3 - PRECAUTIONS TO AVOID POSSIBLE EXPOSURE
TO EXCESSIVE MICROWAVE ENERGY
(a ) Do not attempt to operate this oven with the door open since open-door
operation can result in harmful exposure to microwave energy. It is important not
todefeatortamperwiththesafetyinterlocks.
(b ) Do not place any object between the oven front face and the door or allow soil
orcleanerresiduetoaccumulateon sealingsurfaces.
(c ) Do not operate the oven if it is damaged. It is particularly important that the
oven door close properly and that there is no damage to the: (1 ) Door (bent), (2 )
Hingesandlatches(brokenorloosened),(3)Door sealsand sealingsurfaces,
(d ) The oven should not be adjusted or repaired by anyone except properly

approximately174lb(79Kg).
• Donotblocktheairinletsoroutletsof theunit.
• The oven must not be positioned near stoves, deep fryers, hot plates and
other equipment that releases fat, fumes and heat. The ventilation, electrical
panel and motor vents must be far from these heat sources to prevent
damagetotheelectricalsystemoftheappliance.

4.3ElectricPower
Note: The oven must be properly configured for optimum performance
before using for the first time. Follow the steps listed below to set the oven
operating system to either 208V or 240V supply voltage based on the voltage
being supplied at the oven's receptacle. This configuration step is only
performed on the initial set-up and installation. The oven will not need to be
configuredagainaslongasthesupplyvoltageremainsunchanged.
The ovens are shipped in a defaulted position of 240V for safety unless
specified on the original purchase order. Changes to this set voltage can be
easily done by following the instructions listed below. Please contact Pratica
Technical Support for more information if needed +1.214 584.6269.
1. Verify the supply voltage. If this knowledge is not readily available,
please use a qualified technician or individual familiar and comfortable
with electricity to take the measurements. Care must be used to avoid
electrical shock. Confirm the electrical configuration of the receptacle
conforms to the electrical specification in the table below and written
ontheoven'sdataplatelocatedonthebackoftheunit.

5MultiChef XSTECHNOLOGY
The MultiChef XS oven uses a combination of heating for high-speed forced
air convection and microwave energy to heat forced food more quickly than
theconventionalmethods.
Thefigurebelowillustratesthestepsinvolvingthetechnology:
1) Magnetrons generate energy through microwaves, which uniformly heat
thewatermoleculesofthefood;
2) Internalheatingresistorstransferheatenergyto circulatingair;
3) TheStirrerdistributesthemicrowavesevenly;
4) Impingedairis directedtowardfood;
5) Inferiorresistorshelptheheattransferwithinthechamber;
6) The Catalytic Converter converts the volatile organic compounds into
