INTRODUCTION
The 39M Series central station air handlers are usually in-
stalled with ductwork; they provide air conditioning at nominal
capacities of 1500 to 55,000 cfm. The 39M air handler design
allows hundreds of different configuration possibilities. Each
unit is assembled to meet specific job requirements and can be
shipped in sections or as a single assembly. These instructions
describe how to install, start up, and service 39M air handlers.
SAFETY CONSIDERATIONS
The 39M air-handling equipment is designed to provide
safe and reliable service when installed and operated within de-
sign specifications. To avoid injury to personnel and damage to
equipment or property when operating this equipment, use
good judgment and follow safe practices as outlined below.
DANGER
NEVER enter an enclosed fan cabinet or reach into a unit
while the fan is running.
Failure to heed this warning will result in severe personal
injury or death.
WARNING
LOCK OPEN AND TAG the fan motor power disconnect
switch before working on a fan. Take fuses with you and
note removal on tag.
LOCK OPEN AND TAG the electric heat coil power
disconnect switch before working on or near heaters.
Failure to follow these safety precautions could lead to
severe personal injury or death.
WARNING
CHECK for adequate ventilation when welding, cutting, or
performing any other fume producing activities inside
air-handling unit cabinet or plenum so that fumes will not
migrate through ductwork to occupied spaces.
WHEN STEAM CLEANING COILS be sure that the area
is clear of personnel.
SECURE fan drive sheave with a rope or strap before
working on a fan to ensure that rotor cannot freewheel.
PREVENT unauthorized entry into the unit; leave safety
latches in place on access doors except during installation
or service procedures. After accessing a section, replace
and tighten the safety latch.
DO NOT work on dampers until their operators are
disconnected.
BE SURE that fans are properly grounded before working
on them.
Failure to follow these safety precautions could lead to per-
sonal injury.
WARNING
CHECK the assembly and component weights to be sure
that the rigging equipment can handle them safely. Note
also the centers of gravity and any specific rigging
instructions.
PROTECT adjacent flammable material when welding or
flame cutting. Have a fire extinguisher at hand and ready
for immediate use.
Failure to follow these safety precautions could lead to
severe personal injury and/or equipment damage.
WARNING
DO NOT remove access panel fasteners until fan is
completely stopped.
Pressure developed by a moving fan can cause excessive
force against the panel and toward personnel.
Failure to heed this warning could lead to personal injury
and/or equipment damage.
CAUTION
DO NOT ground equipment to fan assembly when
welding. Damage to fan bearings could result.
DO NOT restore power to unit until all temporary
walkways inside components have been removed.
NEVER pressurize equipment in excess of specified test
pressures.
Failure to follow these safety precautions could lead to
equipment damage.

UNIT AND COMPONENT IDENTIFICATION
The 39M air handler comes in two basic configurations;
horizontal and vertical. Using appropriate sections, it is
possible to design many unit variations, including blow-thru
units and plenum fan units with multiple discharges. See Fig. 1
and 2 for nameplate label identification. Figures 3-11 show an
example of the model number used for 39M unit sections and
components. Each unit’s model number is listed on a label af-
fixed to the fan section. Section and major component level
part numbers are listed and affixed to each individual compo-
nent section.
For further information on unit and component identifica-
tion contact your Carrier representative for the AHUBuilder®
program. Refer to the 39M Product Data catalog for more in-
formation on individual component sections. Refer to Fig. 12-
14 and Tables 1-25 for component data.
WARNING
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and gog-
gles and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from sys-
tem using both high-pressure and low pressure ports.
c. Traces of vapor should be displaced with nitrogen
and the work area should be well ventilated. Refrig-
erant in contact with an open flame produces toxic
gases.
d. Cut component connection tubing with tubing cutter
and remove component from unit. Use a pan to catch
any oil that may come out of the lines and as a gage
for how much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when nec-
essary. Oil can ignite when exposed to torch flame.
Failure to follow these procedures may result in personal
injury or death.
WARNING
1. Improper installation, adjustment, alteration, service,
or maintenance can cause property damage, personal
injury, or loss of life. Refer to the User’s Information
Manual provided with this unit for more details.
2. Do not store or use gasoline or other flammable va-
pors and liquids in the vicinity of this or any other
appliance.
What to do if you smell gas:
1. DO NOT try to light any appliance.
2. DO NOT touch any electrical switch, or use any
phone in your building.
3. IMMEDIATELY call your gas supplier from a neigh-
bor’s phone. Follow the gas supplier’s instructions.
If you cannot reach your gas supplier, call the fire
department.
IMPORTANT: The installation of air-handling units and
all associated components, parts, and accessories which
make up the installation and subsequent maintenance shall
be in accordance with the regulations of ALL authorities
having jurisdiction and MUST conform to all applicable
codes. It is the responsibility of the installing contractor to
determine and comply with ALL applicable codes and
regulations. Field-supplied motors should be Underwriters
Laboratories (UL) or Canadian Standards Association
(CSA) approved. Field wiring must comply with National
Electrical Code (NEC) and all local requirements.
