Additional notes on connecting
the refrigerant piping
n
When combining the outdoor unit with some
indoor units, the procedure for connecting the
refrigerant piping may differ. Install the pro-
vided reducer or expansion fittings to the
indoor unit.
n
If the basic length of the connecting line
exceeds 5m, add refrigerant when commis-
sioning the system for the first time (see
chapter "Adding refrigerant").
