10. Installation Instruction 10.1 CU-3E19RBU 10.1.1 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. 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.
