***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 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.
