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.

Step 1: Weld the adapter to the inlet pipe ("Figure 40:
Adaptor welded on inlet pipeline" on page 75) –
The material of the adapter 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 adapter ("Figure 41: Mounted
probe housing" on page 75) – 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 42: Mounted water detection
sensor" on page 75). Make sure there is no
leakage.
Step 4: Connect the water detection sensor to
the water detection sensor input NC and COM of
the PSk3 Controller, see also chapter "7.4.1.5 Pump
Accessory Wiring" on page 40. The polarity does
not matter.
Step 5: Fill the inlet pipeline, until only water ows
out of the vent valve. There must be no air bubbles
left in the water. Close the vent valve after venting.
