We are sorry for any inconvenience caused to you because of this unit. When you are using the portable air conditioner in heat mode, the exhaust hoses must vent outside the room.
This unit uses Heat-Pump technology which reverses the air conditioning cooling cycle by
transferring heat from the outside into the room – this is more energy efficient than traditional
electric heaters that generate heat instead of transferring heat into the room. These properties
make this heater ideal for use in autumn or spring when outdoor temperatures are not severely
cold, or as supplemental heating in colder rooms of your home.
When heating mode is selected the indicator light will shine. Heating is activated only when
the ambient temperature is below 25°C (77°F). In this mode, the desired temperature can be
set between 16°C- 25°C (61°F - 77°F). The Heat pump draws moisture from the air which then condenses into the internal water tank. The unit will pause operation when the tank is full and will restart when the tank has been emptied.
It is recommended to use the heating mode in a room with 50% humidity or lower. Avoid operating moisture-producing products or appliances such as a humidifier or a kettle when using the unit in heating mode.
