1. General information

These operating instructions contain basic information on what needs to be
considered during installation, operation, and maintenance of the equipment. They
must be read entirely by the fitter and operators before the equipment is installed
and taken into operation. They must always be kept close to the cooking site for
reference.

1.1 Area of application

“Berner” cooking units have been designed for the preparation of meals. They can
be used for cooking, keeping food warm, as well as for flambé singing, grilling,
etc. Note: Only use pans suitable for induction cooking with these units. You
should not use no-name products. The pan bottom must be magnetic. If in doubt,
check with the help of a magnet.

3.2 Installation requirements

The Induction-Unit has to be placed on a flat horizontal area. Don’t cover the air
supply for the air circulation. The place must be allowing a weight up to min. 40
kg. To disconnect the Power, the user needs easy access to the power-connection.

3.3 Installation instructions

The following Points must always be observed during installation:
Make sure that the main voltage corresponds to the voltage indicated on the

nameplate of the equipment.

- All electric installations must fulfill the local building code regulations. All
regulations issued by the national electricity authorities must be observed.

- The induction unit is equipped with a main cable and a plug which can be plugged
into a socket.

- When using fault-current circuit breakers, they must be designed for a minimum
fault current of 30 mA.

- Avoid blocking the air inlet and outlet zones with objects (textiles, walls, etc.).

- Prevent hot ambient air from being drawn into the induction unit (for example,
when several units stand next to each other, behind each other, or when the unit is
placed close to tilt fryers or ovens). In such cases, use a separate air duct.

- The induction unit must not be placed close to or on top of hot surfaces.

- The unit is equipped with a suction filter. Despite the presence of this filter, you
must still make sure that no greasy ambient air resulting from other activities can
be drawn into the induction unit (e.g. close to deep fryers, griddles, or tilt fryers).

- The temperature of the drawn-in air must be below +35°C.

- The personnel operating the equipment must make sure that all installation,
maintenance, and inspection work is done by specially trained and certified
personnel only.

3.4 Additional Installation instructions for the built-in Model

- The inlet air must be guided through an air duct and passed on directly to the fans
via the filters delivered with the equipment. The size of the air inlet should be at
least 200 cm².

- The inlet air upstream of the cooler fan must never exceed a maximum
temperature +35°C.

- Do not allow a “thermal closed circuit” to occur. Under no circumstances the
outlet air must be drawn in again, because this overheats the unit.

- After installation, the equipment’s functions must be tested. To do so, determine
the maximum cooling plate temperature. The temperature must be measured at the
cooling plate base, below the induction coil, which is located at the centre of the
equipment, close to the transistor module (large black block). In continuous

Ver.1.1

Page 6 of 21

operation of at least 2 hours and at an ambient temperature of 20°C, the
temperature must not exceed 50°C.

- All BI-Modelle (A105.950,A105.958,A105.968) have to be fastened.

- When using potentiometer lines, longer than 60 cm, the lines must be shielded and
connected to terminal S of the induction module.

- The main cable must always be shielded, clean contacts provided at both sides.

- Select and set up the main isolator so, that the equipment is switched on and off
no more than 5 times a day.

The Induction-Unit has to be equipped with right Cable and Plug for the
Regulations of the Country WHERE the Unit will be used.

Make sure that the plug is wired correctly:

For the electric Connection for the Unit take attention.
The Law Regulations of the Country have to be adhered!

Warning

Wrong Voltage can damage the

Induction Unit

The electrical Connection must only be

implemented by specially trained staff

Warning

4 Taking the Unit into Service

4.1 Unit Assembly

<Warning Electrical connections must be installed by trained staff personnel
only.>

Our induction units are equipped with one a main cable which must be connected
with a wall socket. If no plug has been installed at the cable, connect the plug as
described in chapter 3.
Electric installations must be carried out by registered installation companies
only, observing the specific national and local regulations. These companies are
responsible for correctly interpreting all regulations and performing the
installation in compliance with the safety instructions. Indications on warning
signs and nameplates must be strictly observed.

Make sure that the main voltage corresponds to the voltage indicated for the unit
(given on the nameplate).

The Induction-unit must always be installed on a clean, plain, and horizontal
surface only (table, cupboard, etc.). The equipment stands on non-slip rubber feet
which are permanently mounted. It must be placed so that it cannot fall down or
be moved due to a slanted position. Make sure that the requirements given in
chapter 3.1 “Installation requirements” are fully met.
