14. Inspection, Maintenance, Care
a) During the heating-up process, the expansion water must be seen to drip from the outlet of the sa-
fety valve. When the unit is fully heated-up (approx. 80°C) the expansion water totals approximately
3.5% of the contents of the storage tank.
The functioning of the safety valves should be inspected every month. When raising or rotating the
safety valve checking nob into the“Prüfen“ („Test“) setting, the water must flow unimpeded out of the
body of the safety valve into the overflow funnel.
Warning: The cold water intake and parts of the storage unit connection fittings can become hot
during this process.
Should be hot water heater not be heated up or hot water not be removed, no water may drip from
the safety valve. It this should be the case, either the pressure in the water line is too high (install
more than 5.5 bar pressure reduction valve) or the safety valve is faulty. Please immediately call the
installation specialist.
b) In the event of highly calcified water the removal by a specialist of lime-scale build-up in the inside
of the storage unit boiler and of any freely detached lime-scale particles after one to two years of
operation may be necessary.
The cleaning process is carried out through the flange opening - remove the heating flange, clean
the storage unit and when re-assembling the heating flange, a new seal should be utilised. The spe-
cially enamelled internal container of the hot water heater may not come into contact with lime-scale
dissolving substances - do not use a lime-de-scaling pump.
The equipment is finally to be fully rinsed out and the heating-up procedure is to be observed as per
the initial commissioning.
c)
To be entitled to make claims under the warranty that is offered by Austria Email, the built-in
protective anode is required to be inspected by the qualified specialist within a maximum
period of every 3 years.
The protective discharge current resistor underneath the heater body
fixing screw should not be damaged or removed during maintenance work.
d) No abrasive cleaning material or any paint thinners (such as Nitro, Trichlor, etc.) may be used for
cleaning the apparatus. The best thing to use for cleaning is a damp cloth to which a couple of
drops of liquid household cleaner have been applied. In hospitals and other public buildings, the
prevailing regulations for cleaning and disinfection must be observed.
When carrying out service work it is advisable to also open the cleaning and service flange, in order to
inspect the storage tank for possible infestations and contamination and to remove these if need be.
15. Functional breakdowns
If the water storage unit is not fully heated-up please check whether the circuit breaker(disconnect
switching device) or the safety fuse has tripped and check the setting of the temperature control unit.
In all other cases do not try to rectify the fault yourself. Please get in touch either with an approved ins-
taller or with our customer service department. When making use of qualified specialists it is often only
a small amount of manual work and the storage unit is back in running order. Please ensure that you
give to the responsible persons the model designation and the serial number, which you will find on the
rating plate of your electric storage unit.
