- This appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
Setup
Follow these steps for quick and easy installation:
- Placement: Place the portable air conditioner on a firm, level surface in the desired room. Ensure there is at least 30 cm of clear space around the unit for proper air circulation. The unit is equipped with swivel casters for easy movement.
- Window Kit Installation: Assemble the window kit according to your window type (sliding or casement). Extend the window sealing plate to fit the window opening and secure it.
- Exhaust Hose Connection: Attach one end of the exhaust hose to the exhaust adapter. Connect the other end of the exhaust hose to the exhaust outlet on the back of the air conditioner unit. Then, insert the exhaust adapter into the opening of the window kit. Ensure all connections are secure to prevent air leakage.
- Drainage Hose (for Dehumidifier Mode): For continuous drainage during dehumidifier mode, connect the drainage hose to the continuous drain port at the back of the unit and lead it to a suitable drain or container. For cooling mode, the unit typically self-evaporates condensate, but manual draining may be required in high humidity.
