3. 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 / Ap-
pliance 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 5 U-N Trend prevents the tap becoming hot in standby mode.

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 depos- f
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.
