Instructions / Assembly

Disconnect all power to unit before installing or servicing. More
than one disconnect switch may be required to de-energize the
equipment. Hazardous voltage can cause severe personal injury or
death.
If removal of the blower assembly is required, all disconnect
switches supplying power to the equipment must be de-energized
and locked (if not in sight of unit), so the field power wires can be
safely removed from the blower assembly. Failure to do so can
cause electrical shock, resulting in personal injury or death.
Because of possible damage to equipment or personal injury,
installation, service, and maintenance should only be performed
by trained, qualified service personnel. Consumer service is
recommended only for filter cleaning/replacement. Never
operate the unit with the access panels removed.
These instructions are intended as an aid to qualified,
licensed service personnel for proper installation, adjustment,
and operation of this unit. Read these instructions thoroughly
before attempting installation or operation. Failure to follow these
instructions may result in improper installation, adjustment,
service or maintenance possibly resulting in fire, electrical shock,
property damage, personal injury or death.
