PRECAUTIONS TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY
1. Do not attempt to operate this oven with the door open since open-door operation can result
in harmful exposure to microwave energy. It is important not to defeat or tamper with the safety
interlocks.
2. Do not place any object between the oven front face and the door or allow soil or cleaner residue
to accumulate on sealing surfaces.
3. Do not operate the oven if it is damaged. It is particularly important that the oven door close
properly and that there is no damage to the:
(a) Door (bent),
(b) Hinges and latches (broken or loosened) or
(c) Door seals and sealing surfaces.
4. The oven should not be adjusted or repaired by anyone except properly qualified service
personnel.
CAUTIONS
1. Do NOT attempt to tamper with or make any adjustments or repairs to door, control panel
housing, safety interlock switch or any other part of the oven. Do NOT remove outer panel from
oven. Repairs should only be done by a qualified service person.
2. Do NOT operate the oven when it is empty. The microwave energy will reflect continuously
throughout the oven if no food or water is present to absorb energy.
3. If a fire occurs in the oven, touch the STOP/RESET key and LEAVE THE DOOR CLOSED.
Disconnect the power cord, or shut off power at the fuse or circuit breaker panel.
4. Do NOT attempt to dry clothes, newspapers or other materials in the oven. They may catch fire.

Installation, Operation and Care of
MODEL HM1200 MICROWAVE OVEN
SAVE THESE INSTRUCTIONS
GENERAL
Microwave heat is generated inside the food rather than being conducted through the food as in
conventional methods. Time is used to control the amount of heating that occurs.
Microwave energy is absorbed in proportion to the moisture content of the food. The microwave energy
causes water molecules to vibrate at high speeds, resulting in friction (HEAT).
The Model HM1200 produces microwave energy in a magnetron where an electric current is changed
to microwave energy by large magnets. From the magnetron, microwave energy is transmitted to the
oven cavity where it is reflected, transmitted or absorbed.
Microwaves are reflected by metal (on interior walls and the rotating waveguide located underneath the
ceramic tray). This assures that the microwaves are well distributed within the oven cavity and
produces even heating or cooking of foods.
Microwaves pass through paper, glass and plastic much like sunlight shining through a window.
Because these substances do not absorb or reflect the microwave energy, they make ideal food
containers for microwave cooking.
3
Microwaves penetrate the food to a depth of about
especially water, fat and sugar. The excited molecules vibrate at a rate of 2.45 billion cycles per second
which causes friction and produces heat. The internal heating of larger food volumes is done by
conduction. The microwave heat produced in the outer 1
food. Food continues to heat by conduction after microwave production has stopped. Microwaves
dissipate and cannot be stored in food.
RADIO INTERFERENCE
There is a possibility of a small amount of interference with weak broadcast signals if the microwave
oven is too close to a radio or TV or similar equipment. If interference is present, it may be reduced
by: 1) Cleaning the door and sealing surface of the oven, 2) Increasing the separation of the oven from
the receiving device or 3) Using an antenna to obtain stronger signal reception for the receiving device.
/4 to 11/2 inches where they excite molecules –

INSTALLATION
UNPACKING
Immediately after unpacking the microwave oven, check it for possible shipping damage. If this oven
is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.
Before installing the oven, test the electrical service to make sure it agrees with the specifications on
the data plate on the right side of the oven.
– 4 –
LOCATION
Place the oven on a suitable countertop, shelf or table with a smooth, flat and stable surface. Do not
place the oven in a hot or damp area, near a gas or electric range. The microwave oven must not be
located above or next to sources of excessive heat or greasy air. Clean air must be free to flow around
the oven. There is a possibility of a small amount of interference with weak broadcast signals if the
microwave oven is too close to a radio or TV.
It is recommended that the microwave oven be located so the housing can be removed for service.
NOTE: The housing should NOT be removed by anyone except qualified service personnel. A Hobart
service technician is recommended.
The air filter MUST be in place whenever the microwave oven is being operated.
A protective film is used to prevent scratching of the outer case during transportation. Peel the film from
the exterior of the oven before installation or use.
STACKING TWO OVENS — ONE ON TOP OF THE OTHER
Ignore this section if only installing one oven.
Disconnect electrical power cord before stacking ovens. Use the Joint Plate enclosed with the unit.
The maximum stacking height is the total height of the two units. Be sure the oven cavity is empty. Be
sure surfaces where ovens meet are clean and sanitized.
Stack the two microwave ovens. Remove five screws marked (a) and loosen the screw (b) (Fig. 1).
The projection on the Joint Plate must face away from the oven. Place the middle slot on the Joint Plate
over screw (b). Attach the Joint Plate (Fig. 2): Tighten the five screws (a) and tighten screw (b). Make
sure the upper oven is at a safe and workable height.

SEAL OVEN BASE TO COUNTERTOP
Thoroughly clean the bottom perimeter of the microwave
oven and the countertop area around the perimeter of the
microwave oven. Remove the air filter from the front of the
oven (refer to page 15). Apply a bead of silicone sealant
around the entire perimeter of the microwave oven. Smooth
the silicone seal into the crevice with finger or tool to
provide a cove seal. Re-install the air filter after applying
the silicone sealant. This procedure applies equally to a
single oven or to stacked ovens.

ELECTRICAL CONNECTION
The cord and plug of this microwave oven must be connected to a separate circuit rated at 120 Volts,
60 Hertz, 20 Amps, Single Phase. No other appliance should share the circuit with this microwave
oven. If it does, the branch circuit fuse may overload and cause either reduced heating or a blown fuse.
GROUNDING INSTRUCTIONS
This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk
of electrical shock by providing an escape wire for electric current. This appliance is equipped with a
cord having a grounding wire with a grounding plug (Fig. 1). 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.
If it is necessary to use an extension cord, use only
a three-wire extension cord that has a three-blade
PLUG NEMA 5-20P
120 V, 20 A
GROUNDED
OUTLET
NEMA 5-20R
grounding plug and a properly grounded three-slot
receptacle that will accept the plug on the microwave

CLEANING
WARNING: UNPLUG ELECTRICAL POWER CORD BEFORE PERFORMING ANY CLEANING OR
MAINTENANCE.
Keep the inside of the oven clean. If pieces of food or spilled liquids stick to the oven walls or between
the door seal and door surface, they will absorb microwaves and may cause arcing or sparks. Wipe
all spills with a damp cloth. A solution of warm water and mild detergent may be used. Do not use harsh
detergents or abrasive cleaners.
The outside surface of the microwave oven should be cleaned with warm soapy water, then dried with
a soft cloth.
CAUTION: Make sure that no water goes into the rear ventilation openings — this could cause
damage to the oven.
The window in the door should be washed with very mild soap and water. Be sure to use a soft cloth.
Never use window cleaner. The door can be scratched by harsh soap or cleaners.
CLEANING THE AIR FILTER
The Air Filter is located at the front under the door (Fig. 5).
Clean the Air Filter regularly. If the Air Filter becomes clogged with
AIR FILTER
dirt, the oven may overheat, preventing the oven from working
properly.
• Remove the Air Filter from the recess at the bottom below the door
by turning the screw on the right side counterclockwise (use a
dime to fit the slot). Once the screw is loose, slide the Air Filter to
the right to allow the slot on the Air Filter to escape the post on the
Fig. 5
left.
