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.
4.
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-
ertheless necessary to carry out maintenance work at least
every two years.
9.3
Procuring spare parts
The original components of the product were also certified
by the manufacturer as part of the declaration of conformity.
If you use other, non-certified or unauthorised parts during
maintenance or repair work, this may void the conformity of
the product and it will therefore no longer comply with the
applicable standards.
We strongly recommend that you use original spare parts
from the manufacturer as this guarantees fault-free and safe
operation of the product. To receive information about the
available original spare parts, contact the contact address
provided on the reverse of these instructions.
▶
If you require spare parts for maintenance or repair
work, use only the spare parts that are permitted for the
product.
