Maintenance
9.2 Leakage test (visual inspection)
Due to the temperature fluctuations caused by operation,
we recommend that you check the screw connections and
seals annually for correct functioning.
1
Check all connections to the outside of the pipework
and inside the station for moisture.
2
If necessary, tighten loosened screw connections and
replace defective seals.
Moisture associated with discolouration on the heat
exchanger indicates external corrosion that necessitates
replacement.
3
Check the heat exchanger for moisture and
discolouration and replace a defective heat exchanger
immediately.

components and plug-in

Check the plug-in connections annually for correct seating.
f
Check the electrical components (1, 2, 3, 4, 5) connected
to the station for integrity and firm seating.
f
Check the cable plug-in connections of all components
connected to the actuator (7).
f
Check the tight screw connection of the actuator (7) on
the control valve (6).
9.4 Performance test of the heat
exchanger
To exclude calcification and contamination of the heat
exchanger, we recommend that you check the
performance of the heat exchanger annually.
1
Tap hot water at several draw-off points at the same
time without adding cold water.
2
Measure the hot water temperature at the draw-off
point furthest away from the station.
3
Compare the measured hot water temperature with
the hot water temperature set at the actuator.
The performance of the heat exchanger is correct if the
measured hot water temperature is not more than 5 °C
higher or lower than the hot water temperature set at the
actuator (e.g. 60 °C).
If the deviation is more than 5 °C:
f
Check the filter insert.
f
Check the flow temperature.
f
Check the volume flow sensor in the supply
respectively the differential pressure.
f
Clean and decalcify the heating exchanger as described
in paragraph 8.3 on page 39.
