IMPORTANT
Over-tightening the drain connection could result in drain pan breakage and failure.
The secondary connection should be connected to a separate drainage system. Run the secondary drain
so the occupants will be able to notice water flowing through the secondary drain indicating a blockage in
the primary drain. Optional use for the secondary is a primary drain line overflow switch (provided by
others). This device will shut the cooling operation unit down in the event of a primary drain line blockage.
See wiring section for connecting this device.

eliminate air loss which will decrease the capacity of the unit.
