13. Check, Maintenance, Care
a) During heating, the expansion water must drip visibly from the drain of the safety valve (the expan-
sion water drips from the valve of the mixing tap in the case of an unpressurised connection). The
expansion water quantity is approx. 3.5% of the tank's rated volume when fully heated (~ 85° C).
The function of the safety valve must be checked regularly. When the safety valve test knob is
lifted or turned to the position »Test«, the water must flow freely from the safety valve unit into the
drain funnel.
Caution: thereby, the cold water supply and parts of the storage tank connector fittings may
become hot.
If the water heater is not heated up or hot water is withdrawn, then no water must drip from the
safety valve. If this is the case, then either the water line pressure is too high or the safety valve is
defect. If the water line pressure exceeds 6 bar, then a pressure reducing valve must be installed.
Please call a plumber immediately, of whom it is recommended that he should also perform an
annual check of the system.
b) The boiler scale as well as the furring that forms in the internal boiler of the tank must be remo-
ved by an expert after one to two years of operation in the case of heavily calciferous water.
The cleaning is performed through the flange opening after emptying: de-install heating flange,
clean the tank; a new seal must be used when the flange is mounted. 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 monitored in the same
way as during the first commissioning.
c) In order to be entitled to any claims for warranty, as provided on the side of AE AG, the installed
reactive anode requires checking by an expert in intervals of max. 2 years of operation. External
current anodes that may be installed are maintenance-free; check control lamp occasionally.
Check the mains connection and the anode plug-in termination as well as the ground connection
in the event of any malfunction. Do not switch off the external current anode during periods of
standstill, unless the boiler was emptied.
d) 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.
This device is not designed to be used by persons (including children) with physical, sensory or
mental disabilities or lacking experience and/or lacking knowledge, unless these are supervised by
a person who is responsible for their safety or have received instructions on how to use this device
from any such person. Children should be supervised in order to ensure that they do not play with
this device.
