For users and contractors
Thank you for purchasing this instantaneous water heater from AEG Haustechnik. You have chosen a
high-grade device made in Germany.
Even during the development and manufacture, AEG Haustechnik recognises the high value of manufacturing
processes that are environmentally responsible and treat resources with care. Thanks to many product
innovations, devices made by AEG Haustechnik are amongst the most energy-efficient in their class.
1.
Operating instructions
1.1
Equipment description
The instantaneous water heater DDLE Basis heats water as it flows through the equipment. You can adjust
the DHW outlet temperature anywhere between approx. 30 °C and approx. 60 °C via a temperature selector.
From a flow rate of approx. 3 l/min onwards, the control regulates the correct heating output, subject to the
temperature selection and the cold water temperature.
1.2
Vital facts in brief
s4EMPERATURESELECTOR
Turning the selector lets you freely choose the required temperature.
Wash basin ( 35 °C )
Shower ( 40 °C)
Bath ( 45 °C )
Sink ( 55 °C )
Should the outlet temperature fail to reach the required level, when the tap is fully opened, and the
temperature selector has been set to maximum (temperature selector turned fully clockwise), then more water
flows through the equipment than can be heated by the internal heater cartridge (output limit 11;13,5; 18;
21; 24 or 27 kW). In such cases, reduce the flow rate at the tap accordingly.
s4EMPERATURELIMIT
A contractor can set the temperature limit to 43 °C at the device. You can still adjust the temperature selector
across its entire range. The outlet temperature will be permanently limited to 43 °C.
A temperature range 30 °C to 43 °C can be selected.

Where children or persons with limited physical, sensory or mental capabilities are to be allowed to control
this equipment ensure that this will only happen under supervision or after appropriate instructions by a
person responsible for their safety. Children should be supervised to ensure that they do not play with the
equipment - risk of scalding.

Recommended settings when using a thermostatic valve
To safeguard the function of the thermostatic valves, set the instantaneous water heater to its maximum
temperature (temperature selector to the right end stop).
1.7
First aid in case of faults
s Check all fuses.
s Check taps/valves and shower heads for scaling or contamination (see also "6. Troubleshooting").
Where a contractor is required, he can better and more speedily remedy the fault if you provide him with
some of the details from the type plate ( A 20):

Undersink installation, water connections from the top
Undersink installation with water connections from the top can be achieved with the additional pipe assembly
for undersink devices (part no. 18 44 21). Cleanly break out the water pipe knock-outs in the back panel and
fit the pipe set.
If the maximum temperature is to be limited to 43 °C, this is done on the inside of the
device cap. For this, replug the temperature selector cable in the device cap from 60 °C
to 43 °C. You can still adjust the temperature selector across its entire range. The outlet
temperature will be permanently limited to 43 °C. A temperature range 30 °C to 43 °C
can be selected.
