off and flush through cold, fill the central heating system
again, add a flushing detergent, we highly recommend the
use of a flushing detergent appropriate for the metals used in
the aluminium alloy circuit. These include (Fernox Superfloc,
BetzDearborn Sentinel X300 or X400), whose function is to
dissolve any foreign matter that may be in the system, and
run the boiler on central heating until it reaches its operating
temperature, flush the system as instr ucted by the
manufacturer of the flushing detergent and refill the system
with a suitable corrosion inhibitor such as Fernox Copal MB-
1, or BetzDeaborn Sentinel X100 is recommended.

.
In hard water areas or where large quantities of water are in
the system the treatment of the water to prevent premature
scaling of the main heat exchanger is necessary.
The formation of scale strongly compromises the efficiency of
the thermic exchange because small areas of scale cause a
high increase of the temperature of the metallic walls and
therefore add to the thermal stress of the heat exchanger.
Demineralised water is more aggressive so in this situation it
is necessary to treat the water with an appropriate corrosion
inhibitor.
- Any treatment of water by additives in the system for frost
protection or for corrosion inhibition has to be absolutely
suitable for all the metals used in the circuit including the
aluminium alloys.
- If anti-freeze substances are to be used in the system, check
carefully that they are compatible with the aluminium.
In particular, DO NOT USE ordinary ETHYLENE GLYCOL,
since it is corrosive in relation to aluminium and its alloy, as
well as being toxic.
MTS suggests the use of suitable anti-freeze products such
as Fernox ALPHI 11, which will prevent rust and incrustation
taking place.
Periodically check the pH of the water/anti-freeze mixture of
the boiler circuit and replace it when the amount measured is
out of the range stipulated by the manufacturer ( 7 < pH < 8).
DO 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 (metal
piping, boiler, etc), through the formation of oxides 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 exchanger
s of those
with a specific system water treatment.
IMPORTANT
Failure to carry out the water treatment procedure will
invalidate the appliance warranty
