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).
•
Make sure to check in advance that the refrigerant to be
used for installation work is R410A.
(The air conditioner will not properly operate if a wrong
refrigerant is used.)
•
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 installa-
tion 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 customer actually operate the air conditioner
while looking at the operation manual.
Instruct the customer how to operate the air conditioner
(particularly cleaning of the air filters, operation pro cedures,
and temperature adjustment).
•
Do not use the air conditioner in a salty atmosphere such
as coastal areas, vehicles, vessels or where voltage fluc
-
tuation is frequent such as factories.
•
Take off static electricity from the body when carrying out
wiring and the control box lid is removed.
The electric parts may be damaged.
