( Table 3 : Compressor frequency range )
01-02
3. DRY OPERATION
The compressor frequency shall change according to the temperature, set temperature,
and room temperature variation which the room temperature sensor of the indoor unit body has
detected as shown in the Table 4.
However, after the compressor is driven, the outdoor unit shall run at operation frequency of
51rps (9RLFF), 51rps (12RLFF), 52rps (15RLFF) for a minute.

A sensor (room temperature thermistor) built in the indoor unit body will usually perceive
difference or variation between a set temperature and present room temperature, and
controls the operation frequency of the compressor.
* If the room temperature is lower by 6°F(3°C) than a set temperature, the compressor operation
frequency will attain to maximum performance.
* If the room temperature is higher 5°F(2.5°C) than a set temperatire, the compressor will be
stopped.
* When the room temperature is between +5°F(+2.5°C) to -6°F(-3°C) of the setting temperature,
the compressor frequency is controlled within the range shown in Table 3.
