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.
Step 1: Select installation location
Before installing the indoor unit, you must
choose an appropriate location. The following
are standards that will help you choose an
appropriate location for the unit.
Proper installation locations meet the
following standards:
Good air circulation
Convenient drainage
Noise from the unit will not disturb other
people
Firm and solid—the location will not vibrate
Strong enough to support the weight of the
unit
DO NOT install unit in the following
locations:
Near any source of heat, steam, or
combustible gas
Near flammable items such as curtains or
clothing
Near any obstacle that might block air
circulation
Near the doorway
In a location subject to direct sunlight
NOTE ABOUT WALL HOLE:
If there is no fixed 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.
A location at least one meter from all other
electrical devices (e.g., TV, radio, computer)
