13.3. Condensate overflow safety switch con-
nection (CN4F)
The circuit board is equipped with a connection to attach a
condensate safety float switch. The switch should be a normally
closed low voltage rated switch. The switch should be installed in a
location that it can sense a drain blockage causing a rise in water
level. This resulting rise in level will cause it to open. The switch
location is to be determined by the installing contractor. When the
switch opens, it will cause the LEV to close, stopping the cooling
operation. The fan will continue to run and a fault code will be shown
at the controller. Correcting the problem and closing the switch will
be required before normal operation can resume.
SW11
See installation below:
Locate the CN4F connector on the
control board. Carefully remove the
connector with the jumper from the
board. Cut the jumper on the CN4F
connector and wire a normally
closed safety float switch across
the wires. Carefully reinstall the
connector back on the board.
When the Normally Closed Float
Switch opens, the Indoor unit will
turn off.
