Note: Minimum airflow limits apply to units with hot water or electric heat only. There is no minimumairflow limit on cooling on units. Maximum airflow limits are to help prevent
moisture carryover.

Note: Trane recommends these maximum gpms to help
prevent erosion and/or noise problems. However lower
gpms may be necessary, depending on the
systemdesign, to avoid exceeding close-off pressure
limit of the control valve.
