2.1 Outdoor unit
2.1.1 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
environment.
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 fitter on the top of the unit and
on the heat exchanger inlet side.
Do not install the outdoor unit in zones where dust or contamination 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 electromagnetic 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.
C A U T I O N
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 flat 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.
C A U T I O N
•
The aluminium fins 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 maintenance personnel are permitted access to the unit.
2.1.2 Transport, lifting and handling of the units
¿
Transport of outdoor unit
When transporting the unit, make sure that it is securely and
correctly fastened to the vehicle to avoid damage. To avoid
damage, use appropriate textile slings -A- and cardboard
protection -B- to ensure that the unit is immobilised without
damaging it.
Use a suitable crane with the required loading capacity on flat
ground when loading and unloading the unit.
C A U T I O N
Do not place other material on top of the outdoor units during
transport and storage.
If the unit is not installed immediately, it should be stored in a suitable location, protected from the elements, especially in
saline atmospheres and from rodents. The unit must be stored with all the transport protection with which it was supplied
and with the wooden base -C- fitted.
