NOTICE
▪
Do NOT stack the units on each other.
▪
Do NOT hang the unit on a ceiling.
Strong winds (≥18 km/h) blowing against the outdoor unit’s air outlet causes short
circuit (suction of discharge air). This may result in:
▪
deterioration of the operational capacity;
▪
frequent frost acceleration in heating operation;
▪
disruption of operation due to decrease of low pressure or increase of high
pressure;
▪
a broken fan (if a strong wind blows continuously on the fan, it may start rotating
very fast, until it breaks).
It is recommended to install a baffle plate when the air outlet is exposed to wind.
It is recommended to install the outdoor unit with the air inlet facing the wall and
NOT directly exposed to the wind.

Do NOT install the unit in the following places:
▪
Sound sensitive areas (e.g. near a bedroom), so that the operation noise will
cause no trouble.
Note:
If the sound is measured under actual installation conditions, the
measured value might be higher than the sound pressure level mentioned in
Sound spectrum in the data book due to environmental noise and sound
reflections.
▪
In places where a mineral oil mist, spray or vapour may be present in the
atmosphere. Plastic parts may deteriorate and fall off or cause water leakage.
It is NOT recommended to install the unit in the following places because it may
shorten the life of the unit:
▪
Where the voltage fluctuates a lot
