legal regulations;
- a omnipolar switch with minimum between-contacts aperture of the overvoltage
category III (4000 V), sized to the load and conforming to current legal regulations, is
fitted between the appliance and the mains in the direct connection to the mains;
- the omnipolar switch used for connection is easy to reach when the appliance is
installed;
- the yellow/green earth wire is not interrupted by the switch;
- the power supply, when the appliance is operating, must not deviate from the rated
voltage value by ±10%;
- make sure that after inserting the power supply cord into the terminal block it does
not come into contact with any of the cooking range's hot parts;
- if the supply cable is damaged then it must be replaced by the manufacturer or by
your technical support or by a qualified person to avoid any risk.
Connection to water mains - The oven must be supplied with softened drinking water
with a hardness value of 0.5 to 5°F (it is obligatory to use water softener to reduce the
formation of scaling inside the cooking chamber). The water pressure must be in the range
of 100 to 200 kPa (1.0 – 2.0 bar). If the water pressure exceeds 2.5 bar, install a pressure
reducer device upstream. If the pressure is below 1.5 bar, use a pressure pump to increase
the level.
Water drainage
A drain pipe comes out from the rear of the appliance, to drain the oven cavity. This pipe
must be connected up to a pipe made to resist steam temperatures (90°C-100°C) with an
internal diameter of 16mm (DN 16). To prevent choking, it is best to use a rigid pipe and
make sure there are no "elbow" bends anywhere along the drain line.
Furthermore, the drain line must slope down (minimum slope 5%) along its full length (the
length in question is from the appliance's drain pipe to the drain point and must not exceed
2 metres). The drain line must run into an open floor drain (Fig.1). In addition, there must be
a free air gap of at least 25 mm (distance between the drain line coming from the appliance
and the funnel on the drain standpipe). Whatever the case, in order to comply with current
hygiene standards, the line connected to the appliance's drain pipe must not come into
direct contact with the drain point. It is advisable to include a suitable trap in the line
connecting the appliance's drain outlet to the grey water waste system, thus stopping the
steam coming back out of the drain.
