ELECTRICAL AND REFRIGERATION • QUICK REFERENCE
***Each outdoor unit is pre-charged with enough refrigerant to charge the indoor
unit and up to 25 ft. of line set. You must adjust the charge if this length varies.
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.
Each system should have a 6-8 inch inverted trap at the condensing unit if mounted
above indoor unit.
Figure A:
Oil trap required at
8-16.4 ft. elevation
(condenser over
evaporator).
