Utilising eco-friendly R290 refrigerant which is non toxic and kinder to the ozone layer, the new Climateasy 12R2 portable air conditioner model from Koolbreeze is designed for smaller rooms requiring cooling or heating all year round. The Climateasy 12R2 delivers 12000BTU (3.5kW) of cooling and 11000BTU (3.2kW) of heating power and provides air conditioning, heating, dehumidifying and cooling fan functions in a single compact unit. The built-in automatic evaporative technology uses any collected moisture to cool the unit before it is eliminated through the exhaust duct leaving no internal water tank to empty during normal operation. Please Note:The Climateasy 12R2 model also benefits from HEPA filters as standard. Installation of the optional HEPA filter will automatically disable Cooling, Heating, Dehumidifying and Auto Modes. If the HEPA filter has previously been installed or your unit has been delivered with the filter pre-installed by the factory you must remove it to re-enable these functions. If the filter is installed the unit will only operate in fan mode. The HEPA indicator LED on the operator panel will illuminate if the filter is correctly installed. Product must be vented outside when used in AC or heater mode.
