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.

8. Options

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.
