unit as shown in the left diagram.
• A place which can bear the weight of the outdoor unit and
does not allow an increase in noise level and vibration.
• A place where the operation noise and discharged air
do not disturb users neighbors.
• A place which is not exposed to a strong wind.
• A place free of a leakage of combustible gases.
• A place which does not block a passage.
• When the outdoor unit is to be installed in an elevated
position,be sure to secure its feet.
• This air cinditioner accepts a connection piping length
of up to 25 m.
• There is no need to add refrigerant as long as the
length of the connection piping is 15 m or less.
• You will need to add 20g of refrigerant per meter of
added connnection piping for installations requiring
connection piping to be between 16 m to 25 m.
• An allowable height level is up to 10 m.

problem.
Precautions for adding refrigerant
• Use a scale having a precision with at least 10 g per
index line when adding the refrigerant. Do not use a
bathroom scale or similar instrument.
• Use liquid refrigerant when refilling the refrigerant.
Since the refrigerant is in liquid form, it can fill quickly.
Therefore, perform the filling operation carefully and
insert the refrigerant gradually.
CAUTION

the air discharging.
2. When the outdoor unit is installed in a place
exposed always to a strong wind like a coast or on
