Power & Cord

a polarized socket.
• Do not handle the power cord or
plug with wet hands. Keep the plug
and power cord away from liquids.

one way. This is a safety feature to
reduce the risk of electric shock. If
the plug does not fit, reverse the
plug. If it still does not fit, do not
use the plug in that outlet. Do not
bypass this safety feature.

it must be replaced by Arovast
Corporation or similarly qualified
persons in order to avoid an electric
or fire hazard. Please contact
Customer Support (page 10).
