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 and resin parts).

• 

Make sure to check in advance that the refrigerant to be 
used for installation work is R410A. 
The air conditioner will not operate properly without the 
correct refrigerant.

• 

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 until the installation 
begins.
(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).

• 

For selection of installation location, use the installation 
pattern paper as reference.

• 

Do not use the air conditioner where in the salty atmo-
sphere such as coastal areas, vehicles, vessels or the 

voltage fluctuation 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.
