11.4.1 Select the Best Location
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.
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. machinery oil, etc), it
lifespan maybe shorten.
When installing the product in a place where it will be affected by typhoon or strong wind such as wind blowing
between buildings, including the rooftop of a building and a place where there is no building in surroundings, fix
the product with an overturn prevention wire, etc. (Overturn prevention fitting model number: K-KYZP15C) (For
