Note: Only the "MODEL NUMBER" is replaced for F-450MAH-C.
See the nameplate for electrical and refrigeration specications. This nameplate is located
on the rear panel.
Since this nameplate is located on the rear panel of the icemaker, it cannot be read when
the back of the icemaker is against a wall or against another piece of kitchen equipment.
Therefore, the necessary electrical and refrigeration information is also on the rating label,
which can be easily seen by removing only the front panel of the icemaker.
We reserve the right to make changes in specications and design without prior notice.
