72GB-52. OPEATION2.2 HOW IT WORKSIn this setting the system will automatically change modes and fan speed to the set temperature.[In spring and autumn, closer temperature control may require COOL/HEAT mode changes.]In this mode, priority is given to dehumidifying the air. Low fan speed and compressor cycling is used to achievethis and regulate room temperature.AUTO ModeDRY ModeBasic Operation Modes AUTO / COOL / DRY / HEAT / FANAt start-up, a time delay of 3 to 4 minutes protects the compressor.Compressor DelayTo avoid uncomfortable drafts in heating mode, the indoor unit is preheated before the fan starts. This delayshould only last a few minutes.Cold Draft PreventionIce develops on the outdoor unit in heating mode. To defrost this ice, the indoor fan stops for a few minutesbefore heating continues.Auto DefrostThe unit will automatically restart after a power interruption. Previous user settings are all recovered.Auto Restart*When refrigerant leakage is detected, the unit will display “EC” code or flash LEDs.Auto Leak Detection*2.3 HINTS FOR ECONOMICAL OPERATION[*] Model dependentLouver angle is memorised and will return to the position last selected by the user.Louver Memory*Press “AIR DIRECTION” on remote controller to adjust air flow direction. The louver position movesslightly each time the button is pressed.Press “SWING” to engage continous louver motion.Adjusting Air Flow DirectionAdjust the temperature to achieve moderate comfort levels. Excessively low or high temperatureswaste energy.Improve performance by keeping windows and doors closed.Limit energy usage [run time] by using the TIMER function.Do not block air inlets or outlets. Poor performance, increased running costs and reduced product lifewill result.Inspect the air filters periodically, and clean them when needed.Disconnect the power source if unit will not be used for a long period.Please refer to the REMOTECONTROLLER MANUAL for details.In cooling or dry mode, condensate mayform and drip from unit in high humiditycondition if louver position is in Maximumdown.Do not operater the unit with louverclosed or narrow opening. Restricted airflow reduced performance and maycause condensate.NOTECAUTIONDo not attempt to adjust the louver by hand.
