a. GROUNDING INSTRUCTIONS:
For personal safety, this appliance must be properly grounded.
In the event of an electrical short clrcult, grounding reduces the risk of electric shock by provldlng an escape wire
for the electric current. The power cord of this appliance ISequipped wtth a three-prong (groundrng) plug (F/g. 1)
to mlnlmlze the posslblllty of electric shock hazard from this appliance
The plug must be plugged Into an outlet that IS properly installed and grounded.
WARNING
- Improper use of the grounding plug can result tn a risk of electric shock.
Do not, under any circumstances, cut or remove the third ground prong from the power cord plug.

Fig 2
The consumer should have It checked by a quailfled electrIcian or servlceman if the grounding InstructIons are
not completely understood, or if doubt exists as to whether the appliance IS properly grounded Where a stan-
dard two-prong wall receptacle ISencountered, It ISthe personal responslblllty and obligation of the consumer to
have It replaced with a properly grounded three-prong wall receptacle
1 Usage sltuatlons where appliance’s power cord WIII be dlsconnected Infrequently Because of potential safety
hazards under certain condltlons, we strongly recommend against the use of an adapter plug
However, if you ~1111elect to use an adapter, where local codes permit. a TEMPORARY CONNECTION may be
made to a properly grounded two-prong wall receptacle by the use of an UL ltsted adapter which IS available at
most local hardware stores (Fig 2)
The larger slot In [he adapter must be aligned with the larger slot In the wall receptacle to provide polarity In the
connection of the power cord.
CAUTION: Attaclllng the adaprer ground terminal to the wall receptacle cover screw does not ground the appll-
ante unless the cover screw ISmetal, and not Insulated. and the wall receptacle 1sgrounded through the house
wlnng
2 Usage sltuatlons where appliance’s power cord WIII be dlsconnected frequently Do not use an adapter plug
111these sltuatlons because frequent dlsconnectlng of the power cord places undue strain on the adapter and
leads to eventual failure of the adapter ground terminal The customer should have two-prong wall receptacle
replaced with a tllree~prong (grounding) receptacle by a qualified electrlclan before using the appllanc’e.
3 Use 01 extens’on cords If it IS necessary to use an extension cord, use only a 3-wire extension cord that has
a 3~blade grounding plug, and a S~slot receptacle that WI/I accept the plug on the appliance The marked rating
of the extension cord should be equal to or greater than the electrlcal ra!lng of the appliance

b. CIRCUITS:
For safety purposes this oven must be plugged Into a 15 Amp clrcult. no other electrical appliances or lighting
circuits should be on this line A 20 Amp lrne can be used to permit addrtional outlets. If in doubt, consult a
licensed electrIcIan
C.
VOLTAGE WARNING:
The voltage used at the wall receptacle must be the same as speclfled on the oven model and senal numbers
plate located on the rear of the oven Use of a higher voltage IS dangerous and may result In a fire or other
type of accident causing oven damage. Low voltage WIII cause slow cooklng. In case your microwave oven
does not perform normal operation In accordance with AC power source and voltage, remove the power cord
and then Insert it again.
d. PLACEMENT OF THE OVEN:
Your mIcrowave oven can easily be placed In your kitchen, family room or any other room In your home. Place
the oven on a flat surface such as a kitchen counter top or a specially designed microwave oven cart. Do not
place oven above a gas or electric range. Free air flow around the oven is important.
e. DO NOT BLOCK VENTS:
All air vents should be kept clear during cooking If air vents are covered durrng oven operation the oven may
overheat If this happens a sensttlve thermal safety device automatically turns the oven off. The oven will be
Inoperable until it has cooled sufficiently.
