IMPORTANT SAFETY INSTRUCTIONS
WARNING
To avoid risk of fire in the oven cavity:
a. DO NOT overcook food. DO NOT place paper, plastic,
or other combustible materials inside the oven if these
materials are not intended for cooking by the
manufacturer.
b. Remove wire twist – ties from paper or plastic bags
before placing bag in oven.

CLOSED, turn oven off and disconnect the power cord,
or shut off power at the fuse or circuit breaker panel.
d. DO NOT use the cavity for storage. DO NOT leave
paper products, cooking utensils, or food in the cavity.
WARNING
Liquids such as water, coffee, or tea can be overheated
beyond the boiling point without appearing to be boiling due
to surface tension of the liquid. Visible bubbling or boiling
when the container is removed from the microwave oven is
not always present. THIS COULD RESULT IN VERY HOT
LIQUIDS SUDDENLY BOILING OVER WHEN A SPOON
OR OTHER UTENSIL IS INSERTED INTO THE LIQUID.
To reduce the risk of injury to persons:
i. Do not overheat the liquid.
ii. Stir the liquid both before and halfway through
heating/cooking.
iii. Do not use straight-sided containers with narrow
necks.
iv. After heating/cooking, take extensive care removing
the container from the cavity.
v. Use extreme care when inserting a spoon or other
utensil into the container.
CAUTION
To avoid risk of personal injury or property damage observe
the following guidelines:
1. Do not deep fat fry in oven. Fat could overheat and be
hazardous to handle.
2. Do not cook or reheat eggs in shell or with an
unbroken yolk. Pressure may build up and erupt.
Pierce yolk with fork or knife before cooking.
3. Pierce skin of potatoes, tomatoes, and similar foods
before cooking with microwave energy. When skin is
pierced, steam escapes evenly.
4. Do not place popcorn bags in this oven as they may
ignite.
5. Do not use regular cooking thermometers in this oven
when cooking in microwave or combination mode. Most
cooking thermometers contain mercury and may cause
an electrical arc, malfunction, or damage to oven.
6. Do not use metal utensils in oven except as
recommended by Duke Manufacturing. Heat food in
containers made of glass or china if possible.
7. When cooking with paper, plastic, or other combustible
materials, follow manufacturer’s recommendations on
product use. Never use unapproved material or items
that are not rated for this oven or not approved by Duke
Manufacturing. When oven temperature is high,
material may ignite. Oven temperature is set between
minimally 90°C to 260°C (200°F to 500°F) in
convection mode. Verify plastic, paper or other
combustive materials are recommended by the
manufacturer to withstand the maximum oven
temperature.
8. Do not use paper towels, which contain nylon or other
synthetic fibers. Heated synthetics could melt and
contaminate food.
9. Do not heat sealed containers or plastic bags in oven.
Food or liquid could expand quickly and cause
container or bag to break. Pierce or open container or
bag before heating. Plastic can melt/ignite and vapors
may pose a health hazard.
10. Racks, utensils, containers, and oven surfaces may
become very hot during or after use. Use utensils or
protective clothing, like pan grips or dry oven mitts,
when necessary, to avoid burns.
11. Do not unplug oven immediately after use. Internal fan
must cool oven to avoid damage to electrical

temperature settings, fan speeds (Variable
1 to 9) and microwave power. It has some
statistical and service diagnostics.
2. OVEN DOOR and CAVITY
The oven door and cavity are constructed
from stainless steel and must be kept clean
(see Care and Cleaning instructions).
3. CONVECTION AIR
The unit has two blower systems (left and
right) for distributing the air on the product.
The blower system can be operated at
different speeds (10% interval) for higher
efficiency of cooking, browning, etc. The jet
openings must be kept clean and free of
debris (see Care and Cleaning instructions).
4. DOOR
The door is pulled downwards and towards
you to open. The door is designed with
interlocks for microwave safety. The door
should NOT be used to support heavy
dishes. It must be kept clean. (See Care
and Cleaning instructions).
5. DOOR SEALS
The seals prevent the microwave barrier in
the door from accumulating debris. They
should be kept clean and checked regularly
for signs of damage. At the first sign of wear
they should be replaced by Duke approved
Service Agent.
6. AIR INLET
The large air inlet at the top of the cavity is
part of the convection system. It must be
kept free from obstruction. It will not allow

MAIN FEATURES
7. COOLING LOUVERS
The louvers prevent electrical components
inside the oven from overheating by
supplying cold air. Although the oven has
only a clearance requirements to the left
adjacent wall with 1.25cm/0.5in, these
louvers should be cleaned from obstructions
between the rib openings and preferably
have access to open air.
8. EXHAUST VENT
The exhaust vent is at the rear of the oven.
This enables steam to escape and prevents
build up of condensation. It will not allow
microwave energy to escape into the
environment.
9. COOLING FANS

INSTALLATION
Unpacking Oven
• Inspect oven for damage.
• Report any dents or breakage to source of
purchase immediately. Do not attempt to
use oven if damaged.
• Remove all materials from oven interior.
• If oven has been stored in extremely cold
area, wait a few hours before connecting
power.
Radio Interference
Microwave operation may cause interference to
radio, television, or a similar oven. Reduce or
eliminate interference by taking the following
precautions:
• Clean door and sealing surfaces of oven
according to instructions in Care and
Cleaning section.
• Place radio, television, etc. as far as
possible from oven.
• Use a properly installed antenna on radio,
television, etc. to obtain stronger signal
reception.
Oven Placement
• Do not install oven next to or above source
of heat, such as pizza oven or deep fat fryer.
This could cause microwave oven to operate
improperly and could shorten life of electrical
parts.
• Install oven on level countertop surface.
• If provided, place warning label in a
conspicuous place close to microwave oven.
• Outlet should be located so that plug is
accessible when oven is in place.
A. Allow at least 15.2cm/6in of clearance on top.
B. No clearance is required at the back.
C. A clearance of 1.3cm/0.5in is necessary between
side panels and next adjacent walls.
D. A clearance of 7.5cm/3in is required to operate two
ovens side by side or the clearance to an adjacent
similar heat source.
E. Proper airflow around oven cools electrical
components. With restricted airflow, oven may not
operate properly and life of electrical parts is
reduced.
F. Install combination oven so oven bottom is at least
93cm/3ft above floor.
G. When stacking ovens, use ONLY the approved
Duke Manufacturing stacking frame.
Oven Clearances
Line Interference
The switching operation of this microwave oven
can cause voltage fluctuations on the supply
line. The operation of this oven under
unfavorable voltage supply conditions can have
adverse effects. This device is intended for the
connection to a power supply system with
maximum permissible system impedance, Z
max
,
of 1.1 at the interface point of the user’s
supply. The user has to ensure that this device is
connected only to a power supply system, which
fulfills the requirement above. If necessary, the
user can ask the public power supply company
for the system impedance at the interface point.
As the oven has no ON/OFF switch, it must
be connected to a breaker that is conform to
national regulations.
WARNING
To avoid risk of electrical shock or death,
this oven must be grounded and the plug
must not be altered. Improper grounding can
result in the risk of electric shock.
Grounding Instructions
This oven MUST be grounded. Grounding
reduces risk of electric shock
by providing an escape wire
for the electric current if an
electrical short occurs. This
oven is equipped with a cord
having a grounding wire with a grounding plug.
The plug must be plugged into an outlet that is
properly installed and grounded.
Consult a qualified electrician or service agent if
grounding instructions are not completely
understood, or if doubt exists as to whether the
oven is properly grounded.
Do not use an extension cord. If the product
power cord is too short, have a qualified
electrician install a proper outlet. This oven
should be plugged into a separate circuit with the
electrical rating as provided in product
specifications (available on Duke Manufacturing
website). When the combination oven is on a
circuit with other equipment, an increase in
cooking time may be required and fuses can be
blown.
