This portable air conditioner provides cooling, heating, dehumidifying, and ventilation. Before first use, ensure the unit has stood upright for at least 24 hours. The unit requires proper ventilation to the outside via the included exhaust hose. It is compatible with the Smart Life app for remote control.
Product Overview
The unit features a control panel, adjustable air outlet, air filter, recessed handle, air exhaust, drain opening, and wheels for mobility.
Installation
Unpacking: Remove the unit and accessories (exhaust hose, hose connector, window kit adapter, remote control, window kit, drainage pipe) from the carton. Check for damage.


Location: Place the unit on a firm, level surface with at least 50cm of free space around it. Do not install near heat sources, direct sunlight, or in unventilated spaces smaller than 13 m².
Exhaust Hose: Connect the hose connector to one end of the exhaust hose and the window kit adapter to the other. Extend the window kit to fit your window, secure it, and attach the exhaust hose. Ensure the hose is not bent or extended unnecessarily.
Operation
Control Panel: Use the buttons to power the unit, select modes (Cool, Heat, Fan, Dry, Sleep), adjust temperature, set fan speed, and control the timer. The unit defaults to Fan mode upon startup.

Modes:
- Cool: Lowers room temperature (16°C - 32°C).
- Heat: Raises room temperature.
- Fan: Circulates air without cooling.
- Dry: Removes moisture; fan speed is fixed to low.
- Sleep: Adjusts temperature automatically for comfort.
Drainage and Maintenance
Drainage: The unit uses a self-evaporating system. For continuous operation in dry or heating modes, connect the drainage pipe to the drain outlet.
Cleaning: Clean the air filter every two weeks. Switch off the unit, remove the filter, vacuum dust, rinse under running water, and let it air dry completely before reinstalling.
Troubleshooting
If the unit is not operating, check the power connection and water level. If performance is reduced, check for blocked air ducts or open windows. Error codes include E0 (communication fault), E1/E2 (sensor failure), and Ft (high water level).
WiFi Connection
Download the "Smart Life" app. Activate WiFi on the unit (long press the Timer button if needed) and follow the app instructions to add the device.
Storage and Disposal
For long-term storage, drain all water, clean and dry the filter, and store in a dry, ventilated area. Do not dispose of the unit as unsorted municipal waste; use separate collection facilities.
