1.1 Observing Instructions
This manual is intended for authorised and trained technicians who have experience in the proper installation and commissioning
of solar systems on account of their technical training and knowledge.
All procedures required for installation, commissioning, operation and adjustment of the system are described in this instruction
manual and associated instruction manuals. Please read this manual carefully and thoroughly before proceeding with the instal-
lation and initial start-up or modification of the system.
Relevant documents
For configuration with the air-water heat pump EKHBH*/EKHBX* (pressurised system ):
– Control and pump unit for solar systems (pressurised system) EKSR3PA/EKSRDS1A.
– Solar add-on for air-water heat pump system KKSOLHWAV1.
– Process water for air-water heat pump EKHWE*/EKHWS*.
For configuration with the air-water heat pump EKHBRD*(unpressurised system ):
– Control and pump unit for solar systems (unpressurised system) EKSRPS3.
– Hot water storage tank for air-to-water heat pumps EKHWP*.
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.

Special warning signs
Some types of danger are represented by special symbols:
Handling instructions
• Handling instructions are shown as a list. Actions of which the sequential order must be maintained are numbered.
Results of actions are identified with an arrow.
1.3 Avoid danger
The DAIKIN Solar system are manufactured using state-of-the-art technology and recognised technical rules. However, improper
use may result in serious physical injuries or death, as well as property damage. To prevent danger, the DAIKIN Solar system
should be only installed and operated:
– 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 DAIKIN Solar system must be used exclusively for hot water generation and for solar heating support of hot water heating
systems. The DAIKIN Solar system may only be installed, connected and operated according to the information in this manual.
Any other use outside the intended use is considered as improper. Responsibility for any resulting damage will be borne by the
user/owner alone.
Proper use also includes observing the relevant maintenance and servicing conditions. Replacement parts must at least satisfy
the technical requirements defined by the manufacturer. This is the case, for example, with genuine spare parts.
Electrical current Danger of burning or scalding
Validity
This instruction applies especially to on-roof mounting of the solar panel area. For other types of installation (in-roof, flat roof
mounting) the instructions for the individual type of installation are applicable. The operating and installation instructions of the
respective control and pump unit are to be observed when installing piping and commissioning.
Only applicable for the unpressurised system (Drain Back) Only applicable for the pressurised system

1.5 Instructions for operating safety
Working on the roof
• Installation work on the roof may only be carried out by authorised and trained persons (heating technicians, roofers, etc.) in
compliance with the relevant Accident Prevention Regulations and with the use of suitable personal protection equipment.
• Material and tools must be secured against falling down.
• Barriers must be erected to prevent persons from entering the area below the roof where the work is being carried out.
Before working on the heating system
• All work on the heating system (such as installation, connection, and start-up) may only be carried out by authorised and
trained heating technicians.
• Switch off the mains supply before starting any work on the heating system and secure it against unintentional switch-on.
Electrical installation
• Electrical installations must only be conducted by electrical engineers and in compliance with valid electrical guidelines as
well as the specifications of the energy supply company.
• Before connecting to the mains supply, check that the voltage specified on the type plate of the heating system (230 V,
50 Hz) is the same as the available supply voltage.
• Before beginning work on live parts, disconnect them from the power supply (switch off main switch, remove fuse) and
secure against unintentional restart.
• Equipment covers and service panels must be replaced as soon as the work is completed.
Instructing the user/owner
• Before you hand over the heating system, explain to the user/owner how to operate and check the heating system.
• Hand over the technical documentation (this document and all supporting documents) to the user/owner and advise him that
these documents must be made available at all times and be stored in the immediate vicinity of the unit.
• Document the handover by filling out the installation and instruction forms together with the owner and sign them.

2.2 Brief description
The Solar system is a thermal solar system for hot water generation and heating support.
The system consists of several, mainly pre-assembled, modules. Plug-in technology and a high degree of pre-assembly ensure fast
and simple system installation.
Unless specified otherwise, the components are not included in the scope of delivery and need to be ordered separately.
Electronic control
The fully-electronic Solar system R3 controller ensures optimum solar heat exploitation (hot water heating, heating support) and
compliance with all operational safety aspects. All parameters needed for trouble-free operation have been preset at factory.
2.3 System components for all systems
High performance flat solar panels
Solar panel mounting rails FIX-MP
The unpressurised system (drain back) must only be operated with the regulation and pump unit EKSRPS3,
the air-to-water heat pump EKHBRD*, the hot water storage tanks EKHWP* and the relevant components
(chapter 2.3 and 2.4).
The pressurised system must only be operated with the pump unit EKSR3PA, the pressure station
EKSRDS1A, the plate heat exchanger EKSRPWT1, with the heat pump EKHBH* or EKHBX*, the solar connection
kit EKSOL, the hot water storage tanks EKHWE/EKHWS and the relevant components (chapter 2.3 and 2.5).
