SAFETY CONSIDERATIONS
Air-handling equipment is designed to provide safe and reliable
service when operated within design specifications. To avoid inju-
ry to personnel and damage to equipment or property when oper-
ating this equipment, use good judgment and follow safe practices
as outlined below.
INTRODUCTION
Unit Identification
The 39S units are identified by the 18-digit part number listed on
the serial plate. The part number describes all component, coil,
motor, drive, and control selections.
For further information on unit and component identification, con-
tact your Carrier representative for the AHUBuilder
®
program.
Refer to the 39S Product Data catalog for more information on in-
dividual component sections. Refer to Tables 1-4 and Fig. 1-21 for
component data.
DANGER
Failure to follow these warnings may result in personal injury
or death.
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 discon-
nect switch before working on or near heaters.
WARNING
Failure to follow these warnings may result in personal injury
or equipment damage.
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 mi-
grate 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 pan-
els 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 per-
sonnel.
DO NOT work on dampers until their operators are discon-
nected.
BE SURE that fans are properly grounded before working on
them.
CAUTION
Failure to follow these warnings may result in personal injury
or equipment damage.
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 pres-
sures.
PROTECT adjacent flammable material when welding or
flame cutting. Use sheet metal or asbestos cloth to contain
sparks. Have a fire extinguisher at hand and ready for immedi-
ate use.
