Important Product Information
WA R N IN G
Precautions to be observed before and during
servicing to avoid possible exposure to excessive
microwave energy , or electrical shock disconnect
power to oven.
Do not operate or allow oven to be operated with
door open.
Make the following safety checks on all ovens to be
serviced before activating the magnetron or other
microwave source, and make repairs as necessary:
• Interlock operation
• Proper door closing
• Seal and sealing surfaces (arcing, wear, and other
damage)
• Damage to or loosening of hinges and latches
• Evidence of dropping or abuse
Before turning on microwave power for any service
test or inspection within the microwave generating
compartments, check the magnetron, waveguide or
transmission line, and cavity for proper alignment,
integrity , and connections.
Any defective or misadjusted components in the
interlock, monitor , door seal, and microwave
generation and transmission systems shall be
repaired, replaced or adjusted by procedures
described in this manual before oven is released to
the consumer .
Check microwave leakage to verify compliance with
the federal performance standard should be
performed on each oven prior to release to the
consumer.
WA RNING
To avoid risk of electrical shock, injury, or death, make
sure these grounding instructions are followed.
Grounding Instructions
WA RN IN G
Do not remove grounding prong when installing
grounded appliance in a home or business that does
not have three wire grounding receptacle, under no
condition is grounding prong to be cut off or removed.
It is the personal responsibility of the consumer to
contact a qualified electrician and have properly
grounded three prong wall receptacle installed in
accordance with appropriate electrical codes
Should a two prong adapter plug be required temporarily
it is the personal responsibility of the consumer to have
it replaced with properly grounded three prong
receptacle or the two prong adapter properly grounded
by a qualified electrician in accordance with appropriate
electrical codes.
Servicing of Grounded Products
The standard accepted color coding for grounding wires
is GREEN or GREEN WITH YELLOW STRIPE. These
ground leads are NOT to be used as current carrying
conductors. It is extremely important that the technician
replace any and all grounds prior to completion of the
service call. Under no condition should ground wire be
left off causing a potential hazard to technicians and
consumer.
WIRING
Good service practice is to never route wiring over
terminals and/or sharp edges. This applies to any
wiring without regard to the circuit voltage. Wire
insulation material and thickness is designed and
regulated for electrical spacing purpose only , but
cannot always be relied upon because of possible cuts
and/or abrasions, which can occur during servicing.

Grounding Instructions
NOTE: Do not under any circumstances cut or remove
grounding prong from the plug or bend power
prongs to fit receptacle other than one shown for
your equipment. Such abuse of the plug can
result in electrical shock or overheating.
WA R N IN G
Improper use of grounding plug can result in a risk of
electrical shock or death.
This equipment MUST be grounded. In the event of an
electrical short circuit, grounding reduces risk of electric
shock by providing an escape wire for electric current.
This oven is equipped with a cord having grounding wire
with a grounding plug. Plug must be plugged into an
outlet that is properly installed and grounded. DO NOT
use a two-prong adapter.
Consult a qualified electrician or servicer if grounding
instructions are not completely understood, or if doubt
exists as to whether the equipment is properly grounded.
Do not use an extension cord. If product power cord
is too short, have a qualified electrician install an
appropriate receptacle. This equipment should be
plugged into a separate 60 Hz circuit with the
appropriate electrical rating label. Models ACE208
require a 208 voltage supply and model ACE230
requires a 230/240 voltage supply. When the
combination oven is on a circuit with other equipment, an
increase in cooking times may be required and fuses
can be blown.
Radio Interference
Microwave operation may cause interference to radio,
television, or a similar oven. Reduce or eliminate
interference by doing the following:
• Clean door and sealing surfaces of oven according to
instructions in
Care and Cleaning
• Place radio, television, etc. as far as possible from
