definitions
1. NKBD
2. Drinking water supply (on site)
3. Water demineralisation system (reverse osmosis system)
4. Demineralised water:
1 bar < pressure ≤ 4 bar
5 µS/cm < conductivity ≤ 20 µS/cm
5. Concentrate
6. Stop cock (included in the scope of delivery)
7. Water supply for plastic tube Ø 10 mm
8. Water overflow and discharge, for plastic tube Ø 14 mm
9. Drainage (on site)
Connections 7-8 are marked with stickers.
Important notes:
The NKBD may be operated with fully demineralised water only (produced for example by a re-
verse osmosis system). The demineralised water must have a conductivity of min. 5 µS/cm and
max. 20 µS/cm.
The contamination of drinking water may not exceed the max. values laid out in the drinking wa-
ter regulations
The demineralised water is corrosive, therefore use stainless steel or plastic only. Non-ferrous
metals (e.g. copper, brass) must not be used.
Water pressure must be minimum 1 bar and maximum 4 bar.
The drainage system on site must be set in accordance with DIN 1988 part of 4, EN 1717.
For easy revision, the stop cock included in the scope of delivery must be installed in the
demineralised water supply line close to the device.
All materials coming into contact with the demineralised water must be resistant
to demineralised water. Observe pressure and temperature resistance.
Demineralised water pipes must be flushed prior to starting the humidifier.
