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.
