CAUTION!
Firstly connect the connection pipe to indoor unit, then to outdoor unit; pay attention to the piping
bending, do not damage the connection pipe; the joint nut couldn’t tighten too much, otherwise it
may cause leakage.
4.3.4 Connecting the Pipe at the Outdoor Side Unit
Tighten the flare nut of the connection pipe at
the outdoor unit valve connector. The tightening
method is the same as that as at the indoor side.
