Product informaon HSK‐SLS
Locaon
The tank hast to be located in a frost‐protected place. Ice formaon inside the system may lead to the
tank’s destrucon.
The locaon has to have the necessary space for maintenance and repair work, as well as sufficient
load‐bearing capacity of the ground!
Site clearance for dismounng the tank and for transport has to be ensured permanently.
Insulaon
The insulaon has to be mounted before piping begin.
Do not get near the insulaon with fire, brazing flame, welding torch, etc.; fire hazard!
Piping
The tank is to be installed in accordance with the piping diagram [chapter: Descripon of
connecons]. This diagram is only a mounng proposal and does not replace professional planning.
The connecon has to be carried out in accordance with DIN. .
The minimum diameter of the safety valve has to be DN20 (¾").
Aenon has to be paid to possible electro‐chemical reacons when choosing the installaon
material (mixed installaon)! Galvanzied pipe installaons have to be replaced.
With DHW temperatures of more than 60°C it is generally recommended to limit the temperature by
a mixing valve to 60°C!
The connecon components have to be aligned to these temperatures or the temperature has to be
limited by means of a mixing valve!
Operang pressure
The permissible operang pressures according to our technical specificaons [chapter: technical
specificaons] have to be observed. Exceeding the permissible operang pressure may lead to leaka‐
ges and destrucon of the tank!
Pressure‐reducing valve
The installaon of a pressure‐reducing valve is recommended. If the DHW supply is operated with
higher pressure a pressure reducing valve has to be installed.
In order to reduce sounds caused by fluxion inside the building the pipeline pressure should be
adjusted to approx. 3,5 bar.
DHW filter
It is highly recommended to install a DHW filter in the cold water pipeline since floang parcles may
block fings, etc. and may cause corrosion in the pipes.
Installaon / Allgemeine Informaonen

Product informaon HSK‐SLS
Safety devices
The tank has to be equipped with a non‐lockable safety valve. Moreover, an expansion vessel has to
be installed that is dimensioned according to the tank’s capacity. It is to be locked only with a cap
valve.
An expansion vessel for sanitary water has to be installed for the stainless steel heat exchanger.
A safety temperature limiter has to be installed in accordance with heang system regulaons for
scalding protecon means.
Next to the exhaust line of the safety valve, or even beer, on the valve itself, an indicaon plate has
to be installed, saying: :
"Water is leaking from the valve’s pipe for safety reasons during the heating. Do not close!"
Draining/de‐airing
The tank hast to be installed in such a way that it can be drained without demounng it.
While draining, hot water might exit and cause injuries.
The upper socket is provided for de‐airing the tank.
We do not recommend the use of an automac bleeder.
Immersion heater (oponal)
The tank can addionally be equipped with an electric heang element. You have to respect the
regulaons of your local public ulity when installing an immersion heater.
The electric heang elements have to be insulated. It is only with insulaon that the corrosion
protecon is guaranteed.
Electric heang elements with insulaon and integrated temperature control and safety temperature
limiter are oponal available at Solarbayer.
If electric heang elements without insulaon are used, the tank’s warranty expires. .
Inial operaon
Connecons that are not used have to be sealed professionally with plugs.
Thoroughly rinse pipes and tank aer mounng, heang system has to filled with treated water
according to VDI 2035 and bleeded.
Note for installers :
Record the pressure test and the proper filling of the heang system with water in accordance with
VDI 2035 and let it countersign by your customer.

Insulaon
Inappropriate insulaon of the tank’s boom is
unacceptable.
Tank sockets are available for all popular tank
types up to 1000 Liter. You can increase the
energec efficiency with a perfect boom
insulaon. Especially when renovang old
buildings an addional insulaon at the boom
is recommended. Our tank socket is an easy to
realize alternave for this since it has excellent
insulaon characteriscs.
Our tank sockets are made of galvanized steel
and the rear side is insulated with flexible foam.
