The arrow ▼ indicates the front of the unit in
the above figures.
A≥1000mm, 500mm≥B≥100mm.
The dimensions in the above figures provide
sufficient space for operation and
maintenance under normal operating
conditions (refrigeration mode at an outdoor
temperature of 35°C).
If the outdoor temperature is higher and
ventilation short circuiting may occur, choose
the most suitable dimensions by calculating
the return air flow.
Keep the inlet and outlet of each ODU open
and avoid interference.
If there is an obstacle in the space over the
unit, the four sides of the unit should be open.

Unit: mm
If there are no walls in front of or behind the unit,
it is necessary to reserve a space of 1000mm on
both sides.
If the front wall is higher than 1500mm, a space
of at least (1000 + (h2)/2) mm is required at the
front.
If the rear wall is higher than 500mm, a space of
at least (1000 + (h1)/2) mm is required at the
back.
When the space above the unit is less than
1500mm, an air ducting device shall be installed
to prevent ventilation from short circuiting.
When the space over the unit is greater than
1500mm, an air ducting device shall be installed
if the air circulation is not smooth at the top of the
unit.
Do not install the ODU in a confined space.
