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.
