5. Move the portable air conditioner into place near the wall and insert the exhaust hose into the round adapter. Twist the exhaust hose into the adapter in a clockwise direction. 6. When not in use, remove the exhaust hose from the round adapter and place the round adapter cap over the hole. Notes: 1. The exhaust hose supplied with the portable air conditioner can be extended from 14 1/2” to 59”. However, the shorter the hose, the more efficient the unit will perform. 2. Try to prevent any kinks or bends in the exhaust hose. Kinks or bends may trap exhaust air which can radiate heat into the room or potentially cause the portable air conditioner to shut itself off. 3. The exhaust hose supplied with the portable air conditioner has been specifically designed for this air conditioner. Do not lengthen the hose or replace it with any other hose. Control panel LED indicators 1. “ST” = Set Temperature When this light is lit (when the TEMP. UP or TEMP. DOWN buttons are pressed), the LED display shows the temperature that the unit is set to cool or heat to. 2. “RT” = Room Temperature When this light is lit the LED display shows the current ambient temperature in the room. 3. “LO” = Low Fan Speed This light is lit when the fan speed is on Low. 4. “HI” = High Fan Speed This light is lit when the fan speed is on High. 5. “AUTO” = Auto Mode This light is lit when the Auto mode is selected. The Auto mode is factory preset to maintain an ambient temperature of 73°F. If the ambient temperature is above 73°F, the unit will operate in cooling mode. If the ambient temperature is equal to or below 73°F, the unit will operate in either Fan mode (if the unit does not have a heating function) or in Heating mode (if the unit has a heating function.) 6. “COOL” = Cooling Mode This light is lit when the Cooling mode is operating. 7. “DRY” = Dehumidifier Mode This light is lit when the Dehumidifier mode is operating. The Dehumidifier mode is factory pre-set to one dehumidification setting- and the dehumidification settings cannot be user-altered. 8. “HEAT” = Heating Mode This light is lit when the Heating mode is operating. 9. “TIMER” = Timer On This light is lit when the Timer is on. See below for a description of the Timer. 10. “RUN” = Unit On This light is lit when the unit is on. If this light is flashing, the internal condensate tank is full and the unit has shut itself off. Empty the tank to restart the unit. See the Drainage section for more information on performing this operation. Buttons 1. “TEMP. UP” = Adjusts Temperature Up This button raises the thermostat temperature setting. It only affects the operation of the unit in Cooling mode or Heating mode (if applicable). 2. “TEMP. DOWN” = Adjusts Temperature Down This button lowers the thermostat temperature setting. It only affects the operation of the unit in Cooling mode or Heating mode (if applicable). 3. “SPEED” = Adjusts Fan Speed Press this button to adjust the fan speed between High and Low settings. 4. “MODE” = Toggles Modes Press this button to switch between modes- Auto, Cooling, or Fan/Heating (Units with heating capacity have no Fan mode; units with only cooling capacity have no Heating mode) 5. “TIMER” = Turns Timer On/Off Press this button to activate the timer. Each time you press this button, a time will appear in the LED display (from 1 to 12 hours). The timer can be used to turn the unit on or off.
