10.2.2 Steel/Stainless steel pipe

Step 1: Weld the adapter to the inlet pipe („Figure 41") –
The material of the adaptor must match the material of the
pipe. Both stainless steel and steel adaptors are available
from LORENTZ.
Step 2: Connect the sensor housing to the PTFE washer
on top of the adaptor („Figure 42") – Fasten the sensor
housing tightly and make sure that there is no leakage
at the PTFE washer. Connect the vent valve to the sensor
housing. The thread must be sealed; for example, PTFE tape
can be used as sealant.
Step 3: Put the water detection sensor into the sensor
housing („Figure 43"). Make sure there is no leakage.
Step 4: Connect the water detection sensor to the
water detection sensor input NC and COM of the
PSk2 Controller, cf. chapter "8.5.3 Terminal description" on
page 27. The polarity does not matter.
Step 5: Fill the inlet pipeline, until only water flows out
of the vent valve. There must be no air bubbles left in the
water. Close the vent valve after venting.

NOTE: The electrode sensor must be
cleaned regularly to prevent failure
caused by scale formation on the two
electrodes. Interval time depends on your
water quality.
