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.

10 - TROUBLESHOOTING GUIDE

• If the air conditioner is not working properly, carry out the following checks before calling the After-Sales Department.
• If the problem persists, contact the After-Sales Department.
