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). Once you have put the machine, it
should not exceed height of 1.60 meter from 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 omnipolar switch with minimum between-contacts aperture of the overvoltage
category III (4000 V), 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 omnipolar 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.
- if the supply cable is damaged then it must be replaced by the manufacturer or
by your technical support or by a qualified person to avoid any risk.
Connection to the water mains (for ovens predisposed)
- The appliance must be fed with
softened drinking water, with hardness from 0.5°F to 3°F (it is obligatory to use a softener to
reduce the formation of lime inside the cooking chamber) and pressure in the range from 100
to 200 kPa (1.0 - 2.0 bar).
Connection to the water mains should be made through the threaded 3/4" solenoid-valve on
the rear (on the bottom) of the appliance, fitting in between a mechanical filter and an on/off
tap (before you connect the filter, allow a certain quantity of water to flow out in order to drain
any waste from the pipe).
Electric Ovens rev. 0 ________________________________________________ EKF 423 P - EKF 423 UP
_________________________________________________________________________________ page 7
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 2,5 mm
2
The equipotential terminal is at the rear of the appliance.
Safety thermal breaker - The appliance has safety thermal breaker. It protects against
excessive dangerous over-temperatures which could be accidentally generated inside the
appliance. If the device is tripped, it interrupts electrical power to the appliance and thus
prevents it from operating.
5. Use instructions (for the user)
This appliance is not intended for use by persons (including children) with reduced phycal,
sensory or mental capabilities, or lack of experience and knowledge. Unless they have
beengiven supervision or instruction concerning use of appliance by a person responsible for
their safety.
Children should be supervised to ensure that they do not play with the appliance.
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).

Programming cooking time - To run the oven, turn the programmer knob (Fig. 1) in line
with symbol
(continuous operation) or in line with the selected cooking time (up to 120
minutes). In the second case, end of cooking is signalled by the oven switching OFF
automatically.
Programming cooking temperature - Turn the knob of the adjustment thermostat (Fig. 2)
in line with the temperature selected for cooking.
Control thermostat indicator light - The control thermostat orange indicator light goes OFF
whenever the programmed temperature is reached inside the cooking compartment. It lights
up again when the thermostat is tripped to re-establish this temperature.
"End of cooking" programmer indicator light - The programmer green indicator light
indicate that the oven is electrically connected to the power supply line and that cooking time
is active.
Oven internal light - The light is always on when the oven is operating.
8. Oven cooking
For cooking, before putting food in, warm up the oven to the required temperature. When the
oven reaches the temperature, put the food in and check cooking time. Switch off the oven 5
minutes before the theoretical time in order to recover stored heat.
Convection cooking - Activate the oven and turn the thermostat knob in line with the
required temperature.
Defreezing - Activate the oven and turn the thermostat knob to the OFF position.
Humidifier key (for ovens predisposed ) - To produce vapour inside the oven while the oven
is operating and the chamber is hot, press the key (commanding the humidifier) for a few
seconds.
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
Electric Ovens rev. 0 ________________________________________________ EKF 423 P - EKF 423 UP
_________________________________________________________________________________ page 9
cooking temperature), placed on the shelves without mixing tastes and smells. Convection
cooking is particularly convenient for rapid defreezing, 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 - 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;
- insert the equipped plugs in the “A” holes on the hinges (Fig. 3);
- lift the door gently and withdraw it (Fig. 4);
- put back the door in the initial position by operating inverserly.

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.
