NOTICE
Equipment Damage!
All vent-lines must be equipped with a drip leg of
sufcient volume to hold the expected accumulation
of water and or refrigerant. The drip leg must be
drained periodically to assure that it does not over-
ow and allow uid to ow into the horizontal por-
tion of the vent-line. Trane assumes no responsibility
for equipment damage caused by insufcient drain-
age of the drip leg.
8. Consult local regulations and codes for any addition-
al relief line requirements and refer to CFC-Guide-2.
