A.3.3 Function: Overflow
●
If a malfunction occurs (e.g. the inlet valve
does not close in time) water is discharged
into the overflow trap between boiler and
boiler insulation.
●
The water is led from the drain adaptor to
the drip tray.
●
The opening of the overflow is covered with
a rubber trap to prevent steam losses.
A.3.4 Function: Water Inlet
●
The water inlet is located on the bottom of
the container. It is connected to the inlet
valve by a hose connection.
●
The essential parts of the inlet valve are
(fig. 1):
-
the diaphragm with cleaning wire (1)
-
the tappet (2)
-
the coil
-
the valve housing (3) with sieve, flow
rate controller and outlet spout.
●
When the valve is closed, the tappet closes
the bore in the middle of the diaphragm.
