-
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

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.
