8.3 Corrosion protection anode

The corrosion protection anode (Fig.8.1) installed in the domestic
hot water cylinder should be electrically checked on a regular ba-
sis, at least every two years after commissioning, and be re-
placed if necessary. The electrical inspection is carried out using
a suitable ammeter, without draining the cylinder.
Procedure:
1) Remove the front panelling
2) Unplug the PE cable from the protection anode tab.
3) Connect the ammeter (0 to 50 mA) between the PE cable
and the tab.
4) Assessment of the protection anode wear:
Measured value > 1 mA  protection anode OK.
Measured value < 1 mA  protection anode must be
checked 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).
NOTE
Malfunctioning protection anodes reduce the service life of the device!
(Sacrificial anode: Electrically insulated magnesium anode with selenium
according to DIN 4753 part 6)

9 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!
Please check whether
 the plug is plugged in
 the operating switch (on the keypad) has been pressed
 the socket is supplied with voltage
 the air intake / ambient temperature is
30HS /
 the domestic hot water temperature has already reached (or
exceeds) 60 °C
The heat pump switches off prematurely (set
temperature has not yet been reached)
Please check whether
 air ducts have been bent or their openings have been
sealed, or whether any air filters are heavily contaminated
(clogged).
Condensate cannot drain properly (there is water
under the device)
Please check whether
 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 inflow and outflow of air is significantly reduced (bent air
duct / clogged air filter).
If the above questions cannot help you eliminate these faults,
please contact your technician or after-sales service partner.

10 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.
11 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 accordance with DIN EN 378.
