light or rain exposure, make sure that heat radiation
from the condenser is not restricted.
2) Ensure that the space around the back and sides is
more than 10cm. The front of the unit should have
more than 70cm of space.

If the outdoor unit is installed on a roof structure, be
sure to level the unit. Ensure the roof structure and
