Element Function
Voltage Selection Switch
(Red Side Switch)
• Switch is used to select voltage,
115 Volt or 230 Volt option.
• When switch is in 115 Volt
position the operating voltages
are 100 Volts 50 Hertz and 120
Volts 60 Hertz.
• When switch is in 230 Volt
position the operating voltages
are 220-240 Volts 50 Hertz and
208-230 Volts 60 Hertz.
On-Off Switch • Switch supplies power to all
control functions.
• When switch is in “on” position
the agitation motor, transformer,
