bolts. Noticeably the bolts must not be used less. The installation bracket must be horizontal, and the hole spacing
between the left and right brackets and the air conditioner base should be the same.

with a wrench.
3. When the installation surface is wood and other with not sufficient structural strength, measures such as rein-
forcement, support and reduction vibration should be adopted.
4. Avoid rainy and snowy days as far as possible during installation, and wear seat belts and other protective
measures when installing more than 2 meters in height to ensure the personal safety of installers and avoid
harm to others.
