3.2System concepts
DAIKIN Solar system are generally assembled in accordance with the installation concept shown below. This also includes the
possibility of connection on the opposite side of the flat solar panels in each case.
– The connection on opposite sides is recommended by DAIKIN (possible from 1 flat solar panel upwards).
– Alternate side connection is acceptable for both DAIKIN Solar system (
For the Solar panels - flat roof installation of the flat solar panels, the roof surface must have an inclination of
less than 5°. With roof inclinations of 15° to 80°, the flat solar panels can be mounted on the roof or integrated
in the roof skin. Further information is provided by the installation instructions of the DAIKIN Solar system onroof installation pack and the DAIKIN Solar system in-roof installation pack.

tank EKHWP* (shown in the drain-back system ).
3.3Laying connection pipes
Installation instructions concerning differences between non-pressurised and pressurised system
Non-pressurised system (Drain Back) Pressurised system
With solar panels connected at opposite ends, the whole
solar panel array must be set up with at least 0.5% gradient to the lower panel connection (return flow).
The connection pipe must be set up with a continuous gradient
of at least 2% and without any counter gradient.
Tab. 3-1Installation instructions
No particular minimum gradient of the solar panel array is
required. A gradient from the lower (return flow) connection
should however be avoided.
The connection pipe between the solar panel array and the hot
water storage tank must be made of pressure-resistant metal
piping (CON XP16 / CON XP20 or Cu Ø 22 mm). The use plastic
piping is not allowed.

3.3.1Non-pressurised System
CAUTION!
Siphon action may never be allowed to occur anywhere in the pipe run between storage tank and the flat solar
panel. This could lead to functional faults and even material damage.
In the case of longer horizontal pipe runs with only a minimum gradient, it is possible for water pockets to
develop due to thermal expansion of the plastic pipes between the mounting points with siphon action:
• Always make sure that pipe runs have a continuous gradient of at least 2%.
• Fix the pipes in the optional support troughs TS (see page 12) or run them along a rigid auxiliary structure
(e.g. profile rail, pipe etc.).
• DAIKIN recommends always using the support trough kits (TS) for extended horizontal pipe sections.
• Lay prefabricated connection pipes (feed and return flow) with integrated sensor cable (see chapter 2.4 "System components
for the unpressurised system") between the planned installation site of the solar panel area in the inner roof and the installation location of the hot water storage tank with control system and EKSRPS3 pump unit.
– Make sure there is adequate length for connection to the hot water storage tank and the flat solar panels.
– Make sure that there is a constant gradient in the connecting pipes (min. 2%).
– The maximum permissible overall pipe length must not be exceeded (see tab. 3-2).
Number of solar panels Max. possible total length
of pipe
245m
330m
417m
515m
If larger distances need to be covered, calculations
need to be made for the dimensioning of the connecting pipes.
Contact DAIKIN Service.
Tab. 3-2Maximum lengths of the DAIKIN connection pipes
Additional notes about connecting pipes
If on-site conditions make it impossible or very difficult to install the connecting pipes in the manner described above, slight deviations from the specified installation are permitted. Hereby, the inflow pipe may not be larger than 18 x 1 mm.
1. If vertical copper pipes are already installed in the house, they can be used if a continuous connection pipe gradient can be
guaranteed and the maximum pipe diameter must not be exceeded.
2. If a uniform gradient from the second roof penetration to all pipe sections cannot be guaranteed when the solar panels are
connected at opposite ends, then for roof penetration purposes, the inflow pipe can be connected to the top of e.g. through
a ventilating tile, if:
– the highest point if the inflow pipe is not more than 12 m above the storage tank mounting floor level,
– the internal diameter of the inflow pipe is not more than 16 mm.
– a continuous rise of the inflow pipe to the highest point, as well as a continuous gradient to the storage cylinder is
ensured.
3. For pipe runs in which only a limited gradient can be achieved, copper pipe should be used on site. This avoids the need for a
rigid supporting structure, and prevents the formation of water pockets due to expansion of the plastic pipes.
3.3.2Pressurised system
The connection pipe between the solar panel array and the hot water storage tank must be made of pressure-resistant metal
piping (CON XP16 / CON XP20 or Cu Ø 22 mm). The use plastic piping is not allowed.

3.4Installing flat solar panels
DANGER!
There is an increased accident risk during work on a roof. When working on the roof, the general accident
prevention regulations must be observed to prevent accidents. Installation work on the roof must only be
carried out by authorised and trained personnel.
• Before starting the installation work, check that the roof structure has adequate carrying capacity and is
undamaged (e.g. defective battens or leaks).
• Use of tools etc. only in accordance with the applicable accident prevention regulations.
• Marking of the workplace (danger of parts falling down).
WARNING!
After their packaging is removed, the flat solar panels will become hot very quickly if they are exposed to the
sun's rays.
• Wear protective gloves.
• Remove protective caps (not heat-resistant) after positioning the flat solar panel.
CAUTION!
Frost or overheating can damage the system.
• Permit the system to drain.
• Make sure that the flat solar panels are installed so that their lower edge is always higher than the Solar
system-inflow coupling of the storage tank.
CAUTION!
Damage to roof skin.
• Do not slide any sharp or pointed objects along the flat roof.
Notes for safe and trouble-free operation
• Mount the solar panel with a gradient to the lower collector coupling (return flow).
• Always run the connection pipe between the flat solar panels and the hot water storage tank with continuous gradient to
avoid a siphon effect (opposite gradient) over the whole connection run.
• The upper edge of the flat solar panels may not be more than 12 m above the storage cylinder(s) mounting floor level.

CAUTION!
Siphon action may never be allowed to occur anywhere in the pipe run between storage tank and the flat solar
panel. This could lead to functional faults and even material damage.
• With solar panels connected at opposite ends, the whole mounting rails with minimum 0.5% gradient to the lower solar panel connection (return flow) must be set up to avoid Siphon-effect (anti-gradient).
• Set up both mounting rails exactly flat and parallel to each other on the marking line A (HA) (see fig. 3-11).
If needed, the mounting rails inserted in suitable way.
CAUTION!
In order to prevent torsional stresses and fixing difficulties when mounting the solar panels;
• Only slightly tighten the self-tapping screws on the sliding blocks during the installation.
• Align both both mounting profile rails exactly flat on the flat roof frame and parallel to each other
(see fig. 3-11). If needed, the mounting rails inserted in suitable way.
• At the end of the installation, and after checking, tighten all the bolts.

3.4.31. Installing flat solar panel
CAUTION!
There will be a danger of injury to persons and damage to materials if flat solar panels are installed which do
not fit exactly. They may be ripped away by high wind and snow loads.
• To ensure proper use, use only genuine DAIKIN accessories and installation materials for installing DAIKIN
flat solar panels.
CAUTION!
In order to prevent torsional stresses and fixing difficulties when mounting the solar panels;
• Lightly tighten the self-locking nuts of the slide blocks,
• Align both both mounting profile rails exactly flat on the flat roof frame and parallel to each other
(see fig. 3-11). If needed, the mounting rails inserted in suitable way.
CAUTION!
In the Drain-Back system, as opposed to the pressurised system, the flat solar panels need to be installed
rotated through 180°, since otherwise partial snow covering of the flat solar panel and if there is a danger of
frost, the solar system cannot operate efficiently and frost damage may occur.
• Install flat solar panels rotated through 180° in the Drain-Back system, as depicted on the covering film.
• Always fit the solar panel temperature sensor at the bottom in one of the two side installation openings
in the Drain-Back system.
• The different mounting position for the solar panel temperature sensor is only supported above
version 4.2 on the R3 controller.

3.4.4Installing another flat solar panels
DANGER!
If the clamping blocks are incorrectly positioned and installed (hammer bolt not clicked in place in the mounting
rail), the fixing of the solar panel array on the supporting structure cannot be guaranteed under unfavourable
weather conditions. This may cause personal injury.
• Visual checking of the correct installation of the clamping blocks is imperative.
• In particular, you should check the double clamping blocks (point 1.) because these are fixed at the joint
position of two mounting rails.
CAUTION!
If the retaining clips do not clip in place audibly, the DAIKIN Solar system can develop leaks and thus restrict
the operational safety.
Reasons for the retaining clamps not engaging:
– Flat solar panels not completely pushed together.
– Absorber position moved (push the absorber into the connections on the opposite side in the correct posi-
tion, wearing protective gloves).
CAUTION!
If the connections on the flat solar panel (FIX-VBP) are not fitted with extreme caution, the seal ring can get
damaged. This causes leaks in the system.

3.4.5Hydraulic connection of the flat solar panel (non-pressurised system)
CAUTION!
Siphon action may never be allowed to occur anywhere in the pipe run between storage tank and the flat solar
panel. This could lead to functional faults and even material damage.
In the case of longer horizontal pipe runs with only a minimum gradient, it is possible for water pockets to
develop due to thermal expansion of the plastic pipes between the mounting points with siphon action:
• Always make sure that pipe runs have a continuous gradient of at least 2%.
• Fix the pipes in the optional support troughs TS (see page 12) or run them along a rigid auxiliary structure
(e.g. profile rail, pipe etc.).
• DAIKIN recommends always using the support trough kits (TS) for extended horizontal pipe sections.
If the connecting pipe of CON 15 or CON 20 is not long enough for the distance between the hot water storage tank and solar
panel array, it can be lengthened, whereby the number of solar panels must be taken into account.
Pipe extension kits CON X 25 (2.5 m), CON X 50 (5 m), and CON X 100 (10 m) are available.
• Take account of the instructions concerning lengths of pipe in tab. 3-2.

Instructions on pipe installation
• Run the connecting pipe with a continuous gradient between the flat solar panels and the storage tank.
• Connect the solar panel array alternately, and align it so that the bottom return flow coupling is located at the lowest point
of the solar panel array (see section 3.2).
The differences between the connection points and dimensions of the inflow connection pipe (at the top of the
flat solar panel / VA 15 Solar) and the return flow connection pipe (at the bottom of the flat solar panel /
VA 18 Solar) make it impossible to confuse one pipe for the other.
• However, you must ensure that the inflow and return flow pipes on the flat solar panel are labelled as heat
generators.
This instruction manual only describes the pipe laying for alternate end connection with two roof breakthroughs.
In principle there is a possibility of having an alternative connection with a single roof transit.
• In this case, you should always make sure that the flow line is installed along the frame at the necessary
gradient in order then to lay this also at the side of the return flow line through the roof transit.
Connect the connecting lines
1. Lay the connection pipes up to the roof penetration and fix in position (e.g. with clamps).
2. Carefully cut the thermal roof insulation below the roof penetration, so that the return flow pipe (VA 18 Solar) can be pulled
out.
CAUTION!
Leaking vapour barriers can lead to building damage.
• Reseal the vapour barrier from the inside at the penetration points of the connecting pipes and cable.
CAUTION!
If plastic pipes are damaged, there is a risk that they will break.
• When cutting through the thermal insulation, never damage the surface of the VA Solar system connecting
pipes.
3. Lay the connecting pipes along the flat solar panels up to the solar panel
connection and cut off the thermal insulation on the connecting pipes at the
solar panel connection.
The transit can be carried out directly at the individual flow or return connection on the flat solar panel or underneath the solar panel array.

3.4.6Hydraulic connection of a flat solar panel(pressurized system)
WARNING!
Danger of burns from hot solar panel couplings and hot solar panel frame.
• Do not remove the cover of the solar panel until hydraulic connection work has been completed.
• Do not touch hot parts.
• Wear protective gloves.
CAUTION!
Danger of scalding if incorrect connection pipes are used.
• Use only connecting lines made of pressure-resistant metal pipes (CON XP16 / CON XP20 or Cu Ø 22 mm)
between the Solar system solar panel and plate heat exchanger.
• The use plastic piping is not allowed.
Instructions on pipe installation
The connection fittings included in the EKSRCP connection kit have compression ring joints for copper piping Ø 22 mm.
We therefore recommend, as the connecting lines between the Solar system solar panel and the hot water storage tank, using
the DAIKIN CON XP16 / CON XP20.
Connect the connecting lines
1. Lay connection pipes between the flat solar panels and the location of the hot water storage tank.
– Connect the Solar system solar panels on alternate sides and align so that the return flow connection is at the lowest
point of the Solar system solar panel (see section 3.2). The feed pipe should preferentially be connected at the opposite
end at the top of the solar panel.
– In the process, thermally insulate the connection pipes indoors.

3.4.8Installing solar panel temperature sensor
CAUTION!
Plastic connection pipes will not conduct voltages induced by electrical storms. Under adverse circumstances,
these voltages can extend through the solar panel sensor up to the control and thus damage both.
• Carry out equipotential bonding ("Earthing") between foundation earth connection and solar panel array.
This should only be performed by an authorised specialist (electrician) in accordance with the local regulations.
The installation openings for the solar panel temperature sensor are located on the left and right on the side
solar panel frame and are closed off with plugs in the as-delivered condition.
In the Drain-Back system, as opposed to the pressurised system, the flat solar panels are installed rotated
through 180°. This produces the following mounting positions for the solar panel temperature sensor:
– at the bottom edge of solar panel
– at the top edge of solar panel
The different mounting position for the solar panel temperature sensor is only supported above version 4.2 on
the R3 controller.
• Fit the solar panel temperature sensor in the flat solar panel at the position where the feed pipe is
connected.
The mounting openings for the solar panel temperature sensor are located to the left and right at the top of the side solar panel
frame, approx. 10cm below the upper connection. The mounting openings are fitted with plugs in the as-delivered condition.
Fit the solar panel temperature sensor in the flat solar panel at the position where the feed pipe is connected.
1. Remove the sensor plugs (fig. 3-40).
2. Push solar panel temperature sensor up to the stop in the flat solar panel (fig. 3-40). The sensor must be clamped to the
absorber plate.
3. Run the silicone-covered sensor cable to the roof penetration box (with drip-off elbow), and secure it to the inflow connection
line (fig. 3-41).
CAUTION!
Moisture can damage the temperature sensor.
• When securing the cable, make sure that no rainwater can run down the cable to the sensor well (installing
with drip-off elbow see fig. 3-41).

are included in the installation and maintenance instructions of the regulating and pump unit ( EKSRPS3 or EKSR3PA
+ EKSRDS1A).
4.2Decommissioning
4.2.1Temporary shutdown
CAUTION!
A heating system which is shut down can freeze in the event of frost and may suffer damage.
• Drain the heating system that is shut down if there is danger of frost.
If solar heating support is not required for water heating for an extended period, the DAIKIN Solar system can switched off
temporarily at the mains switch of the DAIKIN Solar system R3 control system.
If there is a danger of frost:
– DAIKIN Solar system start the solar system in operation
or
– suitable antifreeze measures must be applied to the connected heating system and hot water storage tank (e.g. draining).
If there is a danger of frost for only a few days, the unit's excellent heat insulation ensures that the ROTEX
Sanicube does not have to be drained, provided that the storage tank temperature is monitored regularly and does
not fall below DAIKIN +3°C. This does not, however, provide any protection against frost for the connected
heat distribution system!
Draining the storage tank
• Switch off the main switch and secure against restarting.
•:
– Use the hose connection to connect a hose to the solar return flow with the boiler filling and draining valve.
– Drain the tank's water content.
•:
– Follow the instructions on shutdown provided in the operating and installation instructions EKSR3PA + EKSRDS1A.
4.2.2Final shutdown
• Decommissioning a Solar system (see section 4.2).
• Solar system disconnected from all electrical and water connections.
• Dismantle the Solar system in accordance with the instruction manual (chapter 3 "Installation") in reverse order.
• Solar system disposed off in a professional manner.
Recommendations for disposal
The DAIKIN Solar system has an environmentally friendly design. During the disposal process, the only waste created is that
which can be used for material or thermal recycling.
The materials used that are suitable for recycling can be sorted into individual types.

5.1Wind loads
5.1.1Information about wind loads
When installing the solar panel, the European regulations of technology must be observed.
In particular, for flat roof installation, the regulations concerning the harmonised standard EN 1991: Effects on Supporting Structures.
In Germany, DIN 1055 is the most important standard for load supporting on structures and, in the construction industry, it is
the most recognised technological regulation. DIN 1055 provides precise stipulations how you must determine loads for various
different buildings and locations. Requirement of wind and snow loads can thus be determined to the specific local requirements.
The DAIKIN Solar system fixing system corresponds to the requirements of DIN 1055 or EN 1991.
5.1.2Effects of wind on the structures
The wind load on the flat roof frame depends on the individual erection site. Wind acts in a suction or pressure on the solar panels
and the supporting structure. The wind load depends mainly on the wind zone, the consistency of the landscape and the height
of buildings.

The specialist technician is obligated to observe and maintain the applicable standards in the installation of
solar panels with supporting structures.

The design must take account of the wind loads in accordance with the country-specific regulations and guidelines. The minimum
distances to the edge of the roof must also be maintained, because in corners (A) and on edges (B) of rooves considerably higher
wind loads arise. The minimum distance of 1 m must be maintained.
Fig. 5-1Minimum distances to corner and edge areas
5.1.3Selection of fixing type
DAIKIN solar panels must be secured against wind load when installing on flat rooves. The DAIKIN flat solar panel frame can be
installed free-standing (e.g. on concrete panels) or on a fixed support structure.
DAIKIN has designed for securing by concrete blocks. In free-standing installations, you need to secure the
solar panel frame from sliding, tipping and lifting using additional weights.
Free-standing installation with weighing-down weights
Free-standing installation with weighing down weights prevents tipping, sliding or lifting of the structure. To do this, in
accordance with tab. 5-2, insert and position the corresponding number of concrete blocks in the retainers provided.

Mounting the frame on the support structure
Installation can also be made using a separate support structure using an adequate bolted connection system. The bolted connections to the support structure must be immediately next to the force application points on the basic rails.
The responsibility for dimensioning and execution of the bolted connections is exclusively with the installation
company.

5.1.4Required anchorage weights and concrete slab thicknesses for approved wind load zones
(in accordance with DIN 1055-4: 2005-03)
The details given in this instruction manual concerning stability and resilience of the design with regard to wind speeds which
may arise are based on the static calculations of the frame in accordance with DIN 1055. With correct installation and compliance
with all relevant points in this instruction manual, the ROTEX flat roof frames are designed for wind loads up to DAIKIN
1.3 kN/m². This corresponds to a wind speed of 164km/h.
In tab. 5-1 you can read off the wind speeds in the corresponding wind zones and building heights.
• Always test the load capacity of the roof.
• If the location differs from the specified wind protection zone and the building height is above 25 m, check the anchorage of
the trestle, in addition, verifications are necessary in individual cases if applicable

5.2Snow loads
5.2.1Information concerning snow loads
Snow represents an additional weight on the solar panels. The snow load also depends on the erection location. When planning
a solar installation, you must also bear in mind the snow load that arises. The design must take account of the snow loads in
accordance with the country-specific regulations and guidelines.
5.2.2Instructions concerning snow load zones
The statistical safety of the roof construction must be guaranteed, especially with elevated snow loading.

5.3Shading
Tab. 5-4Max. permissible snow loads for flat solar panels for flat roof installation
For structural locations outside the permissible deployment limits, individual static calculations are required.
In order to prevent undesirable shading of the solar panels the installation of multiple solar panel arrays one after the other must
be undertaken at a specific separation distance (z).

Height of solar panel h for EKSV26P = 2000 mm
Height of solar panel h for EKSH26P = 1300 mm
5.4Sensor position solar panel
After installation and positioning the solar panel you need to check whether the shading and possible snow gathering on the solar
panel has an influence on the measurement made by the solar panel temperature sensor.

CAUTION!
If part of the solar panel (at the height of the return flow) is covered by snow or ice for an extended period,
frost damage may arise on the DAIKIN Drain-Back solar system.
• Check the frost protection parameters on the solar regulator and adapt if necessary.
• For parameter settings see the instructions in the control and pump unit EKSRPS3.
In the Drain-Back system, as opposed to the pressurised system, the flat solar panels are installed rotated
through 180°.
This produces the following mounting positions for the solar panel temperature sensor:
– at the bottom edge of solar panel
– at the top edge of solar panel
