Offset uncomfortable temperatures outside with the 10,000 BTU SACC/CEC (14,000 BTU ASHRAE) Portable Air Conditioner. This Portable Air Conditioner was built to rapidly cool or heat and dehumidify office and home spaces up to 450 sq. ft. in size. Simply toggle fan speed and airflow settings to your desired level with this unit’s easy-to-use electronic LED controls. Move it to another location inside your living or working space or another location altogether and quickly install with its side handles, smooth rolling castors, included window adaptor, and hose. The air conditioner packs the cooling and heating power to keep a large living room, small apartment, bedroom, classroom, or dorm comfy and cozy. Install this unit in sliding and double hung windows only (not crank windows). You can get the quietest, safest, lowest vibration possible by placing it on a level, smooth floor that is firm enough to hold the unit. For the best results, keep all windows and doors closed while the Portable Air Conditioner is in use, connect the included pipe to make sure it works properly, and wait 3 minutes for the compressor to start operating after the microprocessor control settings have been changed.
