[. . . ] Allow material to flow out of the coupling block until all spitting of air stops and all traces of residual material have disappeared. Close the manual valves and flush any residual chemical from the outside of the coupling block (see gun operating manual). Slowly increase the air pressure and check all fittings for signs of hydraulic and chemical leakage. (See the gun operating manual. ) IMPORTANT: After the proportioning system has been brought up to operating pressure and all hose connections are tight and free of leaks, wrap together the hoses and electrical wires around the area of the rubber isolators with a liberal amount of duct tape to form a compact bundle. If a scuff jacket is being used, pull it over the bundle and secure with tape. 9/1/04 21 Model FF-1600 Proportioning Unit OPERATION Daily Start-up Procedure IMPORTANT: The Daily Start-up Procedures describe normal operation, assume that all calibrations have been properly executed, and that the heating system is not up to operating temperature. Check the condition of the air system and isocyanate lubricant cup. Determine that the supply system is at the proper temperature as recommended by the system supplier, that the individual chemicals are properly mixed within their drums, and that the moisture protection system is properly set for operation. The packing nuts on the iso and resin pumps are adjustable and will require periodic tightening. The iso packing will require tightening when the pump lubricant requires frequent changing. Check the inlet screens and service as required. Turn on the main air supply to the transfer pumps. Uncoil the heated hose assemblies. 2. 3. 4. 8. WARNING: UNCOIL THE HOSES BEFORE SWITCHING ON THE HOSE HEAT CIRCUIT BREAKER TO PREVENT OVERHEATING THE HOSE ASSEMBLIES AND CREATING HOT SPOTS WITHIN THEM. 9. On manual hose heat units, turn the hose heat power control full counterclockwise. 10. Switch ON the hose heat circuit breaker. On digital hose heat units, adjust the digital temperature controller to the desired temperature. NOTE: As the hoses warm up, the amperage will drop slightly and will not need readjusting. 12. On manual hose heat units, adjust the hose heat power control clockwise to 45-50 amps for quick warm-up. (Do not exceed 50 amps. ) Check the hose thermometer for proper spray temperature. (Do not exceed 170°F/76°C. ) Readjust the power control as necessary to maintain temperature. Switch ON the primary heater circuit breaker. The amber pilot light should be on and then cycle to off as the heater comes up to temperature. Set the desired temperature of the heater by making small adjustments to the temperature control screw (clockwise to increase, counterclockwise to decrease) and allowing the heater to stabilize in between. 22 17942-1, Issue 8 Operating Manual Normal Operating Procedures WARNING: TO PREVENT EXCESSIVE PRESSURE BUILD-UP IN THE HEATED HOSES, ALWAYS BRING THE HOSES AND PRIMARY HEATER UP TO OPERATING TEMPERATURE BEFORE TURNING ON THE PUMP SWITCH. 14. One of the amber directional indicator lights should be ON and the proportioning pumps should move a short distance and pressurize. [. . . ] Switch OFF the pump switch and disconnect the air from the proportioning unit. Remove the pump lubricant from the cup by dipping a dry rag into the cup to absorb the contaminated liquid. Remove any hardened material from the shaft, taking care not to scratch the shaft. Fill the lubricant cup with Gusmer pump lubricant to about 1/4 inch below the top. 2. 3. 9/1/04 35 Model FF-1600 Proportioning Unit APPENDIX TABLE 1. [. . . ]
