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-
eration, specific components, and other options for any spe-
cific unit.
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.
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.
Compressor Nameplate
The nameplate for the “Scroll” compressors are located on
the compressor lower housing.
Evaporator Barrel Nameplate
(EVP Chiller Applications Only)
The nameplate is located on the top of the evaporator near
the supply-end tube sheet. The word “Nameplate” is sten-
ciled on the insulation. To view the nameplate, remove the
tape over the area and spread the insulation. Retape the in-
sulation after viewing.

Hazard Identification
Warnings are provided through-
out this manual to indicate to installing contractors, opera-
tors, and service personnel of potentially hazardous situa-
tions which, if not avoided, COULD result in death or seri-
ous injury.
Cautions are provided throughout
this manual to indicate to installing contractors, operators,
and service personnel of potentially hazardous situations

jury.
Unit Description
All air cooled condensing units are designed for outdoor in-
stallations with vertical air discharge. These units may be
installed on a flat roof or placed on a concrete slab at
ground level.
Before shipment, each unit is leak-tested, evacuated, a Ni-
trogen holding charge is added, and the controls are tested
for proper operation.
The condenser coils are aluminum fin, bonded to copper
tubing. Copper-fin coils are optional. Louvered condenser
grilles for coil protection are standard.
