110/220 Volt Operation
Operation in either 110 VAC or 220 VAC is easily achieved. If the voltage indicated on the fuse box
does not match the voltage you are operating in, the fuse must be changed. Open the fuse box door to
remove and rotate the fuse holder. Make sure the voltage indicted, when the fuse box door is closed,
matches your operation voltage. Refer to Figure 1.
