3.8 Power supply cable connection

Remove the back and left side of the appliance to access the power supply terminal board.
Loosen the cable retainer at the rear (bottom) of the appliance (see Fig.1) and run the cable
through it until reaching the terminal board. Prepare conductors for connection with the terminal
board so that the earth conductor is the last to be extracted from its terminal in the event the
cable should be abnormally pulled. Connect the 3 phase conductors (L1, L2, L3) of the cable to
the terminals marked with “1”(brown conductor) “2”(black conductor) and “3”(grey conductor)
of the terminal board, the neutral conductor (blue) to the terminal marked with “4” or “5” and

the earth conductor (yellow/green) to the terminal marked with the symbol (see diagram also
available by the terminal board):

Tighten the cable retainer on the rear of the appliance; fit the left side and back on again. The
cable must be as per specifications in the "Technical features" table (paragraph 2.2). The
appliance must be connected to an equipotential system the effectiveness of which must be
suitably assessed according to applicable regulations.
This connection must be performed between different appliances through the suitable terminal
which is marked with the symbol . The equipotential conductor must have minimum section

2.5mm². The equipotential terminal is at the rear of the appliance.

3.9 Connection to the water mains
The appliance must be supplied with softened drinking water, with hardness between 0.5°F and
5°F. and maximum temperature 30°C. It is obligatory to use a softener to reduce the formation
of limescale inside the cooking chamber. The water pressure must be between 100 and 200 kPa
(1.0 -2.0 bar). If the mains pressure exceeds 2.0 bar, install a pressure reducer upstream of the
appliance. If the value is lower than 1.0 bar use a pump to raise the pressure. The appliance is
equipped with flexible hose (1.5 metres) with threaded ¾” female fittings and relevant gaskets.
The old joints must not be used. Connection to the water mains must be performed through the

¾” threaded solenoid valve located at the rear (bottom) of the appliance (see Fig.1), interposing a

mechanical filter and a stopcock (before connecting the filter drain off a certain amount of water
to flush the pipe from any dirt).

Warning

Any damage caused by limescale or other chemicals contained in the water are not covered by
warranty.

3.10 Water drain
A drain pipe comes out of the rear of the appliance (see Fig.1) to drain the cooking chamber.
This pipe must be connected to piping with 30 mm inner diameter (DN 30) resistant to steam
temperature (90°C-100°C).
To avoid choking the pipe should be stiff and there should be no "elbows" along the drain path.
The pipe must also maintain constant slope (min. 5%) along its entire length (the length
considered is that of the appliance's drain pipe at the drain point and must not exceed 2 metres).
The drain piping must be conveyed into an open floor drain (Fig.2); otherwise, there must be at
least 30 cm height difference between the drain pipe of the appliance and the drain point in order
to assure regular water drainage.
Furthermore, the minimum "air gap" must be 25 mm (distance between the drain pipe from the
appliance and the cup of the drain duct pipe).

Electronic convection oven rev. 5 _________________________________________MODELS EKF 464 TC – EKF 511 TC

_________________________________________________________________________________________ page 9

In any case, for reasons of compliance with health regulations in force, the piping connected to
the drain pipe of the appliance must not be in direct contact with the drain point.
It is recommended to connect the appliance's drain to the grey water network through an
adequate syphon, in order to stop steam from coming out of the drain.
The connection to drain water must be done separately for each appliance; in case of several
appliances connected to the same drain pipe, ensure the pipe is suitably sized to assure regular
drainage with no hindrances.

FIG. 2 FIG. 3

3.11 Safety thermal devices

4. Instructions for the user

4.1 General information

- Use the appliance at room temperature between +5°C and +25°C. 35°C may be reached

occasionally.

- The temperature of the appliance's external surfaces may exceed 60°C, only touch control

elements. Burn hazard!

- When the appliance is first used it is recommended to operate it unladen for 40/50 minutes at

a temperature of 220/230°C. In this way all unpleasant and wholly normal smells due to
heating the thermal insulation enveloping the cooking chamber and the silicone used for its
external sealing are dissipated.

- Supervise the oven during operation.

- This appliance must only be used for the use it has been especially designed for, that is

cooking food in the oven; any other use is to be deemed improper.

- The appliance may be used for all types of baking of pastries, baked goods and food: fresh and

frozen; for reconditioning chilled and frozen food, for steam cooking of meats, fish and
vegetables.

- No foods containing easily flammable substances must be cooked, such as alcohol-based

foods; self-combustion phenomena might occur leading to fires and explosions in the cooking
chamber.
Pay attention to handling food containers during and after cooking: they might be very hot.
Wear appropriate protective thermal clothing to prevent burns

- In placing the food in the cooking chamber, maintain a space of at least 40 mm between trays

in order not to excessively obstruct air circulation.

- Do not use trays with sides higher than necessary: the sides form barriers that prevent hot air

circulation.

- Preheat the oven every time before cooking to achieve top performance.

- For cooking as consistently as possible, spread the food evenly in every tray taking into account

its size, layer or thickness.

- Avoid adding salt to food in the cooking chamber.

- To check correct progress of the cooking cycle use the chamber's internal lighting: avoid

uselessly opening the door, which causes wastes of energy and longer cooking times.

Warnings
To prevent boiling, do not use containers filled with liquids or food that liquefy with heat, in
excessive amounts that cannot be easily kept under control. For this reason, only use trays that let
you see inside the container.
When extracting a tray containing hot liquid pay attention not to spill any liquid: burn hazard!

4.1.1 Residual risks

After baking open the door with caution, to avoid the violent outflow of heat which might cause
burns. During oven operation pay attention to hot areas of its outer surfaces (marked on the
appliance). Do not use the door handle to move the appliance (possible glass breakage).
The supporting bench must be able to withstand the weight of the machine and house it
correctly. The appliance is fitted with electrical parts and must never be washed with a water or
steam jet. The appliance is electrically connected: disconnect the power supply before performing
any type of cleaning. To avoid incorrect connections of the appliance, the relevant electrical/water
connections are marked on the appliance by suitable identification plates.
