1. When the A/C operates with cooling (including auto cooling) and forced cooling mode or dry mode, the
pump will start running immediately and continuously, till stop cooling or dry or no capacity demand.
2. Once the water level increase and up to the control point, LED will alarm and the drain pump open and
continue checking the water level. If the water level falls down below the control point (drain pump delay
close 1 minute) and operate with the last mode. Otherwise the entire system stop operating (including the
