12.3 Connecting to a water filter (required in hard
water areas)
!
Property damage
The UltraHot Plus/Premium appliance must be operated
with a water filter when water hardness values are great-
er than or equal to 8.76 gpg (1.5 mmol/l). This will prevent
limescale buildup in the appliance. Using the appliance
without an external water filter at values above these will
void the appliance warranty. Damage to the appliance
caused by limescale or a high mineral concentration is
not covered by the warranty.
In areas with hard water, when water hardness values are greater
than or equal to 8.76 gpg (1.5 mmol/l), the UltraHot Plus/Premium
appliance must be operated with a water filter (not supplied). For
the water filter to work properly, it should be installed between
the wall connection and the faucet.
Note
Follow the filter manufacturer‘s operating and instal-
lation instructions when installing the water filter (not
supplied).
