The appliances are equipped with a connection for the pipe for the water drained during the washing
process. A 3” elbow-joint and two metal strips are also provided to connect the appliance discharge to the
sewer collection service. Refer to the figure to identify the drain pipe fitting.
Make sure that the distance between the appliance drain connection and the floor drain is not greater than
the supplied elbow-joint length.
Water is drained via a motorised valve, which remains open if no voltage is available.
Some special versions are equipped with a second drain to recover the water of some washing phases.
Follow the special instructions provided with the special version.
4.6.4 DISCHARGE PIPE CONNECTION
Earthing techniques.
There are different types of earth systems on the market, but for all systems, the objectives are identical:
•
Limit the potential of the active wires compared to the earth in normal operating mode.
•
In the event of an isolation defect, limit the voltages between the masses and the earth.
•
Allow the intervention of the protection devices in order to eliminate the earth fault.
•
Limit the raising of the potential due to faults resulting from the medium voltage network.
•
Limit the raising of the potential when the atmospheric discharge affects the installation or the
power supply network.
Some examples.
Attention!
•
The drain duct must always be lower than the appliance outlet and
its diameter must not be lower than that of the supply pipe.
•
The drain duct must resist temperatures of 90 °C.
•
Place a syphon between the provided pipe and the drain duct.
•
Make sure there are no bottlenecks.
Attention!
•
Installation must be carried out according to the manufacturer's
instructions by qualified and certified personnel, in compliance
with Standards in force regarding electric systems both at national
and local level.
•
Incorrect installation can cause injury to persons and animals and
damage to objects and the environment in general, for which the
manufacturer is not liable.
