For reference only. The NEMA plugs listed above may not be allowed in every area. Consult local
electrical codes before installing any electrical plugs or receptacles. FETCO does not assume any
responsibility for the electrical wiring setup outside the actual equipment.
Units configured for the U.S. and Canada are either 120VAC or dual voltage (120/208-240VAC).
Dual voltage means that the control components operate on 120VAC, and the heating elements
operate on 208-240VAC. A neutral wire is required. Dual voltage does not mean that the unit can
be adjusted to operate on either 120VAC or 240VAC.
