PRIOR TO INSTALLATION
NOTE ABOUT WALL HOLE:
Before installing the indoor unit, refer to the
label on the product box to make sure that
the model number of the indoor unit matches
the model number of the outdoor unit.
If there is no xed refrigerant piping:
While choosing a location, be aware that you
should leave ample room for a wall hole (see
Drill wall hole for connective piping step)
for the signal cable and refrigerant piping
that connect the indoor and outdoor units.
The default position for all piping is the right
side of the indoor unit (while facing the unit).
However, the unit can accommodate piping to
both the left and right.
