Make note of the following when installing the unit in
areas affected by cold weather or snow:
Avoid directly exposing the air outlet or air inlet to
the wind.
The local maximum snowfall should be taken into
consideration when deciding the foundation height
of ODU.
The foundation or base height of the ODU is
required to be the expected maximum snowfall
thickness h0 + 300mm, preventing the snow from
contacting the bottom of the unit.
