***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 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.
