in your new Cadco convection oven. Most
solvents or degreasers will remove any
residue.
4.INSTALLATION
4.1ELECTRICAL CONNECTION
The connection to the electrical power supply
network must be done according to the standards in force.
Before connecting make sure that the voltage
and the frequency correspond to that stated
on the data plate on the oven.
Place a bi-polar switch between the oven
and the network accessible after installation,
whose contacts have a minimum opening
distance of 0.1 inches, with an appropriate
input (for example, magnetothermal switch).
When the oven is in operation, the power
supply voltage must not vary from the value
of the nominal voltage by more than ± 10%.
The oven must be connected to the
ground line of the network.
We do not suggest using the Cadco-Unox
Convection Ovens for built in applications.
Measure to make sure that your new oven
will fit in your available space.

4.3 MAINTENANCE
Before carrying out any type of maintenance
it is necessary to disconnect the electrical
power supply and wait for the oven to cool
down.
OV-600 ONLY
Electrical connection must be a proper outlet
for the 3 pronged cord. Before connecting
power, make sure the voltage and frequency
correspond to the data plate on the oven
(120 volts/60hz.), and that your electrical circuit can handle the12.5 amps used by the
oven in addition to any other appliances
operating on the same circuit.

- Securely replace the black safety cover.
- Begin food preparation after the oven is
preheated.
If the thermal breaker shuts your oven off,
before turning your oven on, be sure to
check your entire circuit to verify that the
total amps being drawn by all the appliances, lights, etc. on that circuit do not
exceed the amps available on that circuit.
All repairs should be performed by a Cadco
authorized service technician using only genuine Cadco-Unox parts.
III. CONVECTION
COOKING
Your Cadco-Unox oven is designed to prepare food, and it should be used for that purpose only.
1. COOKING PRINCIPLES
Accurate times and temperatures assure
perfectly cooked foods. Cooking is an art, not
a science. People will never agree on the
meaning of “done”, or “perfectly cooked”.
Here are some tips that will help ensure success with your convection cooking.
temperatures.
- The oven operates between 175°F and
500°F.
Proper air circulation is necessary for successful convection cooking in all convection
ovens. We suggest you allow a proper clearance of 1-3 inches between pans when cooking for best results.
Never salt foods while they are in the oven.
Salt can damage the interior surfaces of your
oven and affect the efficiency of the electrical
components.
2. COOKING
Convection ovens work by moving the air
inside the cooking chamber to create even
heat throughout the oven. This circulating air
simply removes the [cool] insulating barrier of
air between the cold food and the hot air in
the cooking chamber allowing the food to
cook more quickly. In essence, the moving air
makes heat hotter, as wind chill makes cool
colder.
You will want to rely on an instant read, pocket probe while you are getting used to convection cooking. Your probe will help you
standardize times and temperatures as well
as assuring safe internal food temperatures
have been reached.
- The temperature of the food going into the
oven will affect the cooking time. Frozen
foods take longer to cook than refrigerated
foods.
- Three trays of chicken will take longer to
cook than three pieces of chicken.
- To convert your conventional oven recipes to
convection oven production simply reduce
the cooking temperature by 25F-30F
degrees.
- Most recipes can be converted by having
shorter cooking times and/or reducing your
cooking temperatures.
- We suggest that you use an instant read
probe to help you determine the actual
internal temperature of your foods. This will
help you safely determine correct times and
Preheat your oven to 30F-50F degrees higher than you the temperature you want to cook
at. After you have loaded the product into the
oven and the door is closed turn the temperature back to your intended cooking temperature.
Check cakes and cupcakes with a toothpick
to determine if they are done. If the toothpick
comes out “clean” [no batter on it] when
pushed into the center of the product, it’s
done!
We recommend roasting meats on a cooking
rack, in a shallow sided pan to allow air to
circulate all around the roast.
ENGLISH

Page 10
Salt pulls moisture out of meats. Season your
entire roast but only salt the fat portion.
3. TIMES AND TEMPERA
Products vary greatly. These times and temperatures may need minor modifications to
meet your particular standards. Use your
pocket probe to determine what’s right for
you.
- Rare roast beef – 130F
- Medium roast beef – 140F
- Medium well roast beef – 150F
- Well done roast beef – 160F
- Hamburger – 165F
- Pork – 160F - 170F
- Chicken – 185F done and no “red bone”.
- Fish/Seafood – 160F
TURES
ENGLISH
boneless fresh chicken breasts – 400F for 15
minutes.
- Fish sticks [frozen, browned] – 350F for
15/18 minutes.
- Shrimp [fresh 26-30 ct.] 350F for 10 minutes.
- Salmon fillet [6 oz. fresh] 325F for 12/15 min
utes.
- Potatoes [90 ct. baked] 375F for 45/60 minutes.
- Pizza [frozen 14”] 400F for 18 minutes.
- “Pocket” type sandwiches 350F for 18/20
minutes.
- Mozzarella sticks 350F for 10 minutes.
Here is a handy “Rule of Thumb” for roasting
meats at 325F
- Rare roast beef – 15/20 minutes per pound.
- Medium roast beef – 20/25 minutes per
pound.
- Well done roast beef – 30/35 minutes per
pound.
- Pork – 20/25 minutes per pound.
- Poultry – 20/25 minutes per pound.
- Ham [cured, not fresh] – 12/18 minutes per
pound. [Cured hams are already cooked so
all we have to do is heat them to 140F]
Here are some common products and their
approximate cooking times.
- Cookies 310F-325F for about 10-20 minutes,
depending on recipe and cookie size.
