NOTE: If the ceiling is not level or even, it is
important that the Cassette is installed level to
ensure correct pump operation and to maintain
fan clearances. Place a carpenter’s level on the
unit. A maximum slope of 1/8” (3mm) over the
length of the chassis toward the condensate
drain is allowed. Any slight discrepancy be-
tween the Cassette and ceiling will be taken up
by the fascia foam seal.
