User Tips
Portable Air Conditioners are ideal for spot cooling. They house the compressor, condenser, and evaporator in a compact unit. Air is dehumidified and cooled, while a flexible Exhaust Hose sends heat outside. A window venting kit is included, and no permanent installation is needed, making the unit easy to move and offering flexible air conditioning.
Auto Evaporation System
The unit automatically evaporates condensate through the Exhaust Hose. Drainage tank emptying is generally not needed, except in humid conditions. Always read and follow instructions carefully.
For optimal efficiency in air conditioner or dehumidifier mode, keep doors and windows closed. If using only the fan function, an open window may improve air circulation.
Operation Modes Visualized:
- Cooling, Heating*, and Dehumidifying Operation: The unit is connected to a window venting kit with an exhaust hose extending outside.
- Fan Operation: The unit operates without an exhaust hose connected to a window.
Important: Before installing, place the unit UPRIGHT for 1 hour to stabilize the refrigerant. Manually adjust the air vent at the top to direct airflow.
- Follow installation instructions to set up the unit.
- Plug the unit into a properly grounded circuit. DO NOT plug into an extension cord.
