in force.
VI. WATER CONNECTION
A cut off tap and a mechanical filter shall be interposed between water supply system and the oven. There is
a G3/4’’ input on the back of the oven with a filter. There is also a 2m pipe with G3/4’’ fittings and check
required by law. WARNING: only use the material supplied to connect the oven (pipe with fittings and check
valve) and do not use or re-use other pipes. Before connecting the pipe to the appliance, let the water flow
out to get rid of residues in the pipe. The inflowing water shall have a pressure value comprised between 150
(1,5 bar) and 200 kPa (2bar) and a maximum temperature of 30°C. If the inflow pressure value exceeds
200kPa (2bar), a pressure reducer will have to be installed, calibrated at 200kPa (2 bar).
WATER TREATMENT
The water shall have a maximum hardness of 5 °F. Use of demineralising appliances is recommended
(Reverse Osmosis) with the aim of avoiding deposit of limestone and other minerals in the appliance.
VII. DRAINAGE CONNECTION
WATER DRAINAGE
Water flowing out from the appliance drainage system may reach high temperatures (90°). The pipes used
for discharging the water must be capable of bearing such temperatures.
The discharge water pipe is located in the lower rear part of the back of the appliance and it should be
connected using a rigid or flexible pipe and conveyed to an open or trapped drainage; its diameter shall not
be smaller than that of the drainage connection of the appliance. It is advisable to insert a suitable syphon
between the appliance and the drain, so as to stop emission of unpleasant odours and fumes from the
appliance and drains.
Avoid narrowing the flexible pipes and elbow joints on rigid pipes along the entire drainage system meter.
The appliance must have its own drainage connection. If there are other appliance or tools connected to the
one pipe, check that their size allows proper drainage without blockage.
The local regulations and standards must be followed.
