Please note
Unsuitable fill water increases
the level of deposits and corro-
sion and may lead to boiler dam-
age.
■ Flush the heating system thor-
oughly before filling.
■ Only use fill water of potable
quality.
■ An antifreeze additive suitable
for heating systems can be
added to the fill water. The anti-
freeze manufacturer must ver-
ify its suitability.
■ Fill and top-up water with a
water hardness in excess of
the following values must be
softened, e.g. with a small soft-
ening system for heating water.
