5.3 Outdoor Unit Installation
5.3.1 Prepare structure for installation
When there is a need to increase the installation
height of the unit, it is recommended that you use the
installation structure shown in the following figure.
Use a rack to support the four corners of the unit
where necessary.
The unit must be installed on a solid longitudinal
base (steel beam frame or concrete). Make sure the
base below the unit is larger than the area shaded in
grey.
Make sure the base where the unit is installed is
strong enough to prevent vibrations and noise.
