approximately 8.0 gal (30 L) of condensate (water) in the drain tanks, the drain tank switch sends

a signal to the microprocessor. The microprocessor stops all operation of the unit, ﬂashes the

“TANK FULL” LED, indicates “TANK FL” on the LCD and closes the contact of output signal.

accumulates approximately 8.0 gal (30 L) in the drain tanks, the drain tank base plate, which is

supported at its fulcrum, is pushed down in the arrow direction as shown in the ﬁgure below.

contacts #1-#2 of the micro switch. This causes the ground signal at the J103 connector of the

control panel assembly to go open. When the microprocessor detects this event, it shuts the unit

off, ﬂashes the “TANK FULL” LED, indicates “TANK FL” on the LCD and closes the contact of

output signal.

base plate returns to its original position from the tension of the coil spring. Then contacts #1-#2

of the drain tank switch close. This provides a ground to the microprocessor through the J103

connector.
