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.
