Anti siphon
Dishwashers equipped with Anti-Siphon device can be installed in an elevated installation.
The drainage hose can run to a lower level than the bottom of the dishwasher without emptying the
dishwasher of water during the wash cycle.
The Anti-Siphon device acts as a pressure equalizer which ensures that over- or under-pressure never
occurs in the machine. This prevents the machine from either being emptied of water or sucking water
from the drain. As an extra security measure the drain hose is fitted with a check valve.
The anti-siphon device is placed
on the left side of the dishwasher.
The drainage hose may be extended by a maximum of 3m (the total length of the drainage hose
must not exceed 4,5m). Any joins and connecting pipes must have an internal diameter of at least
14mm.
