Installing the mounting bracket is a key step for your Hisense window air conditioner. The bracket holds the unit safely in place. Follow these instructions carefully to ensure a strong and stable installation.
First, you need to mark the window frame where the bracket will go. Next, secure the bracket properly using the right tools and screws. Each step is important for safety and performance.

Using Weather Stripping
Weather stripping seals small gaps around the air conditioner. It stops cold air from leaking out and hot air from coming in. Use foam or rubber weather stripping for best results.
| Type of Weather Stripping | Best Use | Installation Tips |
| Foam Tape | Sealing flat surfaces | Clean surface before applying |
| Rubber Gasket | Filling irregular gaps | Press firmly for a tight seal |
