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.
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.
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.

ACTUATOR LINKAGE Factory-supplied drives are prealigned and tensioned, however, (OPTIONAL) Carrier recommends that the belt tension and alignment be LINKAGE checked before starting the unit. Always check the drive align- ment after adjusting belt tension. When field installing or replacing sheaves, install sheaves on fan shaft and motor shaft for minimum overhang. -

Figure 53 illustrates the typical piping at the end of every steam supply main. Omitting this causes many field problems and failed coils. Piping practices are outlined in the Carrier System Design Manual, Part 3, Piping Design. Figure 54 shows the typical field piping of multiple coils. - Page 30 a39-4131 a39-2362tf.tif NOTES: 1.
