Lubrication system setup Component A (ISO) Pump: Fill ISO lube reservoir (LR) with Graco Throat Seal Liquid (TSL), Part No. See page 17. a. Lift the lubricant reservoir (LR) out of the bracket (RB) and remove the container from the cap. Do not disconnect wire or spray without whip hose. ST RB LR c. Fluid supply containers: follow your local code. ti7738a d. Object being sprayed: follow your local code. b. Fill with fresh lubricant. Thread the reservoir onto the cap assembly and place it in the bracket (RB). e. Solvent pails used when flushing: follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity. c. Push the larger diameter supply tube (ST) approximately 1/3 of the way into the reservoir. d. Push the smaller diameter return tube (RT) into the reservoir until it reaches the bottom. f. To maintain grounding continuity when flushing or relieving pressure, hold a metal part of spray gun firmly to the side of a grounded metal pail, then trigger gun. Important: The return tube (RT) must reach the bottom of the reservoir, to ensure that isocyanate crystals will settle to the bottom and not be siphoned into the supply tube (ST) and returned to the pump. 13. Check hydraulic fluid level Hydraulic reservoir is filled at the factory. Check fluid level before operating the first time, and weekly thereafter. See Maintenance, page 33. e. The lubrication system is ready for operation. No priming is required. 311299E 21 Startup Startup WARNING c. SA SB Do not operate Reactor without all covers and shrouds in place. e. 1. Fluid Temperature Sensor (FTS) Calibration Calibrate the FTS ONLY at initial startup (the first time the unit is operated) and any time the hose length changes. ti7739a a. f. Before turning on the unit, ensure all hoses and cables are properly connected. To ensure that the FTS in the hose is at the same temperature as the heaters, keep heat off and store the hose FTS near the machine for several minutes. Start feed pumps. c. While holding down the temperature unit button (Fahrenheit - "F" or Celsius "C") turn the Reactor main power ON. Hold the temperature unit button until temperature is shown on the display. The fluid temperature sensor is now correctly calibrated. ti7736a Do not mix components A and B during startup. Always provide two grounded waste containers to keep component A and component B fluids separate. h. 1. Load fluid with feed pumps The Reactor is tested with oil at the factory. Open fluid valves A and B until clean, air-free fluid comes from valves. Check that inlet screens are clean before daily startup, page 33. ti2484a 311299E Startup 2. Set temperatures d. To set A heat zone target temperaor until display ture, press shows desired temperature. Repeat for A B For B and zones. zone only, if FTS is disconnected at startup, display will show hose current (0A).
