Each system is pre-charged with enough refrigerant to charge 25 ft. of line and the interior 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.
