Intended use
The system may be used only for the intended purpose.
That means:
•for heating hot water
•for heating support.
•for support in heating swimming pools.
The unit may be operated only within its technical
parameters.
Taking into consideration the ambient conditions, limits
of application and the applicable regulations, every solar
system can be utilised in newly constructed or existing
heating systems.
Overview “Technical Data”
Disclaimer
The manufacturer will not be liable for damage resulting
from unauthorised use of the system.
The manufacturer’s liability will also be voided in the
following cases:
•if work is performed on the system and its
components in a manner that does not comply
with the terms of this operating manual;
• if work is performed on the system and its
components in an improper manner;
•if work is performed on the system that is not
described in this operating manual, and this work
was not expressly approved in writing by the
manufacturer;
•if the system or components in the unit are
modied, redesigned or removed without the
express written permission of the manufacturer.
•The manufacturer is not liable for damages arising
from the on-site removal of snow or ice.

Safety and Security
The system is operationally safe when used for the
intended purpose. The construction and design of the
system meets today's technological standards and
complies with all relevant DIN/VDE regulations and all
relevant safety regulations.
Every person who performs work on the unit must
have read and understood the operating manual prior
to starting any work. This also applies if the respective
person has already worked with such a unit or a similar
unit or has been trained by the manufacturer.
Every person who performs work on the unit must
comply with the applicable accident prevention and
safety regulations. This applies in particular to the
wearing of personal safety equipment.
DANGER!
Prior to designing and assembling the
system, ensure that the underlying surface
has an adequate static load carrying
capacity.
When a wooden frame forms the
underlying surface, an adequate level
of quality, stability and long-term
durability is a must. In order to improve
the substrate, consult with a certied
structural engineer.
DANGER!
When checking and calculating statics, the
snow loading which may occur, according
to the installation location, must be taken
into account and if necessary the xings
strengthened accordingly. Snow build-up
caused by snow-guards is to be avoided.
The distance from the edge of the roof
should be at least 1m.
DANGER!
Danger of fatal injury due to electric
current! Electrical connections may be
installed only by qualied electricians.
Observe the relevant EN-, VDE- and
applicable local safety regulations.
Before opening and connection the
electrical components of the systems,
disconnect the system from the power
supply and secure it from being switched
back on!
ATTENTION
The installation must comply with the appropri-
ate local technological regulations
The properly mounted system may only be con-
nected by an authorised specialist (tter).
STATICS
The static testing is the responsibility of the client!
The underlying structure and fastening are to be
checked by a structural engineer prior to assembly
and designed in accordance with local conditions. When
installing in locations prone to snow and wind, testing of
the fastening construction is necessary.
If the collectors are elevated by means of concrete
blocks or gravel trays, additional protection (wind
bracing) may be necessary.
Customer Services
For technical information please contact a qualied
technician or the manufacturer's local partner.
Warranty / Guarantee
For warranty and guarantee conditions, please refer to
the purchase documents.
NOTICE
Please contact your dealer concerning warranty
and guarantee matters.
Disposal
When decommissioning the system, always comply with
applicable laws, directives and standards for recovery,
recycling and disposal of materials and components .

Building law
Operation of a solar installation is not subject to ofcial
approval. An exception to this rule is installations on
listed buildings
Check whether there is a local obligation to notify the
installation.
Operation
Your decision to purchase a solar system and/or a heat
pump system is a long-term contribution to protecting
the environment through low emissions and reduced
primary energy use.
You can operate and control the solar system with the
control element of the solar and, if applicable, the heat
pump regulator.
NOTICE
Make sure that the control settings are correct.
Operating manual of the solar and heat pump
regulator.
To ensure your solar system operates efciently and in
an ecologically-friendly manner, you should in particular
note the following:
€ENERGY SAVING TIP
Avoid unnecessarily high feed temperatures. For
solar systems which support room heating the
following applies: A lower ow temperature on
the hot water side increases the efciency of the
whole system.
€ENERGY SAVING TIP
When letting in fresh air, do not leave windows
open for an extended period; this will save en-
ergy and reduce your heating costs.
Maintaining the system
When the installation slope is larger than 20°, it is not
necessary to clean the collectors.
All components should be checked and serviced annually
within the framework of regular maintenance.
ATTENTION
The glass surfaces of the collectors may only be
sprayed with tap water; cleaning agents and/or
mechanical cleaning devices are not to be used.
Maintenance
The components of the collector circuit and the heating
circuit (valves, expansion vessels, circulating pumps)
should be inspected annually by a qualied technician
(heating tter).
If the permissible pH value of the solar liquids falls below
7, there is a danger of pipeline corrosion. The solar
liquids are to be completely replaced.
It is a good idea to have a maintenance contract with a
heating installation company. The company will conduct
the required maintenance at regular intervals
The collectors should be inspected at least once a year
within the framework of system maintenance to check
for outward defects.
“Maintenance protocol”.
Malfunctions
In the event of a malfunction, you can read out the cause
of the malfunction via the diagnostic program of the
solar and heat pump regulator.
Operating manual of the solar and heat pump
regulator.
DANGER!
Service and repair work on the
components of the unit may be performed
only by customer service personnel
authorised by the manufacturer.
Please note that the heating components not part of the
solar installation (heat pump, heating circuit, etc.) are
described in the respective operating manuals and, in the
case of malfunctioning, should be handled in accordance
with the information therein.

Transport
Collectors may only be transported using appropriate
and technically inspected vehicles and vehicle bodies.
Auxiliary equipment (crane, boom lift etc.) must be
included according to type of collector and installation.
ATTENTION
Collectors may only be transported using appro-
priate auxiliary equipment. Never lift or trans-
port the collectors by their hydraulic connec-
tions.
Do not subject the collectors to shock or me-
chanical stress.
ATTENTION
Always store collectors dry and protected from
weather.
Installation and assembly
CONDITION OF THE ROOF
ATTENTION
Be sure that rear ventilation is adequate for the
collectors and functioning properly!
Mounting collectors onto rafters is usually enough to
ensure adequate ventilation.
In any case, there must be a thick roof membrane, which
is undamaged and leads to the gutter.
PROTECTING AGAINST DIRT
Ventilation openings on the body of the collector as well
as all collector connections must be protected against
blockage and dirt during installation.
LIGHTNING PROTECTION / EARTHING
ATTENTION
Parts that conduct electricity must be con-
nected to the lightning protection equipment of
the building.
The solar circuit must be connected by an approved
electrician to the foundation earth as well as the
potential equalisation of the building.
If necessary, have metal frames etc. checked by a
lightning protection specialist.
LIMITS OF APPLICATION SYSTEM ASK 26 (Q)
