High-Capacity Split Systems
The 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.

Each system is pre-charged with enough refrigerant to charge 25 ft. of
line and the interior unit.
Except for inverter model, Systems having the outdoor unit mounted
above the indoor unit (e.g. basement installations) have the following
additional requirement: For systems with 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.
Figure A.
Example: 25 ft. maximum elevation.
(Oil traps excluded from inverter system.)
