1. Basic space required
A space of at least 250 mm is necessary at the right side for inlet air.
Taking servicing, etc. from the right side into account, a space of about
450 mm should be provided, the same as at the front and back.
2. When there is an obstruction above the unit
3. When unit is surrounded by walls
Note:
• Wall heights (H) of the front and the back sides shall be within
overall height of unit panel.
• If the panel height is exceeded, add the “h” dimension to L
1
, L
2
and L
3
.

Example:
When h is 100,
the
L
1
dimension becomes 450 + 100 = 550 mm.
4. Continuous installation
• Space required for continuous installation:
When installing several units, leave the space between each unit
considering passage for air and people.
• Open in the two directions.
• In case wall height (H) exceeds overall height of unit, add “h” dimension
(h = wall height <H> – overall height of unit) to * marked dimension.
