008.1633099_00 – 06/2020
▪ Chloride: ≤250 mg/l
▪ Sulphate: ≤250 mg/l
▪ pH value (heating water): 6.5 – 8.5
Using filling water and top-up water which does not meet the stated
quality requirements can cause a considerably reduced service life
of the equipment. The responsibility for this lies solely with the
operator.
1.2.6 Heating and sanitary side connection
▪ Create a heating system according to the safety requirements of
EN 12828.
▪ With sanitary connection, you must observe
▪ EN 1717 – Protection against pollution of potable water
installations and general requirements of devices to prevent
pollution by backflow.
▪ EN 806 – Specifications for installations inside buildings
conveying water for human consumption.
▪ and, in addition, the country-specific legal regulations.
INFORMATION
The domestic water quality must comply with the
EU Guideline 98/83 EC and the regionally-applicable
regulations.
The connection of a solar installation, an electric heating rod or an
alternative heat generator may cause the storage temperature to
exceed 60°C.
▪ For this reason you should fit scalding protection (e.g. VTA32 +
Screw connection 1")
▪ Use a pressure reducer if the cold water connection pressure
>6 bar.
If the hot water storage tank is connected to a heating system with
steel pipes, radiators or non-diffusion-proof floor heating pipes, slurry
and swarf could enter the hot water storage tank and cause
blockages, local overheating or corrosion.
▪ To prevent possible damage, fit a dirt filter or sludge separator into
the heating return flow of the system.
▪ SAS 1
INFORMATION
To avoid heat losses caused by gravitational circulation,
circulation brakes SKB shall be installed into the
connections.
1.2.7 Operation
Only operate the hot water storage tank
▪ After all installation and connection work has been completed.
▪ With fully installed equipment covers and service accesses.
▪ With sanitary side pressure reducers installed (max. 6 bar).
▪ With heating side pressure reducers installed (max. 3 bar).
▪ With completely filled storage containers (fill level display).
The specified servicing intervals should be adhered to and
inspection work must be carried out.
1.3 Handover to operator and warranty
1.3.1 Instructing the owner
▪ Before you hand over the device, explain to the owner how he/she
can operate and check the device.
▪ Hand over the technical documentation (at least the operating
instructions and operating manual) to the operator and advise him
that these documents must be made available at all times and be
stored in the immediate vicinity of the device.
▪ Document the handover by filling out the installation and
instruction forms together with the owner and sign them.
1.3.2 Warranty conditions
The legal guarantee conditions fundamentally apply. Our more
extensive warranty conditions can be found in the Internet. Ask your
suppliers if necessary.
There is only an entitlement to warranty services when it can be
certified that the annual maintenance work has been regularly
completed.
