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 16 mm (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.
FIG. 1 FIG. 2
Steam outlet
The appliance is equipped with a special metal tube (DN30), to exhaust the steam from the
cooking chamber.
No other type of pipe can be connected to this pipe, which protrudes from the back of the
enclosure.
Failure to comply with this specific prohibition will allow the Manufacturer to reject any
responsibility coming from the possible malfunction of the appliance and the poor quality of the
cooking operations.
Increasing the length of the original exhaust pipe may cause abnormal condensation inside the
cooking chamber.
To prevent steam from escaping from the exhaust pipe, place the appliance under the
extraction hood.
Connection to water tank - (for ovens predisposed to water pump)
Warning:
To avoid limestone buildup into the cooking chamber, we suggest to fill the water tank with
decalcified water.
Check water level in the tank before activating the pump and during its functioning. If pump
works without water in the tank, what occurs is abnormal noise at first and then its breakage
.
