WARNING: Risk of electric shock. Connect only to a circuit protected by a

This product should be grounded. In the event of an electrical short circuit,
grounding reduces the risk of electric shock by providing an escape wire for the
electric current. This product is equipped with a cord having a grounding wire with a
grounding plug. The plug must be plugged into an outlet that is properly installed
and grounded.
DANGER: Risk of electric shock. Improper use of the grounding plug can
result in a risk of electric shock.
If repair or replacement of the cord or plug is necessary, do not connect the
grounding wire to either at blade terminal. The wire with insulation having an outer
surface that is green with or without yellow stripes is the grounding wire.
Check with a quali ied electrician or service personnel if the grounding instructions
are not completely understood, or if in doubt whether the product is properly
grounded.

NOTICE: Follow local codes when determining the connection type. The temporary
connection may not be permied by local electrical codes.
NOTICE: To avoid possible product malfunction, do not plug in the seat until
instructed.
Preferred Connection
Connect the grounding plug into a grounded outlet that has the same conguration
as the plug.
Temporary Connection
NOTICE: Unless the outlet cover screw is grounded through the house wiring,
aaching the adapter grounding screw tab to the cover screw will NOT ground the
unit. If there is any doubt whether the cover screw is grounded, have it checked by a
qualied electrician or service professional.
A temporary connection with a two-prong adapter may be used where local codes
permit, provided the adapter is grounded.
