R410A Pressure Temperature Chart - Zanussi ZS12V70CCHI Service Manual

The charging process should be finished after the required amount is charged in to the system and remove the manifold and
refrigerant hose.
2. Refrigerant Leakage on the System
First of all the leakage point should be repaired on the system.
For example that there is a leakage on the service valve at piping connection.
The piping connection point should be repaired and all the process above should be repeated for charging the refrigerant.
– Vacuum first.
– Vacuum quality and reliability check.
– Refrigerant charge.
The photos above left to right;
The refrigerant tank should be placed upside down on the electronic scale.
The quality manifold and hoses should be used.
The vacuum process always should be applied.
The R410a compressors uses POE oil inside and POE oil is high sensitive about humidity.
Vacuum process is most important stage before the charging process.
