7.4 Taking the humidifier out of operation
If the humidifier is out of operation for a longer period of time ( e.g. in summer or when the air conditioning system
is not operating), the steam cylinder must be emptied and the power supply disconnected.
All options can be fitted either at the factory or subsequently.
Proportional adaptor
The steam output of the econoVap can be set anywhere between 20 % and 100 %. The proportional adaptor can be
simply inserted onto the electronic controls unit.
Following signals can be processed by the adaptor:
Voltage:
0–2 V; 0–5 V; 0–10 V; 0–16 V; 0–20 V (SCS); 1–5 V; 2–10 V
Current:
0–20 mA; 4–20 mA
Potentiometer:
min. 135 Ohm
SC-System
The SC-System is a patented self-cleaning system for the electrode steam humidifiers of NORDMANN.
The minerals are kept in suspension and as such are kept to a large extend from building up at the bottom of the
cylinder. The suspended minerals are flushed away during the normal drainage operations. The service life of the
steam cylinder is lengthened considerably and maintenance is made easier.
Cabinet Heating
Is the unit installed in an environment presenting the risk of frost, then the option “cabinet heating” is used.
It prevents the water in the steam cylinder from freezing.
