2. EVERY 6 MONTHS

The magnesium anode is an anti-corrosion element. It is assembled in
the water tank to avoid corrosion inside the heat pump boiler tank,
to protect the heat pump boiler tank and other components. The
magnesium anode is crucial to the life-span of the heat pump boiler.
• Check the magnesium anode every 6 months and replace it if it has worn out.
• If, during the first three inspections (with max. 6-months interval), one can
experience that the wearing down time of the Magnesium anode is 12
months or more, than –based on this experience- the inspection interval of
the magnesium anode can be extended to the maximum of 12 months.
1) Make sure to write down the actual installation date on the sticker on the
unit.
2) In the first cell: mark the date which the magnesium anode must be checked
again, this date to be maximum 6 months away from the date of installation.
3) On or before the date as mentioned in 2.: check the magnesium anode.
4) Mark that the magnesium anode was checked with "√" in the dedicated area.
5) For your own reminding: write down the next date on which the magnesium
anode must be checked again (max 6 months from date as mentioned in 2.)
• How to check/replace the magnesium anode.
1) Turn the power of the heat pump boiler 'OFF' and pull out the plug.
2) Drain the water out of the tank. See chapter D.1
3) Remove the old magnesium anode from the tank by turning the magnesium
anode anti clockwise.
4) Replace the magnesium anode for a new one when:
- The average diameter of the anode is less than 10 mm
- Or the average length is less than 150 mm
- Or the magnesium anode looks so much worn out that on some spots
down the length of the anode the diameter is certainly less than 12 mm.
Otherwise reposition the disassembled magnesium anode. Mind to reinsert
the rubber sealing ring.
5) Recharge the heat pump boiler with water. See chapter D.1
