This label may appear on the bottom of the unit due to space
limitations.

The lightning flash with an arrowhead symbol,
within an equilateral triangle, is intended to alert
the user to the presence of uninsulated “dangerous
voltage” within the product’s enclosure that may
be of sufficient magnitude to constitute a risk of
electric shock to persons. 

The exclamation point within an equilateral
triangle is intended to alert the user to presence of
important operating and maintenance (servicing)
instructions in the literature accompanying the
appliance.

Attention: 

Installation should be performed by

qualified service personnel only in accordance with
the National Electrical Code or applicable local
