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.

pan connections. Attach the connector as described above and route drain line. Any vertical drain pan
openings must be covered to eliminate air loss which will decrease the capacity of the unit.
