The unit comes with an 11,500 BTU (ASHRAE 128) portable heating unit delivering a dual option solution for comfort year-round. The thermostat cools 450 sq. ft. spaces as low as 61°, heats up to 88° F, and dehumidifies up to 90 pints every 24 hours. You have everything you need to install this unit quickly with an air slider bracket, hose inlet and outlet, 2 locking screws, exhaust hose, drain hose, and foam seal included. Circulate air with high efficiency using the auto air swing mode and pick between 3 speeds— 202 cfm at high, 178 cfm at medium, and 166 cfm at low. Rolling wheels and a compact size allows it to be transported seamlessly with almost no hassle. The unit was made for use in sliding and double hung windows only and not for crank windows. Though this machine is ETL safety certified, it must be set on a level, smooth floor that is strong enough to support its weight for the lowest vibration and noise possible while in use. Be sure all your space’s windows and doors are shut when using it for best circulation, attach the hoses to ensure proper operation, and allow 3 minutes for the compressor to begin after microprocessor control settings have been changed. 2 AAA remote control batteries needed (sold separately).
