This Nameplate is located on the upper right hand side of 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.
