In order to diagnose malfunctions, make sure that there are no
electrical problems before inspecting the refrigeration cycle.
Such problems include insufficient insulation, problem with the
power source, malfunction of a compressor and a fan.
The normal outlet air temperature and pressure of the refrigeration
cycle depends on various conditions, the standard values for them
are shown in the table on the right.

*Condition: • Indoor fan speed = High
• Outdoor temperature 35°C at the cooling
mode and 7°C at the heating mode
• Compressor operates at rated frequency
