unit should be plugged into a fused or circuit breaker protected 20 amp, 120
All models utilize standard 120-volt power supply. The unit should be plugged into a fused or
circuit breaker protected 20 amp, 120 volt, 60 Hz circuit.
Table 1 shows the amperage requirements for the specific models. If an extension cord is
required, refer to Table 2 for the proper 3-conductor heavy-duty cord required.
Do not exceed the amperage ratings of the extension cord. Undersized extension cords result in
excessive drops in voltage, which cause the electric motors to generate excessive heat. This
condition results in inefficient motor operation and premature motor failure, WHICH WILL VOID
