***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 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.
