    OPERATION Unit Heat Control Operation - Heat Pump With Electric Heat Automatic Emergency Heat If the sealed system fails with a bad reversing valve or anything that causes the indoor coil to get colder than the indoor ambient temperature: 1) If the indoor coil thermistor senses a 5 degree temperature drop as compared to the ambient temperature thermistor and this lasts up to 5 minutes, the control board will switch the unit to electric heat and continue heating with it.

  • Page 27: Refrigeration Sequence Of Operation

    OPERATION Refrigeration Sequence Of Operation A good understanding of the basic operation of the refrigeration system is essential for the service technician. Without this understanding, accurate troubleshooting of refrigeration system problems will be more difficult and time consuming, if not (in some cases) entirely impossible.
  • Page 28 Routine Maintenance Coils & Chassis NOTE: Do not use a caustic cleaning agent on coils or base pan. Use a biodegradable cleaning agent and degreaser. The use of harsh cleaning materials may lead to deterioration of the aluminum fins or the coil end plates. The indoor coil and outdoor coils and base pan should be inspected periodically (annually or semi-annually) and cleaned of all debris (lint, dirt, leaves, paper, etc.) as necessary.
