1. Important notes
If the unit or its refrigerant circuit components experience malfunctions, take the following steps to prevent recurrence.
(1) Diagnose the problem and find the cause.
(2) Before repairing leaks on the brazed sections on the pipes, recover the refrigerant. Braze under nitrogen purge to prevent
oxidation.
(3) If any component (including the compressor) malfunctions, only replace the affected parts; it is not necessary to replace
the entire unit.
(4) Be sure to recover the refrigerant from the unit before disposing of the unit.
(5) If the cause of the problem cannot be identified, contact the service desk with the following information: unit model, serial
number, and the nature of the problem.
