SAFETY CONSIDERATIONS
The 39M air-handling equipment is designed to provide safe and
reliable service when installed and operated within design
specifications. To avoid injury to personnel and damage to equip
-
ment or property when operating this equipment, use good judg-
ment 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 discon-
nect 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-han-
dling 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 latch-
es 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 discon-
nected.
BE SURE that fans are properly grounded before working on
them.
Failure to follow these safety precautions could lead to person-
al 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.
