***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 Figure A), refrigerant lines must be oil
trapped between 8 ft. and 12 ft. of elevation.
For systems with elevation of greater than 25 ft. Refrigerant lines must be oil trapped at least every 12 ft.
of elevation.
* Each system should have a 6-8 inch inverted trap at the condensing unit if mounted above indoor unit.
Figure A.
Example: 25 ft. maximum elevation.
