Test the leak-tightness
1. Open the plugs in the A and B / C stop valves.
2. Check that A and B / C stop valves are closed.
3. Remove the plug from the service connection on A stop valve.
4. Connect the pressure gauge and the nitrogen bottle to the stop valve
A then progressively build up the pressure in the refrigerant
connection pipes and the indoor module to 35 bar, in 5 bar
increments.
5. Check the leak-tightness of the fittings using a leak detector spray. If
leaks appear, repeat the steps in order and check the leak-tightness
once again.
6. Release the pressure and release the nitrogen.
