9 - ADVICE ON COMFORT AND ENERGY SAVING
AVOID:
• Blocking the appliance's air inlet and outlet grilles. If they are
blocked, the appliance will not work satisfactorily and it may
be damaged.
• Allowing the sun to shine directly into the room when the
appliance is operating in "air conditioning" mode. Use
shutters or curtains.
