3.9 Gasghtness Test
3.9.1 Purpose
To prevent faults caused by refrigerant leakage, a gasghtness test should be performed before system commissioning.
3.9.2 Procedure
Notes for installers
Warning
Only dry nitrogen should be used for gasghtness tesng. Oxygen, air, ammable gases and toxic gases must not be used for
gasghtness tesng. Use of such gases may result in re or explosion.
Procedure
The gasghtness test procedure is as follows:
Step 1
▪ Once the piping system is complete and the hydronic box and outdoor unit have been connected, vacuum the piping to
-0.1MPa.
Step 2
▪ Charge the piping with nitrogen at 0.3MPa and leave for at least 3 minutes to check large leakage, then 1.5MPa leave for at
least 3 minutes to check small leakage, nally 4.3MPa leave for at least 24 hours to check micro leakage.
▪ Aer the test period of at least 24 hours, observe the pressure in the piping and assess whether or not the observed
pressure indicates the presence of a leak. Allow for any change in ambient temperature over the test period by adjusng the
reference pressure by 0.01MPa per 1°C of temperature dierence. Adjusted reference pressure = Pressure at pressurizaon
+ (temperature at observaon – temperature at pressurizaon) x 0.01MPa. Compare the observed pressure with the
adjusted reference pressure. If they are the same, the piping has passed the gasghtness test.
▪ If the observed pressure is lower than the adjusted reference pressure, the piping has failed the test. Refer to Part 3, 3.9.3
“Leak detecon”. Once the leak has been found and xed, the gasghtness test should be repeated.
Step 3
▪ If not connuing straight to vacuum drying (see Part 3, 3.10 “Vacuum Drying”) once the gasghtness test is complete,
reduce the system pressure to 0.5-0.8MPa and leave the system pressurized unl ready to carry out the vacuum drying
procedure.
