D
O NOT MIX DIFFERENT TYPES OF ANTI-FREEZE
- In under-floor systems, the use of plastic pipes without
protection against penetration of oxygen through the
walls can cause corrosion of the system’s metal parts (
m
etal piping, boiler, etc), through the formation of
o
xides and bacterial agents.
To prevent this problem, it is necessary to use pipes
with an “oxygen-proof barrier”, in accordance with
standards DIN 4726/4729
. If pipes of this kind are
not used, keep the system separate by installing
heat exchangers of those with a specific system
water treatment.
IMPORTANT
Failure to carry out the water treatment procedure will
invalidate the appliance warranty.
