17. Liquids, such as water, coffee, are able to

overheated beyond the boiling point without

appearing to be boiling. Visible bubbling or boiling

when the container is removed from the microwave

oven is not always present. THIS COULD RESULT

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 it.

    iii)      Do not use straight-sided containers

                   with narrow necks.

      iv)        After heating, allow the container stand

                 in the microwave oven for a short time

                   before removing the container.

    v)     Use extreme care when inserting a

18. VENTILATING HOODS

      1)      Clean Ventilating Hoods Frequently-

          Grease should not be allowed to

                 accumulate on hood or filter

       2) .     When flaming floods under the hood,

                 turn the fan on.

INTRODUCTION

This Microwave Oven service Manual is printed in a loose leaf format. Each part is divided into sections relating

to a general group of components and each section is subdivided in various parts describing a particular

component or service procedure.

The subdividing of the subject matter plus the loose leaf form will facilitate the updating of the manual as new or

revised components and service procedures are introduced.

Each page of this service manual will be identified in the lower right hand corner and as new or revised pages are

published it will be easy to keep the manual up to date by following the filing instructions on the cover letter.

This Service Manual is a valuable service tool and care should be taken to keep it up to date by prompt and

proper filling of subsequent pages as they are issued.
