Ɣ If escape the warranty temperatures, can not get the accurate results.
- Indoor : 20~30°C
- Outdoor : 5~43°C
Ɣ If operation cycle is not stabl
e, Checking the amount of refrigerant can be forced to shut down.
Ɣ If did not operation for a long time, or when running the heating operation,
the accuracy may be lower.
Therefore carried out for more than 30 minutes cooling operation.
Ɣ Depending on the installation environment, system protection
operation is performed, in this case, the check result may be inaccurate.
[How to troubleshoot the judged results]
Ɣ Excessive of refrigerant amount : After the 5% emissions of calculated tot
al refrigerant amount, retry Checking the amount of refrigerant.
Ɣ Deficiency of refrigerant amount : After the 5% addition of calculated tota
l refrigerant amount, retry Checking the amount of refrigerant.
Ɣ Deficiency of Over-cooling : After the 10% addition of calculated total refri
gerant amount, retry Checking the amount of refrigerant.
Ɣ Undetermined : Checking the amount of refrigerant confirms that is performed in
warranty temperatures area.
