SAFETY CONSIDERATIONS

Air-handling equipment is designed to provide safe and reli-
able 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 dis-
connect switch before working on or near heaters.
Failure to follow these warnings could lead to personal
injury or death.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

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 weld-
ing 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 com-
pletely 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.
CAUTION
SECURE drive sheaves with a rope or strap before work-
ing on a fan to ensure that rotor cannot free-wheel.
DO NOT restore power to unit until all temporary walk-
ways inside components have been removed.
NEVER pressurize equipment in excess of specified test
pressures.
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
immediate use.
Failure to follow these warnings could result in personal
injury or equipment damage.
