• The BYCQ140E2W1W has white insulations. Be informed that the formation of dirt on white insulations is visibly stronger and that it is consequently not advised to install the BYCQ140E2W1W decoration panel in environments exposed to concentrations of dirt.
  When using the BYCQ140E2W1W decoration panel it is advised to change the filter cleaning display indications on the remote controller from light to heavy. Changing the setting to heavy corresponds to filter cleaning display indications in case of higher contamination of the air. Refer to the indoor unit installation manual under paragraph “setting air filter sign” or “field setting”, depending on the type of indoor unit.
