If an awning is built over the unit to prevent direct sunlight or rain, be careful that heat radiation from the
condenser is not obstructed.
Avoid installations in areas where the ambient temperature may drop below -20°C.
Keep the spaces indicated by arrows from wall, ceiling, fence or other obstacles.
Do not place any obstacles which may cause a short circuit of the discharged air.
If outdoor unit installed near sea, region with high content of sulphur or oily location (e.g. machinary oil, etc), it
