ing to the difference between the setting

18°C~30°C)
3. HEAT MODE : The unit operates accord-
ing to the difference between the setting

*Prevention against cold wind : For about
3~5 minutes after initial operation (thermo
control or "de-ice"), the indoor fan will
either not operate or operate very slowly,
then switch to the selected fan speed. This
period is to allow the indoor unit's heat-
exchanger to prewarm until emitting
warm air.
