HOW TO CHANGE COMPONENTS
The hot water tank is enamelled inside in order to protect against
corrosion.
In order to avoid corrosion completely an anode is mounted in the
middle and in the bottom (only by 2 coils) of the boiler. To inspect the
anode the front cover must be removed.
It must be examined once a year and replaced when the diameter has
reached 6-10 mm. The boiler of the heat pump is emptied by turning
off the cold water supply and then turning on the drain valve, which
must be mounted on the cold water inlet of the heat pump. At the same
time a hot water tap is turned on to avoid negative pressure inside the
tank.
To remove the anode use a 32mm socket.
