ELECTRICAL CONNECTIONS
ELECTRICAL SHOCK HAZARD
Disconnect power before installing or servicing appliance. Before turning
power ON, be sure all controls are in the OFF position. Failure to do so can
result in death or electrical shock.
ELECTRICAL GROUNDING
This appliance must be grounded. Grounding reduces the risk of electric shock in the event of
a short circuit. Grounding through the neutral conductor is prohibited for new branch circuit
installations (1996 NEC), mobile homes, and recreational vehicles, or in an area where local
codes prohibit it. This oven has been setup at the factory for a 4-wire connection.
Improper grounding will cause malfunctions in the unit and create a shock hazard condition.
ELECTRICAL CONNECTION
The appliance must be on its own dedicated circuit - 240 VAC, Single Phase, 60 Hz, or 208
Volt, 60Hz, with a current rating as shown in the Model listing on page 2.
NOTE: FOR USE WITH 208 V, 60 HZ SUPPLY VOLTAGE, SEE “CONNECTING TO 208
VOLT CIRCUIT” on page 10.
For hook-up of the oven you will need to have an approved junction box installed where it
will be easily reached through the front of the cabinet where the oven will be located.
The oven has 3 ft. [91 cm] of flexible conduit. DO NOT shorten the conduit. Allow of 2 to 3
ft. [61-91 cm] of slack so that the oven can be moved if servicing is ever necessary.
For both US and CANADA installations: This appliance is
equipped with copper lead wires and must be connected to
copper wires only. Improper connection of aluminum house
wiring can result in a fire or shock hazard. Use only connectors
designed and certified for connecting to aluminum wire, and
installed by a qualified electrician.
