1.6 CYCLOIDAL FILTER UNIT.
The magnetic cycloidal filter is standard supplied in the boiler.
Allows to detect the ferrous residues present in the system's water.
Thanks to the two cocks it facilitates maintenance by cleaning the
filter without having to empty the circuit.
Install the cycloidal filter on the system return connection using
the pipes as shown in the figures below (Fig. 6).
Cleaning the filter.
- Disconnect the boiler from the power supply, close the cock
upstream of the filter, partially discharge the hydraulic circuit
pressure and then close the second shut-off cock.
ATTENTION:
check that the temperature of the system
return water is not too hot otherwise
take precautions to avoid burns.
- Place a container under the filter to collect the water contained
in it.
- Remove the clip and pull out the magnetic cartridge by pulling
it downwards.
- Clean the cartridge with a clean cloth and under running water.
- Put the magnetic cartridge back in place, making sure that the
centring pins match and that the sealing O-ring is not damaged.
If necessary, replace it with a new one.
- Lock the magnetic cartridge in place with the clip.
- Open the two shut-off cocks and restore power to the boiler to
bring it back to normal operating conditions; at the same time
check the operating pressure of the appliance and, if necessary,
restore it to a correct value.
