• After selecting the best location, start installation according to Indoor/Outdoor Unit Installation Diagram.
1. If installing the unit to a concrete base or other solid base,
use M10 or W3/8 bolts and nuts to secure the unit, and
ensure that the unit is fully upright and level.
(The anchor bolt positions are shown in the diagram at

In particular, install the unit at a distance from the
neighbouring building which conforms to regulations
specified by local noise emission regulation standards.
2. Do not install the outdoor unit to the building’s roof.

the rooms of the building, place rubber insulation
between the unit and the installation surface.
