4.4 DRAIN FORCE
4.4.1 SEQUENCE OF OPERATION
While the machine is turn on, there is water that need to be evacuated between each cycle. There are 2
possible outlet water, one is if the ice in the storage bin melts (#1) and the other is when the production
time ends, the water electrovalve opens and fills the water tray(#2) to renovate the water. The excess of
water goes out by the overflow (#3) to the drain force water reservoir (#4).
When the water reservoir is full of water covering the 2 electrodes (#5), the pump (#6) turns on and
evacuates water for 5 seconds. After 5 seconds, the pump turns off if the electrodes are not covered by
the water, otherwise, the pump will start again for 5 seconds.
In case that the system does not work for any issue, the water will flood the ice bin. There is a ventilation
tube (#7) that allows the system to remove any air that may remain in the water reservoir. The Vent tube
must be always over the mouth of the front door (#8).
In case that the pump works for 5 minutes continuously, it will stop for 5 seconds automatically in order
to refrigerate.
The system has a way to evacuate the water inside the water reservoir in a manual way. There is a plug
(#9) in one of the plastic tube, by retiring this plug, it is possible to evacuate all the water.
Also, the system has a Check valve(#10) that does not allow the water to came back to the water
reservoir.
