Safety Procedures

• Always Disconnect power cord before attempting to work on or to clean
equipment. Turning the switch off is insufficient as the power remains live
to the cabinet and can be a hazard.

• Route the power cord so that it is not likely to be walked on or pinched by
other appliances.

• Do not overload outlets with too many appliances. This can result in fire
or electrical shock.

• Disconnect plug when the appliance will be idled for a long period of time.

• Do not attempt to service this unit yourself as removing covers may
cause unnecessary exposure to dangerous voltage.

• Never connect the unit to a power source while standing in water. Wet
hands and wet floors should be avoided when connecting any electrical
appliance to a power outlet.

• When a replacement part is required, always insist on factory authorized
parts.
