If pump down is needed in case of dismantling or relocating the system, see
"15.2To pump down"[460] for more details.
8.7 To check refrigerant piping joints for leaks after charging refrigerant
1 Perform the leak tests see "7.3Checking the refrigerant piping"[438].
2 Charge refrigerant.
3 Check for refrigerant leaks after charging (see below)
Tightness test of field-made refrigerant joints indoors
1 Use a leakage test method with a minimum sensitivity of 5 g of refrigerant/
year. Test leaks using a pressure of at least 0.25 times the maximum working
pressure (see "PS High" on the unit nameplate).
If a leak is detected
1 Recover the refrigerant, repair the joint, and repeat the test.

NOTICE
Applicable legislation on fluorinated greenhouse gases requires that the refrigerant
charge of the unit is indicated both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO

equivalent tonnes: GWP value of the
refrigerant × total refrigerant charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge label.
2 Fix the label on the inside of the outdoor unit near the gas and liquid stop
valves.
