If an awning is built over the unit to prevent direct sunlight or rain, be careful that heat radiation from the

There should not be any animal or plant which could be affected by hot air discharged.
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.
