The TCL H12W35W window air conditioner is designed for installation in standard double-hung windows with a width between 26 and 36 inches and a minimum opening height of 14.5 to 16 inches. The unit includes an installation kit containing side curtains and mounting hardware. Ensure the unit is installed with a slight downward tilt toward the outside to allow for proper condensate drainage. Secure the unit firmly to the window frame using the provided brackets and screws to prevent movement. Once mounted, ensure the side panels are fully extended and sealed to prevent air leaks. Plug the unit into a grounded 3-prong electrical outlet. After installation, allow the unit to sit upright for at least 24 hours before the first power-on to ensure the compressor oil settles.
