7. Fitting the electrode
It is essential to remove the protective tube for transport before
installation!
If several electrodes are screwed into a flange the electrode plug (2)
and the associated electrodes should be labelled to prevent confusion!
Fixing the electrode extension (9)
Push the electrode extension (9)
approx. 30 mm over the electrode shank
(8) until the ø 4.3 mm hole
matches the threaded hole
in the electrode shank.
Screw up both parts by means
of the enclosed M4 set screw with
SW2 hexagon socket.
Screwing in the electrode
•
Release screw (1) and pull off
electrode plug (2).
•
Clean sealing surfaces and check
•
Insert sealing ring (6)
•
Lubricate thread (7) with heat-resistant
solid lubricant (e.g. graphite).
•
Screw in electrode and tighten,
max. tightening torque Md=140 Nm.
On commissioning the boiler
check the electrode screw connection
in the flange for tightness and if necessary
retighten!
