ELECTRICAL CONNECTION

Before plugging into the mains, check the following:

the mains voltage is the same as that indicated on the plate on the back of the appliance;
the socket and electrical line are sized to support the load required;
the socket is the proper type for the plug, otherwise, replace the socket;
the socket is connected to an efficient earthing system. The manufacturer is not responsible in the event of non-compliance with this injuryprevention standards.
The power cable must only be replaced by specialized technicians.

USEThe instructions below will enable you to prepare your air conditioner for operation as efficiently as possible.Before use, make sure the air intake and outlet grilles are unobstructed. |Maintain a minimum distance of 60 cm from walls and obstacles.In conditioning and dehumidification, the air exhaust hose (B1) must be applied (Fig. 1).Please note: This appliance is provided with an auto-evaporation feature for condensate removal during cooling and dehumidifying mode.

AIR CONDITIONING WITHOUT INSTALLATION

CASEMENT WINDOWIf you have a casement window proceed as follows:

Fit the air exhaust hose (B1) in the relevant housing located on the rear side of the appliance (Fig. 1).
Position the air exhaust hose (B1) with the window adapter (B3) outside the window to let the hot air out (Fig. 2).

DOUBLE-HUNG WINDOWDepending on the need, place the self-adhesive strips foam or nonadhesive strip foam on the window as shown in figure 3.

Cut the adhesive strips foam to the desired length and place it on the window.
Position the extendable window bracket on the window sill and fully extend the extendable window bracket inside the window frame (Fig.4)
Adjust the extendable window bracket by fixing the length with two screws (Fig. 5) (If the extendable window bracket is too large, it is possible to cut the plastic using a saw. This operation must be carried out by a qualified professional).
Hook the adapter for the extendable window (B3) to the window bracket as shown in Fig. 6.

MODES SELECTIONTo select the desired operating mode, press repeatedly the MODE key (C2) until the desired function is selected.AIR CONDITIONING MODE

This is ideal for hot and humid weather when the room needs to be both cooled and dehumidified.To correctly set this mode:

Press repeatedly the MODE key (C2) until the air conditioning indicator (C11) appears. The display (C14) will show the desired temperature.
To change the temperature to be reached, press the ν (C3) ^ or (C4) key.
Select the desired fan speed by pressing the (C5) key.

The speeds available are:Minimum airflow: when maximum silent operation is desired.Medium airflow: when the noise level needs to be low but with a good comfort level.Maximum airflow: to reach the desired temperature as soon as possible.AUTO Auto airflow: The appliance automatically chooses the best fan speed based on the temperature selected and the environmental conditions.The most suitable temperatures during the summer range from 24 to 27°C. However, setting a temperature significantly lower than the outdoor temperature is not recommended.

SILENT FUNCTION (available in conditioning mode only and on some models only)

By activating this function in air conditioning mode, the noise of the appliance is further reduced.To activate it, press the button (C6), the indicator (C9) turns on.DEHUMIDIFYING MODE

This is ideal for reducing humidity in the room (spring and autumn, damp rooms, rainy periods, etc).For this type of use, the appliance must be set up for air conditioning mode.That is, the air exhaust hose (B1) must be fitted to the appliance to allow the humidity to be discharged outside.To correctly set this mode:

Press repeatedly the MODE key (C2) until the dehumidifying indicator (C12) appears.
The appliance will automatically choose the best airflow.

Note: in case of high ambient humidity, it is possible to drain the condensate continuously by applying the hose supplied (B5) to the upper drainage hose (A10) and thus allowing the water to flow into a container.Pay attention the water does not overflow onto the floor and the drainage tube is not obstructed (Fig. 9).

FAN MODE

When using this mode, the air exhaust hose (B1) does not need to be attached to the appliance.To correctly set this mode:

Press repeatedly the MODE (C2) key until the fan indicator lights on.
Pressing repeatedly the (C5) key till the desired airflow is selected.

The available air flows are:Minimum airflow: when most silent operation is desired.Medium airflow: when the noise level needs to be low but with a good comfort level.Maximum airflow: for maximum performance.
