power switch is shut off, it must interrupt all phases )
*2 Use wires in conformity with design 60245 IEC 57
*3 Never use pipes with thickness less than speci ed The pressure resistance will e insuf cient
*4 Use a copper pipe or a copper alloy seamless pipe
*5 e careful not to crush or end the pipe during pipe ending
*6 Refrigerant pipe ending radius must e 100 mm or more
*7 If pipe length exceeds 7 m, additional refrigerant (R32) charge is required (No additional charge is required for pipe length less
than 7 m )
Additional refrigerant = A × (pipe length (m) – 7)
*8 Insulation material eat resisting foam plastic 0 045 speci c gravity
*9 e sure to use the insulation of speci ed thickness Excessive thickness may cause incorrect installation of the indoor unit and
insuf cient thickness may cause dew drippage
■ Do not install the outdoor unit where small animals
may live.
If small animals enter and touch the electric parts inside
the unit, it could cause a malfunction, smoke emission,
or re Also, advise user to keep the area around the unit
clean
■ Do not operate the air conditioner during interior
construction and nishing work, or while waxing the
oor.
efore operating the air conditioner, ventilate the room
well after such work is performed Otherwise, it may cause
volatile elements to adhere inside the air conditioner,
resulting in water leakage or scattering of dew

OUTDOOR UNIT
Where it is not exposed to strong wind If the outdoor unit is exposed to a wind during
defrosting, the defrosting time will e longer
Where air ow is good and dustless
Where rain or direct sunlight can e avoided as much as possi le
Where neigh ours are not annoyed y operation sound or hot (or cool) air
Where rigid wall or support is availa le to prevent the increase of operation sound or
vi ration
Where there is no risk of com usti le gas leakage
When installing the unit at a high level, e sure to secure the unit legs
Where it is at least 3 m away from the antenna of TV set or radio Operation of the air
conditioner may interfere with radio or TV reception in areas where reception is weak
An ampli er may e required for the affected device
Install the unit horizontally
Please install it in an area not affected y snowfall or lowing snow In areas with heavy
snow, please install a canopy, a pedestal and/or some af e oards
Note:
It is advisa le to make a piping loop near outdoor unit so as to reduce vi ration transmit
ted from there
Note:
When operating the air conditioner in low outside temperature, e sure to follow the
instructions descri ed elow
Never install the outdoor unit in a place where its air inlet/outlet side may e exposed
directly to wind
To prevent exposure to wind, install the outdoor unit with its air inlet side facing the
wall
To prevent exposure to wind, it is recommended to install a af e oard on the air outlet
side of the outdoor unit
Avoid the following places for installation where air conditioner trou le is lia le to occur
Where amma le gas could leak
Where there is much machine oil
Where oil is splashed or where the area is lled with oily smoke (such as cooking areas
and factories, in which the properties of plastic could e changed and damaged)
Salty places such as the seaside
Where sul de gas is generated such as hot spring, sewage, waste water
Where there is high frequency or wireless equipment
Where there is emission of high levels of VOCs, including phthalate compounds,
formaldehyde, etc , which may cause chemical cracking
