Drinking Water Connection; Warm Water Heater Battery Connection - Helios HygroBox KWL Series Installation And Operating Instructions Manual

16.3 Drinking water connection

Only drinking water that corresponds with the drinking water ordinance may be used for the water supply.
Only the original connecting hoses provided in delivery may be used for the connection to the water supply.
The operating pressure of a minimum of 0.35 MPa and a maximum of 0.7 MPa and a water temperature of a
minimum of 8°C and a maximum of 30°C may not be undershot or exceeded, respectively.
In case of a chlorine content over 0.1 mg/l, the standard water filter (5 μm) must be replaced by a dual filter (5
μm/carbon) (optionally available as an accessory). If the iron content of the drinking water exceeds a value of 0.1 mg/l,
an iron filter should also be built into the water inlet pipe upstream of the fine filter. The device can be used for a
maximum water hardness of 26°dH.
If this value is exceeded, the service life of the reverse osmosis membrane is considerably reduced!
