Inform the end user that the specifications for domestic
hot water apply.

Setting the hot water thermostatic mixer
Warning.
Risk of burns from contact with compon-
ents carrying hot water.
There is a risk of burns from the cylinder and
all components carrying hot water that are
located close to the cylinder. In solar mode,
the cylinder temperature can rise to 80 °C.
▶
When setting the thermostatic mixer, do
not touch the hot water pipes.
Warning.
Risk of burns if the temperature is set too
high.
There is a risk of scalding at the hot water
draw-off points if the water temperature is too
high.
▶
Check the temperature at a draw-off point
and set the thermostatic mixer to a value
below 60 °C.
Note
The hot water thermostatic mixer protects against
high temperatures in the hot water installation.
The hot water from the cylinder is mixed with cold
water in the thermostatic mixer and is thereby
heated to the maximum required temperature
between 40 °C and 60 °C . The hot water ther-
mostatic mixer is set to 60 °C at the factory.
Due to energy losses in the hot water pipe, the
temperature at the draw-off points is always lower
than the temperature that is set at the thermo-
static mixer.

1.
Set the cylinder temperature to 65 °C and wait until this
value has been reached.
Note
Depending on the temperature setting for the
cylinder, the auxiliary heater is activated if
the solar heating is not sufficient for achiev-
ing the target temperature.
2.
Measure the hot water temperature at a draw-off point
and set the thermostatic mixer to the position that cor-
responds to the maximum temperature that is required
by the operator.

Each additional temperature boost causes unneces-
sary energy consumption.

To optimise solar energy consumption in the summer,
reduce the minimum hot water temperature to 45 °C.

Observing inspection and maintenance
intervals
Proper regular inspections (once a year) and maintenance
(depending on the result of the inspection, but at least once
every two years) combined with the exclusive use of original
spare parts are decisive factors in ensuring smooth opera-
tion and long working life for the product.
We recommend taking out an inspection or maintenance
contract.
Inspection
The inspection is intended to determine the actual condition
of the product and compare it with the target condition. This
is done by measuring, checking and observing.
Maintenance
Maintenance is required in order to eliminate any deviations
of the actual condition from the target condition. This is nor-
mally done by cleaning, setting and, if necessary, replacing
individual components that are subject to wear.
Based on experience, it is not necessary to carry out annual
cleaning, e.g. on heat exchangers, under normal operating
conditions. The maintenance intervals and the scope of the
maintenance intervals are determined by the specialist in-
staller depending on the conditions on inspection. It is nev-
