▪ 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.
INFORMATION
The sound pressure level is less than 70dBA.
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
▪ In vehicles or vessels
▪ Where acidic or alkaline vapour is present
Seaside installation. Make sure the outdoor unit is NOT directly exposed to sea
winds. This is to prevent corrosion caused by high levels of salt in the air, which
might shorten the life of the unit.
Install the outdoor unit away from direct sea winds.

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;
