The 50JZ units dispose of condensate through a 3/4 in. NPT (19.05
mm) female fitting that exits on the compressor end of the unit.
Condensate water can be drained directly onto the roof in rooftop
installations (where permitted) or onto a gravel apron in ground
level installations. Install a field-supplied condensate trap at end of
condensate connection to ensure proper drainage. Make sure that

the outlet of the trap is at least 1 in. lower than the drain condensate
connection to prevent the drain from overflowing. Prime the trap
with water. When using a gravel apron, make sure it slopes away
from the unit.
If the installation requires draining the condensate water away
from the unit, install a field-supplied 2 -in. (50.8 mm) trap at the
