2.5 Maintenance

1. Remove the insulation shells and check the system for leaks.
2. Check the function of the automatic air vent.
a.) Reduce the system pressure of the boiler guard until the automatic air vent draws air. This air will escape again when filling.
b.) Loosen the screw connection to the automatic air vent under system pressure. With an intact automatic air vent, water will escape
from this leak point without air escaping first.
3. Stop water from flowing through the boiler guard (close the shut-offs and switch off the pumps). Pull the stack of magnets out of the
brass case of the magnetite separator – the accumulated magnetic foreign particles will sink to the base of the tank. Hold a bucket or
similar under the fill and drain ball valve at the base of the boiler guard and open it fully – the foreign particles will be flushed out.
4. Check the system pressure.
