The lightning flash with an arrowhead sym-
bol, within an equilateral triangle, is intended
to alert the user to the presence of uninsu-
lated “dangerous voltage” within the prod-
uct’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 pres-
ence of important operating and mainten-
ance (servicing) instructions in the literature
accompanying the appliance.

main power disconnect for all units.
