COOKWARE SUGGESTIONS

NOTE: Make sure the utensil does not touch the interior walls during cooking.

Use these utensils for safe microwave cooking and reheating:

• Glass ceramic

• Heat-resistant glass

• Microwave-safe plastics

• Microwave-safe paper plates

• Microwave-safe pottery, stoneware and porcelain

• Browning dish (Do not exceed recommended preheating time. Follow manufacturer’s directions.)

These items can be used for short time reheating of foods that have little fat or sugar in them:

• Wood, straw, wicker

DO NOT USE:

• Metal pans and bake-ware

• Dishes with metallic trim

• Non-heat-resistant glass

• Non-microwave-safe plastics (margarine tubs)

• Recycled paper products

• Brown paper bags

• Food storage bags

• Metal twist-ties

NOTE: To check if a dish is safe for microwaving, place the empty dish in the oven and microwave on HIGH for 30

seconds. If the dish becomes very hot, DO NOT use it for microwaving.

RADIO OR TV INTERFERENCE

Should there be any interference caused by the drawer microwave to your radio or TV, check that the drawer

microwave is on a different electrical circuit, relocate the radio or TV as faraway from the drawer as feasible or check

position and signal of receiving antenna.

CLEANING AND CARE

Stainless Steel Surface: The exterior should be wiped often with a soft damp cloth and polished with a soft dry

cloth to maintain its beauty. There are also a variety of products designed especially for cleaning and shining the

stainless exterior of the oven. We recommend that the cleaner be applied to a soft cloth and then carefully used on

the stainless exterior rather than sprayed directly on to it. Follow package directions carefully.

Front Side of Drawer: Wipe the window on both sides with a soft damp cloth to remove any spills or spatters.

Metal parts will be easier to maintain if wiped frequently with a soft damp cloth. Avoid the use of spray and other

harsh cleaners as they may stain, streak or dull the door surface.

Touch Control Panel: If desired, the touch pads may be deactivated before cleaning. See the CONTROL LOCK

information on page 3-8 of section 3, Theory of Operation, of this manual. Wipe the panel with a cloth dampened

slightly with water only. Dry with a soft cloth. Do not scrub or use any sort of chemical cleaners. Close door and fol-

low directions on page 3-8 for turning CONTROL LOCK off. Touch STOP/CLEAR.

Interior: Cleaning is easy because no heat is generated to the interior surfaces; therefore, there is no baking and

setting of spills or spattering. To clean the interior surfaces, including drawer sealing surfaces, wipe with a soft damp

cloth. Do not use abrasive or harsh cleaners or scouring pads. For heavier soil, use mild soap; wipe clean with a

soft damp cloth. Do not use any chemical oven cleaners.

Drawer Guides: Remove the food crumbs from the drawer guides. Wipe with a soft dry cloth in order to keep the

drawer Microwave opening and closing smoothly.

Odor Removal: Occasionally, a cooking odor may remain in the drawer microwave. To remove, combine 1 cup

(250 ml) water, grated peel and juice of one lemon and several whole cloves in a 2-cup(500 ml) glass measuring

cup. Boil for several minutes using 100% power. Allow to sit in the drawer microwave until cool. Wipe interior with a

soft cloth.

INSTALLATION INFORMATION

Below are the Product Safety Labels used in this manual. This section of the manual covers some of the installation

issues that a service technician may need to know when servicing a Wolf Drawer Microwave. If additional installa-

tion information is needed, after reviewing this section of the manual, please refer to the installation guide or contact

the Wolf Appliance Customer Service Department.

• TO REDUCE RISK OF TIPPING, DRAWER MICROWAVE MUST BE SECURED BY A PROPERLY INSTALLED

ANTI-TIP BLOCK.

• STEPPING, LEANING OR SITTING ON DRAWER MAY RESULT IN SERIOUS INJURIES AND CAN ALSO

CAUSE DAMAGE TO DRAWER MICROWAVE.

• FOR SAFETY CONSIDERATIONS DO NOT INSTALL DRAWER IN ANY COMBUSTIBLE CABINETRY, WHICH

IS NOT IN ACCORD WITH THE STATED CLEARANCES AND DIMENSIONS PROVIDED IN PRODUCT INSTAL-

LATION INSTRUCTIONS.

• NEVER LEAVE CHILDREN ALONE OR UNATTENDED IN THE AREA WHERE A DRAWER MICROWAVE IS IN

USE. NEVER LEAVE DRAWER OPEN WHEN MICROWAVE IS UNATTENDED.

• DO NOT USE DRAWER MICROWAVE AS A STORAGE SPACE. THIS CREATES A POTENTIALLY HAZ-

ARDOUS SITUATION. CHECK THAT THE TIME-OF-DAY IS IN THE DISPLAY. IF NOT, TOUCH STOP/CLEAR

TO PREVENT UNINTENDED USE.

• THIS DRAWER MICROWAVE MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL

CODES.

• DO NOT USE AN EXTENSION CORD. IF POWER SUPPLY CORD IS TOO SHORT, HAVE A QUALIFIED ELEC-

TRICIAN OR SERVICEMAN INSTALL AN OUTLET NEAR THE APPLIANCE.

Electrical Requirements

This appliance must be grounded. The drawer

microwave is equipped with a cord having a grounding

wire with a grounding plug. It must be plugged into a

wall receptacle that is properly installed and grounded in

accordance with the National Electrical Code and local

codes and ordinances. In the event of an electrical short

circuit, grounding reduces risk of electric shock by pro-

viding an escape wire for the electric current.

• 120 volt 60Hz, AC only, 15 amp protected electrical

supply.

• Separate the electrical circuit serving only this appli-

ance.

• A properly grounded 3-prong receptacle

(See Figure 2-1).

Clearances and Dimensions

Dimensions shown on this page must be used. Given

dimensions provide minimum clearance. Locate electri-

cal outlet in the shaded area in the upper left hand cor-

ner of the cutout (See Figures 2-2, 2-3, 2-4 & 2-5).

NOTES:

• The drawer microwave can also be installed using

an electrical outlet in an adjacent cabinet within the

area where the provided electrical cord can reach.

Power cord access hole in cabinet should be a mini-

mum of 11/2”(38mm) diameter hole and de-burred

of all sharp edges.

• Always allow sufficient power cord length to the

electrical outlet to prevent tension.

Contact surface must be solid and level. Pay special

attention to the floor on which the drawer microwave will

sit. The floor of the opening should be constructed of

plywood strong enough to support the weight of the

oven, about 100 pounds (45 kg).

Check location where the drawer microwave will be

installed for proper electrical supply.

Your oven can be built into a cabinet or wall by itself or

under a gas or electric wall oven.

Be sure that the clearance of the floor between the wall

oven and the drawer microwave is a minimum of 2”

(51mm).

The microwave interior will easily accommodate a 9”

(229mm) x 13” (330mm) oblong dish or a bag of

microwave popcorn.

SENSOR COOKING

Wolf’s sensor is a semi-conductor device that detects the vapor (moisture and humidity) emitted from the food as it

heats. The sensor adjusts the cooking times and power levels for various foods and quantities.

USING SENSOR SETTINGS:

• After the drawer microwave is plugged in, wait two (2) minutes before using any SENSOR setting.

• Be sure the exterior of the cooking container and the interior of the drawer microwave are dry. Wipe off any

moisture with a dry cloth or paper towel.

• The sensor works with foods at normal storage temperature. For example, popcorn would be at room temp.

• Any SENSOR selection can be programmed with More or Less Time Adjustment (See page 3-8).

• More or less food than the quantity listed in the Sensor Cooking Guide should be cooked following the guidelines

in any microwave cookbook.

• During the first part of sensor use, the food name will appear on the display. Do not open the drawer microwave

or touch STOP/CLEAR during this part of the cycle. The measurement of vapor will be interrupted. If this

occurs, an error message will appear. To continue cooking, touch the STOP/CLEAR pad and cook manually.

• When the sensor detects the vapor emitted from the food, the remainder of cooking/reheating time will appear.

The drawer microwave may be opened when the remaining time appears on the display. At this time, you may

stir or season food, as desired.

• If the sensor does not detect vapor properly, for example when popping popcorn, the oven will turnoff, and the

time of day will be displayed. If the sensor does not detect vapor properly when cooking other foods, will

be displayed, and the microwave will turn off.

• Check food temperature after cooking. If additional time is needed, continue to cook manually.

• Each food has a cooking hint. Touch SETUP/HELP pad when the HELP indicator is illuminated in the display.

Covering Foods: Some foods work best when covered. Use the cover recommended in the Sensor Cooking Guide

for these foods. Be careful when removing any covering to allow steam to escape away from you. You may refer to

the hints by touching the SETUP/HELP pad (See Use and Care Manual page 24).

TO SENSOR COOK (See Figure 3-11):

1. Touch SENSOR COOK pad once. will appear in display (See Menu Label

located on the inside upper right-hand corner of the drawer microwave).

2. Select desired food by touching number pad. For example: Touch 5 for baked potatoes.

will appear in the display.

3. Touch START/ADD MINUTE pad.

NOTES:

• To heat or cook other foods or foods above or below the quantity allowed on the Sensor Cooking Guide (See

Use and Care Manual), cook manually.

MANUAL DEFROST

If the food that you wish to defrost is not listed on the Defrost Guide (See Use and Care Manual page 21) or is

above or below the limits in the “Amount” column on the Defrost Guide, you need to defrost manually. You can

defrost any frozen food, either raw or previously cooked, by using POWER LEVEL at 30%. Follow the 3-step proce-

dure for the “To Set Power Level,” on page 3-4. Estimate defrosting time and press POWER LEVEL pad eight times

for 30% power. For either raw or previously cooked then frozen food, the rule of thumb is approximately 4 minutes

per pound (.45kg). For example, defrost 4 minutes for 1 pound (.45kg) of frozen spaghetti sauce.

Always stop the oven periodically to remove or separate portions that are defrosted. If food is not defrosted at the

end of estimated defrosting time, program the oven in 1 minute increments on POWER LEVEL 30% until totally

defrosted.

When using plastic containers from freezer, defrost only long enough to remove from the plastic in order to place in a

microwave safe dish.
