• The conductivity sensor is equipped with a 2.9 long cable.
Conduct the cable through the opening marked on the next
page and connect it according to the wiring diagram in the
E-box.
• Look for a place where you can fix the conductivity sensor,
without that the cable is under mechanical tension.
• Loosen the union nut on the conductivity sensor, remove
the cutting ring and put it on the stainless steel pipe (item
4).
• Slide the nut over the stainless steel pipe and the cutting
ring and screw the nut onto the thread of the conductivity
sensor.
• Plug the connector (item 5) on the free end of the stainless
steel pipe.
• Screw the connector with internal thread (item 6) on the
connection for demineralized drinking water at the BNB
according to page 43, BNB manual.
• Plug the PE tube (item 7) into the connector (item 5) and
conduct it to the water supply of the BNB.
• Shorten the PE tube if necessary and put the free end into
the connector (item 6) at the water connection of the BNB.
• Attach the conductivity sensor.
• Position the ion exchanger (item 1) in the vicinity of the
conductivity sensor and connect the water outlet of the ion
exchanger and the conductivity sensor by the 1.5 m long
hose (item 2).
• Connect the water inlet of the ion exchanger and the water
supply (water tap) by the second hose.
• Connect the overflow pipe and resp. the waste water pipe
at the BNB humidifier according to the instructions on pag-
es 40-41 and 44-46 of the BNB manual.
