▪ 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.

▪ Fasten the unit in place using four foundation bolts M12. It is best 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.
