Control safety anode

(Only for models with stainless hot water cylinder)
At the top of the hot water cylinder, under the insulation, there is an electronic protection anod (standard
feature) Its purpose is to prevent corrosion. The cylinder must be full of water for the anode to work.
If the heat pump is equipped with a magnesium anode, the anode can corrode depending on the water
quality. If its diameter has been reduced to a minimum it must be replaced. This is how you check the
magnesium anode:
1. Shut off the main cold water feed.
2. Turn on a tap to reduce the pressure in the water cylinder.
3. Unscrew the anode and check it.
If the anode is electronic there is a control panel with LEDs where you can see the status of the anode. It
shows a red or a green light. If the LED shows green, the anode is operating and working normally. If
large amounts of hot water are drawn off (when filling a bath for instance) the LED may show a red light
for a short time even though there is no fault. If the LED shows red for more than 10 hours, the anode is
faulty and a service engineer must be called.
