by tightening the mounting screw (B). 3. Ensure the tip of the gun is 8 to 10 in. (150 to 200 mm) from the surface of the object being sprayed. B P C TI8112a FIG. 4: Stationary Support Mount A TI8111a FIG. 3: Reciprocating Arm Mount 311053H 7 Setup Setup Air Line and Accessory Recommendations Fluid Line and Accessory Recommendations 1. Install an air pressure regulator on the gun cylinder air supply line. A minimum of 70 psi (0.49 MPa, 4.9 bar) air pressure must be supplied to the cylinder for proper operation. Air pressure opens the valve, a spring closes the valve. A three-way air valve, which exhausts cylinder air, is required. 2. Install a bleed-type air shutoff valve on the main air line. Install an additional bleed-type valve on each pump air supply line, downstream of the pump air regulator, to relieve air trapped between this valve and the pump after the air regulator is shut off. The bleed-type air shutoff valve is required in your system to relieve air trapped between this valve and the pump after the air regulator is closed. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury. 3. Install a bleed-type air shutoff valve on the gun air cylinder supply line, downstream of the air regulator, to shut off air to the gun cylinder. Connect the air supply line to the gun cylinder air inlet (C). See Fig. 4. The cylinder air inlet accepts 1/4 in. (6.3 mm) O.D. tubing. • A fluid drain valve(s) is required in your system to assist in relieving fluid pressure in the displacement pump, hose and gun; triggering the gun to relieve pressure may not be sufficient. • A fluid pressure regulator must be installed in the system if the pump's maximum working pressure exceeds the gun's maximum fluid working pressure (see the front cover). 1. Install a fluid filter and drain valve(s) close to the pump's fluid outlet. 2. Install a fluid pressure regulator to control fluid pressure to the gun. Some applications require fine-tuned control of fluid pressure. You can control fluid pressure more accurately with a fluid pressure regulator than by regulating the air pressure to the pump. 3. Install a fluid shutoff valve to shut off the fluid supply to the gun. 4. For paint spray applications, install an in-line fluid filter, part no. 210500, on the gun fluid inlet (F) to avoid clogging the spray tip with particles from the fluid. See Fig. 4. 5. Connect the electrically conductive fluid hose to the gun fluid inlet (F) or optional in-line filter. 8 311053H Setup Manifolds 288219 and 288220 Manifold 244930 6. In a circulating system, connect an electrically conductive fluid hose to the gun fluid outlet (G). 7. This manifold is equipped with passages for circulating water to maintain the temperature of the gun. Ports provided are: In a non-circulating system, remove the gun fluid outlet fitting (G) and plug the outlet port with the pipe plug (109) supplied. KEY C Cylinder Air Inlet: accepts 1/4 in. (6.3 mm) O.D. tubing F Fluid Inlet: 1/4-18 nptf or #5 JIC (1/2-20 unf) G Fluid Outlet (circulating gun only): 1/4-18 nptf or #5 JIC (1/2-20 unf) • • • Side water inlet, 1/4 npt(f) Top water outlets, 1/8 npt(f) Side RTD sensor, 1/8 npt(f) See Accessories, page 26, for available fittings and sensors. KEY L Water Outlet: 1/8 npt(f) M Air Inlet (to open valve): 1/8 npt(f) N Fluid Inlet: 3/8(f) P Water Inlet: 1/4 npt(f) G (or F) C F (or G) M FAN ATOM CYL L TI8113a FIG. 5 N L TI8115a P TI8116a FIG. 6 311053H 9 Setup Flush Spray Gun Adjust Spray Pattern Before running any paint through the spray gun: 1. To adjust the spray pattern direction with fan tips, orient the slot in the tip horizontally for a horizontal pattern and vertically for a vertical pattern. See Fig. 7. 1. Flush the gun with a solvent that is compatible with the fluid to be sprayed, using the lowest possible fluid pressure and grounded metal container. Install Spray Tip 2. Start the pump. Adjust the fluid pressure until the spray is completely atomized. Use the lowest pressure necessary to get the desired results. Higher pressure may not improve the spray pattern and will cause premature tip wear and pump wear. 1. Perform Pressure Relief Procedure; see page 11. 3. The spray tip orifice and spray pattern angle determines the coverage and size of pattern. When more coverage is needed, follow the Pressure Relief Procedure, page 11, and install a larger spray tip rather than increasing fluid pressure. 2. Perform Pressure Relief Procedure; see page 11. 2. Install the spray tip (H) and the gasket (J) in the tip retainer nut (K). Screw the assembly firmly onto the gun. Tighten the assembly with a wrench. See FIG. 7. K Vertical Pattern J H TI8577a TI8170a FIG. 7: Install Spray Tip TI8196a Gaskets are included with Streaming Tips 270XXX or Fan Tips 182XXX. Horizontal Pattern FIG. 8: Spray Pattern Adjust a Streaming Tip Select a tip that will supply a stream at the required flow rate at the lowest pressure. 10 311053H Operation Operation Pressure Relief Procedure Apply the Fluid 1. Shut off the power to the pump. Adjust the system control device, if it is automatic, so the gun starts spraying just before meeting the workpiece and stops as soon as the workpiece has passed. Keep the gun a consistent distance, 8 to 10 in. (200 to 250 mm), from the surface of the object being sprayed. 2. Turn off the air and fluid supply to the gun. To achieve best results when applying fluid: 3. Close the bleed-type master air valve (required in the system). • Keep gun perpendicular and 8 to 10 inches (200 to 250 mm) from object being sprayed. 4. Trigger the gun into a grounded metal waste container to relieve the fluid pressure. • Use smooth, parallel strokes across surface to be sprayed with 50% overlap. See FIG. 10. Incorrect TI8174a FIG. 9: Pressure Relief 5. Open the pump drain valve (required in the system) to help relieve fluid pressure in the displacement pump. In addition, open the drain valve connected to the fluid pressure gauge (in a system with fluid regulation) to help relieve fluid pressure in the hose and gun. Triggering the gun to relieve pressure may not be sufficient. Have a container ready to catch the drainage. TI8098a Correct 6. Leave the drain valve(s) open until you are ready to spray again. 7. If you suspect that the spray tip or hose is completely clogged or that pressure has not been fully relieved after following the steps above, very slowly loosen the hose end coupling and relieve pressure gradually, then loosen the coupling completely. Now clear the tip or hose obstruction. TI8099a FIG. 10: Correct Spray Method 311053H 11 Daily Gun Care Daily Gun Care CAUTION Methylene chloride with formic or propionic acid is not recommended as a flushing or cleaning solvent with this gun as it will damage aluminum and nylon components.
