2. TROUBLESHOOTING AIR CONDITIONER
Refrigeration cycle system
In order to diagnose malfunctions, make sure that
there are no electrical problems before inspect-
ing the refrigeration cycle. Such problems include
insufficient insulation, problem with the power source,
malfunction of a compressor or a fan.
The normal outlet air temperature and pressure
of the refrigeration cycle depends on various condi-
tions; the standard values for them are shown in the
table on the right.
Normal Pressure and Outlet Air Temperature (Standard)

★ Condition: • Indoor fan speed; High.
• Outdoor temperature is 35°C at cooling
mode and 7°C at heating mode.
• Compressor operates at rated frequency.
