1. General
Before commissioning your new solar module, please read all chapters
thoroughly and, in particular, please note the warnings given in champter 3.
Improper handling or operation may lead to damage of the system.
1.1. Use
The solar module 50 enables the buffer tank to be loaded depending
]on the temperature. The solar module is speed controlled, energy
efficient and suitable for large buffer tanks.
1.2. Sample application

4
2. Description
The solar module 50 is used to connect a solar collector plant up to
50 m² in
size to a buffer tank. The solar heat is transferred from the collector circuit to
the buffer circuit using highly efficient heat exchangers.
In the process, an intelligent system provides optimal interaction between the
solar pump and buffer loading pump depending on the solar radiation and
ensures a high efficiency level of heat transfer.
The module loads the buffer using speed control and the corresponding
temperature zone of the buffer depending on the temperature.
3. Warnings
The system must be installed and operated in accordance with the
locally applicable specifications and standard practices.
Only qualified technical personnel should carry out the assembly,
maintenance and cleaning of the shift layer module.
Unauthorised modifications or changes are not permitted on the
system for safety reasons and inevitably lead to the warranty becoming
null and void.
The operating pressures specified should not be exceeded!
If any errors occur –regardless of the type –please contact your
heating system installer. Please do not carry out any repairs to the
plant yourself, since this is not permitted by law and you could expose
yourself to hazards as a result.
4. Structure of the solar module
We reserve the right to make
constructional modifications on account
of advanced technical development. Each
of these modifications shall be taken into
consideration in the operating manual by
replacing the relevant pages or revising
the electronic media (CD ROM). The
module may sometimes vary from the
appearance given in the illustration!

The module must be connected taking the following standards, national guidelines
and the regulations of the local water utility company into consideration.

This appliance is not intended for use by persons (including children) with
limited physical, sensory or mental abilities or with a lack of experience
and/or knowledge, unless they are being supervised by a person who is
responsible for their safety, or have received instructions from such a
person regarding its use. If the mains connection line of this appliance is
damaged, it must be replaced by the manufacturer or their customer
service or a person having similar qualification, in order to avoid hazards.

6. Assembly and commissioning
Before you start the assembly, please keep the following in mind:
Read the entire operating manual and pay particular attention to the section
on Warnings.
This appliance is not intended for operation by persons (including children)
with limited physical, sensory or mental abilities.
Uninformed or inexperienced persons are permitted to operate the
appliance only under the supervision or instruction of a person responsible
for the safety.
The installations must meet the respective official requirements.
6.1. Assembly
The erection and installation must be done by an approved technical agency.
This agency also takes over the responsibility for correct installation and
commissioning. A dry, frost-free room that provides sufficient space for
maintenance work is required as the installation site.
The solar module must be installed so that it is protected from splashing
water and should be run only at room temperatures below 40°C.
6.2. Positioning the solar module
Installation near the buffer tank is recommended to avoid heat losses. This
should be done on an even surface as far as possible and one that is statically
suitable, whereby adjustable legs have been provided for the purpose of levelling.
Tightening the mounting screws too tightly damages the insulation.

7
Wall mounting
The appliance is mounted on the wall using the fixing material supplied (3 x M8
hanger bolts, M8 nuts and 3 flat washers M8) as follows:
1. As given in the Drilling jig enclosed, drill the boreholes marked with the 10 mm
dia. drill bit at least 8 cm deep.
2. Next, insert the dowels into the borehole and screw in the hanger bolts into
the brickwork until the dowel threads are no longer visible.
3. Now hang the solar module on the threaded bolts and mount it using the
flat washers and nuts.

Mounting the tank
Before mounting the module, the buffer sensors must be mounted in the terminal
strip of the buffer.
The installation on the tank takes place using the installation material in 3
steps as follows:
Step 1: (Figure above) Step 2: (Figure above)
Mount and tighten the
3 threaded rods and the
3 corrugated pipe hoses
including the gaskets at the
relevant connecting points on
the tank.
Push the shift layer module over the
corrugated pipe hoses and the threaded
rods and fix the module to the tank
using the flat washers and nuts.
Step 3: (Figure on the right)

10
Tighten the 3 corrugated pipe
hoses with the gaskets on the
module.
6.3. Hydraulic connection
The pipelines are connected in accordance with the installation layout of this
manual. See 1.2. Sample application:
The path of the lines to the tank should be as short as possible!
We recommend steel or copper pipes as the material for the lines. The
installation sequence must be followed for all pipelines and fittings in order
to prevent electrochemical corrosion.
Installation in gravitational heating systems is not permissible!
The expansion tank of the collector circuit must be connected directly.
The installation of shut-off valves (except suitable maintenance units such as
cap valves) is not permitted!
Connections must be tightened only after the pipelines have been sealed.
Tightening torques or impact of forces on components and connections that
have already been pre-mounted must be avoided at all costs!
In addition, all flat seal connections must be checked for the right tightening
torque of the union nuts (screw connections may become loose during
transport!).
6.4. Electrical connection
The electrical components of the plant have been wired internally at the factory.
Connection to the mains supply (230 V/AC, 50 Hz) takes place using the power
supply line already connected to the terminals.
The buffer sensors supplied with the appliance are placed at the appropriate
measuring points of the buffer tank and connected to the corresponding
terminals of the controller in the same manner as the collector sensor included in
the scope of delivery. The controller manual contains comprehensive information
on the controller integrated in the module.
Work on live parts of the module is carried out only after following the respective
regulations of the electricity supply company and the relevant standards
applicable.
