height difference.
(m) Installation space
1)
Walls surrounding the unit in the four sides are not acceptable.

There must be a 1-meter or larger space in the above.
3)
When more than one unit are installed side by side, provide a 250mm or wider interval between them as a service space.
In order to facilitate servicing of controllers, please provide a sufficient space between units so that their top plates can
be removed easily.
4)
Where a danger of short-circuiting exists, install guide louvers.
5)
When more than one unit are installed, provide sufficient intake space consciously so that short-circuiting may not occur.
6)
Where piling snow can bury the outdoor unit, provide proper snow guards.
