1. While the cooling operation is active, remove the cap from the water opening, and use a water pump or other source to gradually add, at least between 600 and 800cc of water, through the water supply opening.
Check the draining action of the system by listening to the sound of the drain pump. If the sound of the drain pump changes from continuous to intermittent, the drain system is functioning normally.
2. After checking the system, replace the water supply opening cover.
