TIPS FOR BEST USE

Connect the cassette to a dedicated power socket protected by a

magnetothermal circuit breaker of suitable capacity for the electrical input

of the appliance.

When the water cassette starts or stops, especially in the heating mode,

creaking sounds may be heard. This is caused by thermal expansion of the

unit parts.

Mist may sometimes be produced by the cassette for a few seconds in the

cooling mode. This is quite normal and is caused by the difference in

temperature between the air flowing out of the appliance and the air in the

room.

Do not place heat sources near to the cassette as this could deform the

plastic parts.

Do not insert objects into the air intakes or outlets when the cassette is in

operation.

Do not place objects in a position that may obstruct the passage of the air

into the unit as this could affect appliance efficiency.

ENERGY SAVING

Do not open or close doors and windows too often. Constant exchange of

heat with the outside affects the working of the appliance.

Do not set too high a temperature (in the heating mode) or too low (in the

cooling mode).

Do not install the appliance where it is exposed to direct sunlight.

Use the TIMER for the timed switching on of the appliance, to avoid the

cassette operating needlessly while you are out of the house.

Use the SLEEP function during the night.

ROUTINE MAINTENANCE

ATTENTION!

Turn off the automatic circuit breaker before carrying out any cleaning

operations. Use a cloth dampened with lukewarm water (max 40°C) and

mild detergent to clean the cassette. Do not use solvents or harsh detergents.

OPENING THE PANEL

To open the grille turn the plastic screws present on the grille by 90° (1/4 of a

turn) (fig. 49) and gently pull the panel downwards without forcing the hinges

that fasten it to the appliance. Attention: to make cleaning easier, the grille may

be removed completely since the receiver panel is positioned on the fixed frame

of the unit (see fig. 50).
