extinguisher available. Read these instructions thoroughly and

follow all warnings or cautions attached to the unit. Consult local

building codes and appropriate national electrical codes (in USA,

ANSI/NFPA70, National Electrical Code (NEC); in Canada, CSA

C22.1) for special requirements.

It is important to recognize safety information. This is the safety-

alert symbol

. When you see this symbol on the unit and in

instructions or manuals, be alert to the potential for personal

injury.

or operation.

WARNING

Electrical shock can cause personal injury and death. Shut

off all power to this equipment during installation. There

may be more than one disconnect switch. Tag all disconnect

locations to alert others not to restore power until work is

completed.
