7.1 Preparing the installation site
Do NOT install the unit in places often used as work place. In case of construction
works (e.g. grinding works) where a lot of dust is created, the unit MUST be
covered.
Choose an installation location with sufficient space for carrying the unit in and out
of the site.
WARNING
The appliance shall be stored so as to prevent mechanical damage and in a well-
ventilated room without continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric heater).

INFORMATION
Also read the precautions and requirements in the "2 General safety
precautions"[49].
Mind the spacing guidelines. See "17.1Service space: Outdoor unit"[4254].
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).
