2. General instruction (for installation technician)

The installation technician must make sure that start-up conforms to current national regulations. The appliance must be installed only by qualified personnel authorised by the manufacturer. She must observe the safety regulations in force in the country where the appliance is installed. All extraordinary maintenance jobs (possible adaptation to another type of gas or replacement of parts) must be performed by qualified personnel having the necessary professional qualifications. The protected devices and / or sealed by the manufacturer and that are not intended for maintenance, adjustment, or adaptation to change of gas must not be handled either by the installer or user. The seals that must be removed to change the gas must be restored at the end of the adaptation. The manufacturer will not respond for damage to people, animals and property due to installation errors. Likewise the manufacturer is not responsible for breakage caused to the appliance by incorrect installation.

2.1 Storage If the appliance has been stored in a warehouse at a temperature below 0°C (min. allowed is – 5°C), it should be brought to a temperature of at least +10°C before it is turned on.

2.2 Transporting the oven During transport, the appliance must be left in its original wooden cage to protect it against damage.

2.3 Unpacking the oven Remove all the packaging before installation, which is formed of a wooden pallet that holds the appliance and cardboard casing to protect it. Check that the appliance has not been damaged during transport and if any damage is discovered immediately inform your retailer and/or the haulier.

page. 6 __________________________________________________________________________________________

Convection gas oven rev. 0___________________________________ MODD. EKF 1111G E UD – EKF 1064G E UD

2.4 Removing the protective film Before using the appliance, carefully remove the special protective film over the stainless steel parts, without leaving any glue residue on the surfaces. If necessary, remove the residue at once with a suitable non-inflammable solvent (e.g. acetone).

2.5 Disposing of the packaging The packaging must be disposed of in accordance with current legislation in force in the place where the appliance is installed. The various types of materials (wood – paper – cardboard – nylon – metal staples) used for the packaging must be separated and delivered to the specific waste disposal centres. In all circumstances the environmental protection regulations must be strictly adhered to.

2.6 Positioning Check the place where the appliance will be installed to ensure that the passages (doors and corridors) are wide enough (the appliance measurements are given in Fig. 3). The appliance must be installed in a well ventilated room with permanent ventilation openings – if possible, it should be placed under an exhaustion hood ensuring complete evacuation of burned gasses produced during baking. Locate the oven on a table or similar support. We advise to use the support given by the manufacturer; otherwise you must consider the weight of the oven. Never on the floor. The maximum working height, referred to the highest surface level, must be 1.6 meters from the floor. After installing the appliance apply the suitable adhesive symbol at a height of 1.6 meters. For easier access and to allow the air to circulate freely around the appliance, leave at least 50 cm between the left side and the wall (or other appliances), and at least 10 cm between the back and the wall and the right side and the wall (see Fig. 3). The natural ventilation that is needed to ensure efficient working for the oven is through the openings on the walls of the outer covering (left side and back). Consequently, it is strictly forbidden to obstruct these aeration openings, even partially and even for short periods.

Failure to observe this specific prohibition, shall release the manufacturer from all liability for the appliance and shall immediately cancel any guarantee rights for the said appliance,

because its constructive conformity has been voluntarily compromised. For the same reason, do not position equipment with a source of heat on the left hand side of the oven; in fact if ambient temperature on that side becomes too high, the oven switches itself off for safety reasons If the appliance is installed near walls, tops, shelves or other similar items, they must not be inflammable or sensitive to heat, otherwise they must be protected by a suitable fireproof covering. In all cases, all fire prevention standards must be strictly adhered to. With regards to the methods of discharging combustion fumes and in compliance with the provisions of the local legislation for the installation of gas equipment, this oven can be classified and therefore installed as follows: Type A1 Installation: drawing the comburent air and discharging flue gases directly into the installation room. This installation requires the working environment to be kept wholesome by emptying the foul air and drawing fresh air through wall fans or extraction equipment.

Type B

Installation: installation required under extraction equipment.

Installation: discharging the flue gases out of the installation room with a draught-

diverter compatible with a vertical tube (diam. 150 mm) making the discharge of the flue gases into the extraction unit or directly into the building flue easy. Since flue gases can reach high temperatures, pay particular attention not to overheat any temperature sensitive elements (extraction equipment filters, electrical cables, etc.). For the details regarding the installation (for instance minimum sections of ventilation, storing of the gas canisters, etc.) see the applicable regulations in force in the country of destination. Pay particular attention so that the volume of air required for the combustion is not obstructed in any way by objects placed under or around the unit.

_________________________________________________________________________________________ page. 7

TECNOEKA Srl _____________________________________________________________ use and instruction manual

The type of installation of ovens (A1, B11 or B21) is subject to national rules; for that reason, the technician in charge must comply with national regulations and then classify the oven by placing a cross on the box on the data plate (A1-B11-B21). The classification on the method of the flues depends on the thermal capacity of the device, on its type, the volume of the room and the type of ventilation present (forced or natural); typically the sections of inflow air and exhaust fumes / vapor depend, among other things, by the total thermal load of equipment present in the room (technical area). Tecnoeka ovens are equipped with a device to let the fumes out fixed on the roof (see Fig. 3); it acts as a draft diverter / windproof in case of installation B11 provided with direct connection to the flue by means of a vertical pipe; However,

the device is an integral part of the oven, and

should never be removed, regardless of the type of installation.

2.7 Gas connection Before installing, make sure that the oven is designed for use with the available gas. If it is not, consult paragraph “Adaptation to other gas” or contact the manufacturer’s technical assistance service. Connection to the gas mains must be made according to the current national norm and subsequent amendments. The oven gas connection is R 1/2; this entry section must not be reduced. Connection to the gas supply line must be made by using rigid or flexible pipes (maximum length 1,5m) , exclusively in metal, with diameters in proportion to the power of the appliance and the length of the pipe route. Make sure that the pipe does not pass close to the hot areas and that it is not subjected to torsion and traction stresses. Install a rapid ON/OFF tap between

_________________________________________________________________________________________ page. 9

TECNOEKA Srl _____________________________________________________________ use and instruction manual

the gas mains and each appliance, in a position facilitating tap opening and shutting operations. After installing the appliance, run a tightness test on the entire gas circuit, using a leak-detector spray or other non-corrosive foam generating substances (do not use flames for this operation). The unions of the copper pipes must be made by using mechanical couplings without seals.

2.8 Electrical connection Connection to the electrical mains must be made according to the current legal regulations. Before making the electrical connection, make sure that the voltage and frequency shown on the rating-plate match those of the electrical supply system and that the latter is provided with an efficient earth connection. The power cable used must not have lower characteristics than: rubber insulated type H07RN-F with diameter of 3 x 1,5 mm2. If connection to the electrical mains is permanent, a multi-core protective switch of adequate capacity must be installed, with contact opening distance of the overvoltage category III (4000 V). The yellow/green earth wire must not be disconnected by the switch. 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. The appliance must be part of an equipotential system - this connection is obtained with the

stop screw marked with the symbol located at the rear. The diameter of the equipotential wire must be 2,5 mm2. When the appliance is operating, the supplied voltage must not deviate from the nominal voltage value of ± 10%. To replace the cable, cut off electrical power, and access the terminal board by removing the oven rear panel. Locate the cables so that the earth conductor is the last to detach from its terminal in the event of reverse pulling. Use an electrical cable with characteristics not below to those mentioned above. If the power supply cable is damaged it must be replaced by another one with the same characteristics (paragraph 1.3), by the manufacturer or their technical support service, or in any case by a person with similar qualifications, to prevent any risk.

2.9 Connection to water mains The oven must be supplied with softened drinking water (see the respective signal next to the connection solenoid-valve), with a hardness value of 0,5 to 5°F (it is mandatory using a water softener to reduce the formation of scaling inside the boiler). The water pressure must be in the range of 100 to 200 kPa (1,0 – 2,0 bar). If the water pressure exceeds 2,0 bar, install a pressure reducer device upstream. If the pressure is below 1,0 bar, use a pressure pump to increase the level.

The connection to the water supply is done using the ¾” threaded solenoid valve on the back (at the bottom) of the appliance (see fig. 3), fitting a mechanical filter with a cut-off cock (before connecting the filter, allow a certain amount of water to flow out in order to remove any waste from the pipe).

Warning Any damage caused by limescale or other chemicals contained in the water are not covered by warranty.

2.10 Connection Water outlet A drain pipe comes out of the rear of the appliance (see Fig.1) to drain the cooking chamber. This pipe must be connected to piping with 30 mm inner diameter (DN 30) resistant to steam temperature (90°C-100°C). To avoid choking the pipe should be stiff and there should be no "elbows" along the drain path. The pipe must also maintain constant slope (min. 5%) along its entire length (the length considered is that of the appliance's drain pipe at the drain point and must not exceed 2 metres). The drain piping must be conveyed into an open floor drain (Fig.2); otherwise, there must be at least 30 cm height difference between the drain pipe of the appliance and the drain point in order to assure regular water drainage.

page. 10 __________________________________________________________________________________________

Convection gas oven rev. 0___________________________________ MODD. EKF 1111G E UD – EKF 1064G E UD

Furthermore, the minimum "air gap" must be 25 mm (distance between the drain pipe from the appliance and the cup of the drain duct pipe). In any case, for reasons of compliance with health regulations in force, the piping connected to the drain pipe of the appliance must not be in direct contact with the drain point. It is recommended to connect the appliance's drain to the grey water network through an adequate syphon, in order to stop steam from coming out of the drain. The connection to drain water must be done separately for each appliance; in case of several appliances connected to the same drain pipe, ensure the pipe is suitably sized to assure regular drainage with no hindrances.

FIG. 4 FIG. 5

2.11 Thermal breaker safety devices The appliance is equipped with a manually reset safety thermostat, to protect against excessive and hazardous overheating which might accidentally occur inside it. In the event of tripping the device interrupts power supply to the appliance and the incoming gas to the burner.

2.12 Disposing of the oven The appliance is made using recyclable raw materials and contains no toxic or harmful substances for people or the environment. The appliance, and its packaging, must be disposed of in conformity with the current regulations in force in the place of installation. The various materials used for its construction must be separated and delivered to the specialised waste disposal centres. In all cases the environment protection regulations must be strictly adhered to.

3. START-UP (for installation technician)

3.1 Check of nominal thermal capacity The nominal thermal capacity must be verified by an authorised technician or by the gas supply Body, observing the information in this use manual. This check must be performed for new installations, adaptation to another type of gas and during all extraordinary maintenance jobs. There is no other possibility of adjusting the nominal thermal capacity – this is done by measuring correct connection pressure and checking if the injector being used is of appropriate diameter. The nominal thermal capacity is controlled by using a gas meter and a chronometer. The exact volume of gas that must flow through per time unit can be obtained from the technical specifications table. This value must be maintained in the specified range, the

permissible tolerance being ±5%.

3.2 Check of connection pressure (Fig. 6) The connection pressure is measured, with the unit working, using a pressure gauge for liquids (for instance a liquid-level gauge with a minimum resolution of 0,1 mbar). To carry out this test, remove the back of the unit and connect the “T” hose of the “M” gauge to the “P” inlet pressure tapping point of the gas solenoid valve, after unscrewing the tapping point screw.

After you have measured the connection pressure, disconnect the hose “T” and screw the tightness screw of the pressure take-off “P”.

3.3 Adjustment to Other Gas To adapt the oven to a type of gas that differs from the one tested in the factory (see technical data plate), replace the injector of the main burner and adjust primary air inflow with the adjustment bush. For this, disconnect the power and, after removing the lateral left panel, access the burner and the primary air adjuster. If you do not have the necessary spare parts, contact the manufacturer’s technical assistance service. Adaptation must be effected by qualified personnel. Consult the technical specifications in table 1 and 3, and then replace the main injector and adjust primary air.

3.4 Injector replacement and adjustment of primary air (Fig. 7) WARNINGS!

“Preheating” function

To activate this function press the key . Activation is confirmed by the green LED coming on The function is automatically disabled when the “preheating” temperature

is reached; otherwise, it may be disabled by pressing the key even during an operative step (oven “preheating” may be interrupted at any time). The function activated in a programmed cooking cycle is not stored with the other program parameters, that is why it must be activated in real time, every time a new cooking cycle starts: either programmed or in “manual” mode.

The function adds a temperature ∆ (delta) (+30°C) always and only to the temperature value

already set in the first step of the cooking cycle

, in order to offset the heat loss due to opening the oven door when the food to be cooked is loaded. If the step is activated, when the cooking cycle starts the time display reads “HEAt”. As soon as the set "preheating" is reached, a “beep” goes off, which is only interrupted when the oven door is opened to load the food (“HEAt” continues flashing). When the door is subsequently closed, the programmed cooking cycle is automatically started, and the time display shows again the set cooking time.

pressing the key . The temperature inside the food to be cooked (core) may be set, using the suitable needleshaped thermal probe (core probe) supplied. The probe must be inserted inside the food, in the thickest area, avoiding contact with any bones. After placing the food in the cooking chamber, extract the cable of the thermal probe and close the oven door. The plug of the probe must be connected into the suitable socket located at the bottom of the control panel. When starting a cooking cycle where the core probe has been enabled in one of the steps (the time display reads: “Prob”), when the set temperature is reached in the food, the cooking cycle moves to the next step regardless of the set time. If however, the core probe is enabled in any of the four steps, leaving the other three disabled, the cooking cycle ends automatically when the temperature set inside the food is reached, regardless of the set time. Since the needle-shaped thermal probe is an extractable accessory or liable to be broken, it is a good rule to set the cooking time also in the step using it. If the probe is connected and working, the step ends when the set temperature is reached; otherwise (probe not connected or broken), the step uses the set time. In any case failed connection (or breakage) of the probe is signalled upon starting the cooking cycle: an acoustic alarm goes off (intermittent “beep”) for 10 seconds, “Prob” starts flashing on the time display, while the value previously set ( - - - ) disappears from the temperature display. The "core" temperature of the food may even just be detected (no value set): it is sufficient for the needle-shaped thermal probe to be inserted in the food.

In this case (with cooking cycle started), by pressing the key the temperature detected by the probe is automatically selected (visible on the temperature display) (LED on ).

Warnings

Before removing the food from the oven after cooking with the needle shaped thermal probe (core probe), carefully extract the still hot probe from the hot food, paying attention not to let it hang outside the cooking chamber: it may cause burns. Before any immediate reuse it is recommended to cool it (thus also preventing harmfully piercing the food). damage the needle shaped thermal probe (core probe), avoid using it in high temperature cooking (OVER 230°C); also avoid letting the probe cable come into contact with the hot metal surfaces inside the cooking chamber.

This function makes it possible to maintain constant, throughout the cooking step, the

difference (∆T) between the temperature inside the food (temperature detected by the needle-

shaped thermal probe) and the temperature inside the cooking chamber. This means that the value of the temperature in the cooking chamber becomes the sum of the temperature inside

the food and a fixed temperature value “∆T” set by the user (see graph).

∆

Cooking time (min.)

The Delta-T temperature is obtained from the difference between the values of the temperature inside the food and the temperature in cooking chamber

In practical terms, there is a slow increase of the temperature in cooking chamber, with a constant difference with respect to the internal food temperature which, exactly because of that, undergoes a prolonged and delicate cooking process (in the case of meat, proteins are protected since surface tensions caused by excessively quick crust formation are avoided). After selecting the cooking temperature for the inside of the food (“core” temperature) and

setting the value (knob “2”), press key again, in order to select function “∆T” (the

∆T

LED switches on) and be able to set (knob “2”) the desired temperature value (experience suggests this value should be between 30°C and 70°C).

Also for cooking with function “∆T”, the method to use the needle-shaped thermal probe is as

described in paragraph “cooking with “core temperature” function.

Please note

pressing the key .If the cooking cycle is controlled by the core probe and has been divided into one or more steps (even timed), when the temperature set with the probe is reached it moves to the next step; if on the other hand one step only has been opted for (even timed), or an “inF” time, the cycle ends and the oven switches off automatically, regardless of the time set for the step.

8 Door device

The device interrupts oven operation (interrupting the cooking cycle) every time the door is opened; when the door is closed the cooking cycle resumes from where it was interrupted.

9 Black-out

When power supply is restored after a black-out, the oven starts working again by pressing key

(the set cooking cycle parameters remain stored).

10 Communicating with the PC

In the lower portion of the control panel (side view) there is a serial port for interactive PC communication. (Remove the suitable protection to access the serial port). By connecting a PC with the “wineka software” (optional) to this port, it is possible to transmit to the oven's “memory” up to 99 cooking programs (recipes) already pre-set (customised) in all operative parameters; conversely, it is possible to acquire from the oven's “memory” the existing cooking programs (recipes) already activated.

11. Cleaning

11.1 General cleaning Before performing any cleaning on the appliance, disconnect the power supply (act on the safety magnetic circuit breaker) and water supply (close the water cock). Let it cool completely. The appliance must be cleaned at regular intervals, even daily, to assure best functionality and lengthening its life cycle. The appliance also has electrical components inside, for safety reasons with water or steam jets especially if aimed at the vents on the metal surfaces of its outer casing (possible hazardous seepage detrimental to electrical components). In the event specific detergents (degreasers) are used for cleaning stainless steel, ensure they do not contain corrosive acid substances (no presence of chlorine even if diluted) or abrasive substances. Carefully follow the instructions and warnings of the detergent's manufacturer and take precautions such as using adequate rubber gloves. Strictly avoid using scouring pads, steel wool and scrapers that may ruin the treated surfaces. Also avoid prolonged permanence on the steel surfaces of foods containing acidic substances (lemon juice, vinegar, salt, etc.) which cause corrosive deterioration.

11.2 Cleaning the cooking chamber Manual cleaning For hygienic reasons it is good practice to clean the cooking chamber on a daily basis, at the end of every day the oven is used. Correct cleaning also prevents the formation of corrosive phenomena inside the chamber, as well as preventing the danger of accidental combustion due to any grease and food residues accumulated over time. To aid cleaning remove the side grilles. The cleaning detergents must not contain abrasive substances or substances of acid/corrosive nature. In case of lack of appropriate detergents it is sufficient to clean the cooking chamber with a sponge soaked in warm soapy water or warm water and a little vinegar.. Rinse with plenty of water (use the suitable shower head if available) and dry well with a soft cloth. The side grilles must be cleaned separately and fitted back on. When cleaning is completed leave the oven door slightly open.

it is forbidden to wash it

page. 22 __________________________________________________________________________________________

Convection gas oven rev. 0___________________________________ MODD. EKF 1111G E UD – EKF 1064G E UD

Semi-automatic cleaning

(ovens fitted with automatic humidification/steam generator)

- spray specific degreaser for stainless steel on the internal walls of the cooking chamber,

on the side grilles, on the fan covers (do not spray onto the fans through the grille) and on the internal door glass;

- let the product act for about 20 minutes with closed door;

- switch the oven on adjusting the temperature at 70-80°C;

- run a cycle with maximum steam (100%) for about 15 minutes;

- upon completing the cycle switch off the oven, let the cooking chamber cool and rinse it

with plenty of water (use the suitable shower head if available)

- dry by running a heating cycle adjusting the temperature at 150-160°C for about 10

minutes (repeat the cycle if necessary).

When cleaning is completed leave the oven door slightly open.

Automatic cleaning (set-up ovens) If already installed, the “KWT” washing system allows the oven's cooking chamber to be automatically cleaned. The “KWT” washing system offers the following programs:

1. L1 – Short washing

2. L2 – Medium washing

3. L3 – Long washing

4. P – Pre-loading detergent and rinse aid from the peristaltic pumps

5. R – Rinse and dry the cooking chamber without using any chemicals. The (optional) “KWT” kit is ready to be installed also at a later stage in oven models supporting it. Important

It is recommended to use the program “P” when first using the “KWT” washing system. In this way the air inside peristaltic pumps and detergent and rinse aid tubes is removed, thus assuring correct functionality of the system.

When cleaning is completed leave the oven door slightly open.

Warnings

Do not open the door during washing operations, as chemical substances used for cleaning and hot fumes might escape.

Danger of corrosion and burns! When the cooking chamber temperature exceeds 100°C (time display reads “Hot”) washing cannot be activated. Before starting a cooking cycle ensure there are no detergent residues in the chamber that has just been washed. Any residues must be removed with a moist cloth suitably protecting your hands, eyes and mouth, and the cooking chamber must be thoroughly rinsed.

11.3 Cleaning the door seal For hygiene and good operations, it is good practice to clean the door seal at the end of each day’s work. It should be carefully washed with warm soapy water, rinsed and dried with a soft cloth. Any incrustations or food deposits must be carefully removed, without using sharp metal tools which could irreparably damage the seal.

11.4 Cleaning the door The glass on the door inside the cooking chamber can be cleaned with the same degreaser as used for cleaning the chamber or a normal glass cleaning product can be used (non toxic). Normal glass cleaning products can also be used to clean the glass on the outside of the door, or simply warm soapy water, rinse and then dry the glass well with a soft cloth. If dull marks form between the two door glasses, these can be removed by opening the internal glass. To do this, with open door, move the " grip " available on the right side of the top ( metal ) section that holds the internal glass, and pull up to release the glass from its " clips" seats. After clearing the dirt between the two glasses , close the internal glass pushing the outer glass until it hooks back to its " clips" seats.

_________________________________________________________________________________________ page. 23

TECNOEKA Srl _____________________________________________________________ use and instruction manual

11.5 Cleaning the external casing The outer steel surfaces must be cleaned with a cloth soaked in warm soapy water or mixed with a little vinegar, they must be rinsed well and dried with a soft cloth. Should you wish to use specific products on the market, these must comply with the cleaning requirements set out in the “General information” paragraph”. It is worth remembering that the counter supporting the appliance or the floor surrounding the area where the appliance is should also be cleaned without using acid corrosive substances (e.g. muriatic acid) since the vapours released by them might corrode and deteriorate the outer steel shell and cause irreparable damage to the electrical components inside the appliance.

11.6 Inactivity period Should the appliance not be used for a long extent of time, it is good practice to disconnect it from the power supply (act on the safety magnetic circuit breaker located upstream of the appliance), the gas supply (close the stopcock on the mains) and water supply (close the stopcock on the mains). It is recommended to clean it with care internally (cooking chamber) and externally, paying special attention to removing any salt residues which might lead to corrosion on the steel surfaces. It is also recommended to protect the appliance with oil-based spray products (e.g. Vaseline oil) which form an effective protective film when sprayed on the surfaces. Leave the door of the cooking chamber ajar. Adequately covering the appliance, finally, allows it to be protected from dust.

12. Maintenance

12.1 General information A periodic check (at least once a year) of the appliance contributes to extending its life and assures proper functionality. Any maintenance operation on the appliance must only be done by highly qualified personnel trained in the operations to be performed. Before performing any maintenance on the appliance, the power supply must be disconnected (act on the safety magnetic circuit breaker located upstream of the appliance) and let it cool down. The components that might require maintenance are accessible by removing the left side and/or back of the appliance.

12.2 Lamp on door Electrically disconnect the appliance. The lamp is housed between the two door glass panes. Just open the inside glass pane to replace it. Replace the lamp with one having the same functional features. The lamp is of the halogen type: it must not be touched with bare hands. Close the internal glass again and connect to the power supply.

12.3 Door gasket replacement The door gasket has a rigid profile with retainer fins. This profile must be inserted in the suitable guide on the front of the cooking chamber. To replace the gasket just remove the worn one from the guide (pull harder at the 4 corners). Clean the guide from any dirt and insert the new gasket (it is advisable to moisten the gasket profile with soapy water to make fitting easier).

12.4 Cleaning the fans The fans must be regularly cleaned with appropriate descaling products. All their parts must be thoroughly cleaned, eliminating any limescale. The fan cover must be removed to access fans. When cleaning is completed fit the cover back on operating in reverse order.

Important

During the assembly of the fan-cover, pay attention to re-position properly, on its locations, the 2 pipes that introduce water to fans; in a different way, the pipes interfere with fans themselves during the functioning, causing damages to the appliance, of which The Manufacturer cannot be held responsible

12.5 Resetting the thermal breaker safety device This device is accessed by removing the left side and/or back of the appliance. The device is reset by pressing hard the relevant button.
