2.1 Warning signs and explanation of
symbols
2.1.1 Meaning of the warnings
Warnings in this manual are classified according
into their severity and probability of occurrence.
DANGER!
Draws attention to imminent danger.
Disregarding this warning can lead to serious
injury or death.
WARNING!
Indicates a potentially dangerous situation.
Disregarding this warning may result in serious
physical injury or death.
2.1.2 Handling instructions
● Handling instructions are shown as a list.
Actions for which the sequential order must be
maintained are numbered.
Results of actions are identified with an
arrow.
2.2 Avoiding danger
DAIKIN solar installations are state-of-the-art
and are built to meet all recognised technical
requirements. However, improper use may result
in serious physical injuries or death, as well as
property damage. To prevent such risks, install
and operate DAIKIN solar installations only:
– 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.
CAUTION!
Indicates a situation which may cause possible
damage.
Disregarding this warning may cause damage
to property and the environment.
This symbol identifies user tips and particularly useful information, but not warnings or hazards.
Special warning signs
Some types of danger are represented by
special warning symbols.
Electric current

Danger of falling
2.3 Use as intended
The DAIKIN solar system may only be used for
solar-supported heating of hot water systems.
The DAIKIN solar system must be installed, connected and operated only according to the instructions in this manual.
Any other use outside the intended use is considered as improper. The operator alone shall
bear responsibility for any resulting damage.
Intended use also includes compliance with the
maintenance and service conditions. Replacement parts must at least satisfy the technical requirements defined by the manufacturer.
This is the case, for example, with original spare
parts.

2.4 Instructions for operating safety
2.4.1 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.
● 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.
2.4.2 Before working on the heating system
● All work on the heating system (such as installation, connection and initial start-up) may
only be carried out by authorised and trained
heating technicians.
● Switch off the main switch and secure against
being switched on inadvertently when
carrying out any work on the heating system.
2.4.3 Electrical installation
● Electrical installations must only be carried
out by electrical engineers and in compliance
with valid electrical guidelines as well as the
specifications of the responsible energy
supply company (EVU).
● In accordance with IEC 60335-1, connect the
mains via a separator device which exhibits
contact separation in all poles with a contact
opening distance that provides full disconnection in accordance with the conditions of
overvoltage category III and a residual current
circuit breaker (RCD) with a reaction time
≤ 0.2 s.
● Compare the mains voltage (230 V, 50 Hz)
indicated on the nameplate with the supply
voltage before connecting to the mains.
● Before beginning work on live parts,
disconnect them from the power supply
(switch off main switch, remove fuse) and
secure against being switched on again
inadvertently.
● Equipment covers and service panels must be
replaced as soon as the work is completed.
2.4.4 Installation room, water quality, heating
and sanitary connection
The requirements on installing the hot water tank
(EKHWP or Altherma EHS(X/H)), on the water
quality, as well as the heating and sanitary connection are described in detail in the instructions
for the hot water tank. It is essential they are
complied with.
2.4.5 Instruct the owner
● Before you hand over the heating system,
explain to the user/owner how to operate and
check the heating system.
● Document the handover by filling out the
installation and instruction forms together with
the owner and sign them.
2.4.6 Relevant national regulations
● DIN 1055-4: 2005 / EN 1991-1-4 Wind actions
● DIN 1055-5: 2005 / EN 1991-1-3 Snow loads
● DIN 18338 Roofing work
● DIN 18451 Scaffolding work
● DGUV Information 208-016
● DGUV Information 201-054
● DGUV Regulation 112-198
The accident prevention regulations must be
heeded when working on the roof.

3.2 Brief description
The DAIKIN solar system is a thermal solar system for supplying
hot water for consumption and solar support.
The pressure-less system (DrainBack) must only be
used with the EKSRPS4A control and pump unit.
Prerequisite for fault-free operation in the DrainBack
system is that the connecting pipes are laid with a consistent
gradient (at least 2 %) and, with two-way connection, the bottom
edges of the solar panel with constant gradient to the return flow
connection or with equilateral connection, mounted horizontally.
Operating mode
The Solar EKSV21P, EKSV26P and EKSH26P high-performance flat solar panels convert solar radiation into heat with a
high degree of efficiency. The heat carrying medium is water with
which the storage tanks are filled in accordance with the associated installation instructions.
As soon as the solar panels have reached a useful temperature
level, the buffer water in the storage tank (which is not under
pressure) is pumped directly through the panels. With insufficient
panel temperature, the circulation pump is switched off and the
system is drained automatically. This operating mode has
several advantages:
– High operating safety as there are no components (such as
expansion vessel, safety valve, vent valves) sensitive to damage or interference
– Excellent heat transfer and heat storage capacity (system
works without antifreeze agents)
– Minimum maintenance requirements
– Frostproof
– No additional solar heat exchanger required
– No stagnation problems
Modular design
The system consists of several pre-assembled modules. Plug-in
technology and a high degree of pre-assembly ensure fast and
simple system installation.

Storage tank
The following storage tanks can be used for the DAIKIN solar
system:
– DAIKIN EKHWP: Highly thermally insulated, unpressurised
solar stratified tank (with possibility to connect to a DAIKIN
air/water heating pump).
– Daikin Altherma integrated solar unit: Solar stratified tank with
integrated indoor unit of an air/water heating pump.
Design, functionality, start-up and operation of the storage tanks and other Solar components not mentioned in
chap. 3.3 are not described in these instructions.
Detailed information on these components can be found
in the associated operating and installation instructions.
The handling instructions and descriptions mentioned in these
instructions basically apply to all DAIKIN storage tanks that can
be used in this solar system, even if only one type is described
for illustrative purposes. If there are variances to other storage
tanks, special reference is made.
Electronic control
The fully electronic DAIKIN Solar R4 control unit ensures optimum utilisation of the solar heat (hot water heating, heating
support) and the observance of all safety-relevant aspects. All
parameters needed for trouble-free operation have been preset
at the factory.
