Checking before useOperation rangesThe table below indicates the temperature and humidity ranges the airconditioner can be operated within. Refer to the table for efficient use.Maintaining your air conditioner The standardized temperature for heating is 7˚C. If the outdoor temperature drops to 0˚C or below, the heating capacity canbe reduced depending on the temperature condition. If the cooling operation is used at over 32˚C(indoor temperature), it does not cool at its full capacity.Internal protections via the unit control system This internal protection operates if an internal fault occurs in the air conditioner.• If the heat pump is operating in Heat mode, defrost cycle is actuated to help remove frost from an outdoor unit thatmay have deposited at low temperatures.The internal fan is switched off automatically and restarted only after the defrost cycle is completed.Type DescriptionAgainst cold air The internal fan will be off to prevent cold air when the heat pump is heating.Defrost cycleThe internal fan will be off to defrost ice when the heat pump is heating.Vertical air flow blade will be closed during defrost cycle and it will open again duringheating operation after defrost cycle.Protect compressor The air conditioner does not start operating immediately to help protect the compressorof the outdoor unit after it has been started.MODE OPERATIONAL TEMPERATURE INDOOR HUMIDITY IF OUT OF CONDITIONSINDOOR OUTDOORCOOLING 16˚C to 32˚C -5˚C to 48˚ 80% or lessCondensation may occur on the indoor unitwith risk to have either water blow off or dropson the floor.HEATING 27˚C or less -20˚C to 24˚C - Internal protection triggers and the airconditioner will stop.DRYING 16˚C to 32˚C -5˚C to 48˚C -Condensation may occur on the indoor unitwith risk to have either water blow off or dropson the floor.English-10
