Model Number Description
All Trane products are identified by a multiple-character
model number that precisely identifies a particular type of
unit. An explanation of the alphanumeric identification code
is provided below. Its use will enable the owner/operator, in-
stalling contractors, and service engineers to define the op-
Sample Model Number:
Digit Number:
Digit 1,2 - Unit Function
CG = Cold Generator
Digit 3 - Unit Type

5 = 575/50/3
9 = 380/50/3
D = 415/50/3
S = Special
Unit Nameplate
One Mylar unit nameplate is located on the outside upper
right corner of the control panel door. It includes the unit
model number, serial number, electrical characteristics,
weight, refrigerant charge, as well as other pertinent unit
data. A small metal nameplate with the Model Number, Se-
rial Number, and Unit Weight is located just above the Mylar
nameplate, and a third nameplate is located on the inside of
the control panel door.
When ordering replacement parts or requesting service, be
sure to refer to the specific model number, serial number,
and DL number (if applicable) stamped on the unit name-
plate.
Evaporator Nameplate
The nameplate is located on the opposite side of the water
connections. The word "Nameplate" is stenciled on the in-
sulation above the nameplate. To view the nameplate, re-
move the tape over the area and spread the insulation.
Retape the insulation after viewing.
