INSTALLATION AND OPERATION MANUAL
Do not use this product near water such as near the kitchen sink, in a wet
basement, or near a swimming pool.
Do not use a water jet for cleaning. Please see cleaning instrucons for proper
cleaning.
When cleaning the surface of the oven use only non-abrasive products
applied with a nylon sponge or so cloth (page 39).
To reduce the risk of fire in the oven cavity:
Remove wires used to seal paper or plasc bags that will be into the oven.
Carefully monitor equipment when materials such as paper, plasc, and other
combusble materials are placed inside the oven for easy cooking.
Remove all contents located inside the oven cavity.
If the product catches fire inside the cook cavity, close the door immediately
and turn the unit off or unplug it. The power can also be turned off at the
circuit breaker.
Do not use the cavity of the appliance for storage.
Always wear thermal gloves or use holders or tongs to remove the food from
inside the equipment to avoid burns.
Liquids heated in the microwave can a cause delayed erupon due to thermal
shock.
The appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilies, or that have not been
properly trained to operate the unit.
Liquids, such as water, coffee, or tea are able to be 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 IN VERY HOT LIQUIDS SUDDENLY BOILING OVER
WHEN THE CONTAINER IS DISTURBED OR A UTENSIL IS INSERTED INTO THE
LIQUID.
The minimum height of free space above the microwave should be of 5.9in
(150mm).
Only use utensils suitable for use in microwave ovens.
When heang food in microwave safe container, check the oven frequently
due to the possibility of ignion.
The oven should be cleaned daily and any food remains should be removed.
Failure to maintain the oven in a clean condion could lead to deterioraon of
the surface that could adversely affect the life of the appliance and possibly
result in the loss of warranty.

4.3 Electric Power
.
Note: The oven must be properly configured for opmum performance
before using for the first me. Follow the steps listed below to set the oven
operang system to either 208V or 240V supply voltage based on the voltage
being supplied at the oven's receptacle. This configuraon step is only
performed on the inial set-up and installaon. The oven will not need to be
configured again as long as the supply voltage remains unchanged.
The ovens are shipped in a defaulted posion of 240V for safety unless
specified on the original purchase order. Changes to this set voltage can be
easily done by following the instrucons listed below. Please contact Praca
Technical Support for more informaon 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 configuraon of the receptacle
conforms to the electrical specificaon in the table below and wrien
on the oven's data plate located on the back of the unit.
2. Connect the oven to the power supply and turn on.
3. Press for access to Menu screen.
4. Press to enter the Sengs screen.
5. Enter password 456789 and press for access to user sengs.
Note: The password may be changed (see page 34).

Make sure that the electrical characteriscs of building electric network
follow the technical specificaons of the oven which can be found on the
idenficaon plate located on the back panel and in the electrical table
below.
Use a dedicated circuit breaker for the oven. The maximum distance between
the right side of the oven and the electrical receptacle is 6 .
Properly size the circuit breaker and network cables.
The oven MUST be properly grounded. In the event of damage due to
improper grounding to third pares and/or to the equipment, the will be held
responsible and will characterized as negligence due to the non-compliance
with the standards.
There is an equipotenal point on the rear panel of the oven.

5 ROCKET EXPRESS TECHNOLOGY
The Rocket Express oven uses a combinaon of heang for high-speed forced
air convecon and microwave energy to heat forced food more quickly than
the convenonal methods.
The figure below illustrates the steps involving the technology:
Internal heang elements transfer thermal energy to the circulang air.
The blower motor circulates air at high speed and envelops the food.
The circulang air goes through the catalyst where the grease laden vapors
are broken down.
The boom heater helps the heat transfer within the chamber.
At the same me, Magnetrons generate energy via microwave that evenly
heats the food water molecules.

6 OPERATION PRINCIPLES
Microwaves are a type of radiant energy. As well as radio waves, visible light
and infrared, the microwaves are part of the electromagnec spectrum, i.e., it
is a form of electromagnec radiaon. They are classified as non-ionizing
radiaon, because unlike x-rays and Alpha, Beta and Gamma rays, its effects
are strictly thermal and therefore do not alter the molecular structure of the
item that is being irradiated.
The basic principle of microwaves is to cook by molecular vibraon. They
penetrate the food surface in a depth that ranges from two to seven
cenmeters, heang the molecules of water, fat and sugar by making them
vibrate. The heat is transmied to the interior of the food by thermal
conducon, demysfying the idea that the microwaves cook food from the
inside out.
The Rocket Express works through the associaon between microwaves and
hot air directed towards the food. The variables in the operaon consist of:
Each operaon recipe can be programmed with up to six steps and each of
them can have the variables menoned above.
Temperatures: The preparaon mes are short and so are the steps. The
temperature variaon between steps will not be observed by the unit.
Normally the temperature used is the same temperature as the cook cavity
set point.
