per part of the unit. The unit should be kept horizontal throughout
the lifting operation. If necessary, tie guide ropes on to prevent the
unit from swinging freely during the lifting process.

7 UNIT INSTALLATION
7.1 PRELIMINARY CONDITIONS FOR POSITIONING OF OUTDOOR UNIT
Mount the outdoor unit in a shady location or where it will not be
exposed to direct sunlight, or to high temperatures. It should also
be a well-ventilated spot.
Mount the outdoor unit so that noises and the discharge of air
from the unit will not bother neighbours or the surrounding envi-
ronment.
Install the outdoor unit in an area of limited access to the general
public.
In cold climates, ice may form on the unit. When installing the
unit, make sure that ice falling off the unit could not pose a risk to
passers-by.
When installing the outdoor unit in areas covered by snow, mount
the covers supplied by the tter on the top of the unit and on the
heat exchanger inlet side.
Do not install the outdoor unit in zones where dust or contamina-
tion could block the outside heat exchanger.
Do not install the outdoor unit in areas with a high air content of
oil, saline atmospheres or aggressive gases such as sulphur.
Do not install the outdoor unit close to sources of strong elec-
tromagnetic radiation or in areas where electromagnetic waves
radiate directly towards the electrical box and the components
of the unit. Install the unit as far as possible from these sources
(minimum 3 metres); electronic noise may result in the incorrect
operation of the unit.
CAUTION
In areas with high electromagnetic turbulence, a fuse may blow or
the unit stop or an alarm may be triggered. In this case, stop the
system and restart it to remove the alarm.
Make sure that the base of the foundations is at and strong
enough to bear the weight of the unit.
Install the outdoor unit in an area with enough space around the
unit to permit service and maintenance tasks.
CAUTION
• The aluminium ns have sharp edges. Take special care to
avoid injury.
• The outdoor unit must be installed on rooftops or in areas not
accessible by the user. Only service technicians and mainte-
nance personnel are permitted access to the unit.
