4. INSTALLATION
ATTENTION: these installation instructions are for the exclusive
use of personnel qualified for the installation and maintenance of
electrical and gas equipment conceived for professional use in the
foodservice industry and community catering operations. An
installation carried out by unqualified persons could cause damage
to the oven, to people, animals or property.
ATTENTION: Proceed with the installation according to those
norms in force in the country where it is being carried out.
In addition, where it is necessary to carry out modifications or adaptations
to the electrical or gas systems of the building in which the oven will be
installed, whoever carries out such modifications must certify that the work
has been undertaken according to current “best practices”.
4.1 Checking on delivery
Unless otherwise agreed, the products are carefully packaged in a
robust structure in wood and with a sheet of nylon bubble wrap giving
protection against knocks and humidity during transport. These are
consigned to the freight operator in the best of condition.
We recommend, however, that you to check the packaging on arrival for
any signs of damage. If damage has occurred, have it noted on the receipt
which must be signed by the driver.
Once the equipment has been unpacked, check that it has not suffered
damage. Also check that all the dissembled parts are present.
In the event of damage to the equipment and/or missing parts, bear in
mind that the freight operator can only accept claims within 15 days of
delivery and that the manufacturer cannot be held responsible for damage
incurred to its products during their delivery. We are however, available to
assist you in presenting your claim.
In the event of damage do not try to use the equipment and
consult with professionally qualified personnel.
4.2 Choosing a place for installation
An effective, safe and long lasting functioning of the appliance also
depends on the position in which it is installed. For this reason, it is
advisable to carefully consider where to install the equipment before it is
delivered.

4. INSTALLATION
12
Fig. 4.1
Install the appliance in a dry and easily
accessible place both to facilitate its use
and to carry out cleaning and
maintenance. The area around the
equipment must be kept clear. It is
particularly important to avoid obstructing
the cooling outlets located at the sides of
the equipment.
When choosing a place to install the
cooking units “TEOREMA POLIS PW”,
bear in mind that they must be completed
with other units in the series: hood, chamber, base.
The appliance must be installed at least 20cm from the walls of
the room or from other equipment so that the ventilation outlets
located on the sides of the oven are not obstructed.
Whilst in operation, cooking equipment produces vapor and cooking
smells that compromise the integrity of a healthy working environment
In the case of electric ovens, even if it is not obligatory, the
installation of an extraction fan and hood is recommended to improve
conditions in the working environment and to avoid damage to the ceiling
of the area where it is housed caused by hot, oily fumes.
A check must be made to ensure that the temperature and relative
humidity never exceed the maximum and minimum values indicted in the
specifications (see paragraph 3.4) even when the oven itself or other
ovens in the room are functioning.
Exceeding these values especially the temperature or the maximum
relative humidity can easily and unexpectedly damage electrical
equipment creating hazardous situations.
The manufacturer cannot answer for damage caused by ignoring
these abovementioned norms as well as the information in this
manual.

4. INSTALLATION
13
4.3 Moving the unit
To unload and transport the unit while it
is packed, a pallet truck or a transpallet
lifter with a load capacity at least equal
to that of the unit should be used,
inserting the forks in the spaces
provided at the base of the packing.
To transport the module without
packing, use ropes or straps (certified
as suitable for lifting heavy loads)
threaded through the rings on the top of
the oven and lift with a fork lift truck
(Fig.1).
DO NOT raise the module by inserting forks or bars inside the
cooking chamber because this could cause damage the refractory
material at the top of the oven.
In all situations, to avoid unpredictable movement, be aware of
the equipment’s centre of mass.
Take care that children do not play with the packaging materials
( e.g., plastic sheeting and Styrofoam): suffocation danger!

4.4 Positioning and mounting the unit
1 - Position the module on the base
/cell/other unit, maneuvering it as
described at paragraph 4.3 (Fig.2)
2 - Allow the four fixing
Flanges on the corners of the oven
to drop into position (Fig.2)
3 - Secure with the screws provided
(Fig.2)
NO MORE THAN 3 UNITS
SHOULD BE STACKED ONE ON
TOP OF THE OTHER
When one or more units is
mounted on top of another, seal
the gasket around the vapor
exhaust tubes at the back, at the
point where they join. Use high
temperature resistant silicon for this.
4.5 Electrical connection
Before making any connection, check that the specifications of the
electrical supply to which the equipment must be connected, correspond
to the specifications of the power supply required by the apparatus itself
(see Tab. 3-1).
The appliances are supplied with an electric connection with
ground/earth cable for connecting the appliance to the power grid
according to the supply required (see cap. 3.4 Tab. 3-1).
In compliance with the safety norms in force. It is obligatory to connect
the ground/earth cable (yellow-green) to an earthing system with the
same dispersion capacity as the appliance itself. The efficiency of
this system must be correctly verified according to the norms in
force.
2

4. INSTALLATION
15
The power cable must terminate with a plug to connect to the electrical
switchgear having a corresponding differential magneto thermal switch.
The equipment is not supplied with a power plug.
The coupling between plug and socket must be such that the earth
conductor is connected first and disconnected last and must have the right
dimensions for the rated current (see Table 3-1). Plugs and sockets for
industrial use of the type CEE17 are suitable or those which satisfy
European norm EN 60309.
The thermal circuit breaker must be calibrated to the total rated current
and the magnetic circuit breaker calibrated to the rated current (In the
case of ovens this is only slightly higher than rated current), while the
differential mechanism must be calibrated to the 30 mA current (see Table
3-1).
The electrical socket must be easily accessible and must not require
further location after the installation of the equipment. The distance
between the equipment and the socket must be sufficient to avoid
stretching the power cable
The power cable must never be trapped under the feet or
wheels of the equipment
If the Power cable is damaged it must be substituted by
customer support or by a qualified service engineer so as to avoid
any risk.
The manufacturer does not accept responsibility for damage
caused by failure to observe the abovementioned norms.
For the position of the electrical power connections, see Fig. 4-2.
4.6 Emissions from cooking appliances
ATTENTION! Proceed with the installation of the oven
according to the norms defined by current legislation in the country
concerning the installation of this typology of oven so as to
guarantee the sustainability of a healthy working environment. For

6. FUNCTIONS
6.1 System functional states
6.1.1 Standby on/off button
When on standby the panel is powered but no system function is enabled.
The general remote switch is disabled and the message OFF is displayed
on the set display on the control panel along with the current time
on the display with flashing seconds dot (between the second
and third figure, ½ second on, ½ second off).
All buttons on the panel are disabled except for the button (system on)
and the key, pressure on which will bring the system to clock setting
mode (see “programming” section).
Pressing the button, the system comes on, the last SET temperature
programmed is displayed on the set display , and the cycle used
prior to switching the oven off is displayed on the display.
6.2 Settings
6.2.1 Set temperature setting
To set the SET temperature use the and buttons until the desired
baking temperature appears on the display.
6.2.2 Upper and lower element setting
Pressing the buttons varies the time the oven heating elements remain
on. Each time the button is pressed increases this value by 1 unit, up to a
maximum of 9 units. Further pressure returns the value to 0.
NB. Each unit on the two displays corresponds to 5 seconds element on
time. For the remaining units the elements remain off. The total duration of
the cycle is 45 seconds.
The on time of the two elements can be varied at any time, even during the
baking cycle. The upper elements during the first part of the cycle while the
lower ones come on during the second.

6. FUNCTIONS
19
For example, setting the upper elements to 6 and the lower ones to 5 gives
the following result:
5 10 15 20 25 30 35 40 45
Upper ON OFF
Lower OFF ON
Note that with this setting, for the first 20 seconds only the upper elements
are on, so the oven uses half the total power. Over the next 10 seconds
both the upper and power elements are on, with the oven using full power.
In the remaining 15 seconds, on the lower elements are on, so the oven
once again uses half its available power.
6.2.3 Economy button
Pressing the economy button sets power values to pre-set levels
(upper 5 and lower 3) with the following result:
5 10 15 20 25 30 35 40 45
Upper ON OFF
Lower OFF ON
Note that with this setting, in the first 25 seconds only the upper elements
are on, with the oven using half power. Both elements are off for the
following 5 seconds. In the remaining 15 seconds only the lower elements
are on and so the oven once again uses only half power. This means that
throughout the cycle the oven never uses more than half power and for 5
seconds power consumption is zero.
A similar result can be obtained through manual power settings, if the sum
of upper and lower times is less than or at most equal to 9.
6.2.4 Start/Stop button
Pressing the start/stop button starts the baking cycle according to the
previous setting.
6.2.5 Oven light button
Pressing the oven light button switches on the light in the oven. Press
again to switch it off.

6. FUNCTIONS
20
6.2.6 Switch for suction hood - Light switch for
steam generator
The switch for suction hood control is
placed on the side part of the suction
hood, on the upper side (Pos.1 of Fig.
6.1).
Push this switch on position “I” to start one
of the two motors of the suction hood.
Push this switch on position "II" to start
both motors of the suction hood. Push this
switch on position “0” to stop it.
On the side part of the control panel, you
find the light switch that starts and stops
the steam generator, if the oven is
equipped with this accessory (see Pos.2 -
Fig. 6.1).
6.3 Programming
6.3.1 Clock and day setting
The time and day can only be set with the system on standby, that is to say
when the display “OFF”.
