Electrical Connection - De Dietrich AD199 Instrucciones De Montaje Y Conexión

All connections are realised on the terminal blocks provided for
this purpose at the back of the boiler control panel.
The sensor cables have to be separated from the 230V
circuit cables :
- In the boiler : use 2 grommets on each side of the boiler.
- Outside the boiler : Use 2 pipes or cable guides at least 10 cm
apart.

Fitting the flow sensor
The flow sensor with connecting cable (length 2.5 m) and connector
plug should be fitted to the outlet circuit pipe concerned and must be
connected to the point provided in the control panel shown below.
- The flow sensor after the valve must be positioned around 0.5 m
after the 3 way valve or after the heating pump if this is fitted to the
outlet.
- Cut the pipe insulation by 50 mm
- At the point where the sensor is fitted, thoroughly clean the pipes
(there must be no trace of paint) and coat them with the ready-to-
use contact paste provided in the syringe.
- Secure the sensor with the collar provided for this purpose.
The flow sensor must not be covered by the insulation around
the pipe.
