Notes for the operator

10.1.8 Replacement of the potable water fi lter
insert
During maintenance, also consider the potable water fi lter
installed in the cold water inlet of the station.
f
Replace the fi lter insert annually with a new one (item
no. 6125101).
11. Notes for the operator
Have the specialist tradespeople instruct you in
the safe and intended use of the station and the
necessary maintenance work!
f
Carry out a visual inspection at least once a month.
When doing so, pay attention to whether moisture is
leaking. In case of water leakage, inform the responsible
installation company.
f
Trigger the station safety valve (position
page 11) once every six months.
To do this, turn the plastic cap of the valve
anticlockwise until a "click" sound is clearly audible.
General notes on setting the potable water tem-
perature
The controller is preset to a potable water tem-
perature of 60 °C. In principle, however, you have
the option of increasing the potable water tem-
perature at the draw-off points via the controller.
Since this temperature is detected by a sensor at
the hot water outlet of the heat exchanger, it is
not the same as the hot water temperatures at
the draw-off points.
If you want to increase the water temperature at
the draw-off points, you can increase the potable
water setpoint temperature via the "+" key (e.g. in
5 °C steps).
Increasing the hot water temperature always
means increasing the energy consumption and
decreasing the hot water temperature always
means saving energy.
56
Risk of scalding due to excessively hot potable
water at the draw off points!
Due to setting or defect of the controller, the hot
water temperature at the draw-off points can rise
up to the heating water temperature in the buffer
storage cylinder.

CAUTION
If there is a risk of scalding in accordance with
DIN EN 806 and DIN 1988 due to high heating
water temperature in the buffer storage
cylinder, you must install scald protections at all
draw-off points.
If you do not use scald protections at all draw-
off points, regulate the temperature of the
storage cylinder circuit down to such an extent
that the temperature in the storage cylinder
and thus the potable water temperature cannot
cause any risk of scalding.
Legionella prevention
Legionella multiply particularly quickly if the hot
water temperature is constantly too low or if the
water is left standing for a long time(> 72 h) with-
out being tapped.
f
Tap water regularly to ensure regular potable water
replacement and to prevent prolonged periods of
standing potable water.
f
After each standing period of 72 h or more, run
the water at all draw-off points for a short time to
replace the potable water in the pipes.
f
When using a circulation pipe, the hot water tem-
perature must be at least 60 °C.
