1) Nominal capacity in litres/heating output; in the case of multi-
boiler systems, the smallest single heating output is to be used.
Caution.
The use of unsuitable heating water may
cause aluminium corrosion and a result-
ing lack of leak-tightness.
In contrast to steel, grey cast iron or copper,
for example, aluminium reacts with alkaline
heating water (pH value > 8.5) to produce
substantial corrosion.
▶
When using aluminium, make sure that
the pH value of the heating water is
between 6.5 and a maximum of 8.5.
Caution.
Risk of material damage if the heating
water is treated with unsuitable additives.
Unsuitable additives may cause changes in
the components, noises in heating mode and
possibly subsequent damage.
▶
Do not use any unsuitable frost and cor-
rosion protection agents, biocides or seal-
ants.
No incompatibility with our products has been detected to
date with proper use of the following additives.
▶
When using additives, follow the manufacturer's instruc-
tions without exception.
We accept no liability for the compatibility of any additive or
its effectiveness in the rest of the heating system.
