MDT5N25 & MDT5N40

OPERATION: Ice Vending

Dispensing takes place when the

 

Touch Free sensor’s infrared beam

 

bounces back to the sensor from a

 

container placed directly in front of

 

it.

 

If the container is in front of the

 

Touch Free sensor on the left side,

 

the ice dispensing vane will rotate

 

and sweep ice over the ice

 

dispensing chute: ice will continue

 

to discharge out this chute as long

 

as the vane is turning. It stops

 

when the dispensing vane stops.

 

If the container is in front of the

 

Touch Free sensor on the right

 

side, the inlet water valve will open

 

and water will flow into the

ICE CHUTE

container.
