approximately194lb(88Kg).
•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.
•Theovenmustbeinstalledinaleveledandwell-ventilatedarea.

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 byfollowing the instructions listed below.
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 thereceptacle
conforms to the electrical specification in the table below and written
ontheoven'sdataplatelocatedonthebackoftheunit.
2. Connecttheoventothepowersupplyandturn on.
3. Press foraccesstoMenu screen.
4. Press toentertheSettingsscreen.
5. Enter password 456789 and press OK for access to user settings.
Note: The password may be changed (see page 34).
6. Press toaccessthesecond Settingsscreen.
7. Press toentertheVoltagescreen.

5MultiChef XLT TECHNOLOGY
The MultiChef XLT oven uses a combination of heating for high-speed forced
air convection and microwave energy to heat forced food more quickly than
theconventionalmethods.
The figure below illustrates the steps involving the technology:
a) Internalheatingelementstransferthermalenergytothecirculatingair.
b) Theblowermotorcirculatesairathighspeedand envelopsthefood.
c) The circulatingair goesthrough the catalystwhere the greaseladen vapors
arebroken down.
d) Thebottomheaterhelpstheheattransferwithin thechamber.
e) At the same time, Magnetrons generateenergy via microwave that evenly
heatsthefood watermolecules.

6OPERATIONPRINCIPLES
Microwaves are a type of radiant energy. As well as radio waves, visible light
andinfrared,themicrowavesarepartof theelectromagneticspectrum,i.e.,it
is a form of electromagnetic radiation. They are classified as non-ionizing
radiation, because unlike x-rays and Alpha, Beta and Gamma rays, itseffects
are strictly thermal and therefore do not alter the molecular structure of the
itemthatisbeingirradiated.
The basic principle of microwaves is to cook by molecular vibration. They
penetrate the food surface in a depth that ranges from two to seven
centimeters, heating the molecules of water, fat and sugar by making them
vibrate. The heat is transmitted to the interior of the food by thermal
conduction, demystifying the idea that the microwaves cook food from the
inside out.
The Rocket Express works through the association between microwaves and
hot air directed towards the food. The variables in the operation consist of:
a) Operationtime.
b) Chambertemperature.
c) Microwavespower.
d) Airspeed.
Each operation recipe can be programmed with up to six steps and each of
them can have the variables mentioned above.
Temperatures: The preparation times are short and so are the steps. The
temperature variation between steps will not be observed by the unit.
Normally the temperature used is the same temperature as the cook cavity
set point.
