4. Instructions for the installer
The following instructions are aimed at the qualified installer, to ensure that he carries out
the installation, adjustment and maintenance operations as correctly as possible and according
to current legal regulations. Any operation must be performed with electrical power cut to the
appliance.
Before using the appliance, carefully remove the special adhesive film protecting the parts in
stainless steel. Do not leave any glue residues on the surfaces. If necessary, remove them at
once, with an appropriate solvent.
Fitting the feet - The feet are inside the appliance and must be secured on the four threaded
holes on the base. If necessary, the height of the feet can be adjusted by screwing or
unscrewing.
Positioning - Position the appliance perfectly horizontally on a table or similar support (the
table or support must be at least 85 cm above the floor). Position it at a distance of not less
than 10 cm from the side and rear walls, to enable natural ventilating air to circulate freely
around it. The appliance is ventilated through specific openings on the metal walls of the outer
housing , and ensures efficiency and long-life. For this reason it is strictly forbidden to obstruct
these ventilation openings, even partially or for short periods. Failure to observe this specific
prohibition releases the manufacturer of the appliance from all responsibility and immediately
voids any guarantee rights for the said appliance, because its constructive conformity has been
voluntarily compromised. Furthermore, the appliance is not suitable for embedding and for
grouped positioning with other identical appliances.
Electrical connection - The appliance must be connected to the electrical mains according to
current legal regulations. Before making the connection, make sure of the following:
- the voltage and frequency values of the power supply system match the values on the
"technical data" plate affixed on the appliance;
- the limiting valve and the system are able to support the appliance's load (see the
"technical data" plate);
- the power supply system has an adequate earth connection according to current legal
regulations;
- a single-pole switch with minimum between-contacts aperture of 3 mm, sized to the
load and conforming to current legal regulations, is fitted between the appliance and the
mains in the direct connection to the mains;
- the single-pole switch used for connection is easy to reach when the appliance is
installed;
- the yellow/green earth wire is not interrupted by the switch;
- the power supply, when the appliance is operating, must not deviate from the rated
voltage value by ±10%;
- make sure that after inserting the power supply cord into the terminal block it does not
come into contact with any of the cooking range's hot parts.
Connection of power cable - The terminal board is on the rear panel of the appliance. Open
the terminal board cover by obtaining leverage with a screwdriver on the two side fins. Loosen
the cable gripper screw and allow the cable to pass through it. Arrange the conductors so that
the earth conductor is the last to detach from its terminal if the cable goes into a state of faulty
traction. Connect the phase conductor to the terminal marked with the letter "L", the neutral
conductor to the terminal marked with the letter "N" and the earth conductor to the terminal
marked with the symbol
. Tighten the ring-nut of the cable gripper and close the terminal
board cover. The appliance must be connected to an equipotential system whose efficiency
must first be checked according to current legal regulations. This connection must be made
between different appliances by using the appropriate terminal marked with the symbol
. The
equipotential conductor must have a minimum diameter of 10 mm2 The equipotential terminal
is at the rear of the appliance.

Safety thermal breaker - The appliance has a manually reset safety thermal breaker. It
protects against excessive dangerous over-temperatures which could be accidentally generated
inside the appliance. This device is located on the back of the oven
5. Use instructions (for the user)
For first use, we advise you to let the appliance to run load-free at maximum temperature for
about one hour. In this way, any unpleasant smells due to thermal insulation and residual work
grease are eliminated.
This appliance must be used solely for the purpose for which it was expressly designed, i.e.
cooking foods in the oven. Any other use is considered unsuitable.
The appliance can be used: for all oven cooking of deserts, pizzas, meat, fish, vegetables, as
well as for gratinating, and for re-conditioning cooled and frozen foods.
When placing food in the cooking compartment, leave a space of at least 40 mm between
pans in order not to over-obstruct air circulation.
Do not use pans with higher than necessary edges: edges are barriers which prevent the
circulation of hot air.
Warm up the oven before every cooking operation to obtain maximum uniformity.
Do not salt foods in the cooking compartment.
6. Residual risks (for the user)
After a cooking operation, open the door cautiously, to avoid a violent outflow of heat which
could cause burns.
While the oven is in operation, pay attention to the hot zones (marked on the appliance) of
its external surfaces.
Place the machine on a bench or similar support, at a height of at least 85 cm from the floor.
The bench or support must be able to support the weight of the machine and house it
correctly.
The appliance contains electrical parts and must never be washed with a jet of water or
steam.
The appliance is electrically connected: before attempting any cleaning operation, cut power
to the appliance.
Do not use the door handle to move the appliance (the glass panel may break).
When the tilting door is wide open, there is the risk that things could be placed on the
surface with the risk of irreparably damaging the door hinges.

_ Electric Ovens _ rev. 2 _____________________________________________________________ KF 620 – KF 622 _
_________________________________________________________________________________________ page 9 _
9. Cooking advice
Convection cooking - Heat is transferred to the foods by pre-heated air, forced to circulate by
in the cooking chamber. The heat quickly and uniformly reaches all parts of the chamber,
enabling simultaneous cooking of different types of food (providing they have the same cooking
temperature), placed on the shelves without mixing tastes and smells. Convection cooking is
particularly convenient for rapid de-freezing, and for sterilising preserves and drying mushrooms
and fruit.
Cooking desserts - Desserts require a very high temperature (usually from 150 to 200°C) and
a pre-heated oven (about ten minutes). The oven door must not be opened until at least 3/4 of
the cooking time has elapsed. Whipped dough must be difficult to detach from a spoon
because excessive fluidity would prolong cooking time to no avail.
Cooking meat and fish - Meat to be cooked should weight at least 1 Kg to prevent it drying
too much. Very tender red meats to be cooked rare, which must be cooked on the outside to
keep all their gravy, require short cooking time at high temperature (200-250°C). The gravy
ingredients must be placed immediately in the pan only if the cooking temperature is brief,
otherwise they should be added during the last half-hour. You can check the degree of cooking
by squashing the meat with a spoon: if the meat does not yield, it is correctly cooked. For roast
beef and fillet, which must remain pink inside, cooking time must be very brief. Meats may be
placed on a plate suitable for oven cooking or directly on the grill, under which you should
place a tray to collect the gravy. When cooking has finished, we advise you to wait for 15
minutes before cutting the meat so that the gravy does not come out. Before being served, the
dishes may be kept hot in the oven at minimum temperature.
10. Routine cleaning and maintenance
(WARNING: Cut power to the appliance before every operation)
General cleaning - Clean the oven when it is cold. Wash enamelled parts with lukewarm
water and soap, do not use abrasive products, steel wool, or acids, which could ruin them. To
clean the steel parts, do not use products containing chlorine (sodium hypochlorite, hydrochloric
acid, etc) even if diluted. Use specific off-the-shelf products or a little hot vinegar. Rinse
thoroughly with water and dry with a soft cloth. Clean the glass door of the oven with hot
water only, and do not use rough cloths. Do not allow foods (especially acid foods such as salt,
vinegar, lemon, etc) to stagnate on the stainless steel parts, because they could deteriorate. Do
not wash the appliance with direct jets of water, because if water enters, this could limit the
appliance's safety. Do not use corrosive substances (e.g. hydrochloric acid) to clean the oven' s
support bench.
Cleaning the oven
- It is good practice to clean the oven interior at the end of every day of
duty. In this way it will be easier to remove cooking residues, preventing them from burning
when the oven is next used. Clean it accurately with hot water and soap or with the appropriate
off-the-shelf products.
Cleaning the oven door
- To clean the oven door thoroughly, proceed as follows:
- fully open the door;
- attach the rings “A” onto the hinge seats (Fig. 3);
- lift the door gently and withdraw it (Fig. 4).

Replacing oven lamp - Electrically switch off the appliance; unscrew the protective glass cap
(Fig. 5); unscrew the lamp and replace it with another lamp suitable for high temperatures
(300°C), with the following characteristics:
- Voltage 230/240 V
- Power 25 W
- Fitting E 14
Refit the glass cap and power up the appliance.
11. Technical assistance
Before leaving the factory, the appliance was completely regulated and tested by expert
specialised personnel to guarantee the best operating results.
All repairs and settings must be performed with utmost care and attention, respecting
national safety regulations in force. Always contact your retailer or our nearest Service Centre,
giving details of the problem, the appliance model and the serial number (on the rating plate on
the rear panel).
For any maintenance the user can contact Tecnoeka by calling the telephone numbers on the
cover or going to www.tecnoeka.com.
12. Informations to the consumers
Further to Directive 2002/96/EC, the symbol of the crossed rubbish skip on
the appliance means that at the end of its life, the product must be
disposed of separately from the other rubbish. The user must hand the
appliance to a specialised waste collection centre for electric and electronic
equipment.
The separate collection of the rubbish and subsequent treatment, recovery and disposal help to
produce other equipment using recycled materials, reducing the negative effects on the
environment and public health, which would be caused by incorrect management of the
rubbish.
Should the user dispose of the product abusively, administrative sanctions would be applied.
