If this happens, use another heatingdevice together with the unit. (When using together withappliances that produce open fire, ventilate the roomconstantly). Do not place appliances that produce openfire in places exposed to the air flow from the unit orunder the unit.▪ It takes some time to heat up the room from the timethe unit is started since the unit uses a hot-aircirculating system to heat the entire room.▪ If the hot air rises to the ceiling, leaving the area abovethe floor cold, we recommend that you use thecirculator (the indoor fan for circulating air). Contactyour dealer for details.15.2.4 To operate the system1 Press the operation mode selector button on the user interfaceseveral times and select the operation mode of your choice.Cooling operationHeating operationFan only operation2 Press the ON/OFF button on the user interface.Result: The operation lamp lights up and the system startsoperating.15.3 Using the dry program15.3.1 About the dry program▪ The function of this program is to decrease the humidity in yourroom with minimal temperature decrease (minimal room cooling).▪ The micro computer automatically determines temperature andfan speed (cannot be set by the user interface).▪ The system does not go into operation if the room temperature islow (<20°C).15.3.2 To use the dry programTo start1 Press the operation mode selector button on the user interfaceseveral times and select (program dry operation).2 Press the ON/OFF button of the user interface.Result: The operation lamp lights up and the system startsoperating.To stop3 Press the ON/OFF button on the user interface once again.Result: The operation lamp goes out and the system stopsoperating.NOTICEDo not turn off power immediately after the unit stops, butwait for at least 5 minutes.15.4 Adjusting the air flow directionRefer to the operation manual of the user interface.15.4.1 About the air flow flapDouble flow+multi-flow unitsFor the following conditions, a micro computer controls the air flowdirection which may be different from the display.Cooling Heating▪ When the room temperature islower than the settemperature.▪ When starting operation.▪ When the room temperature ishigher than the settemperature.▪ At defrost operation.▪ When operating continuously at horizontal air flow direction.▪ When continuous operation with downward air flow is performedat the time of cooling with a ceiling-suspended or a wall-mountedunit, the micro computer may control the flow direction, and thenthe user interface indication will also change.The air flow direction can be adjusted in one of the following ways:▪ The air flow flap itself adjusts its position.▪ The air flow direction can be fixed by the user.▪ Automatic and desired position .WARNINGNever touch the air outlet or the horizontal blades while theswing flap is in operation. Fingers may become caught orthe unit may break down.NOTICE▪ The movable limit of the flap is changeable. Contactyour dealer for details. (only for double-flow, multi-flow,corner, ceiling-suspended and wall-mounted).▪ Avoid operating in the horizontal direction . It maycause dew or dust to settle on the ceiling or flap.16 Energy saving and optimumoperationObserve the following precautions to ensure the system operatesproperly.▪ Adjust the air outlet properly and avoid direct air flow to roominhabitants.▪ Adjust the room temperature properly for a comfortableenvironment. Avoid excessive heating or cooling.▪ Prevent direct sunlight from entering a room during coolingoperation by using curtains or blinds.▪ Ventilate often. Extended use requires special attention toventilation.▪ Keep doors and windows closed. If the doors and windows remainopen, air will flow out of your room causing a decrease in thecooling or heating effect.▪ Be careful not to cool or heat too much. To save energy, keep thetemperature setting at a moderate level.▪ Never place objects near the air inlet or the air outlet of the unit. Itmay cause deterioration in the effect or stop the operation.▪ Turn off the main power supply switch to the unit when the unit isnot used for longer periods of time. If the switch is on, it consumeselectricity. Before restarting the unit, turn on the main powersupply switch 6 hours before operation to ensure smooth running.▪ When the display shows (time to clean the air filter), clean thefilters (see "17.1.1 To clean the air filter" on page 27).▪ Keep the indoor unit and user interface at least 1 m away fromtelevisions, radios, stereos, and other similar equipment. Failing todo so may cause static or distorted pictures.
