What should I do when the water full indicator lamp lights up?

When the water full indicator lamp lights up, it means the water level in the inner tray has reached its maximum height and the tank must be drained. Remove the rubber plug from the drainage hole at the bottom of the unit (Hole B) and connect a drain hose to empty the tank. If the water pump is damaged, you can also remove the rubber blockage at the bottom of the unit to drain the water outside. (Page 47)
