A flashing H means the chiller is not cooling. The oil temperature is above the upper limit.

What to check

  • Warm air from the top of the chiller. If the air coming out is warm but the oil is not being cooled, the refrigerant has most likely leaked out.
  • Airflow first. Rule out a clogged air filter or condenser and a stopped fan. See Alarm 02.

Refrigerant leaks need a technician

Finding and repairing a leak, and recharging refrigerant (R407C or R410A depending on model), must be done by an EPA 608 certified refrigeration technician. Call us. We can quote the repair parts or a replacement chiller.

Repair parts

Kwangrim recommends replacing the dryer whenever the compressor is replaced.

These steps come from Kwangrim service documentation and apply to Kwangrim NANOCON CIL, CIC and CIW chillers. Turn off and lock out power before opening the chiller. Electrical and refrigeration work should be done by qualified technicians.
