The appliance must be fed with softened drinking water
from 0.5°fH to 3°fH and at a maximum temperature of 30°C.
Using a water softener is compulsory
chamber (oven cavity).
Water pressure must be in the range from 100 to 200 kPa (1.0-2.0 bar). If the mains pressure is
higher than 2.0 bar, install a pressure reducer upline from the appliance. If the value is less than
1.0 bar, use a pump to boost pressure.
The appliance comes with a hose (1.5 metres) with 3/4" threaded female fittings and relevant
seals. Old seals must not be reused.
Connect the appliance to the water mains by means of the 3/4" threaded solenoid valve on the
rear of the appliance (at the bottom) (see Fig.1), fitting a mechanical filter and an on/off valve
between the appliance and mains (before you connect the filter, allow a certain quantity of
water to flow out in order to flush any waste from the pipe).

A drain pipe (see Fig. 1) 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 30 mm (DN 30). 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.2). 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.
