7.5 Anode Replacement
1. Inspection of the elector for anode replacement
As soon as the function meter of the elector indicates „0“ during
the heating period the anode needs to be inspected and possibly
replaced. Proceed as follows:
- Close the in- and outlet of the elector
- Put a bucket to the drain of the elector
- Remove the deaerator (if detachable), open the drain valve and
drain the elector
- Remove the plastics cap to the top
- Disconnect the orange plug contact
- Remove the insulation fleece and the electrical contact
- Depending on the elector version the housing is closed by a
flange or a brass plug. Remove either the flange or the plug
together with the old anode. Check the anode
a) If the anode is worn out you should install a new anode.
b) If the anode still looks good but the indicator has shown
„0“ there might be on oxide or chemical layer on the anode
surface blocking the flow of the electrons. Clean the anode
with a wire brush to remove the layer on the anode surface.
If the indicator does not show any reaction test the indicator
with a 1.5 V battery on its function. Replace the indicator if it
does not show any reaction while testing it with a battery.
2. Installation of a new anode
If the anode is completely used install a new one as follows:
- he anode is fixed at the anode stabiliser screw that goes either
straight through the flange or the brass plug.
Do not remove the
anode stabiliser screw.
- Sometimes you cannot see the stabilsier screw due to heavy
impurities. Clean the screw with a wire brush for full access to the
construction.
- Fix the anode holder screw and release only the small screw on
top of the anode.
- Replace the old anode with a new one and make sure that the
small screw on top of the anode and the anode stabiliser screw
have good electrical contact with each other.
- Make sure that the anode stabiliser screw is fixed thightly to the
flange or the brass plug.
- Replace the flange gasket or the o-ring seal.
- Reinstall all electrical contacts, the insulation fleece and the cap.
- Refill the elector with water and open the in- and outlet of the
device.
