Result: All inert gas escapes from the indoor unit.
Loosen but do not remove completely the flare nuts with plastic caps.
- You should hear gas escaping.
t To prevent dirt or foreign objects from getting into the pipes
during installation, do NOT remove the caps completely until you
are ready to connect the piping.
NOTE
There are two refrigerant pipes of differing diameters:
f
A smaller one for the liquid refrigerant
