7.3 Corrosion protection anode
The corrosion protection anode installed in the domestic hot
water cylinder should be electrically checked on a regular basis
(at least every two years after commissioning) and be replaced
as necessary. Electrical checking is carried out by means of a
suitable ammeter, without draining the cylinder.
Procedure:
1) Unplug the PE cable from the protection anode tab.
2) Connect the ammeter (0 to 50 mA) between the PE cable
and the tab.
3) Evaluation of wear on the protection anode:
Measured value > 1 mA

protection anode is in working
order.
Measured value < 1 mA

protection anode must be tested
and/or replaced.
If electrical testing does not provide any clear results, a visual in-
spection of the protection anode by a technician is recom-
mended.
Should replacement of the protection anode [by a technician] be
necessary, the cylinder must be drained via the drainage valve
provided (to be fitted during installation - see Appendix).
ATTENTION!
Malfunctioning protection anodes reduce the service life of the device!
(Electrically insulated magnesium anode with selenium complying with
DIN 4753 part 6)
8 Faults / troubleshooting
(for the user)
ATTENTION!
Work on the domestic hot water heat pump is to be performed by
qualified personnel only!
Observe accident prevention regulations!
The heat pump will not operate!
Check the following:
 Voltage is applied to the device
 the intake air or ambient temperature is

0 °C
 The heat pump has not been switched off by the tempera-
ture controller
 the hot water temperature has reached (or exceeds) 60 °C
Condensate cannot drain properly (there is water
under the device)
Check the following:
 The seal valve in the end of the condensate hose is contam-
inated or clogged, and clean if necessary; the valve can be
easily removed and replaced.
 The air supply / air outlet is significantly reduced.
If the above suggestions cannot help you eliminate these faults,
please contact your technician or after-sales service partner.
9 Decommissioning
Tasks to be carried out:

Disconnect the domestic hot water heat pump from the
power supply.
 Completely shut off the water circuit (domestic hot water,
cold water and circulation pipe) and drain the domestic hot
water cylinder
through the drain valve.
10 Environmental
requirements
During maintenance or decommissioning of the domestic hot
water heat pump, all environmental requirements regarding re-
covery, recycling and disposal of materials and components
must be observed in compliance with DIN EN378.
