INFORMATION
CAPABILITIES
Heating Capability
sThis room air conditioner utilizes a heat pump system that absorbs
exterior heat and brings it into a room to be heated. As the ambient
temperature gets lower, heating capability will also lower. In such a
situation, the inverter work to increase compressor rpm to keep the
unit!s heating capability from decreasing. If the unit!s heating perfor-
mance is still unsatisfactory, other heating appliances should be used
to augment this unit!s performance.
sThe air conditioner is designed to heat an entire room so that it may take some time before you feel warm.
Timer operation is recommended for effective preheating ahead of the desired time.
Cooling and Dehumidifying Capabilities
sIf the heat present in a room exceeds the unit!s cooling capacity (for example, if there are many people in
the room or other heating appliances are used), the preset room temperature may not be reached.
CAUTION
PROHIBITION
For the refrigerant charge information, please refer to the outdoor unit installation manual
or specification label.
