After completing all the operations, the system is ready for submission to the leak test and the whole refrigerant
fluid loading process.
5.3.6. Leak test
A nitrogen load at a pressure of 10 bar (Max) would be ideal to ensure that there are no leaks on the welds carried
out. Once the installation is loaded, cover all the welds in soapy water and check that there are no nitrogen leaks.
The panels must remain 2 to 3 days with the nitrogen load so as to ensure that there is no leak. Once this operation
has been completed, remove all the nitrogen from the installation.
5.3.7. Vacuum
This operation is carried out using one load pipe, that is located inside of the unit, at the aspiration pipe. During this
operation, the two hermetic valves should be closed as factory instalation.
Before loading the refrigerant fluid, it is vital to carry out a vacuum at the installation. The purpose of the vacuum is
to remove all the air and humidity to be found on the circuit. The vacuum time depends on the following factors:
✓ Volume in m
3
/h of the vacuum pump.
✓
Volume of the system piping.
On average, the minimum vacuum time to be carried out at an installation, depending on the system installed, is
shown in the table below.
