3. Heaters, if used: refer to Viscon HP Heater manual, 309524. 4. Air compressor: follow manufacturer’s recommendations. 5. Spray gun: ground through connection to a properly grounded fluid hose and pump. 6. Fluid supply container: follow your local code. 7. Object being sprayed: follow your local code. 8. Solvent pails used when flushing: follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity. 9. To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the gun. 307932 5 Installation Supplied Components Refer to Fig. 2 for a typical installation of an airless system. WARNING A red-handled bleed-type master air valve (14) and a fluid drain valve (7) are supplied in your system. These accessories help reduce the risk of serious injury, including fluid injection and splashing of fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump. The red-handled bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump. The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun. Triggering the gun to relieve pressure may not be sufficient. . The red-handled bleed-type master air valve (14) is required in your system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING above). Be sure the bleed valve is easily accessible from the pump, and is located downstream from the air regulator. . The air regulator (8) controls pump speed and outlet pressure by adjusting the air pressure to the pump. Locate the regulator close to the pump, but upstream from the red-handled bleed-type master air valve (14). . The air manifold (15) has a swivel air inlet. It mounts to the cart, and provides ports for connecting lines to air-powered accessories. . The fluid filter (4) includes a 60 mesh (250 micron) stainless steel element to filter particles from the fluid as it leaves the pump. . The fluid drain valve (7) is required in your system to relieve fluid pressure in the hose and gun (see the WARNING above). . The suction hose (24) and tube (25) allow the pump to draw fluid from a 200 liter (55 gallon) drum. System Accessories Air and Fluid Hoses Be sure all air hoses (A) and fluid hoses (G) are properly sized and pressure-rated for your system. Use only electrically conductive hoses. 1. Connect one end of the fluid line (G) to the filter outlet swivel. Connect a fluid hose to each gun (H). Install a fluid shutoff valve (J) at each gun drop. Do not install the spray tip in the gun yet. 2. Close the red-handled bleed valve (14) and air regulator (8). Connect the air hose (A) to the swivel inlet of the air manifold (15). Air Line Accessories 1. Install an air line filter (B) in the main air line, to remove harmful dirt and moisture from the compressed air supply. 2. Install a second bleed valve (C) in the main air line, to isolate the accessories for servicing. 3. Install a drain valve (D) at the bottom of each air line drop, to drain off moisture. 4. To provide automatic lubrication of the air motor, install an air line lubricator (E) downstream from the red-handled bleed-type master air valve (14). 5. Install a pump runaway valve (F). The runaway valve will automatically shut off the air to the pump if the pump starts running too fast. A pump that runs too fast can be seriously damaged. 6 307932 Installation KEY SUPPLIED COMPONENTS 1 Pump 2 Pump Wall Bracket 4 Fluid Filter 7 Fluid Drain Valve (required) 8 Pump Air Regulator 14 Red Handled Bleed-Type Master Air Valve (required, for pump) 15 Air Manifold 24 Suction Hose 25 Suction Tube 45 Ground Wire (required; see page 5 for installation instructions) B C ACCESSORIES YOU MUST SUPPLY A Electrically Conductive Air Hose B Air Line Filter C Bleed-Type Master Air Valve (for accessories) D Air Line Drain Valve E Air Line Lubricator F Pump Runaway Valve G Electrically Conductive Fluid Line H Airless Spray Gun J Fluid Shutoff Valve E A 14 8 G H 15 45 1 2 7 4 24 25 F D G G J JH Model 245187 Shown 01763A Fig. 2 307932 7 Installation Models 245187 and 253697 (for Ambient Temperature Spray Applications) NOTE: Refer to page 10 to convert Pump Model 245187 or 253697 to a heated system. 1. Mount the pump wall bracket (2) 5 ft (1.5 m) above the floor. Be sure the wall is strong enough to support the weight of the pump and accessories, fluid, hoses, and stress caused during pump operation. Refer to Mounting Hole Layout on page 20. 2.
