INSTALLATION
Cleaning, care and maintenance
Depending upon the system, the actual water temperatures at the
tapping points may be lower than the set value.
WARNING Burns
There is a risk of scalding at outlet temperatures in
excess of 109 °F (43 °C).
Setting the temperature above 125 °F (52 °C) is not rec-
ommended without the installation of a mixing valve.
ON/OFF indicator
The ON/OFF indicator illuminates when water is being heated.
5.1 Vacation and absence
f
If the appliance will not be used for a few days, set the tem-
perature knob to a position between the frost protection and
energy saving settings.
f
If the appliance is not to be used for a longer period, set it to
frost protection to conserve energy. If there is no risk of frost
you may disconnect the appliance from the power supply.
f
To protect against Legionella, heat the water once 140 °F
(60 °C) before using hot water again.
6. Cleaning, care and maintenance
f Have the electrical safety of the appliance and the func-
tion of the T&P relief valve regularly checked by a qualified
technician.
f
Have the sacrificial anode initially checked by a qualified
technician after the first year. The qualified technician should
then determine the intervals at which it must be checked
thereafter.
f Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the exterior of the appliance.
Scaling
f
Almost every type of water will deposit lime at high tem-
peratures. This settles inside the appliance and affects both
the performance and service life. The heating elements must
therefore be descaled from time to time. A qualified tech-
nician who knows the local water quality will tell you when
the next service is due. Contact the water supplier or local
plumbing inspector for additional information.
f
Check the taps/faucets regularly. You can remove lime scale
deposits at the outlets using commercially available descal-
ing agents.
f
Regularly activate the T&P relief valve to prevent it from be-
coming blocked e.g. by lime scale deposits.
7. Troubleshooting
Problem Cause Remedy
The water does not heat
up and the ON/OFF indi-
cator does not illuminate. There is no power.
Check the fuses/circuit
breakers in your fuse
box.
The water does not heat
up sufficiently and the
ON/OFF indicator is illu-
minated.
The temperature is set
too low. Select a higher tempera-
ture.
The appliance is heating,
for example, after large
amounts of DHW have
been drawn. Wait until the ON/OFF
indicator goes out.
The flow rate is low.
The aerator in the tap or
shower head is scaled up
or contaminated. Clean and/or descale the
aerator or shower head.
If you cannot remedy the fault, notify your qualified technician. To
facilitate and speed up your inquiry, please provide the numbers
from the type plate (000000 and 0000-000000):
