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.
