Never subject the appliance to water pressure. The tap
outlet has a vent function. Scale build-up can block the
outlet and subject the appliance to pressure.
f Never seal the tap outlet.
f Only use special aerators for non-pressurised water
heaters.
f Never extend the tap outlet with a hose.

Appliance description
This open vented (non-pressurised) appliance constantly main-
tains 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 heaters (see chapter "Installation / Appliance description /
Accessories").
Subject to season, varying cold water temperatures can result in
different maximum amounts of mixed outlet water.
Thermostop function
The thermostop function (thermal separation) of the
ESH 10 U-N Trend prevents the tap becoming hot in standby mode.
3.1
Operation
You can set any required DHW outlet temperature variably at the
temperature selector. The heat-up indicator illuminates during
the heat-up process.

Cleaning, care and maintenance
f Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
f Check the tap regularly. You can remove limescale depos-
its at the tap outlet using commercially available descaling
agents.
Almost every type of water will deposit limescale at high temper-
atures. This settles inside the appliance and affects both perfor-
mance and service life. The heating elements should therefore be
descaled if necessary. A qualified contractor who is aware of the
local water quality will tell you when the next descaling is due.
