SAFETY CONSIDERATIONS
Air-handling equipment is designed to provide safe and reliable
service when operated within design specifications. Improper in
-
stallation, adjustment, alteration, service maintenance, or use can
cause explosion, fire, electrical shock, or other conditions which
may cause personal injury or property damage. Use good judg
-
ment and follow safe practices as outlined below. Consult a quali-
fied installer, service agency, or your distributor or branch for in-
formation or assistance. The qualified installer or agency must us
factory-authorized kits, accessories, or replacement parts when
modifying this product. Refer to individual instructions packaged
with the kits or accessories when installing. To avoid injury to per
-
sonnel and damage to equipment or property when operating this
equipment, use good judgment and follow safe practices as out
-
lined below.
Follow all safety codes. Wear safety glasses, protective clothing,
and work gloves. Have a fire extinguisher available. Read these
instructions thoroughly and follow all warnings or cautions in
-
cluded in literature and attached to the unit. Affix any labels that
ship with the unit or accessory installation instructions to the unit.
Consult local building codes and appropriate national electrical
codes (in U.S.A. ANSI/NFPA70, National Electrical Code (NEC);
in Canada, CSAC22.1) for special requirements.
Recognize safety information. This is the safety-alert symbol .
When you see this symbol on the unit and in instructions or manu-
als, be alert to the potential for personal injury. Under-stand the
signal words DANGER, WARNING, and CAUTION. These
words are used with the safety-alert symbol. DANGER identifies
the most serious hazards which will result in severe personal inju
-
ry or death. WARNING signifies hazards which could result in
personal injury or death. CAUTION is used to identify unsafe
practices which may result in minor personal injury or product and
property damage. NOTE is used to high-light suggestions which
will result in enhanced installation, reliability, or operation.
The following symbols may be seen on the equipment
Unit Label Safety Symbols
WARNING
This symbol shows that the appliance
used a flammable refrigerant. If the
refrigerant is leaked and exposed to an
ignition source, there is a risk of fire.
CAUTION
This symbol shows that the operation
manual should be read carefully.
CAUTION
This symbol shows that the service
personnel should be handling the
equipment with reference to the
installation manual.
CAUTION
This symbol shows that the information
is available such as the operating
manual or installation manual.
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.
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.
