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.
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. 2 anti-rollover brackets with relative fastening screws are fitted. The brackets have to be fixed to the appliance through the holes present on the back panel for this purpose. The bases of the brackets must be fixed to the base plane supporting the equipment, using screws suitable to the material of the plane itself.

_________________________________________________________________________________________ page 7
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 - 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).
Connection of power cable - To access the power supply terminal board just remove the side/rear panel of the appliance. Loosen the ring nut of the cable gland at the rear of the appliance and run the cable through it until reaching the terminal board. 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 mm2 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 orange indicator light indicate that the oven is operating and that cooking time is active.
Line indicator light - The green line-indicator light indicates that the oven is electrically connected to the power supply line.
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 Convection cooking + umidifier key - Switch on the oven, turn the adjustment thermostat knob to at least 150°C setting. When this temperature value has stabilised, press the humidification button each time you wish to increase humidity in the cooking chamber..
Defreezing - Activate the oven and turn the thermostat knob to the OFF position.
TECNOEKA Srl ______________________________________________________________ use and instruction manual
page 10 _________________________________________________________________________________________
9. Cooking advice
Traditional cooking - Heat is supplied from above and below and, therefore, it is preferable to use the central guides. If cooking requires extra heat from above and below, use the top or bottom guides.
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 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 - 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. To clean the steel parts, do not use products containing chlorine (sodium hypochlorite, hydrochloric acid, etc) even if diluted. Use specific off­the-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-the­shelf products.

Cleaning flap door (for pre-set ovens) For more comprehensive oven door cleaning it is recommended to proceed as follows:
- open the door completely;
- insert the suitable pins supplied in the holes “A” on the two hinges (Fig. 8);
- slightly lift the door and extract it (Fig. 9); Replace the door in its housing operating in reverse order.
(Fig. 3) (Fig. 4)
Replacing oven lamp - Electrically switch off the appliance; unscrew the protective glass cap; unscrew the screws that secure the glass support and the relative seal (Fig.5) and replace it with another lamp suitable for high temperatures (300°C), with the following characteristics:
- Voltage 230/240 V
- Power 40 W
The lamp is of the halogen type: it must not be touched with bare hands. Reassemble the glass support and its gasket.
