GROUNDING INSTRUCTIONS: This
appliance must be grounded. In the
event of malfunction or breakdown,
grounding will reduce the risk of
electric shock by providing a path of
least resistance for electric current.
If using a power supply cord, the plug
must be plugged into an appropriate
outlet that is properly installed and
grounded in accordance with all local
codes and ordinances.
If using a direct wire connection, this
appliance must be connected to a
grounded metal, permanent wiring
system; or an equipment-ground
conductor must be run with the circuit
conductors and connected to the
equipment-ground terminal or lead on
the appliance.
WARNING - Improper connection of
the equipment-grounding conductor
can result in a risk of electric shock.
Check with a qualified electrician or
serviceman if you are in doubt as to
whether the appliance is properly
grounded. Do not modify the power
supply cord plug. If it will not fit the
outlet, have a proper outlet installed by
a qualified electrician.
