***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.
