2. Close the drain valves on the domestic water circuit by turning the
Allen key a quarter turn.
3. Open the bleed screws.
4. Await the complete drainage of the water circuit.
This may be a long operation. To reduce the waiting time, keep the
safety valve open.
5. When no more water flows out, close the bleed screws and the drain
valves.
10.5 Clean the magnetic sieve filters
The magnetic filters on the heating circuit return and the second heating
circuit return (if present) prevent the plate heat exchanger from becoming
clogged.
The magnetic filters must be cleaned every year to ensure that water is
able to flow correctly within the installation.
10.5.1 Magnetic filter annual maintenance
1. Switch off the appliance and close the valves for the heating circuits
on the plate.
2. Remove the magnet from the filter.
The magnetic particles stuck inside the filter will drop to the bottom
and be ejected via the vent.
3. Connect a pipe to the filter valve, then open the valve by a quarter
turn.
