Scotsman NME954 Guide

This parts list contains the service parts and wiring
diagrams for this model. Check the model number
in question to be sure that it is applicable to this
parts list.
Note that these machines have been
manufactured in both 50 and 60 cycle.
60 Hz model numbers end in -3 or -32.
50 Hz model numbers end in -6.
Another change was to the water cooled
condensers. Model numbers ending in A have a
different water cooled condenser than the current
model.
