Field Piping, Remote Condenser/Condensing Unit Above Evaporator
NOTES:
1. This is the recommended piping. All piping to be per local and/or state code.
2. Condenser to be no more than 60 feet (18.3 meters) above evaporator.
3. For units built after April 2017, the check valves are included internally in the evaporator
section.
4. Slope horizontal lines downward in the direction of the refrigerant flow, 1/2” (13 mm) for
every 10 feet (3.1 meters) of line length.
5. Inverted trap to extend 8" (203 mm) above the bottom of the condenser coil. Additionally,
inverted traps are needed at the top of every gas line riser.
6. Typical trap height is 5 to 7” (127 to 178 mm), limit the horizontal section of the trap to no
longer than 8" (203 mm).
