Wolf Convection Steam Oven 3

Welcome
Congratulations on your choice of a Wolf convection
steam oven.
The legacy of the “combination oven” goes back decades,
to innovative restaurant chefs in America and Europe who
embraced the gentle combination of air movement with
superheated steam to achieve superior results in menu
offerings from breads and roasts to delicate fishes,
seafood and vegetables.
European home cooks wanting the highest degrees of
freshness, flavor and vitamin preservation for their families
also embraced the technology, and today the home steam
oven is a standard fixture of the residential kitchen in
many European countries.
Now Wolf combines the benefits of convection heat and
steam heat for the most innovative home steam oven on
the market today. Virtually any dish prepared in a conventional oven, range or microwave can also be prepared in
the Wolf convection steam oven—with more control over
the finished product. The convection movement of hot air
ensures consistent heating and browning and eliminates
odor transfer while steam adds moisture at just the right
times and amounts—for the perfect end results.
• Moistness and flavor are retained so no additional oil,
basting or sauces are necessary.
• Vitamins, texture, shape, size and color are preserved.
• Risks of overcooking are reduced and messy boil-
overs eliminated.
• Breads, bagels, bakery and pastry can be proofed,
baked and crisped with steam.
• Meats defrost gently and evenly without any hot spots.
• In Wolf gourmet mode, a sensor automatically adjusts
cooking time to the type and amount of food being
cooked, preventing under- or overcooking.
• Smart timer functions are like an extra pair of hands,
cooking food that’s ready to serve when you need it—
even when you're not in the kitchen to start and stop
the oven.
The more you use your Wolf convection steam oven, the
more you will reap these and many more benefits.
Enjoy greater confidence in the kitchen with more ease
and professional results than ever before. This guide has
been thoughtfully arranged to help you to learn the
features and benefits of your new oven, and to be as
enjoyable and productive as possible. Please read it, keep
it handy for reference and follow the following safety
precautions.

Do not operate any appliance with a damaged cord
or plug, or after the appliance malfunctions or has
been damaged in any manner. Return appliance to
the nearest authorized service facility for examination, repair or adjustment.
•
The use of accessory attachments not recommended by the appliance manufacturer may cause
injuries.
•
Do not use outdoors.
•
Do not let cord hang over edge of table or counter,
or touch hot surfaces.
•
Do not place on or near a hot gas or electric burner,
or in a heated oven.
•
Extreme caution must be used when moving an
appliance containing hot oil or other hot liquids.

to “off”, then remove plug from wall outlet.
•
Do not use appliance for other than intended use.
•
Save these instructions.
Safety Instructions 5

SAFETY PRECAUTIONS
CHILD SAFETY
•
Plastic and polystyrene can be dangerous for
children. Keep these packaging materials away from
children.
•
The appliance is designed for use by adults who are
familiar with these operating instructions. Children
are often unable to recognize the danger of electrical
appliances. Ensure proper supervision and do not
allow children to play with the appliance.
•
Use the childproof locking feature outlined on
page 9.
FIRE HAZARDS
•
Never flambé or cook food using excessive fats.
•
Never use the appliance to dry animals, textiles or
paper.
•
Do not use the oven as a room heater or humidifier.
•
Only use the probe supplied. Do not submerge it in
water or clean it in the dishwasher.
•
Installation and operation should only occur in a
room with an ambient temperature between 41°F
and 95°F. If frost develops, residual water left in the
pumps could freeze and cause damage.
•
Any repairs, modifications or manipulations to the
appliance, especially any electrically live parts,
should only be carried out by the manufacturer, its
customer service department or similarly qualified
persons. Incorrectly done repairs may cause serious
injury, damage the appliance and fittings, and affect
the functioning of the appliance.
•
If the appliance is not working properly or in case a
repair is needed, follow the instructions given in the
troubleshooting guide. Please contact Wolf customer
care if necessary.
•
Only original equipment manufacturer parts may be
used.
•
If the appliance is visibly damaged, do not use it.
Contact Wolf customer care.
•
If the appliance is not operating property, disconnect
it from the power supply immediately.
Safety Instructions 6
SAFETY PRECAUTIONS
FIRE HAZARDS
•
Ensure the main cables of other electrical appliances
do not get caught in the door of the oven, which
could damage the electrical cable insulation and
create a fire hazard.
•
If the main cable of the appliance is damaged it must
be replaced by a Wolf factory certified service
provider.
•
Ensure there are no foreign bodies in the cooking
space before closing the appliance door.
•
Never store objects in the cooking space. This could
pose a danger if the appliance were accidentally
turned on. Do not store food, temperature-sensitive
or inflammable materials (e.g. cleaning agents, oven
sprays, etc.) in the cooking space.
BURN HAZARDS
•
The appliance gets very hot when in use. The oven
door, especially the glass, can also get hot. Do not
touch the oven door. Keep children away.
•
The appliance will remain hot for some time after it
is turned off and will cool down slowly to room
temperature.
•
Steam may escape from the cooking space when
the door is opened. Do not put your hands into the
cooking space if there is steam inside of it.
•
Water in the water tank can be hot and can present a
scalding hazard.
•
Overheated fat and oil can easily catch fire. Heating
oil in the cooking space to sear meat is dangerous
and should not be done. Never try to extinguish
burning oil or fat with water. Smother fire or flame or
use dry chemical or foam-type extinguisher.
•
Do not pour spirits (e.g. brandy, whisky, schnapps,
etc.) or extracts with alcohol over hot food.
•
Do not leave the appliance unsupervised when
drying herbs, bread, mushrooms, etc. If the foodstuff
dries out too much it can pose a fire hazard.
•
If you notice smoke possibly coming from the appliance itself or from inside the cooking space, keep
the appliance door closed. Disconnect the appliance
from the power supply.
•
Do not heat unopened food containers as build-up
of pressure may cause the container to burst and
result in injury.
•
Accessories get hot in the cooking space. Always
wear dry oven mitts or other dry, protective gloves or
use oven cloths.
•
Do not put fingers in the door hinges, which could
cause injury if the appliance door is moved. Particular care should be taken when children are around.
•
Only leave the appliance door open in the at-rest
position. An open appliance door poses a danger of
tripping or injury. Do not sit or rest on the appliance
door or use it as a storage surface.
•
Keep oven vent ducts unobstructed.
•
Hot steam may escape from the steam vent during
operation. Use care when opening the door to allow
steam to escape before removing or replacing food.

Using the Temperature Probe
The probe monitors your food’s temperature and
announces when it has reached a temperature considered
“done” and safe for consumption. Using the probe also
helps to maintain ideal tenderness.
The internal temperatures shown in the chart below are
the USDA recommendations for safe food consumption.
Your desired doneness may vary.
INTERNAL TEMPERATURE
DONENESS INTERNAL TEMP
BEEF, LAMB AND VEAL
Rare 140°F (60°C)
Medium Rare 145°F (65°C)
Medium 160°F (70°C)
Well Done 170°F (75°C)
PORK
Well Done 170°F (75°C)
POULTRY
Well Done Breast 170°F (75°C)
Well Done Thigh 180°F (80°C)
Well Done Stuffing 165°F (75°C)
POSITIONING THE TEMPERATURE PROBE
1) Insert the probe into the thickest part of the meat so
that the tip is in the center of the meat. Bury the entire
metal shaft into the dish, or as much as is possible. To
maintain accuracy, avoid touching bone or fat with the
probe as they conduct heat faster.
2) Insert the plug end of the probe into the socket located
on the right interior oven wall behind the metal flap.
3) Ensure probe cable is neatly tucked inside of the oven
interior. Close the oven door.
SETTING THE PROBE TEMPERATURE
1) Select the operating mode and cooking space temper-
ature.
2) With the probe positioned and plugged in, press the
TEMP button until the display reads ‘Probe Temperature’.
3) Turn the control knob to set the probe temperature
based on the desired level of doneness and press to
select. Probe temperature appears in the left digital
display when the temperature reaches 85°F or higher.
