Use any of the three mounting hole groupings in the bracket. See Wall Mounting Bracket Diagram, page 20. 5. Bolt the bracket securely to the wall using bolts and washers designed to hold in the wall’s construction. 6. Attach the pump assembly to the mounting bracket. 7. Connect air and fluid hoses. Flush Before Using Equipment The equipment was tested with lightweight oil, which is left in the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the equipment with a compatible solvent before using the equipment. See your respective pump manual. See Related Manuals on page 3. Integrated Air Control Module See FIG. 1. The integrated air control module (C) is included with all packages. It includes the following (see 311239 for detailed information): • Bleed-type master air valve (D): required in your system to relieve air trapped between it and the air motor when the valve is closed. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts. • Pump air regulator (E): adjusts air pressure to the motor and fluid outlet pressure of pump. View the gauge (F) to read air pressure. • Safety relief valve (G): automatically opens to relieve air pressure, to prevent pump overpressurization. • Air filter (H): removes harmful contaminants from entering the air control module and air motor. 312585E Installation TI11380A A B C EH J K LM N P R S U T Detail of Integrated Air Control Module (C) D F G TI8322C FIG. 1: Typical Installation (Cart Mount Package Shown) A Displacement Pump N Portable Cart B Air Motor P Fluid Suction Hose C Integrated Air Control Module (includes items D-H) R Fluid Suction Tube and Strainer D Bleed-type Master Air Valve (required) S Fluid Spray Hose E Pump Air Regulator T Spray Gun and Wand F Air Pressure Gauge U Ground Wire (required) G Safety Relief Valve H Air Filter (hidden) J Air Inlet K Air Supply Line L Air Line Shutoff Valve M Air Line Filter 312585E Installation Grounding Although water generally provides a natural electrical ground, the following equipment must be grounded if the cleaning chemicals are volatile. The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit. When cleaning in enclosed areas, such as storage tanks, locate the pump and air compressor outside the area and well away from it. Provide adequate ventilation. If the area you are cleaning has stored flammable materials. take appropriate precautions to avoid static sparking. Consult your local codes. Pump: use supplied ground wire and clamp. See FIG. 2. Use the ground screw (GS) and lockwasher (LW) to attach the ground wire (U) at the rear of the air motor. Tighten the screw securely. Connect the other end of the ground wire to a true earth ground. GS, LW TI8250A FIG. 2. Ground Wire U Air and fluid hoses: use only electrically conductive hoses. Air compressor: follow manufacturer’s recommendations. Spray gun / Dispense valve: ground through connection to a properly grounded fluid hose and pump. Fluid supply container: follow local code. Object being sprayed: follow local code. Solvent pails used when flushing: follow local code. Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity. To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray gun/dispense valve firmly to the side of a grounded metal pail, then trigger the gun/valve. 312585E Operation Pressure Relief Procedure Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts. 1. Engage the trigger lock. 2. Close the bleed-type master air valve to shutoff the pump. 3. Disengage the trigger lock. 4. Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to relieve pressure. 5. Engage the trigger lock. 6. Open all fluid drain valves in the system, having a waste container ready to catch drainage. Leave the drain valve(s) open until you are ready to spray again. 7. If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen the tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Clear the hose or tip obstruction. Operation Cleaning Solutions Prepare the cleaning solution according to the manufacturer’s instruc...
