Product descrIPtIon
AIC’s SILOX water heaters are twin-wall cylinders
that are designed for the production and storage of
Domestic Hot Water. They consist of a steel outer
tank (primary) and a built-in stainless steel DHW
tank. At each draw-o of DHW and heating cycle,
the inner tank expands and contracts, which pre-
vents the adhesion and build-up of sediments.

They can also be equipped with an optional elec-
tric heating element, whose power varies accord-
ing to the model. Larger models equipped with an
optional heating element can operate on Tri-phase
electrical power. Please contact your AIC repre-
sentative to know which immersion heaters are

Technical SpecificaTionS
Recommendations for the Quality of Water
To prevent the formation of scale and sludge in a
closed heating circuit through the penetration of
oxygen and carbonates, follow the recommenda-
tions below:
îBefore  lling the system, clean it according to
standard EN14336. Chemical cleaning agents
can be used.
îIf the circuit is in bad condition, or the cleaning
operation was not e cient, or there is a large
volume of water in the system (e.g. cascade),
it is recommended to separate the appliance
from the heating circuit using a plate heat ex-
changer or an equivalent accessory. In that
case, it is recommended to install a hydrocy-
clone or magnetic  lter on the system side.
îLimit the  ll operations. To control the quantity
of water added into the system, install a water
meter on the  lling line of the primary circuit.
No more than 5% of the total content of the
system is allowed annually.
îAutomatic  lling systems are not recom-
mended unless the  ll frequency is checked
and the levels of scale and corrosion inhibitor
are maintained at an appropriate level.
îIf the system needs to be re lled frequently,
check for leaks in the primary circuit.
îInhibitors may be used according to stand-
ard EN 14868.
îAn air separator (on the appliance supply
circuit) combined with a dirt separator (up-
stream of the appliance) must be installed
according to the manufacturer’s instructions.
îAdditives can be used to keep the oxygen in
solution in the water.
îUse the additives in accordance with the in-
structions of the manufacturer of the water
treatment product.
Water Hardness
îIf the hardness of the  ll water is higher than
20° fH (11,2° dH), soften it. At commission-
ing, the water should be soft.
îCheck regularly the water hardness and en-
ter the values in the maintenance log sheet
(provided at the end of the manual).
Water Parameters
îIn addition to the oxygen and the water hard-
ness, other parameters of the water must be
checked. Treat the water if the measured val-
ues are outside the range of the table below.
îAIC recommends to have the DHW circuit
operating at more than 60°C to prevent the
development of bacteria in the DHW circuit.
Water Parameters Range
Acidity 8.2 < pH < 9.0
Conductivity < 400 μS/cm (at 25°C)
