2. Safety
2.1 Intended use
This open vented (non-pressurised) appliance is designed for heat­ing 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-do­mestic 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 inappropri­ate. 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 ex­cess 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 aged 8 and up and persons with reduced physical, sensory or mental capa­bilities or a lack of experience and know-how, provided that they are supervised or they have been instructed on how to use the appliance safely and have understood the resulting risks. 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 men­tal abilities are allowed to use this appliance, we recommend a permanent temperature limit. A qualified contractor can set the limit.
Material losses
!
Protect the appliance and its tap against frost.

OPERATION
ENGLISH
Appliance description
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.
Never seal the tap outlet.Only use special aerators for non-pressurised water
heaters.
Never use a hose with aerator to extend the tap
outlet.
Material losses
!
Connecting the appliance via a time switch will cause an unintentional reset of the high limit safety cut-out.
Never connect the appliance to the power supply via
a time switch.
2.3 CE designation
The CE designation shows that the appliance meets all essential requirements according to the:
- Low Voltage Directive
- Electromagnetic Compatibility Directive
2.4 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.
3.1 Operation
The required DHW outlet temperature can be set at the tempera­ture selector. The heat-up indicator illuminates during the heat-up process.

°C = Cold. On this setting, the appliance is protected from
frost. The tap and the water line are not protected.

85 = Maximum selectable temperature
Note
A qualified contractor can set a temperature limit on the appliance (see chapter "Installation/ Settings/ Setting the temperature limit").
4. Cleaning, care and maintenance
Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
Check the tap regularly. You can remove limescale deposits
at the outlet using commercially available descaling agents.
5. Troubleshooting
Problem Cause Remedy
The appliance does not supply hot water.
Water can only be drawn at a reduced rate.
Loud boiling noises in­side the appliance.
Water drips from the tap outlet during the heat-up process.
If you cannot remedy the fault, notify your qualified contractor. To facilitate and speed up your request, provide the number from the type plate (000000-0000-000000).
