7.3 Water treatment
> The water connection must not use treated
water with hardness below 6°e, as such water
is aggressive and corrosive, and can shorten
the lifespan of the device.
> Connecting the SCC to water with hardness
below 8,75°e:
When the self-test begins, the system will
prompt the user to indicate the hardness of
the water the device is connected to. Select
“Water hardness below 8,75°e.
> Observe all country-specific regulations
regarding water and sewer connections, espe-
cially those regarding installation of water
intake points.
In most cases, water connections do not require
additional filters or water treatment.
Filtration and/or water treatment (A, B, C, D)
may be necessary if water conditions are critical.
Contact the local water supply company to
inquire about water chloride levels (Cl
–
), chlorine
levels (Cl
2
) and hardness.
7.4 Selectingwaterlters
A) Fine filters We recommend fine filters with fineness of 5 -
15µm for filtering water contaminated with sand,
iron particles or suspended matter.
B) Active carbon filters If water contains high levels of Cl
2
(over 0.2mg/l,
corresponds to 0.2ppm) (information provided
by water supply company), an upstream active
carbon filter must be installed.
C) Reverse osmosis system Due to corrosion risks, a reverse osmosis system
must be used if and only if chloride (Cl
–
) con-
centrations are above 80mg/l (corresponds to
80ppm, information provided by water supply
company).
Note: Ensure that the minimum conductivity
value of 50µS/cm (Micro Siemens) is being
maintained.
