ELECTRIC GROUNDING INSTRUCTIONS

This appliance (120V ovens only) is equipped with a three-prong (grounding) plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug.

NOTICE

This appliance, when installed, must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 or the Canadian Electrical Code, CSA C22.2, as applicable.

Wiring diagrams are located on the side of the control panel assembly, as well as in this manual (beginning on page 45). Be sure that the input voltage and phase match the requirements shown on the serial plate, which is located inside the lower front panel.

Ovens ordered to operate on 120V power have a three-wire cord. (Double-deck ovens have two power cords, one for each oven.) Each cord has a three-prong plug that fits any standard three-prong grounded receptacle. Single-oven units require a 15 ampere supply, while double-oven units require a 20 ampere supply. (120V ovens shipped to Canada do NOT have factory installed power cords, and must be wired as described below.)

Ovens without a power cord have a terminal block. The electric supply must be brought through the service panel in the rear of the oven and connected to the terminal block. See the wiring diagrams in this manual (beginning on page 45). The unit must be adequately grounded. Use 167°F (75°C) wire for all supply lines.

Ovens are factory-equipped with a two-pole terminal block, located behind a cover plate located on the rear of the oven. To connect the supply wires, remove the cover plate, then route the supply wires and the grounding wire through the strain relief fitting to the terminal block. Insert the supply wires, one each, into the two poles of the terminal block and tighten the screws. Insert the ground wire into the grounding lug and tighten the screw. Re-attach the cover plate.

Three phase units are wired as above, using only two supply wires. The third wire is not used and must be properly terminated.

All units are shipped wired as specified by factory order. Conversion between single-phase and three- phase can be accomplished by referring to phase loading and line amperes chart on wiring diagram for wire size and ampere requirements.
