WARNING!
Before any service or maintenance is performed on the
unit, be sure to turn the power OFF using the ON/OFF
switch on the front right of the shaker and disconnect the
power cord.
5.3 Changing
Fuses
The unit is designed with a circuit breaker which is used as an ON/OFF switch. There
are two fuses on the rear of the unit (
see Figure 2
). One is to protect the control
circuitry, and the other is to protect the motor circuit. The motor circuit fuse is
mounted in the center of the voltage selector switch.
To remove either fuse:
1. Turn the power off and unplug the power cord.
2. Insert a small flat-bladed screwdriver and turn counter-clockwise until it
disengages and the fuse holder springs free.
3. Check the fuse. If it has failed, replace the fuse with a like fuse, as identified in
the Spare Parts List. Spare fuses are supplied with the unit.
5.4 Changing
Voltages
Innova 4000 is set to the appropriate line voltage prior to shipment. The voltage
selector switch, however, is a universal power-entry device which can be reset to adapt
to worldwide power requirements. The voltage selector switch is located on the rear
left of the unit (
see Figure 2
), directly above the power cord connection. If it is
necessary to set the unit to a different voltage, use the following procedure:
1. Set the circuit breaker (located on the right side of the unit) to OFF.
2. Disconnect the unit from the power source.
3. Using a small flat-bladed screwdriver, rotate the center portion of the switch until
the fuse is disengaged. Remove the fuse.
4. Using a larger flat-bladed screwdriver or a small coin, rotate the center portion of
the switch to the desired voltage. The indicator is at the top of the switch.
5. Replace the fuse and holder.
6. Check that the proper power cord is available for the voltage selected.
7. Plug the power cord into the power cord connection on the unit, then plug it into the
power source.
8. Set the circuit breaker to the ON position.
The unit is ready for operation.
