Appliance description

The open vented (non-pressurised) appliance constantly maintains
the water content at the pre-selected temperature. During heating,
expansion water drips from the tap. The appliance may only be
installed with taps for open vented (non-pressurised) water heat-
ers (see chapter "Installation / Appliance description / Required
accessories").
thermostop function
The thermostop function (thermal separation) prevents the tap
becoming hot in standby mode.
3.1 Operation

Cleaning, care and maintenance

f Never use abrasive or corrosive cleaning agents. A damp f
cloth is sufficient for cleaning the appliance.
f Check the tap regularly. You can remove limescale deposits f
at the outlet using commercially available descaling agents.
Almost every type of water will deposit lime at high temperatures.
This settles inside the appliance and affects both the performance
and service life. The heating elements should therefore be des-
caled if necessary. A qualified contractor who is aware of the
local water quality will tell you when the appliance should next
be descaled.
