Valve does not close correctly
If the valve does not close correctly, then the full line pressure
is present (with on-site demineralised water connection) and the
steam generator is flooded.
As the pressure on the steam generator is regulated, the
heating may not be switched on in some circumstances.
If the line pressure exceeds the permitted excess operating
pressure of the safety valve (SV1 – see Tab. 11: unterhalb)
then demineralised water escapes from the device.
Electrodes
The low electrode (E2) protects the heating (H1) and the high electrode
(E1) switches the water feed pump (M1). This regulates the level of water
in the steam generator.
