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 end of 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
•
H series - color change
•
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
•
-6 is 250/50/1
