This function determines the refrigerant level of system through the refrigerant level checking operation.
■
Beyond the temperature range of warranty, it is not possible to obtain an accurate result.
- Indoor: 20 ~ 32°C
- Outdoor: 5 ~ 43°C
■
When the operational cycle is not stable, the refrigerant level detection operation may be forcefully terminated.
■
When the system has not been used for a long time prior to the refrigerant level detection operation, the accuracy may be dropped.
Hence, please try to run the system in cooling mode for 30 or minutes in advance.
■
According to the installation environment, the refrigerant level checking result may not be accurate when running the system in
protection mode.
Action to Judgment Result
■
Excessive Refrigerant Level: After removing 5% of refrigerant from the calculated refrigerant level, please try to run the refrigerant level
detection function again.
■
Insufficient Refrigerant Level: After adding 5% of refrigerant to the calculated refrigerant level, please try to run the refrigerant level
detection function again.
■
Excessive Lack of Refrigerant: After adding 10% of refrigerant to the calculated refrigerant level, please try to run the refrigerant level
detection function again.
■
Unable to Judge: Please check whether the system operates within the temperature range of warranty for the refrigerant level detection
