ELECTRICAL CONNECTIONS
Before making electrical connections, verify that the electrical service agrees with the specifications
on the data plate on the lower right side as you face the oven.
Grounding Instructions
This appliance must be grounded electrically. In the event of an electrical short circuit, grounding
reduces the risk of electrical shock by providing an escape wire for the electric current. This appliance
is equipped with a cord having a grounding wire with a grounding plug. The plug must be connected
to an outlet that is properly installed and grounded.
WARNING: IMPROPER USE OF THE GROUNDING PLUG CAN RESULT IN A RISK OF ELECTRIC
SHOCK.
Consult a qualified electrician or service person if these grounding instructions are not completely
understood or if there is doubt that this appliance is properly grounded.
Have a qualified electrician install a suitable outlet near the appliance. If you must use an extension
cord, use only a three-wire extension cord that has a three-blade grounding plug and a properly
grounded three-slot receptacle that will accept the plug on the microwave oven. The marked rating of
the extension cord MUST be equal to or greater than the electrical rating of the microwave.
The cord and plug of the Model HM1600 must be connected to a separate circuit. No other appliance
should share the circuit with the microwave oven. If it does, the branch circuit fuse may overload and
either cause the oven to heat slower than expected or blow the fuse.
The oven is built to operate on two different voltages (220 – 240 V or 208 V). Be sure that the voltage
selector connector (on the back of the oven) is set for your power supply (Fig. 2). Using a higher voltage
is dangerous and may result in overheating of the electrical components thus shortening their life
expectancy or possibly causing a fire or other accident. Using a lower voltage will lower the power
output of the oven, resulting in slower heating of the food. Hobart is NOT responsible for damage
resulting from the use of the oven with other than specified voltage.
The oven is shipped from the factory for 208 V connection. To adjust for 220 – 240 volt operation:
• WARNING: UNPLUG THE POWER CORD.
• Remove the voltage adjustment cover located on the back of the oven. Do not remove any other
parts from the oven.
• Remove the connector from the white socket and rotate the connector 180 degrees and plug into
the black socket.
• Reattach the voltage adjustment cover to the cabinet.
208 Volt — Plug connector into WHITE socket. 208 / 60 / 1 — 17.0 Amp.
220 – 240 Volt — Plug connector into BLACK socket. 230 / 60 / 1 — 15.4 Amp.
