Installation Requirement

Bearing

You can install the product in an unfixed or a wall-mounted way based on your needs. The wall-

mounted way can save a large amount of space.

If the product is installed in an unfixed way, use the designated hanger or holder. If you want to

use a self-made hanger or holder, ensure that the bearing capacity of it is at least four times of
the weight of the product, and the product is installed stably on it.

If the product is installed in a wall-mounted way, the bearing capacity of the surface for

installation must be at least four times of the weight of the product. If the surface for installation
is the wall or the ceiling of a building, the surface must be made of solid bricks, concrete or
other materials with equal intensity. If the product is installed on a surface made of loose
material such as an old brick wall, wood plank wall, solid brick wall, or a metal or non-metal
structure surface, or a surface with a thick decoration layer, take necessary consolidating
measures to ensure that the product is stably installed.

Ventilation

If the product is installed inside a wall or a cabinet, in addition to the preceding requirements,
the ventilation area around the bottom, top and two sides must be at least 50% of the
sealing surface to ensure proper ventilation.

3

Note: 1. When the product is installed in a wall-mounted way, the screws need to be installed

deeper than 10 mm in the way.

2. Do not block ventilation vents.

4

Use a level to locate the holes in
horizontal line and mark with pencil
where the holes will be located. Then drill
holes in the wall.

Insert wall plugs into the mounting holes.
Push the self-tapping screws through the
bracket into the wall plugs and tighten the
screws.

Attach the mounting arms to
the back of screen with the
screws.

Hang the screen and let it settle
into the bracket. Ensure that it is
firmly in place.
