Make sure that the percentage of antifreeze liquid in the mixture is below the
freezing point; it can be added.
Make sure that the pH of the water and antifreeze liquid mixture exceeds
8. In the event this value is lower, add a corrosion inhibitor (However, the
antifreeze liquid must be replaced every 3-4 years).
Check that the pressure of the collector circuit has dropped below the mini-
mum pressure of the system (15 bar + hydrostatic gradient), and finally inte-
grate the cold system with the mixture of water and antifreeze liquid.
Check the operation of the automatic air bleed valve; remove the cap and
press using a screwdriver. If air is released together with the liquids, the
automatic valve is not working properly. Replace the valve if required.
Empty the collector circuit and wash using running water.
Pour the mixture of antifreeze liquid and water in the proportion suitable
for the new antifreeze.
Check the magnesium anodes and replace if worn.
Drain the hot water contained in the boiler and remove the anode to check
the state of wear.
