Read the following information to avoid possible exposure to microwave radiation:

The basic design of the Microwave Oven makes it an inherently safe device to both use and service.

However,therearesomeprecautionswhichshouldbefollowedwhenservicingthemicrowavetomaintainthis

electrical shock, fire, or injury to persons including the following.

1. READ all instructions before usingequipment.

2. READ AND FOLLOW the specific

“PRECAUTIONS TO AVOID POSSIBLE

EXPOSURE TO EXCESSIVE MICROWAVE

ENERGY” on this page.

3. This equipment MUST BE GROUNDED. Connect

only to properlyGROUNDED outlet. See

“GROUNDING / EARTHING INSTRUCTIONS”

on page 5.

4. Install or locate this equipment ONLY in

accordance with the installation instructionsin

this manual.

5. Some products such as whole eggs and sealed

containers—for example, closed glass jars—are

able to explode and SHOULD NOT be HEATED

in this oven.

6. Use this equipment ONLY for its intended useas

described in this manual. Do not use corrosive

chemicals or vapors in this equipment. This type

of oven is specifically designed to heat,cook,

or dry food. It is not designed for industrial or

laboratory use.

SAVE THESE INSTRUCTIONS

To avoid personal injury or property damage, observe the following:

1. Do not deep fat fry in oven. Fat couldoverheat

and be hazardous tohandle.

2. Do not cook or reheat eggs in shell or with

an unbroken yolk using microwave energy.

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 escapesevenly.

4. Do not operate equipment without load orfood

in oven cavity.

5. Microwave popcorn should not be poppedin

oven.

6. Do not use regular cooking thermometers in

oven. Most cooking thermometers contain

mercury and may cause an electrical arc,

malfunction, or damage tooven.

7. Do not use metal utensils inoven.

8. Do not use aluminum foil inoven

9. Never use paper, plastic, or other combustible

materials that are not intended forcooking.

10. When cooking with paper, plastic, or other

combustible materials, follow manufacturer’s

recommendations on productuse.

11. Do not use paper towels which contain nylonor

other synthetic fibers. Heated synthetics could

melt and cause paper to ignite.

12. 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 beforeheating.

13. Toavoid pacemaker malfunction, consult

physician or pacemaker manufacturerabout

effects of microwave energy on pacemaker.

14. An authorized servicer MUST inspectequipment

annually. Record all inspections and repairs for

future use.

SAVE THESE INSTRUCTIONS

WARNING

To avoid risk of fire in the oven cavity:

a. DO NOT overcook food. Carefully attend oven

when paper, plastic, or other combustible

materials are placed inside the oven to facilitate

cooking.

b. Remove wire twist-ties from paper or plastic

bags before placing bag inoven.

c. If materials inside the oven ignite, keep oven

door 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 when not in use.

WARNING

Liquids such as water, coffee, or tea are able to

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 theliquid.

ii) Stir the liquid both before and halfway through

heating it.

iii) Do not use straight-sided containers with narrow

necks.

iv) After heating, allow the container to stand in the

microwave oven for a short time before removing

the container.

v) Use extreme care when inserting a spoon or

other utensil into thecontainer.

INSTALLATION

STEP 1 - Unpack Oven

A. Inspect oven for damage such as dents in door or inside ovencavity.

B. Report any dents or breakage to source of purchaseimmediately.

Do not attempt to use oven if damaged.

C. Remove all packing materials from oveninterior.

D. If oven has been stored in extremely cold area, wait a few hours before

connecting power.

STEP 2 - Place Oven on Counter

E. Recommended countertop surface depth is 28in (72 cm).

F. Do not install oven next to or above source of heat, such as a pizza

oven, grill, or deep fat fryer. This could cause oven to operate

improperly and could shorten the life of electrical parts due to

excessive heat and/or grease.

G. Do not block or obstruct oven filters. Allow access for filters to be

cleaned.

H. Install oven on level countertop surface.

I. Outlet should be located so that plug is accessible when oven is in

place. Oven cord length is 60in (152cm)

STEP 3 –Test Oven Operation

J. Ensure cooking plate is installed.

1. Oven cavity must be cool to touch.

2. Place shelf in oven with curve positioned towardthe

the front of the oven. This ensures proper convection air flow.

K. DO NOT cook food directly on floor ofoven.

A. Allow at least 2in (5.1cm) of clearance around top

of oven. Proper air flow around oven cools

electrical components. With restricted air flow,

oven may not operate properly and life of electrical

parts is reduced.

B. Do not remove back panel bumpers. They ensure

proper clearance.

C. Allow at least 1in (2.54cm) of clearance around

sides of oven.

D. Install oven so oven bottom is at least 3 feet

(91.5cm) above the floor.
