that may comprise the packaging are potentially dangerous and must be kept out of reach of children and
animals; they must be duly separated and delivered to the respective collection centres (recycling centres).
In any case please adhere to the local environmental protection regulations.
3.6 Placement
Check the place of installation making sure that the transit areas (any doors and corridors) are sufficiently
wide and the floor supports the appliance’s weight (the appliance’s weight and dimensions with/without
pallets are provided in the attached “Technical Data Sheet”). The appliance must be transported with
mechanical means (e.g. pallet jack). The installation rooms must be well-ventilated with permanent aeration
vents; must be equipped with the proper electrical and hydro systems, built in accordance with the
standards related to facilities and workplace safety in the country of installation.
The maximum working height, referring to the highest surface level, must be 1.6 metres from the floor.
After installing the appliance, if required, apply the suitable adhesive symbol (supplied) at a height of
1.6 metres. To favour air circulation around the appliance, leave a space of about 10 cm between the
appliance sides and the surrounding walls (or other appliance), and between the back and the back wall
(see the attached “Technical Data Sheet”). The appliance must be positioned so that the rear wall is easily
accessible to set up various electrical connections and to carry out any possible maintenance. Do not install
the appliance near any equipment that may reach high temperature values (e.g. deep fryers).
Should the appliance be installed near walls, shelves, counters and the like, these must be non-flammable
or heat-resistant; otherwise, they must be protected by adequate fire retardant coating. Accordingly, it is
indispensable to act in compliance with the fire prevention regulations in force.
Cooking produces hot smoke/vapour and odours which are extracted through the suitable vent device
located at the top of the appliance and marked with the symbol .It is recommended to place the

5
appliance under an extraction hood or to use the suitable TECNOEKA. condensation hoods in order to
convey the smoke/vapour to the outside.
Warnings
Make sure there are no objects and/or materials obstructing the oven’s exhaust device.
The hot smoke/vapour produced during cooking must run freely out of the exhaust device in order not to
compromise the regular operation of the oven.
Inflammable materials must not be left near the oven’s exhaust device.
3.6.1 Table top oven placement
The appliance must be placed in a perfectly horizontal position on a table or similar support; never on the
floor.To facilitate oven levelling, the feet are adjustable in height.
For safety reasons it is recommended to use the specific table produced by TECNOEKA; otherwise the
dimensions and weight of the appliance must be taken into account.
The appliance is unsuitable for recessed installation and cannot work without the 4 supporting feet.
Warning
If the appliance is positioned on a wheeled table/support, ensure that the intended movement does not
damage electrical wires, water pipes, drain pipes or anything else.
3.6.2 Stacking ovens on other appliances
When stacking two appliances only the specific “STACKING KIT” supplied by TECNOEKA can be used.
THE MANUFACTURING COMPANY DISCLAIMS ANY LIABILITY FOR DIRECT OR INDIRECT DAMAGE CAUSED TO THE
HOOD DUE TO FAILURE TO COMPLY WITH THIS DIRECTIVE.
For correct “STACKING KIT”installation operations, follow the instructions provided inside the package.
Warnings
An oven must never be stacked directly on another oven or another heat source.
If you have to use the "STACKING KIT" (to stack the appliances), be very careful not to damage the
"ON/OFF" button under the oven base (upper).
3.6.3 Placement of floor-standing ovens with trolley
The appliance must be positioned on a flat and level floor that can sustain the weight of a “full load”
without collapsing or deforming. After placement, make sure that the appliance is aligned horizontally. This
check may be carried out by placing a "spirit" or digital level on the 4 top sides of its casing.
Ensure that the tray trolley is able to go in and out of the cooking chamber easily, without rubbing against
the lower surface, even with "full load". Otherwise the appliance feet must be adjusted to lower it so that
the tray trolley can move properly. In any case, when the adjustment is complete, ensure that the wheels of
the tray trolley inserted in the cooking chamber are raised off the floor (by not more than 5 mm), and that
the trolley is supported by the guides at the bottom of the appliance.
The tray trolley must be moved using the supplied grip. The grip must be inserted into place at the front of
the trolley up to the "stopping point".
The tray trolley must be inserted inside the cooking chamber, freely sliding on the guides in the lower
portion of the appliance.
Warning

in the permanent connection to the electric power network, a protective pole switch must be placed
between the appliance and the mains (e.g. circuit breaker) with minimum opening between the contacts of
overvoltage category III (4000V) and a differential switch, sized for the load and complying with applicable
regulations.
the protective pole switch used for the connection is easily accessible when the appliance is installed;
the yellow/green earthing cable is not interrupted by the switch;
when the appliance is running, the power supply voltage does not deviate from the rated voltage value by
±10%.
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”).
3.8 Power supply cable connection (replacement)
The appliance is fitted with a power supply cable (except for models MKF 1664 BM and MKF 2011 BM)
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 left 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

Fig.2
Warning
To handle the detergent and for the maintenance of the washing water circuit, the appropriate DPI
(garments, splash visor, gloves, goggles) should be used: strictly follow the instructions on the detergent
safety data sheet.
3.11 Water drain
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 30) 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.

11
3.11.1 Water drain for floor ovens
The drain pipe is conveyed to an open (grilled) floor drain (Fig.3) and should not go into direct contact with
the discharge point: the "air gap" (distance between the drain pipe coming from the appliance and the
open drain) 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%.
Fig.3
3.11.2 Water drain for tabletop ovens
The exhaust pipe can be conveyed to an open (grilled) floor drain (Fig.4); otherwise, between the drain pipe
of the appliance and the drain point with a "collection cup" (Fig. 5), 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%.
Fig. 4 Fig. 5
3.12 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.

12
4. MAINTENANCE INSTRUCTIONS

4.2 Safety thermal device
The appliance is equipped with a (manually reset) safety thermostat, to protect against excessive and
hazardous overheating which might accidentally occur inside it. If the safety thermostat trips, the power
supply to the appliance is cut off.
The safety thermostat is located at the back (bottom) of the appliance (see the attached "Technical Data
Sheet"); to reset it after it has tripped, unscrew the protective cap using an appropriate tool and press the
"reset" button all the way. Replace the protective cap so that it cannot be unscrewed without the use of a
tool.
Important
The safety thermostat should only be reactivated after eliminating the functional anomalies that caused it
to trip. This can only be done by a Service technician.

13
4.3 Electronic circuit protection
The electronic circuit of the microprocessor cards housed inside the "electronic component drawer" is
protected by fuses. If they “blow” they must be replaced with equivalent fuses with the same electrical and
dimensional characteristics.
Important
“Blown" fuses should only be replaced after eliminating the anomalies that caused them to blow. This can
only be done by a Service technician.
4.4 Replacing the cooking chamber gasket
The cooking chamber gasket has a rigid profile with retaining fins. This profile must be inserted in
the suitable perimeter seat on the “front” of the chamber.
To replace the gasket, simply remove the used one from its seat (pull tightly near the 4 corners)
and, after cleaning any impurities from the seat, insert the new gasket (to facilitate the assembly,
it is recommended to wet the profile of the gasket with soapy water).
4.5 Handle closure adjustment
Should the door handle not close properly, check and if required adjust the position of the "nose" (cross-
shaped) as follows:
with the oven door open, loosen the 2 screws that secure the "nose" support;
move the support vertically (upwards or downwards) and fasten it so that when the door is pushed with
the handle completely open (horizontal position), the “nose” can fit into the handle without rubbing.
after adjustment, with the door closed, the handle must be in a perfectly vertical position (the end portion
of the "nose" must be perfectly horizontal).
Warning
The door handle must only be adjusted after positioning the oven in a perfectly horizontal (levelled) way.
4.6 Checking the cooking chamber gasket “seal”
If the gasket on the "front" of the cooking chamber does not ensure proper "sealing" on the inside glass
of the door, adjust the position of the 2 hinges (upper and lower) of the door and/or the (cross-shaped)
handle "nose" projection by doing the following:
Loss of “tightness“ on the hinges side
With the door closed, loosen the 6 screws securing the lower hinge (3 screws) and upper hinge (3 screws)
of the door; push the door slightly to the side of the hinges so that the inner glass leans on the "front"
gasket; hold the door slightly pressed in the direction of the hinges and secure them by tightening the 6
previously loosened screws. At the end of the operation, visually check, on the hinged side, that the door is
perfectly parallel to the "front" of the cooking chamber.

14
Loss of “tightness“ on the “nose” side
With the door open, loosen the locknut that secures the "nose" to its support; screw (clockwise) the
"nose" by a full turn so that the end (cross-shaped) piece is perfectly horizontal again; screw on the
previously loosened locknut. At the end of the operation, close the door, and check for slight resistance
when turning the handle: this means that the "front" gasket is pressing (“sealing”) slightly on the inside
glass of the door.
If you do not feel any resistance, repeat the entire operation by screwing on the "nose" another full turn.
Warning
After performing all the operations necessary to restore the proper “sealing” of the gasket on the inside
glass of the door, check its tightness by running the oven: for at least 30 minutes, with a 100%
humidification cycle and with a cooking chamber temperature of 110°C. During oven operation no steam
must escape from the door.
4.7 Residual risks
Do not use the door handle to move the appliance: this may deform the door frame.
The appliance is fitted with electrical parts: it must never be washed with a water or steam spray.
The appliance is electrically connected: disconnect the power supply before performing any type
of maintenance.
To avoid incorrect connections of the appliance, the relevant electrical/water connections are
marked on the appliance by suitable identification plates.
Only for wheeled models (MKF 1664 BM –MKF 2011 BM)
After installing the oven, ensure the tray trolley can be handled with ease, on smooth floors and
with no hindrance to insertion and extraction operations: the trolley is mounted on wheels, any
collision may cause the hot cooking food and/or liquids to spill and may even cause it to tip over.

7. TECHNICAL SUPPORT
Before leaving the factory this appliance has been calibrated and tested by experienced and skilled
personnel in order to obtain the best operating results. Any repair or calibration must be carried out with
the utmost care and attention, using only original parts.
That is why it is always necessary to contact the Dealer who sold the appliance or our nearest Technical
Support Centre, specifying the kind of failure and what model you have. For servicing needs the user may
contact Tecnoeka on the numbers shown on the cover, or refer to the website www.tecnoeka.com.
8. DISPOSAL OF THE APPLIANCE
In accordance with Directive 2012/19/EU on the disposal of waste electrical and
electronic equipment, the crossed-out wheeled bin symbol on the equipment
indicates that the product was placed on the market after 13 August 2015, and that
at the end of its services life it must be disposed of separately from other waste.
At the end of the appliance’s service life, the user must, therefore, deliver it to the
appropriate centres (recycling centres) for the separate collection of electrical and
electronic waste.
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.
9. 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

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

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.
10. 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.
11. 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
