Context
● The leakage test with nitrogen described in this section is dedicated for testing
the leaks of the indoor unit and the pipes connected to it.
● The measuring range of the pressure gauge must be greater than or equal to
4.0 MPa, and the tolerance range of the leather hose must be greater than or
equal to 4.5 MPa.
● During the pressure preservation process, do not remove the leather hose and
pressure gauge; otherwise, nitrogen may leak.
