CAUTION
Open the hot water intake valves before
heating the system up for the first time or
after a longer break in its operation in order
to check whether the storage tank is filled
with water and the cut-off valve at the cold
water inlet is not closed.
Thermal Insulation of
the System
In order to minimize thermal energy losses, insulate
all connector pipes, pipelines and temperature sensor
covers thoroughly after the installation of the unit and
performance of the leak proof test. For this purpose,
use thermal insulation of correctly selected thickness
and thermal insulation parameters.
TIP
Lack of thermal insulation, its incorrect thick-
ness or insulation made of inadequate ma-
terials will cause decrease of thermal insu-
lation properties of the unit and the system.
Warnings and Practical
Recommendations
CAUTION
To prevent bacterial growth we recommend
to make sure a periodically increase of hot
water temperature for a shorter time at reg-
ular intervals e.g. every 14th day.
We recommend the following:
•
Check the operation of the safety valve as de-
scribed by the manufacturer of the valve in order
to check whether it is not clogged.
•
Clean the inside of the storage tank periodically.
Cleaning intervals depends on the hardness of
the water present in a given area.
•
To ensure optimum protection of the storage
tank against corrosion, we recommended check-
ing the level of wear of the isolated magnesium
anode once a year.
•
In the systems with the electric heating unit, en-
sure that the electrical installation is properly pro-
tected by protective circuit.
•
In order to eliminate any odour of hydrogen sul-
phide (caused by bacteria in the oxygen deficient
water), we recommend observing the periodic
cleaning of the tank and replacement of the an-
ode and, in addition periodically increase the hot
water temperature in tank to prevent bacterial
growth.

Connection and start-up
•
Limit the setpoints of the heating medium tem-
perature controllers in the storage tank supply
lines to 80 °C in order to avoid triggering of the
thermal cut-off in the electric heating module.
•
In order to reduce the possibility of scalding by
the water, we recommended to set the water
heating temperature in the storage tank (of both
the heating unit and the coil) so, that it does not
exceed 60 °C. This will also help to extend the life
of the storage tank.
•
Report any malfunctions in the storage tank op-
eration to the authorized service centres. You can
find the complete list of our authorized service
centres at our website.
It is forbidden to:
•
Activate the heating medium circuit or electric
heating unit if the tank is not filled with water.
•
Use the storage tank, if you find any malfunction
of the safety valve.
•
Install any device (such as cut-off and/or check
valves, etc.) between the storage tank and the
safety valve (except T-pipes).
•
Make any unauthorized repairs.
•
Stop water leaks from the safety valve.
•
When heating with only the electric unit, the coil
circuits may not be isolated.
CAUTION
Systematic admission of fresh, untreated
water to the heating circuit (coil) increases
the risk of corrosion inside the coil.
