The Floor Standing and Ceiling Cassette models
are ideal for light commercial applications and
work well in large, open spaces. The Ceiling
Cassette is a useful alternative when floor space
is limited.
The outdoor unit for both models operate on
high-voltage (230/208) power and models one
or two compressors, depending on the size.

NOTE: Systems having the outdoor unit mounted above the indoor unit (e.g. basement installations) have the following
additional requirement: For systems with maximum elevation of 25 ft. (see chart above and Figure A), refrigerant lines
must be oil-trapped between 8 ft. and 16.4 ft. of elevation. For systems with elevation of greater than 25 ft. (see chart
above), refrigerant lines must be oil-trapped at least every 16.4 ft. of elevation.
†
Dual-Zone: Exterior unit has sufficient refrigerant for charging two indoor coils and a 25 ft. line set per indoor unit.
Tri-Zone: Exterior unit has sufficient refrigerant for charging three indoor coils and a 25 ft. line set per indoor unit.
