Safety

2.1

Intended use

This flat-plate collector is designed to heat a heat transfer medium.
Any other use beyond that described shall be deemed inappropriate.
Observation of these instructions is also part of the correct use
of this appliance.
2.2

Safety information

All steps up to the commissioning of this appliance must only be
carried out by qualified contractors.
Contractors are responsible for adherence to all currently
applicable regulations during installation and commissioning.
Operate the solar thermal system only if it is fully installed and all
safety equipment is fitted.
DANGER Injury
!
Where children or persons with limited physical, sensory
or mental capabilities are to be allowed to control
this system, ensure that this will only happen under
supervision or after appropriate instructions by a person
responsible for their safety. Children should be supervised
to ensure that they never play with the equipment.

Equipment description

The flat-plate collector converts light into heat.
The light penetrates the glass cover. This is made from pre-stressed,
highly transparent single pane safety glass. The light strikes the
absorber and is converted there into heat. The highly selective
coating of the absorber and the thermal insulation on the back of
the absorber reduce heat losses to the ambience to a minimum.
A circulating heat transfer medium is pumped to the DHW cylinder,
thus transferring the energy generated by the collector in the
form of heat. Under certain operating conditions, the inside of
the collector may mist up with condensate. This can happen,
for example, with a large DHW cylinder with low temperature
compared to the environment or high atmospheric humidity.
4.

Operation

The solar thermal system is designed so that no special measures
are required if no hot water is drawn, even for a prolonged period
(e.g. during a summer holiday).
Damage to the appliance and environment
The process medium must not be drained off when the
system is shut down.
5.

Cleaning, maintenance and care

5.1

Annual inspection

Ask your eating contractor to check the solar thermal
h
system annually
.
5.2

Self-cleaning

Generally, solar collectors require no cleaning, as they are largely
self-cleaning. However, in case of severe contamination, e.g. dust
or avian excrement, clean the collector with fresh water.
Damage to the appliance and environment
If you want to clean the collector with water, ensure that
the collector has not already been heated up by strong
sunlight.
5.3

Checking the system pressure

f Regularly check the pressure of the heat transfer medium
at the pressure gauge of the solar module. With a cold solar
thermal system (collector temperature below 30 °C), the
pressure should be between 0.35 and 0.4 MPa.
Notify your heating contractor if you notice large deviations from
the set value.
