The overflow switch is used to interrupt cooling operation
when excessive condensate collects in the drain pan. The
N.O. overflow switch is controlled by K220 and DL46 re
lays, located in the unit control panel. When the overflow
switch closes, 24VAC power is interrupted and after a five-
second delay unit compressors are de-energized. Once
the condensate level drops below the set level, the switch
will open. After a five-minute delay the compressor will be
energized.
