2. Safety
2.1 Intended use
This open vented (non-pressurised) appliance is designed for heat-
ing domestic hot water. The appliance can supply one draw-off
point.
This appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in a non-do-
mestic environment, e.g. in a small business, as long as it is used
in the same way.
Any other use beyond that described shall be deemed inappropri-
ate. Observation of these instructions and of instructions for any
accessories used is also part of the correct use of this appliance.
2.2 General safety instructions
WARNING Burns
There is a risk of scalding at outlet temperatures in ex-
cess of 43 °C.
!
WARNING Injury
The temperature selector should only be removed by a
qualified contractor.
!
WARNING Injury
The appliance may be used by children aged3 and older
and persons with reduced physical, sensory or mental
capabilities or a lack of experience and know-how, pro-
vided that they are supervised or they have been in-
structed on how to use the appliance safely and have
understood the resulting risks. Children aged 3 to 8 years
are only allowed to operate the tap connected to the
appliance. Children must never play with the appliance.
Children must never clean the appliance or perform user
maintenance unless they are supervised.
Where children or persons with limited physical, sensory or men-
tal abilities are allowed to use this appliance, we recommend a
permanent temperature limit. A qualified contractor can set this
limit.
!
Material losses
The user should protect the appliance and its tap against
frost.
!
Material losses
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.
!
Material losses
Connecting the appliance via a time switch will cause an
unintentional reset of the high limit safety cut-out.
f Never connect the appliance to the power supply via
a time switch.
2.3 Test symbols
See type plate on the appliance.
3. Appliance description
The open vented (non-pressurised) appliance constantly maintains
the water content at the pre-selected temperature. The appliance
may only be installed with taps for open vented (non-pressurised)
water heaters (see chapter "Installation/ Appliance description/
Accessories").
thermostop function
The thermostop function (thermal separation) prevents the tap
becoming hot in standby mode.
Anti-drip function
The anti-drip function prevents expansion water from escaping
from the tap during heating. When water is heated, gas bubbles
are formed. The amount of gas bubbles depends on the water
quality. At temperatures >75°C the rising gas bubbles can cause
residual water to drip from the tap outlet.
Subject to design, some taps have a tendency to drip for a short
while after being closed. This dripping is caused by residual water
escaping from the tap outlet and is not linked to expansion water.
