INTRODUCTION
The 39T series central station air handlers are usually in-
stalled in ductwork; they provide air conditioning at nomi-
nal capacities of 3,500 to 50,000 cfm. The 39T air handler
has a design that allows hundreds of different configuration
possibilities. Each unit is assembled to meet specific job re-
quirements and can be shipped in sections or as a single as-
sembly. These instructions describe how to install, start up,
and service 39T air handlers.
UNIT AND COMPONENT IDENTIFICATION
The 39T comes in two basic configurations; horizontal and
vertical. Using these sections, it is possible to design many
unit variations, including blow-thru units and plenum fan units
with multiple discharges.
Table 1 lists and describes the 4-digit part number pre-
fixes used to abbreviate the names of each 39T component.
Fig. 1 shows an example of the 18-digit model number used
for all 39T units. Each unit’s model number is listed on a
label affixed to the fan section.
The 39T units are configured for blow-thru or draw-thru
operations. Return fan arrangements are also available. See
Fig. 2-7 for recommended section sequences for several ba-
sic unit configuration types. Availability of sections varies
by unit size and unit configuration.
For further information on unit and component identifi-
cation contact your Carrier representative for the AHU (Air-
Handling Unit) Builder™ program.
