RECOMMENDATION

Use the Installer’s Guide packaged with the coil for the physical installation of the coil.
IMPORTANT:
To ensure proper operation, make sure the airflow direction arrow marked on the coil cabinet matches the furnace airflow.
NOTE: Water blow-off could occur in certain installation position if the airflow setting exceeds the maximum values listed. Please refer to “maximum airflow setting” label or literature shipped with unit.
If a coil is part of the total system installation, use the Installer’s Guide packaged with the furnace, outdoor section, and thermostat for physically installing those components.
