The BLU09 9,000 BTU portable air conditioner delivers an instant cooling relief for your home or work place. Suitable for rooms up to 20 square metres. The BLU09 does not have a heating function.
Complimentary Window Sheet for Casement Windows: Now supplied with a high quality window sheet that has been especially designed for UK Outward/Inward Opening Windows so there is no need to buy a separate window sheet.
R290 Refrigerant: Uses natural high efficiency R290 with zero greenhouse emissions. The natural refrigerant is non-toxic, eco friendly and also offers energy savings.
Self Evaporating Function: Reduces the need to regularly remove water. The unit recycles approximately half of the condensed water and uses it to cool off the inner cooling coils, which allows the unit to run more efficiently. It then disperses, or evaporates, the remaining water, along with the hot air, via the hot air duct. This cuts out any unnecessary water collecting inside the unit or in an outside container.
Easy to Set Up: Simply set up the hose kit provided, place out of the window opening, plug and play in a few simple steps. The complimentary window seal kit can be used with outward or inward opening UK casement windows to seal your space & prevent heat gains.
Additional Features for your Convenience: Window Sheet for Casement Windows, Remote Control with LED Display to switch between Modes, Set Temperature & View °F & °C. Louvers allow maximum cooling efficiency, easy-roll omnidirectional castors help you move your "BLU09CO" wherever it is needed most.
Sound Pressure Level: 49-53dBA. Sound Power Level: 62 - 64dBA. The sound pressure level is the pressure disturbance in the atmosphere measured using predefined conditions such as the location of the equipment and environmental conditions - the sound pressure is ultimately what our ears hear.
The BLU09 does not have a heating function as it is cooling only. Please note, the BLU09 should not be plugged into a multiway extension lead as this can result in a whiny noise. It can also affect the unit's performance. If you have to use an extension lead, please use a 1 gang heavy duty extension lead to ensure the unit can run effectively.
