2. For vertical rises, the installing contractor must install a trap at the bottom of the vertical rise and no
greater than 5 feet horizontal distance from the compressor discharge connection of the evaporator
section.
3. For vertical rises greater than 20 feet, the installing contractor must install mid-rise trap(s) every 15 feet
or evenly spaced points along the vertical lift.
4. An inverted trap is required at the top of the vertical rise and no greater than 3 feet horizontal distance
from the condenser coil. The inverted trap must extend a 7-1/2” above the bottom of the condenser
coil.
• Liquid lines do not require traps.
• See Figure 5 - Remote Condenser Above Evaporator for typical trapping requirement for each refrigerant
circuit.
