This maintenance should be carried out by SAMSUNG local technician. Besides keeping the remote controller clean by means of a soft damp cloth, no maintenance is required by the operator. During longer periods of standstill, e.g. during summer with a heating only application, it is very important NOT TO SWITCH OFF THE POWER SUPPLY towards the unit. Switching off the power supply stops the automatic repetitive movement of the motor in order to prevent it from getting jammed. WARNING This product contains fluorinated greenhouse gases covered by the kyoto Protocol. Refrigerant type: R410A GWP(1) value: 1975 (GWP = global warming potential) • Periodical inspections for refrigerant leaks may be required depending on European or local legislation. Please contact your local dealer for more information.
