Do not aempt to operate this oven with the door open since open-door
operaon can result in harmful exposure to microwave energy. It is important
not to defeat or tamper with the safety interlocks.
Do not place any object between the oven front face and the door or allow soil
or cleaner residue to accumulate on sealing surfaces.
Do not operate the oven if it is damaged. It is parcularly important that the
oven door close properly and that there is no damage to the:
a) Door (bent),
b) Hinges and latches (broken or loosened),
c) Door seals and sealing surfaces,
The oven should not be adjusted or repaired by anyone except properly
qualified service personnel.

INSTALLATION AND OPERATION MANUAL

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 greade-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.

4 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:

5 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.

INSTALLATION AND OPERATION MANUAL

Microwaves: The microwave is adjustable between 0% and 100% for each 30
second fracon. For example, the microwaves in a one-minute recipe with
microwave programmed at 50% will run for 15 and stop for 15 seconds. Then
they will energize for another 15 seconds and stop for the remaining 15
seconds. In 1 minute, they will act for a total of 30 seconds. The microwaves
heat the food internally and do not require a specific mean to propagate.
Microwaves are reflected by metals but will penetrate glass, plascs, and
ceramics. The microwaves penetrate food and become aracted to sugar, fat
and water molecules.
The use of plasc or paper containers is forbidden because they will burn
inside the oven because of the heat.
Operaon Time: The food heated by microwaves occur from the outside in
and the penetraon level will vary depending on the type of food. Therefore,
you should relate the preparaon me to the food composion, the quanty
of food processed, as well as its density and thickness. The larger the food
amount (quanty or density), the greater the me or percentage will be
needed for the microwave to take effect.
Hot Air Speed: The hot air can be adjusted between 10% and 100% speed.
The hot air is controlled by a blower motor which will envelope the food.
The higher the air speed, the more likely it will be to burn the product on
the outside.
The higher the air speed, the more it will affect the texture and crispness of
the product.

6 RECIPES CREATION
When creang a recipe, all the variables menoned earlier should be
considered. The microwaves and the air speed are the crical factors for a
successful preparaon.
To get faster results in the recipe creaon, we suggest beginning
programming at 1/10 of the total me of preparaon used in a convenonal
process.
The effect of microwaves is more efficient at the beginning of the processes.
For frozen products, create a recipe with two or three steps so the food will
thaw at the beginning and the desired crispness and product presentaon are
achieved toward the end of the process.
Later, combine the air speed variaons to reach the desired crispness and
color. Remember, the air also transmits heat to the food so keep that in mind
when seng blower percentage. The food's weight, size, and shape are
crical when seng the total cook me.
The following informaon is crical when creang a new recipe.
The inial temperature of the product will change the desired results if not
considered (e.g.; frozen, cold, or room temperature).
The size and/or weight variaon of the poron of product will also play a
crucial role in determining the correct sengs.
Only use containers approved for a microwave oven to prevent any
damage and that the product gets properly cooked.
