2. BEFORE INSTALLATION
When unpacking the indoor unit or moving the unit after
unpacked, hold the hangers (4 places) and do not apply
force to other parts (particularly refrigerant piping, drain
piping).
• For installation of the outdoor unit, refer to the installation
manual attached to the outdoor unit.
• Do not throw away the accessories until the installation work
is completed.
• After the indoor unit is carried into the room, to avoid the
indoor unit from getting damaged, take measures to protect
the indoor unit with packing materials.
(1) Determine the route to carry the unit into the room.
(2) Do not unpack the unit until it is carried to the
installation location.
Where unpacking is unavoidable, use a sling of soft
material or protective plates together with a rope when
lifting, to avoid damage or scratches to the indoor unit.
• Have the user actually operate the air conditioner while
looking at the operation manual.
Instruct the user how to operate the air conditioner
(particularly operation pro cedures, and temperature
adjustment).
• Do not use the air conditioner in a salty atmosphere such as
coastalareas,vehicles,vesselsorwherevoltageuctuation
is frequent such as factories.
• Take off static electricity from the body when carrying out
wiring and the electrical wiring box cover is removed.
The electric parts may be damaged.
