AT NO TIME SHOULD THE CASE BE STOCKED BEYOND THE LOAD LINE OR OVER THE FRONT EDGE OF ADJUSTABLE SHELVES.

  • Page 52: Operation Checklist

    OPERATION Hot Gas Defrost Models On hot gas defrost models (optional for parallel compressor operation only) hot gas is routed through the suction line and evaporator coil. It exits the coil through a by-pass around the expansion valve and heat exchanger to return to the liquid line where the condensed liquid is use to feed the other cases on the same parallel unit.

  • Page 53: Troubleshooting

    TROUBLESHOOTING Defrost A quick check of adequate defrost can be made by checking the air movement across the cases. Smoke should move gently from the discharge air honeycomb to the return air grill, but an iced-up coil will be immediately apparent by little or no air current leaving the honeycomb. Case Icing If operation of the case seems normal but the case seems to ice up every three to four weeks, the drain connection to the case and cleanliness of the drain should be checked.
  • Page 54 TROUBLESHOOTING 7. Check for line or compressor leakage. Leakage can be located by heavy deposits of oil on lines or compressor. OK? Go to step 8. If not OK, repair lines or replace compressor and proceed to step 8. 8. Service refrigerant. Dehydrate the refrigerant lines and adjust refrigerant level using the instructions contained in the appropriate chapters of this manual and in the Parallel Compressor Units Installation and Operation Manual, P/N 31E08001.
