3. INSTALLATION
ATTENTION! These installation instructions are for the
exclusive use of personnel qualified in the installation and
maintenance of electrical equipment. Installation by unqualified
persons could cause damage to the oven, to people, animals or
property.
In addition, where modifications or adaptations need to be made to the
electrical systems in the building where the machine will be installed,
whoever carries out such modifications must certify that the work has
been undertaken according to current regulations in the country where it
is installed
3.1. Checking upon delivery
Unless otherwise agreed, the products are carefully bubble wrapped in
a robust wooden structure to protect against knocks and humidity during
transport, and are delivered to the carrierin the best condition.
We recommend, however, that you check the packaging on arrival for
any signs of damage. If there is damage, 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 carrier 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.
3.2. Choosing a place for installation
The appliance’s effective, safe and long lasting operation 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.

3. INSTALLATION
TEOREMA POLIS PW

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
“TEOREMA POLIS PW” cooking
units, 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, the cooking equipment produces vapor and cooking
smells that compromise the integrity of a healthy working environment.
In the case of electric ovens, although 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 Annex A) even when the oven itself or other ovens in
the room are functioning.
Exceeding the temperature or the maximum relative humidity values
can easily and unexpectedly damage electrical equipment creating
hazardous situations.
The manufacturer cannot answer for damage caused by
ignoring these abovementioned norms regarding the equipment’s
proper installation

3.3. 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 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 gravity.
Take care that children do not play with the packaging
materials (e.g., plastic sheeting and Styrofoam): suffocation danger!

3.4. Positioning and mounting the unit
1 - Position the module on the
base /cell/other unit, manoeuvring
it as described in paragraph 3.3
(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,
use high heat silicone to seal
around the vapor exhaust tubes
at the back, at the point where they join.
3.5. 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 Annex A).
The appliances are supplied with an earthed electrical cable for
connecting the appliance to the power grid according to the supply
required (see Annex A).
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.

3. INSTALLATION
TEOREMA POLIS PW
12
The power cable must terminate with a plug to connect to the electrical
panel having a corresponding Residual Current Circuit Breaker with Over
Current Protection.
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. 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 device must be calibrated to the 30 mA current (see Annex A).
The electrical socket must be easily accessible and must not need moving
after equipment installation. 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 replaced 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 Annex B.
3.6. 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 type of oven so as to guarantee
the sustainability of a healthy working environment. For more
information it is recommended that specific norms be consulted.

The Manufacturer cannot answer for damage caused by ignoring
these abovementioned norms as well as the information in this
manual.
To locate exhaust see Annex B
3.7. Checking before starting work
After completing installation of the unit a series of checks must be carried
out, listed as follows:
- check that the various disassembled parts have been assembled
- check the electrical power connections;
- check that the control panel is working
- If present, check that the ventilation hood is working
IMPORTANT –TURNING ON FOR THE FIRST TIME
The components of a factory new oven (cooking surfaces of refractory or
sheet metal material) need to be subjected to an initial preheating.
BRINGING THE OVEN UP TO TEMPERATURE OVER A PERIOD OF 5-
6 HOURS (1°h=100°C - 2-3°h=150°C - 4°h=200°C - 5°h=250°C -
6°h=300°C); the first time the oven is turned on this is an
INDISPENSIBLE procedure to avoid possible damage to the above
mentioned parts.
