1.2 Safety instructions for installation and operation
1.2.1 General
WARNING
Devices that have not been set up and installed correctly
can impair the function of the device and/or cause serious
or fatal injury to the user.
▪ Work on the device (e.g. set-up, inspection, connection
and initial commissioning) may only be carried out by
persons who are authorised and have successfully
completed qualifying technical or vocational training, enabling them to perform the respective activity and
who have participated in advanced training courses recognised by the relevant competent authority. These include, in particular, certified heating engineers, quali-
fied electricians and HVAC specialists, who, because
of their professional training and their expert know-
ledge, have experience in the professional installation
and maintenance of heating systems, gas installations
and hot water tanks.
▪ Before starting any work on the device, switch off the ex-
ternal main switch and secure it against unintentional
switch-on.
▪ Do not leave any tools or other objects below the hood
of the device after finishing installation or maintenance
work.
Avoiding danger
The hot water storage tank is state of the art and is built to meet all
recognised technical requirements. However, improper use may result in serious physical injuries or death as well as property damage.
To avoid danger, only install and operate the device:
▪ as stipulated and in perfect condition,
▪ with an awareness of safety and the dangers involved.
This assumes knowledge and use of the contents of these operating
instructions, of the relevant accident prevention regulations as well
as the recognised safety-related and occupational health rules.
Before working on the heating system
▪ Only authorised and trained heating technicians may work on the
hot water storage tank (such as installation, connection and initial
commissioning).
▪ Switch off the external main switch before starting any work on the
hot water storage tank and secure it against unintentional switchon.
▪ Seals must not be damaged or removed.
▪ Make sure that the safety valves comply with the requirements of
EN12828 when connecting on the heating side, and with the requirements of EN12897 when connecting on the domestic water
side.
▪ Only original replacement parts may be used.

1.2.2 Intended use
The device may only be used as a hot water storage tank. The
device must only be installed, connected and operated according to
the information in these operating instructions.
When connecting to an oil condensing boiler, only use the storage
tank connection kits provided for this purpose.
Only those electric immersion heaters supplied by the manufacturer
may be used.
Any other use outside the intended use is considered as improper.
The operator alone shall bear responsibility for any resulting damage.

1 General safety precautions
Intended use also includes compliance with the maintenance and inspection conditions. Replacement parts must at least satisfy the
technical requirements defined by the manufacturer. This is the
case, for example, with original spare parts.
1.2.3 Device installation room
For safe and fault-free operation, the installation location of the hot
water storage tank must fulfil certain criteria. Information on the installation location for the hot water storage tank can be found in
Chap. 4.1.
Information on the installation location of other components can be
found in the associated documentation supplied with them.
1.2.4 Electrical installation
▪ Before beginning work on live parts, disconnect them from the
power supply (switch off main switch, remove fuse) and secure
against unintentional restart.
▪ Electrical installations may only be carried out by qualified elec-
trical technicians under observance of the relevant electrical
guidelines and the regulations of the electric utilities company.
▪ For each hard-wired power connection, install a separate discon-
nector system compliant with EN60335-1 for all-pole disconnection from the power mains.
▪ Compare the mains voltage indicated on the nameplate with the
supply voltage before connecting to the mains.
1.2.5 Requirements for the filling water
Avoid damage caused by deposits and corrosion: Comply with the
applicable engineering regulations on the prevention of corrosion
products and deposits (VDI 2035, BDH/ZVSHK technical information
"Scale formation").
Measures for desalination, softening or hardness stabilisation are
necessary if the filling and top-up water have a high total hardness
(>3mmol/l - total of the calcium and magnesium concentrations, calculated as calcium carbonate).
Minimum requirements regarding the quality of filling and top-up water:
▪ Water hardness (calcium and magnesium, calculated as calcium
carbonate): ≤3mmol/l
▪ Conductivity: ≤1500 (ideal: ≤100) μS/cm
▪ Chloride: ≤250mg/l
▪ Sulphate: ≤250mg/l
▪ pH value (heating water): 6.5 - 8.5
Measures for desalination, softening or hardness stabilisation or
other suitable conditioning measures are necessary to maintain the
required water quality if the filling and top-up water have a high total
hardness or other properties divergent from the minimum requirements.
It is recommended to install the DRELECANODEA external current
anode.
Using filling water and top-up water which does not meet the stated
quality requirements can cause a considerably reduced service life
of the device. The responsibility for this lies solely with the operator.
▪ The plumbing connection must comply with the requirements of
EN12897. The requirements of the following must also be observed:
▪ EN1717 – Protection against pollution of potable water installa-
tions and general requirements of devices to prevent pollution
by backflow
▪ EN61770 – Electric appliances connected to the water mains –
Avoidance of backsiphonage and failure of hose-sets
▪ EN806 – Specifications for installations inside buildings con-
veying water for human consumption
▪ and, in addition, the country-specific legislation.
INFORMATION
The domestic water quality must comply with the EU
Guideline 98/83EC and the regionally-applicable regulations.
The connection of an electric immersion heater or an alternative heat
generator may cause the storage temperature to exceed 60°C.
▪ Scalding protection (e.g. VTA32 + screw connection set 1") must
therefore be fitted during installation.
▪ Use a pressure reducer if the cold water connection pressure
>6bar.
1.2.7 Operation
Only operate the hot water storage tank:
▪ After all installation and connection work has been completed.
▪ With fully installed device covers.
▪ With sanitary side pressure reducers installed (max. 6bar).
▪ With heating side pressure reducers installed (max. 3bar).
▪ With completely filled storage containers (fill level display).
The specified servicing intervals should be adhered to and inspection work must be carried out.
1.2.6 Heating system and sanitary connection
▪ Create a heating system according to the safety requirements of
EN12828.
