5. INSTRUCTION FOR USE

5.1 General instructions

To obtain the best performances in terms of comfort and regulation, the following points should be taken into account:

Orient the air flows correctly so that they do not blow directly onto people. Adjust the set temperature so that it is not too excessive and so that the difference between the inside and the outside temperature is not too large (it is recommenced that this difference does not exceed 8°C). Close all doors and windows in order to maintain energy efficiency and avoid severe condensation (in cooling (COOL) mode or dehumidify (DRY) mode). During the summer months, if possible close shutters on windows to avoid direct sunlight in the room. Do not install objects that may obstruct the air inlet or outlets of the indoor and outdoor units, performance could decrease considerably and the appliance could become a safety hazard. Clean the filters periodically otherwise efficiency may be affected. Before long periods during which the product will not be in use, operate the product in fan only mode for half a day to dry the internal parts then disconnect the power supply and remove the batteries from the remote control. When re-starting the product after a long interval, re-connect the main power supply and wait for half a day before operating the product.

For information :

The compressor will only re-start 3 minutes after a power cut or a regulation stop (antishort protection cycle). Following a power cut, the product will re-start in the operating mode it was set to before the power cut occurred. In heating mode, the indoor unit fan will only begin operating when the temperature of the heat exchanger is high enough to avoid any problems of discomfort.

5.2 Wall-mounted model

The automatic air outlet vents and sweeping vents must be carefully positioned :

A mechanical vent enables the airflow to be directed downwards. This vent is controlled by the remote control (see above).

Note :

Do not attempt to move the indoor unit mechanical vent manually. Do not operate the indoor unit with the mechanical vent in the closed or almost closed position (loss of efficiency or risk of safety hazard). It is not possible to command the mechanical vent when the product is stopped (OFF). Manual deflectors enable the airflow to be directed to the left or the right. Use the lever to position the manual vents, taking care not to touch the fan blades or the horizontal mechanical vent, and also not to damage the manual vents.

5.3 Cassette model

The automatic air outlet vents and sweeping vents must be carefully positioned:

A mechanical vent enables the airflow to be directed downwards. This vent is controlled by the remote control (see above).

Note :

5.4 Duct model

In the event that protective grilles (not provided) are installed over the indoor air outlets, they must be equipped with deflection vents that should ideally be positioned downwards in heating mode and upwards in cooling mode.
