Warranty Information
5-year limited warranty covering parts and labor, with extended coverage for sealed system components.
Cooling and Dehumidifying Operation: Keep doors and windows closed for optimal efficiency.
Fan Operation: An open window can improve air circulation.
Before Installation: Place the unit UPRIGHT for 20 minutes to allow refrigerant to stabilize.
Power Control: Turns the unit on and off.
Mode Control: Choose from Cool, Dehumidify, and Fan.
In Cooling Mode, adjust fan speed and temperature (61°F - 89°F).
In Dehumidifying Mode, if room temperature is above 77°F, fan speed can be adjusted; otherwise, it's preset to LOW. For efficiency, do not connect the exhaust hose and allow warm air to return to the room. Continuous drainage is recommended.
In Fan Mode, air circulates without cooling.
Fan Speed Control: High, Medium, Low.
Timer Control: Set auto turn-off (while running) or auto turn-on (while in standby) from 1-24 hours.
Temperature/Timer Set Controls: Adjust timer and thermostat. Default display is room temperature. Temperature adjustable only in cool mode.
Note: Pressing both "<" and ">" buttons simultaneously toggles between Celsius and Fahrenheit.
Warning Light: Flashes if the internal water tank is full, preventing operation until drained.
Important: Wait 3 minutes before switching the unit back on after turning it off.
Remote Control: Functions mirror the touch screen panel. Do not place in direct sunlight.
Battery Installation: Use 2 AAA batteries, noting polarity. Remove batteries if not in use for over a month.
