  • Page 36: Start-Up And Operation

    P18AL Service Manual START-UP AND OPERATION 5. Start-Up and Operation Refrigeration System Review The refrigeration system uses anhydrous ammonia (R-717) refrigerant. Following the piping schematic (Figure 3-2 or 3-3), you will see that during the machine’s freeze cycle, the compressor discharge gas goes through the oil separator to remove any oil present in the discharge gas and return the oil to the compressor crankcase.

  • Page 37: Refrigerant Charge

    P18AL Service Manual STAR-UP AND OPERATION Refrigerant Charge Prior to charging the machine with anhydrous ammonia (R-717) make sure the system is leak tight and free of non-condensables or other contaminants. The machine will require a full charge of pure anhydrous ammonia. Make sure it is from a reputable supplier who can and will furnish quality ammonia of Refrigeration or Federal Technical grade.

  • Page 38: Charging From Cylinders (Dedicated High Side Only)

    P18AL Service Manual START-UP AND OPERATION Charging From Cylinders (dedicated high side only). The machine may also be charged from refrigerant cylinders. To charge from cylinders, the compressor will have to operate to transfer the ammonia from the freezer to the receiver. Again, make sure all the necessary valves are opened for operation and the compressor crankcase heater has been energized for a minimum of four (4) hours.
  • Page 39 P18AL Service Manual STAR-UP AND OPERATION Transferring refrigerant from a refrigeration system into a cylinder can be very dangerous and is not recommended. As the machine is being charged, continually observe the following operating characteristics: a) Discharge pressure - 175 psi to 200 psi maximum b) Compressor oil pressure - Mycom W-Series,18-27 psi, Vilter 450-Series, 35-50 psi.
  • Page 40 P18AL Service Manual START-UP AND OPERATION Start-up CAUTION The crankcase heater should be energized for a MINIMUM of 4 hours and the crankcase must be free of liquid before attempting to operate the compressor.

  • Page 58 P18AL Service Manual TROUBLESHOOTING Symptom: Machine Stopped Possible Cause Possible Remedy Power failure or interruption Check fused disconnect or circuit breaker supplying power to the machine. If power has been off, make sure the crankcase heater is energized and there is no liquid refrigerant in the compressor crankcase prior to restarting the compressor.
  • Page 59 P18AL Service Manual TROUBLESHOOTING Symptom: Freeze-up due to extended freeze period Possible Cause Possible Remedy Freeze timer (T2) set to long Adjust timer or replace if defective. See FIGURE 9-2. Freezer pressure switch (FPS) set too low or defective Adjust switch or replace if defective. (optional) Water tank drain valve, make-up water float valve or flushing Close, repair, or replace valve as needed.
  • Page 60 P18AL Service Manual TROUBLESHOOTING Symptom: Low ice capacity. Suspicions of low ice capacity should be confirmed by accurate calculations of actual ice product. Significant losses can occur due to melting and off fall through augers and other ice handling equipment. Time the total cycle (freeze time + thaw time).
  • Page 61 P18AL Service Manual TROUBLESHOOTING Symptom: Poor ice quality Possible Cause Possible Remedy Excessive concentration of solids in the water tank usually Perform a cleaning procedure as well as removing the freezer indicated by a build-up of mineral deposit on the sides and cover and cleaning the water distributors.
  • Page 62 P18AL Service Manual TROUBLESHOOTING Symptom: High suction pressure (check gage accuracy) Possible Cause Possible Remedy Compressor running unloaded or not pumping efficiently Check compressor motor amp. If the compressor is running unloaded, the amperage will only be approximately 60% of normal amp draw.
