TROUBLESHOOTING Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle). WARNING In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the electrical breaker, and consult authorized service personnel. Merely turning off the unit’s power switch will not completely disconnect the unit from the power source. Always be sure to turn off the electrical breaker to ensure that power is completely off.

OPERATING TIPS Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle). *Heating Performance ● This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating performance is being produced, we recommend you use this air conditioner in conjunction with another type of heating appliance.
OPERATING TIPS Mode operation: AUTO COOLING MODEL ● When the room temperature is 2 °C higher than the set temperature, the mode will switch between Cooling and Drying. ● During the Drying mode operation, the fan will operate at a low speed for a gently cooling effect during which the fan may temporarily stop rotating.
OPERATING TIPS AUTO Restart In Event of Power Interruption ● Should the power supply to the air conditioner be interrupted by a power failure, the air conditioner will restart automatically in the previously selected mode once the power is restored. ● Use of other electrical appliances (electric shaver, etc.) or nearby use of a wireless radio transmitter may cause the air conditioner to malfunction.
