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.
2.10.1 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).
Fig.1
Warning
Any damage caused by limescale or other chemicals contained in the water are not covered by warranty.

2.11 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.
2.11.1 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%.
Fig. 2 Fig. 3
2.12 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.

4. CLEANING
4.1 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.
4.2 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.
4.3 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.
4.4 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.

4.5 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:
fully open the door;
open the door;
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.

4.6 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.
4.7 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.
5. MAINTENANCE INSTRUCTIONS
A periodic check (at least once a year) of the appliance contributes to extending its service life and assures
proper operation.
Any maintenance operation on the appliance must only be done by highly qualified personnel trained in
the operations being performed and authorised by TECNOEKA. Operations must be carried out in
accordance with the safety regulations in force in the country where the appliance is installed, pursuant to

power supply to the appliance is cut off.
The safety thermostat is located inside of the appliance.
Important
Safety thermostat should only be reactivated after eliminating the anomaly that caused them to trip. This
can only be done by a Service technician.
5.3 Replacing cooking chamber gasket
The cooking chamber seal has a rigid profile with retention tabs. This profile is inserted into the
perimeter seat on the 'front' of the chamber.
To replace the gasket, simply remove the used one from the housing (pull firmly at the 4
corners) and, after cleaning the housing of any impurities, insert the new gasket (we recommend
moistening the gasket profile with soapy water to facilitate assembly).

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.
