15.4 Checking the protective anode
» Check the protective anode after the first 2 years of use and
replace if necessary. To do this you must dismantle the flanged
immersion heater.
» Afterwards determine the time intervals at which further checks
should be carried out.
The transition resistance between the protective anode and
cylinder connector may be no more than 1.0 Ω.
15.5 Descaling the flange
» Only descale the flange after disassembly and never treat the
cylinder surface and protective anode with descaling agents.
15.6 Anti-corrosion protection
Ensure when carrying out service work that the anti-corrosion
protection on the insulating plate is not damaged or removed.
Reinsert the anti-corrosion protection correctly after replacement.
