To install the Hisense window air conditioner, first measure your window opening to ensure it meets the unit's requirements. Gather necessary tools, including a screwdriver and level. Unbox the unit and identify all components, including the side curtains and mounting hardware. Place the unit in the window frame, ensuring it is tilted slightly downward toward the outside to allow for proper condensate drainage. Secure the side curtains to the window frame using the provided screws and seals to prevent air leakage. Once mounted, ensure the unit is stable and level. Plug the power cord into a grounded electrical outlet. Before first use, check that the air filter is correctly installed. Turn the unit on using the control panel or remote, and select your desired cooling mode and fan speed for initial operation.
