  • Page 11: Refrigerant Overcharge Symptoms

    Refrigerant Overcharge Symptoms • Above normal freezer temperature. • Compressor running continuously. • Freezing in refrigerator due to Chef’ s Pantry .•High suction and head pressure. • High wattage. • Warm evaporator inlet and outlet temperature. • Below ambient suction tube temperature. Check for separated heat exchanger when suction temperature is colder than ambient.

  • Page 12: Air In System Symptoms

    Air in System Symptoms Air in system can be caused by low side leak or improper servicing. If low side leak occurs, temperature control will not achieve temperatures and compressor will run continuously. Compressor will eventually pump low side into a vacuum, drawing air and moisture into system.

  • Page 13: Hfc134A Service Information

    HFC134a Service Information HFC134a is alternative refrigerant for CFC12. HFC134a has an ozone depletion potential (ODP) factor of 0.0 and a global warming potential (GWP) factor of 0.27. HFC134a is not flammable and has acceptable toxicity levels. HFC134a is not interchangeable with CFC12.

  • Page 14: Service Equipment

    HFC134a Service Information Service Equipment Listed below is equipment needed for proper servicing of HFC134a systems. Verify equipment is confirmed by manufacturer as being compatible with HFC134a and ester oil system. Equipment must be exclusively used for HFC134a. Exclusive use of equipment only applies to italic items.

  • Page 15: Replacement Service Compressor

    Replacement Service Compressor HFC134a service compressors will be charged with ester oil and pressurized with dry nitrogen. Before replacement compressor is installed, pull out 1 rubber plug. A pop from pressure release should be heard. If a pop sound is not heard, do not use compressor. Positive pressure in compressor is vital to keep moisture out of ester oil.
  • Page 16 7. Check serial plate for correct charge and set scale on dial-a-charge cylinder for corresponding HFC134a pressure reading. Do not use captured or recycled refrigerant in Amana of captured or recycled refrigerant voids any warranty. 8. Open valve “ F” to charging cylinder and let exact amount of refrigerant out of cylinder.
