Methods of Securing: Basic methods of securing are shown right. Avoid blocking or
covering areas aside from those indicated by
the unit to fittings, double-check that the thickness and height of
the fittings, and the number of fixing bolts is correct. (Also refer to
2.4.1 "Mounting to fittings (pg. 21)".)
Heated air is drawn off from the interior of the unit by fans. Before
installation, consider the heat resistance of the wall or other
surfaces behind the unit. Exhaust temperatures can be 30 °C
higher than the outside temperature.
For wall-mounting, do not bundle the cables in a way that will
obstruct ventilation.
