Warnings 332089B 3 W arnings The f ollowing w ar nings are f or the setup , use, grounding, maintenance , and repair of this equipment. The e xclama- tion point symbol aler ts you to a general w arning and the hazard symbol refers to procedure-specific risk.
Warnings 4 332089B ELECTRIC SHOCK HAZARD This equipment must be grounded. Improper g rounding, setup , or usage of the system can cause elec- tric shock. • T ur n off and disconnect pow er cord before servicing equipment. • Use only grounded electrical outlets.
Isocyanate Conditions 332089B 5 Isocy anate Conditions Material Self-ignition Moisture Sensitivity of Isocy anates ISO will react with moisture (such as humidity) to f or m small, hard, abrasiv e cr ystals, which become sus- pended in the fluid. Eventually a film will f or m on the sur- f ace and the ISO will begin to gel, increasing in viscosity .
Grounding 6 332089B Gr ounding This product must be grounded. In the e vent of an elec- trical shor t circuit, grounding reduces the risk of electr ic shock b y providing an escape wire f or the electr ic cur- rent. Metering valve: attach g round wire from grounding lug to true ear th ground.
Optional Cycle Detection Sensors 332089B 7 Optional Cyc le Detection Sensor s The sensors are magnetic reed s witches and must be connected to an electrical control package. The sensors wires are #24 awg and ha v e 9 f oot (2.7 meters) flying leads. An LED on the sensor illuminates to indicate a change in state.

Rebuild 332089B 19 Reb uild Disassembl y Ref er to F IG . 8 for part references in the f ollowing proce- dure. 1. For models with cyc le detection sensors, discon- nect the electrical power from the cycle detection sensors. Note the position of the sensors , then remov e them b y loosening the set screws and slid- ing them out carefully .
Rebuild 20 332089B 8. Remov e the Scre ws, that hold the Needle Bloc k Assembly to the Inlet Bloc k. The Needle Block Assembly ma y look different than the illustration as it ma y hav e multiple needles . If the needle is a remov ab le #10-32 or Luer Lock type consider removing it to protect it.
