SAFETY CONSIDERATIONS
Air-handling equipment is designed to provide safe and reliable service when operated within design 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.
LOCK OPEN AND TAG the fan motor power disconnect
switch before working on a fan. Take fuses with you and
note removal on tag. Electric shock can cause personal
injury or death.
LOCK OPEN AND TAG the electric heat coil power disconnect switch before working on or near heaters.
Failure to follow these warnings could lead to personal
injury or death.
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.
CHECK for adequate ventilation so that fumes will not
migrate through ductwork to occupied spaces when welding or cutting inside air-handling unit cabinet or plenum.
WHEN STEAM CLEANING COILS be sure that the area
is clear of personnel.
DO NOT attempt to handle access covers and removable
panels on outdoor units when winds are strong or gusting
until you have sufficient help to control them. Make sure
panels are properly secured while repairs are being made to
a unit.
DO NOT remove access panel fasteners until fan is completely stopped. Pressure developed by a moving fan can
cause excessive force against the panel which can injure
personnel.
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 warnings could result in personal
injury or equipment damage.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

CAUTION
Unit Identification — The 39S units are identified by
INTRODUCTION
the 18-digit part number listed on the serial plate. The part
SECURE drive sheaves with a rope or strap before working on a fan to ensure that rotor cannot free-wheel.
DO NOT restore power to unit until all temporary walkways inside components have been removed.
NEVER pressurize equipment in excess of specified test
pressures.
PROTECT adjacent flammable material when welding or
number describes all component, coil, motor, drive, and control
selections.
For further information on unit and component identification, contact your Carrier representative for the AHUBuilder
program. Refer to the 39S Product Data catalog for more information on individual component sections. Refer to Tables 1-4
and Fig. 1-13 for component data.
flame cutting. Use sheet metal or asbestos cloth to contain
sparks. Have a fire extinguisher at hand and ready for
immediate use.
Failure to follow these warnings could result in personal
injury or equipment damage.

DIMENSIONS (in.)
LEGEND
*"C1" dimension is for standard unit. "C2" dimension is for double wall units.
†Sizes 13 and 17 are twin blowers. Dimension "E" is to closest blower. Dimension "F" and "G" are typical for both fan outlets.
NOTES:
1. Measurements shown in inches.
2. Unit hand is determined by looking into the filters in same direction as airflow. Right hand unit shown for reference.
