NOTICE
Risk of device damage by calciferous water or wrong rong connected tanks.
∙ Use only distilled water for the H
2
O storage tank to keep the steam generator
maintenance-free.
∙ Make sure that the tanks are connected correctly. If the wrong tank (e. g.
reagent tank containing NaOH) is connected to the pump labelled as „H
2
O“, the
steam generator will get damaged.
5.8 Level sensors
Four capacitive level sensors are contained in the standard delivery of the instrument. Three are
intended for the storage tanks (NaOH, H
3
BO
3
and water) and one for the waste collection tank (either
the sample tube or receiver waste). Additional level sensors are available as optional equipment. Each
individual sensor is connected to the corresponding socket on the rear side of the device (see section
5.2.1).
The sensitivity of the capacitive level sensors can be adjusted to safely detect the liquid level, if neces-
sary.
Assemble the level sensors according to the following picture:
Fig. 5.14: Assembly of the level sensors
∙ Mount the sensor at the tank using the provided O-ring (see
1
in figure 5.9) and connect it at
the rear-side of the device to the corresponding port (NaOH, H
2
O, H
3
BO
3
, Waste Sample Tube,
Waste Receiver, or Titrant).
The sensitive side of the sensor (marked with the crosshair)
has to face the tank!
∙ Make sure the tank is filled with the corresponding liquid.
∙ Shift the sensor together with the rubber strap until it is located below the liquid level.
