60 °C.
There is a risk of scalding at outlet temperatures in excess of 43 °C.
WARNING Burns
The water in the appliance can be heated to temperatures in excess of 60 °C.
- Install either a tempering valve or thermostatic mixing valve in all systems intended for personal hygiene. With this the delivery temperature for per-sonal hygiene outlets must be limited to 50 °C.
WARNING Injury
The appliance may be used by children aged 3 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.
WARNING
For continued safety of this appliance it must be in-stalled, operated and
maintained in accordance with the manufacturer’s instructions.
WARNING
This appliance may deliver water at high temperature. Refer to the plumbing
code of Australia (PCA), local requirements and installation instructions to
determine if additional delivery temperature control is required.
Material losses
The user should protect the appliance, the water pipes, the safety valve and
the tap against frost.
Material losses
If the drain pipe of the safety valve is sealed, expanding water can lead to
water damage.
Test symbols
See type plate on the appliance.
Appliance description
The appliance constantly keeps the water content available at the preset
temperature. The appliance switches on automatically as soon as its
temperature falls below the set value.
Subject to season, varying cold water temperatures can result in different
maximum mixed water and outlet volumes.
Note
The appliance is under mains water pressure. The water volume increases as the
cylinder is being heated up. Dur-ing this process, expansion water drips
through the safety valve. This is a necessary and normal process.
Cleaning, care and maintenance
- Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.
- Check the taps regularly. Limescale deposits at the tap out-lets can be removed using commercially available descaling agents.
- Regularly activate the safety valve to prevent it from becoming blocked, e.g. by limescale deposits.
- Have the protective anode checked by a qualified contractor after the first 2 years of operation. The qualified contractor will then determine the intervals at which it must be checked thereafter.
Almost every type of water will deposit limescale at high temper-atures. This settles inside the appliance and affects both the per-formance and service life. The heating element 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.
Troubleshooting
If you cannot remedy the fault, notify your qualified contractor.
To facilitate and speed up your enquiry, please provide the serial number from
the type plate. (000000):
