Scotsman CME506 A-D Service Manual

CME256 or CME506 or CME656 or CME806 Service Parts

This parts list contains service part information for 8
basic models, plus 4 different electrical
configurations. The complete model number will

be needed to identify the correct part.

Model Series Changes (code at the end of the model
number)

C series - changes to the front & side panels

•

D series - changes to the top panel and to the

•

compressor starting components
E series - new side panels and 2 TXVs with

•

check valves for the CME506
F series - new water cooled condensers

•

Electrical Codes are located at the end of the model
number (voltage/hertz/phase):

-1 is 115/60/1

•

-32 is 208-230/60/1

•

-3 is 208-230/60/3
