5.7 First Commissioning
The tank must be filled with water before switching on the electricity.
The expansion water created in the internal boiler during the heating process must drip from the safety valve in the case of a
pressure-proof connection, and from the overflow mixing tap in the case of an unpressurised connection.
Caution: the hot water drain pipe as well as parts of the safety fitting may become hot.
The preset temperature, the actual temperature of the water withdrawn and the hot water quantity display should correspond
approximately after completion of the heating process.
6. Inspection, Maintenance, Service
The boiler scale as well as the furring that forms in the internal boiler of the storage tank in the case of heavily calciferous
water must be removed by an expert after one to two years of operation. The cleaning is performed through the flange
opening – de-install the built-in heater, clean the storage tank, use a new seal when mounting the heating flange.
The internal tank of the water heater with special enamelling must not get in contact with boiler scale solvents – do not
use an antiliming pump.
Finally, the device must be rinsed thoroughly and the heating process be observed in the same way as during the first
commissioning.
In order to be entitled to any claims for warranty, as provided on the part of AE AG, the installed reactive anode requires
documented inspection by an expert in intervals of maximum 2 years of operation. Practically, the external current anode
has an unlimited service life. Its function must be monitored regularly by means of the control lamp. This indicates two
operating conditions:
Green: system ok
Red, flashing: malfunction - call customer service!
Pre-requisite for flawless functioning is that the tank is filled with water. For proper functioning of the external current anode,
a conductivity of the medium of >150 µs/cm is required.
The guard circuit shunt resistor must not be damaged or removed during maintenance works.
Do not use any abrasive cleaning agents and paint thinners (such as nitro, trichlor etc.) to clean the device.
The best cleaning method is to use a damp cloth added with a few drops of a liquid household cleaner.
During servicing works, it is advisable to open the cleaning and servicing flange in order to inspect the tank for any foreign
objects that may have been washed in as well as any contamination, and to remove any such, if applicable.
7. Malfunctions
If the tank water is not heated, please check whether the line circuit breaker (automatic safety cutout) or the safety fuse in
the distribution box have reacted, and check the setting of the temperature control.
In all other cases, do not attempt to rectify the fault yourself. Please contact either a licensed plumber or our customer ser-
vice. In many cases, experts only need to do a few little jobs and the storage tank works again. During notification, please
quote your model designation and manufacturing number, which you can find on the rating plate of your built-in heater.
