SCE275 Service Parts
This is the service parts list for the SCE275. This product was manufactured in both 60 Hz and 50 Hz
models. The model number is different for each voltage. 60 Hz are designated with a -1 or -32 at the end,
for example: SCE275A-1A or SCE275A-32G. 50 Hz models use a -6 at the end, such as SCE275A-6A.
Electrical parts that belong to the different voltages are described as 115/60, 208-230/60 or 50 Hz.
Changes between the A and D series relate to the compressor’s starting components.
The E series changes were to the electrical system of the 50 Hz model.
The F series water cooled models began the use of a different water cooled condenser.
The G series moved the controller to the left side of the chassis.
