operates continue until the above modes stop.

switch, the controller will make LED flashing to give warning signal, and at the same time forces compressor to
stop and the drain pump start. The water level will be checked continuously. If the water level falls to warning
water level, the warning signal will disappear( the drain pump delay 1 minute to be off), compressor starts again(3

after 3 minutes, the whole unit stops(including drain pump) and warning signal can"t disappear. It can"t recover
unless out of power.
