▪ The height of the foundation must at least be 150 mm from the
floor. In heavy snowfall areas, this height should be increased,
depending on the installation place and condition.
▪ The preferred installation is on a solid longitudinal foundation
(steel beam frame or concrete). The foundation must be larger
than the grey marked area.

to screw in the foundation bolts until their length remains 20 mm
above the foundation surface.

NOTICE
▪ Prepare a water drainage channel around the
foundation to drain waste water from around the unit.
During heating operation and when the outdoor
temperatures are negative, the drained water from the
outdoor unit will freeze up. If the water drainage is not
taken care of, the area around the unit might be very
slippery.
▪ When installed in a corrosive environment, use a nut
with plastic washer (a) to protect the nut tightening part
from rust.
