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.

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
mm

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.

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..

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 off-
the-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-the-
shelf products.

12. Informations to the consumers

Further to Directive 2012/19/UE, the symbol of the crossed rubbish skip on
the appliance means that at the end of its life, the product must be
disposed of separately from the other rubbish. The user must hand the
appliance to a specialised waste collection centre for electric and electronic
equipment.

The separate collection of the rubbish and subsequent treatment, recovery and disposal help to
produce other equipment using recycled materials, reducing the negative effects on the
environment and public health, which would be caused by incorrect management of the
rubbish.
Should the user dispose of the product abusively, administrative sanctions would be applied.
