Automatic refrigerant amount detection function (Checking th amount of refrigerant)
This function detects amount of refrigerant in the system through refrigerant amount detection operation
Start
Detect amount of refrigerant
Judge the amount of refrigerant
Satisfy the temperature condition
Press the Tact switch "K2" 4times Input S-NET pro signal
End
(Normal) (Excessive) (Insufficient) (Judgment not
available)
• If the operation cycle is not stable, refrigerant amount detection operation may end.
• Accuracy of the result may decrease if the product was not operated for long period of time before the
refrigerant amount detection operation. Use the refrigerant amount detection operation function after
operating the product in cooling mode for at least 30 minutes.
• Product may trigger protection operation depending on the installation environment. In this case, result of
refrigerant amount detection may not be accurate.
• If escape the warranty temperatures, can not get the accurate results.
- Indoor: 20 ~ 30 °C(68~86°F)
- Outdoor: 5 ~ 43 °C(41~109.4°F)
Actions to take after the detection result
• Exessive amount of refrigerant
- Discharge 5% the detected amount of refrigerant and restart the refrigerant amount detection operation.
• Insufficient amount of refrigerant
- Add 5% of the detected amount of refrigerant and restart the refrigerant amount detection operation.
• Judgment not available
- Check if the refrigerant amount detection operation was executed within guaranteed temperature range.
Execute trial operation to check if there's any other problems on the system.
