TIPS FOR CORRECT USE

To ensure optimal results from your air conditioner, follow these recommendations:

Close the windows and doors in the room to be air conditioned. When installing the air conditioner semi-permanently, you should leave a door slightly open (as little as 1 cm) to guarantee proper ventilation.
Never use the appliance in very damp rooms (laundries for example).
Protect the room from direct exposure to the sun by partially closing curtains and/or blinds to make the appliance much more economical to run.
Never use the appliance outdoors.
Make sure there are no heat sources in the room.
make sure the air conditioner is standing on a level surface.
Never rest objects of any kind on the air conditioner.
Never obstruct the air intake or outlet grilles.

CLEANING

Before cleaning or maintenance, turn the appliance off by touching the button, then unplug from the outlet.

CLEANING THE CABINET
You should clean the appliance with a slightly damp cloth then dry with a dry cloth. For safety reasons, never wash the air conditioner with water.
Attention! Never use petrol, alcohol or solvents to clean the appliance. Never spray insecticide liquids or similar.

CLEANING THE BIO SILVER AIR FILTER
The BioSilver filter helps capture dust and pollen and helps reduce the growth of bacteria and mold on the filter.
If the filter is dirty, air circulation is compromised and the efficiency of the appliance decreases. It is therefore good practice to clean the filter at regular intervals. The frequency depends on the duration and conditions of operation. If the unit is used constantly or systematically, you are recommended to clean the filter once a week.
The filter is housed in the intake grille. To clean the filter, extract as shown in fig. 11.
Use a vacuum cleaner to remove the dust collected on the filter.
If it is very dirty, immerse in warm water and rinse a number of times. The water should never be hotter than 40°C.
After washing the filter, allow it to dry completely before repositioning it.

START OF SEASON CHECKS
Make sure the power cable and plug are undamaged and the earth system is efficient.
Follow the installation instructions precisely.

END OF SEASON OPERATIONS
To drain all water from the circuit, remove the external cap by unscrewing it in the anticlockwise direction (fig. 12) and allow the water to drain out into a basin.
When the appliance is empty, replace the caps.
Clean the filter and dry thoroughly before putting back.

Attention! TO AVOID DAMAGE TO THE UNIT:

NEVER TRANSPORT OR TURN THE APPLIANCE UPSIDE DOWN OR ON ITS SIDE. IF THIS OCCURS, WAIT 6 HOURS BEFORE TURNING
THE APPLIANCE ON, 24 HOURS IS RECOMMENDED. After the unit has been on its side, oil needs to return to the compressor to ensure proper function. Without allowing the unit this time (6-24 hours) the unit may function for only a short time, and then the compressor will break down from lack of oil.
