6 Fitting the TDS probe
It is essential to remove the cardboard protective tube for transport before
installation!!
If several probes are screwed into one flange, the probe plug and the
associated probe should be labelled to prevent confusion!
Screw connection of the TDS probe
• Unscrew the probe plug
• Clean and check sealing surfaces
• Insert (new) sealing ring
• Grease the thread with heat-resistant solid lubricant (e.g. graphite).
• Screw in and tighten the probe, max. tightening torque Md = 140 Nm.
• Fit into the boiler before connecting the power.
Do not seal thread with PTFE tape or the like!
When commissioning the boiler, check the probe screw connection in the
flange for leaks and retighten if necessary!
