• Operation Improvement
− Quiet mode to provide quiet operation.
− Powerful mode to reach the desired room temperature
quickly.
− Ionizer control for generating negative ion in discharge
air.
− 24-hour timer setting.
• Serviceability Improvement
− Removable and washable Front Panel.
• Environmental Friendly
− R410A, which does not contain chlorine, is used as its
refrigerant, so there is no danger of damage to the
ozone layer in stratosphere.
