Ensure that the power supply cable does not come into contact with the appliance’s hot parts.
If the power supply cable is damaged, it must be replaced by the manufacturer or their technical support service, or in any case by a person with similar qualifications, to prevent any risk.

The appliance must be connected to an equipotential system the effectiveness of which must be suitably assessed according to applicable regulations. This connection must be set up between appliances through the suitable terminal which is marked with the symbol . The equipotential conductor must have a minimum section of 2.5mm2.

The equipotential terminal is on the back of the appliance (see the attached “Technical Data Sheet”).

Power supply cable connection (replacement)

The appliance is fitted with a power supply cable connected to the internal terminal board; if it needs to be replaced with a longer one or because it is damaged, it can only be done with another cable having the same electrical characteristics (insulation type/number of conductors/size of conductors in mm²).
Remove the back and/or the right side of the appliance to access the power supply terminal board. Loosen the cable retainer located on the rear (at the bottom) of the appliance (see the attached “Technical Data Sheet”). Disconnect the power supply cable from the terminal board and remove it from the relative cable gland. Insert the new power supply cable in the cable gland up to the terminal board. Prepare the conductors for the connection with the terminal board so that the earth conductor is the last to be extracted from its terminal should the cable be accidentally pulled.
The cable connection must be type “Y” and the insulation of the cable sheath must match type H07RN-F.
The correct section of the cable is shown on the diagram of the power supply terminal board, according to the type of connection between appliance and mains (The cable must match the features in the attached “Technical Data Sheet”). When connected, tighten the cable retainer on the back of the appliance and reassemble the left side and/or the back.

Connect the conductor of phase (L) of the cable to the terminals of the terminal board marked with “1”, “2” and “3” (brown conductor) and the neutral (N) conductor to the terminals marked with “4” and “5” (blue conductor); the ground conductor (yellow/green) must be connected to the terminal marked with the symbol (see diagram available by the terminal board).

230V 3PH ~

Connect the phase conductors (L1, L2, L3) of the cable, respectively, to the terminal blocks marked “1” and “2” (brown conductor), “3” and “4” (black conductor), and “5” (gray conductor); the ground conductor (yellow/green) should be connected to the terminal marked with the symbol (see diagram available near the terminal block).

380/400V 3PH +N~

Connect the 3 phase conductors (L1, L2, L3), the neutral conductor (blue) to the terminal marked “N” and the ground conductor (yellow/green) to the terminal marked with the symbol (see diagram also available near the terminal block)

Connection to the water mains (prepared models only)

The appliance must be supplied with drinking water at a maximum temperature of 30°C. The water pressure must be between 100 and 200 kPa (1.0 -2.0 bar). If the mains pressure exceeds 2.0 bar, install a pressure reducer upstream of the appliance. If the value is lower than 1.0 bar use a pump to raise the pressure.

Water inlet for humidification / steam (prepared models only)

The appliance is equipped with a standardised flexible hose (1.5 metres) with threaded ¾” female fittings and relative gaskets (Fig. 1). Old joints must not be re-used.
The appliance must be supplied with softened drinking water with hardness between 0.5°f and 3°f. It is obligatory to use a softener to reduce the formation of limescale inside the cooking chamber. THE MANUFACTURING COMPANY DISCLAIMS ANY LIABILITY FOR DIRECT OR INDIRECT DAMAGE CAUSED TO THE HOOD DUE TO FAILURE TO COMPLY WITH THIS DIRECTIVE.
The connection to the water mains must be set up through the ¾” threaded solenoid valve located on the back (at the bottom) of the appliance (see the attached “Technical Data Sheet”), using the supplied flexible hose, with a mechanical filter and stopcock installed in between (before connecting the filter, drain off a certain amount of water to flush any dirt out of the hose).

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

Water drain (prepared models only)

A drain pipe comes out of the rear of the appliance (see the attached “Technical Data Sheet”) to drain the cooking chamber. This pipe must be connected to piping with 30 mm internal diameter (DN 16) resistant to steam temperatures (90°C-100°C): avoid metal ones.
The piping must be rigid and must not have bottlenecks along the discharge path (it is advisable to use commercial pipes of special plastic material, with an internal “sealing” O-RING, and to limit the use of “elbow” bends).

The piping must also maintain a steady slope (min. 4-5%) along its entire length.
The considered length is that of the drain pipe of the appliance to the discharge point and must not exceed the measurement of 1.5 meters.

It is mandatory to connect the appliance’s drain to the grey water network through an adequate trap, in order to stop steam/odours from coming out of the drain. The connection to the drain water must be set up separately for each appliance; with multiple appliances connected to the same drain pipe, ensure that the pipe is suitably sized to assure regular drainage with no hindrances.

Water drain for tabletop ovens (prepared models only)

The exhaust pipe can be conveyed to an open (grilled) floor drain (Fig.2); otherwise, between the drain pipe of the appliance and the drain point with a “collection cup” (Fig. 3), there must be a height difference of at least 30 cm in order to facilitate regular flow of water. In any case, the “air gap” (distance between the drain pipe from the appliance and the open drain or the “collection vessel” of the drain duct pipe) must be at least 25 mm.
Wall-mounted discharge is also allowed as long as the drain pipe maintains the steady slope of 4-5%.

Steam drain

The appliance is equipped with a special metal pipe (DN30) for the discharge of steam from the cooking chamber.

No other type of pipe can be connected to this pipe, which protrudes from the back of the casing. Failure to comply with this specific prohibition shall relieve the Manufacturer from any liability concerning the potential malfunction of the appliance and poor cooking quality. Increasing the length of the original drain hose may result in the formation of abnormal “condensation” in the cooking chamber.
To prevent steam from escaping from the exhaust pipe, place the appliance under the extractor hood, or connect it to the “TECNOEKA” extractor hood/condensing hood, specific for the appliance model used.

CLEANING

Manual chamber 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 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.

Semi-automatic chamber cleaning

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 the door closed. switch the oven on adjusting the temperature at 100-120°C. Run a cycle with 100% steam (automatic humidifier knob in position “5”) 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 if available). Dry by running a heating cycle adjusting the temperature at 180-200°C for about 10 minutes (repeat the cycle if necessary). When cleaning is completed leave the oven door slightly open.

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.

Cleaning the door gasket

For hygienic and functional reasons it is good practice to clean the door gasket at the end of every day the oven is used. It must be accurately washed with warm soapy water. It must be rinsed and dried with a soft cloth. Any scaling or food residues must be removed with special care, without using sharp metal tools that might irreparably damage the gasket.

Cleaning the door

The door glass inside the cooking chamber can be cleaned using the same type of degreaser used to manually clean the cooking cabinet; otherwise, a normal (non-toxic) glass cleaning product can be used. A common glass cleaner can also be used to clean the glass of the door facing outwards. In any case, you can simply use lukewarm soapy water. After rinsing, dry the glass surface thoroughly with a soft cloth.
In the event that opacities form between the two glass panes of the door, these can be removed as the two panes can be inspected. (only for prepared models)
For a more thorough cleaning of the oven door, it is advisable to proceed as follows:

insert the equipped plugs in the “A” holes on the hinges;

| completely turn the movable hinge part “A”;

Remove the 2 screws “B” of the metal profile “C” and remove it;
Remove by pulling out the internal glass “C”;
Disconnect the connector of the LED bar “E”;

lift the door gently and withdraw it;

| slowly close the door until the mechanical “block”,lift it and remove it;

put back the door in the initial position by operating inversely.

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 “Information for the user” paragraph.
It is worth remembering that the counter supporting the appliance, or the floor surrounding the appliance area, 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.

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) and water supply. 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.

All TECNOEKA appliances are made of recyclable metal materials (stainless steel, galvanised sheet metal, iron, copper, aluminium, etc.) which make up more than 90% of the total weight of the appliance. Before disposing of the appliance, it is recommended to make it unusable by removing the power supply cable and removing the mechanism for closing compartments and/or openings, if any.
The separate waste collection and subsequent treatment, recovery and disposal, are conducive to the production of equipment with recycled materials and reduce the negative effects on the environment and health possibly caused by incorrect waste handling. Illegal disposal of the product by the user entails the application of administrative penalties.

CONVENTIONAL WARRANTY

The Tecnoeka product is designed for food use only and is covered by warranty according to law (art. 1490 and subsequent articles of the Italian Civil Code) for Professional Customers or customers who purchase from the Dealer with a VAT number. The Tecnoeka product is professional and certified according to IEC EN 60335-1 and can only be sold to professional users.

With the exclusion of any additional warranty, the Vendor agrees to repair, at its sole discretion, only those parts of the products that prove to be tainted by an original fault as long as, subject to forfeiture, the customer has reported the fault within 12 months from the date of purchase and reported the defect within 8 days from the date of discovery, in writing, attaching a copy of the invoice, receipt or tax receipt as proof of purchase.

Including the event in which the customer is unable to produce the invoice, receipt or tax receipt as proof of purchase, meaning that the terms outlined above are not complied with, the warrant is expressly forfeited in the following cases:

1. Faults or breakdowns of components caused by transport.
2. Damage deriving from inadequate electrical, hydraulic and gas supply systems compared to that provided in the installation manual, or anomalous operation of these systems.
3. Damage deriving from incorrect product installation, or installation not carried out in accordance with the installation manual and, in particular, damage due to the inadequacy of the flues and drains that the product is connected to.

    Replacement costs of the oven and relative installation expenses are also excluded from the warranty. The warranty does not cover Products purchased as used or from third parties who are not connected to or authorised by Tecnoeka.
    TECNOEKA SRL shall not be held liable for damage, either direct or indirect, caused by a product fault or as the result of the forced suspension of operation. Repairs under warranty do not result in the extension or renewal of coverage.
    Components replaced under warranty are, in turn, covered by a 6-month warranty from the shipping date, certified by the transport document issued by Tecnoeka. No-one is authorised to change the warranty terms and conditions or to issue others, neither verbal nor written.

AVAILABILITY AND SUPPLY OF SPARE PARTS

Tecnoeka srl keeps and ensures the availability of spare parts for a maximum of 24 months from the date of sale of the finished product to the dealer. Availability cannot be guaranteed after said period.

APPLICABLE LAW AND COMPETENT COURT

Supply relationships will be governed by Italian law, with the express exclusion of the private international law standards and the Vienna Convention on Contracts for the International Sale of Goods of 11.4.1980. Any dispute will be settled exclusively by the Court of Padua.

Without prior notice and liability for Tecnoeka Srl, the products presented in the manual may be subject to technical and design changes for the purposes of improvement, without affecting the essential features relating to operation and safety.
