***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.
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.
Figure A.
Example: 25 ft. maximum elevation.
