Drill four holes of Ø12mm(0.47in),
45~50mm(1.77~1.97in) deep at the selected

12.2.5.4 Install the main body
Make the 4 suspender through the 4 hanger of
the main body to suspend it. Adjust the
hexangular nuts on the four installation hooks
evenly, to ensure the balance of the body. Use
a leveling instrument to make sure the
levelness of the main body is within ±1°.
Adjust the position to ensure the gaps between
the body and the four sides of ceiling are even.
The body's lower part should sink into the
ceiling for 10~12 mm(0.39~0.47in). In general,
L is half of the screw length of the installation
hook.
Locate the air conditioner firmly by wrenching
the nuts after having adjusted the body's
position well.
