NOTICE
▪ Do NOT stack the units on each other.
▪ Do NOT hang the unit on a ceiling.
When the outdoor unit is subject to windy and/or low ambient
temperatures, mind the following guidelines:
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;
▪ 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.

▪ Choose a location where the hot/cold air discharged from the unit
or the operation noise, will NOT disturb anyone.
▪ Heat exchanger fins are sharp and injury is possible. Choose an
installation location where there is no risk for injury (especially in
areas where children playing).
▪ Do NOT install the unit in sound sensitive areas (e.g. near a
bedroom and the like), so that the operation noise will cause no
trouble.
Note: If the sound is measured under actual installation
conditions, the measured value will be higher than the sound
pressure level mentioned in "15.10 Sound spectrum" on page 103
due to environmental noise and sound reflections.
It is NOT recommended to install the unit in the following places
because it may shorten the life of the unit:
▪ in coastal areas or other places where the air contains high levels
of salt. Corrosion may occur,
▪ where the voltage fluctuates a lot,
▪ in vehicles or vessels,
▪ where acidic or alkaline vapour is present.

Additional installation site requirements
of the outdoor unit in cold climates
Protect the outdoor unit against direct snowfall and take care that the
outdoor unit is NEVER snowed up.

▪ The unit should be installed in a way that a minimum of 15 cm free
space is assured below the bottom plate of the unit at all weather
conditions (e.g., heavy snowfall). It is recommended to install the
unit at a minimum height of 30 cm. See "7.2 Mounting the outdoor
unit" on page 27 for more details.
▪ In heavy snowfall areas it is very important to select an installation
site where the snow will NOT affect the unit. If lateral snowfall is
possible, make sure that the heat exchanger coil is NOT affected
by the snow. If necessary, install a snow cover or shed and a
pedestal.
