1.1 Refer to the manual
This manual is intended for authorised and trained technicians who have experience of the proper installation and commissioning
of heating systems on account of their technical training and knowledge.
All activities required for installation, commissioning, operation, and adjustment of the heating system are described in this
manual. For detailed information on the equipment connected to your heating system, please refer to the corresponding manuals.
Please read this manual carefully and thoroughly before proceeding with the installation and initial start-up or modification of the
system.
Relevant documents
The documents listed below are a part of the technical documentation of the ROTEX solar system and must also be taken into
consideration. The documents are included in the scope of supply.
– Domestic hot water storage tank (ROTEX Sanicube, HybridCube, GasSolarUnit): operating and installation instructions.
– Solar panels: the installation instructions included for the applicable installation type.
When connecting to an external heat generator or storage tank which is not included in the scope of delivery, the individual
associated operating and installation instructions apply.
1.2 Warning signs and explanation of symbols

Handling instructions
• Handling instructions are shown as a list. Actions of which the sequential order must be maintained are numbered.
ÎResults of actions are identified with an arrow.
1.3 Avoid danger
ROTEX solar systems are constructed to the state of the art and recognised laws of technology. However, improper use may
result in serious physical injuries or death, as well as property damage. To avoid any danger, only install and operate your
ROTEX solar system:
– as stipulated and in perfect condition,
– with an awareness of safety and the hazards involved.
This assumes knowledge and use of the contents of this manual, of the relevant accident prevention regulations as well as the
recognised safety-related and occupational health rules.
1.4 Intended use
The ROTEX solar system may only be used for providing solar heating support to domestic hot water heating systems. The
ROTEX solar system may only be installed, connected and operated in accordance with the specifications of this manual.
Any other use outside the above-mentioned use is considered as improper. Responsibility for any resulting damage will be borne
by the user/owner alone.
Intended use also includes the observance of maintenance and inspection conditions. Replacement parts must at least satisfy the
technical requirements defined by the manufacturer. This is the case, for example, with genuine spare parts.
1.5 Instructions for working safely
Working on the roof
• Installation work on the roof may only be carried out by authorised and trained persons (heating technicians, roofers, etc.)
under observance of the relevant Accident Prevention Regulations.
• Material and tools must be secured against falling.
• Barriers must be erected to prevent persons from entering the area below the roof where the work is being carried out.
• Observe safety clearances to overhead lines at the installation location.
Before working on the heating system
• All work on the heating system (such as installation, connection and commissioning) may only be carried out by authorised
and trained heating technicians.
• Switch off the main switch and secure it against unintended switching on when carrying out any work on the heating system.
Electrical installation
• Electrical installation should only be carried out by qualified electrical engineers observing the technical electrical guidelines
and regulations of the relevant electric power supply company.
• Before connecting to the mains supply, check that the voltage specified on the type label of the heating system
(230 V, 50 Hz) is the same as the available supply voltage.
Instruct the owner
• Before you hand over the heating system, explain to the user/owner how to operate and check the heating system.
The ROTEX solar system can only be operated in conjunction with the RDS1 pressure system, the
Solaris RPS3 P2 control and pump unit, the RPWT1 plate heat exchanger, and the installation materials
intended for it.

8FA ROTEX Solaris RPS3 P2 - 06/2012
2.2 Brief description
The ROTEX solar system is a thermal system for generating hot water and heating support.
Mode of operation
The V21P, V26P and H26P high-performance flat solar panels convert the sun's radiation into heat with high efficiency. The heat-
transfer medium in the solar panel system is a frost-proof water-glycol mixture, and tap water in the tank circulation system.
As soon as the solar panels have reached a useful temperature level, the liquid in the panel system is pumped through the pressure
station and the plate heat exchanger. The feed pump of the Solaris RPS3 P2 control and pump simultaneously pumps the
unpressurised buffer water in the domestic hot water storage tank through the plate heat exchanger where it absorbs the heat
given off by the solar panel circuit.
Modular design
The system consists of several mainly pre-assembled modules. Plug-in technology and a high degree of pre-assembly ensure fast
and simple installation.
Storage tank
The following can be used as storage tanks for the ROTEX solar system:
– ROTEX Sanicube Solaris: Thermally insulated, non-pressurised plastic storage cylinder.
– ROTEX Hybridcube: Thermally insulated, non-pressurised plastic storage cylinder.
– ROTEX Gas Solar Unit (GSU): Sanicube Solaris with integrated gas condensing boiler.
Electronic control
The fully-electronic control on the Solaris RPS3 P2 control and pump unit provides optimum utilisation of solar heat energy
(hot water heating, heating support) and compliance with all operating safety aspects. All parameters needed for trouble-free
operation have been preset at the factory.
2.3 System components
Control and pump unit RPS3 P2
Construction, operating principle, commissioning, and operation of the storage tank are not described in this
