Unox ChefTop Gas Manual De Instrucciones página 23

The use of a safety switch for fault current is suggested.
When the appliance is working, the power supply voltage
must not diverge from the value of the nominal voltage,
indicated on the data plate, by more than ± 10%.
3.2 CONNECTION TO THE ELECTRICAL SUPPLY
MAINS
UNOX gas ovens are equipped with electrical cable and
Schuko plug (monophase 230V) that has to be simply
plugged in a proper outlet (check the outlet is suitable to
the supplied Schuko plug).
Pay attention on plugging in the equipment: in case the
oven locks at any time the flame lighting starts try to turn
the plug of 180 degrees (on board safety system that
avoid Phase-Neutral polarity inversion).
The electric supply outlet must be clean, in good
conditions and far from fats, oils and other sub-
stances that may compromise the electric connec-
tion.
3.3 EQUIPOTENTIAL SYSTEM
The appliance must be included in an equipotential system
whose efficiency must be properly checked according to
the current laws. This connection must be done between
different appliances through the terminal marked with
the symbol: simbolo morsetto equipotenziale
The equipotential conductor must have a minimum sec-
tion of 10 mm .

4.1 WARNING
Before proceeding with the gas connection, the qualified
installer must check the data indicated on the technical
data plate match with the available gas type.
The equipment is set and tested in production for LPG
gas, G30 type (butane/propane G30/G31) at a nominal
pressure value of 28-30/37 mbar.
In case the gas available to be connected to the equip-
ment is different from the gas the oven is set to, see para-
graph 4.3.
4.2 CONNECTIONS
The equipment has to be connected to the gas accord-
ingly to the standard in force.
Install an interception gas cock between the equipment
and the gas supply in an accessible position.
The connection to the gas main, through the ¾" ISO 7-
1 type fitting placed on the back left panel of the oven,
can be made by using flexible or not flexible pipes and by
placing an approved interceptiongas cock between the
equipment and the gas supply.
In case flexible pipes are used, make sure they are made
in stainless steel, not placed close to external heat sources
(e.g.: fryers, open burners etc.) and not subject to twist-
ing and/or traction.
In case non metallic material are used, e.g.: sealing, they
must be certified and complying with the European stand-
ards in force.
Check the gas circuit seal by putting on the fittings a suds
solution or non corrosive specific foaming products.
Important: never use a flame to check possible gas leaks.
4.3 SET AND ADJUSTMENT TO DIFFERENT GAS TYPES
Before carrying out work on the appliance, close the gas
cock and disconnect the electrical supply.
The accommodation has to be made by qualified person-
