SAFETY CONSIDERATIONS
Air-handling equipment is designed to provide safe and
reliable service when operated within design specifications. To
avoid injury to personnel and damage to property or equip-
ment, use good judgment and follow safe practices as outlined
below when installing and operating this equipment.
NEVER REACH INTO a unit while the fan is running.
LOCK OPEN AND TAG the fan motor power disconnect
switch before working on unit. In addition, remove the
fuses and take them with you after noting this on tag.
DISCONNECT ALL POWER before attempting any
installation or service. More than one power source may be
supplied to a unit. Power to remote mounted control
devices may not be supplied through the unit.
CHECK THE WEIGHT of assembly and components to
be sure that rigging equipment can handle them safely.
NEVER PRESSURIZE a coil with a non-liquid for leak
testing. A dangerous burst may occur.
DO NOT STEAM CLEAN coils until you are sure all per-
sonnel are clear of the area.
Failure to follow these warnings will result in severe per-
sonal injury or death.
The following contains general installation instructions for
the 42BHE,BVE fan coil units. (See Fig. 1.) Refer to the unit-
wiring diagram installed on the blower housing or specific
manufacturer literature for any other type of factory-mounted
controls.
