Step 6—Provide for Condensate Disposal
NOTE: Ensure that condensate-water disposal methods comply
with local codes, restrictions, and practices.
The units dispose of condensate through a 3/4 in. NPT 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 installa-
tions. 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-pan condensate
connection to prevent the pan 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. trap at the condensate
