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.
