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. D Do not point the gun at anyone or at any part of the body. D Do not stop or deflect leaks with your hand, body, glove or rag. D Follow the Pressure Relief Procedure on page 7 whenever you: are instructed to relieve pressure; stop spraying; clean, check, or service the equipment; and install or clean the spray tip.
Installation General Information NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawing. Prepare the Operator All persons who operate the equipment must be trained in the safe, efficient operation of all system components as well as the proper handling of all fluids. All operators must thoroughly read all instruction manuals, tags, and labels before operating the equipment.
Installation 8. Using two people, lift the heater (1) onto the bracket (5) so the two screw heads (E) slide into the slots. Have one person hold the heater in place while the other installs the remaining two screws (supplied with the heater) through the bracket and into the bottom mounting posts. Tighten all four screws. 9. Connect the free end of the heater supply hose (2) to the swivel (A) at the pump fluid outlet. Tighten securely. 10.
Installation Connect the Fluid Lines 3. Air and fluid hoses: use only electrically conductive hoses. Connect a 1 to 3 ft (0.3 to 0.9 m) hose to the tee at the outlet of the fluid filter, to isolate the pump module from the main fluid line. Connect the other end of the hose to the main fluid line. 4. Air compressor: follow manufacturer’s recommendations. 5. Spray gun: ground through connection to a properly grounded fluid hose and pump. Grounding 6. Agitator: use a ground wire and clamp (Y). See Fig. 3.
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: D D D D are instructed to relieve the pressure, stop spraying, check or service any of the system equipment, or install or clean the spray nozzle.
Operation Heater Operation Before operating the heater, read the heater instruction manual 309524 which is supplied. Prime the Pump 1. Disconnect the electric power to the heater before priming the pump. 2. Open the fluid shutoff valve (L). 3. Open the back pressure regulator (M). Turn the 3-way recirculation valve (J) to the circulation position. CAUTION Do not allow the pump to run dry. It will quickly accelerate to a high speed, causing damage.
