All Manitowoc ice machines require the ice storage 
system (bin, dispenser, etc.) to incorporate an ice 
deflector.
Prior to using a non-Manitowoc ice storage system 
with other Manitowoc ice machines, contact the 
manufacturer to assure their ice deflector is compatible 
with Manitowoc ice machines.
These numbers are required when requesting information 
from your local Manitowoc Distributor, service 
representative, or Manitowoc Ice.
•  The model and serial number can be viewed by 
pressing the information icon on the touchscreen.
•  The owner warranty registration card.
•  The model/serial number data plate located in the 
evaporator compartment and on the back of the ice 
machine.
The model and serial number displayed on the touchscreen 
must match the data plate for proper operation.
