3.1 Transport and storage
3.1.1 Transport
The EKSV26P/EKSH26P flat solar panels are delivered wrapped in film. As long as the solar panels are secured on a pallet which
corresponds to the size of the solar panel, then industrial trucks such as forklift trucks and stackers or cranes are suitable for
transport. Other components of the solar system are supplied packaged separately.
3.1.2 Storage
The following should be taken into account when storing solar system components:
• All components should be stored in dry and frost-protected rooms only.
• Dismantled hydraulic components must be completely drained before being stored.
• Components must not be stored until they have cooled down.
• Current-carrying components must be perman ently isolated from th e power supply before storage (switc h off fuses and main
switches, remove cables) and must be secured against inadvertent restarting.
• The components must be stored in such a way that persons are not endangered by them.
CAUTION!
The EKSV26P/EKSH26P flat solar panels are impervious to slight mechanical loading. However, impact, shock
and walking on them should be avoided.
• The EKSV26P/EKSH26P flat solar panels should be transported and stored carefully in their original
packing only and this packing should not be removed until shortly before installation.
• The EKSV26P/EKSH26P flat solar panels should be stored and transported flat on even and dry supports.
– Transport with forklift trucks or cranes is only allowed if on pallets.
– Up to 10 flat solar panels can be stacked and transported on top of each other.
The regulations in the respective documentation fo r other heating c omponents apply for transport and storage of the se products.
3.2 System concepts
Solar systems are usually set up according to one of the following system layouts. This also includes the possibility of connection
on the opposite side of the flat solar panels in each case.
Connection at opposite ends possible1) (possible from 1+ solar panels) Same-side installation connection (up to maximum of 3 solar panels)

3 x Installation
The EKSV26P/EKSH26P flat solar panels can be installed on flat roofs. Further information can be found in the
installation instructions for the solar panel flat roof support frame.
The flat solar panel EKSV26P can be integrated into the roof surface. You will find further information in the
solar panel in-roof installation instructions.
Installation instructions concerning differences between unpressurized and pressurized system
Unpressurized system (Drain Back) Pressurized 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).
No particular minimum gradient of the solar panel array is
required. A gradient from the lower (return flow) connection
should however be avoided.
With a same side panel connection (max. of up to 3 solar
panels allowed) the panels must be aligned with their lower
edge precisely horizontal.
The connection pipe must be set up with a continuous gradient
of at least 2% and without any counter gradient.
Tab.3-1 Installation instructions
3.3 Laying connection pipes
3.3.1 Unpressurized System
The connection pipe between the solar panel array and the hot
water storage tank must be made of pressure-resistant metal
piping (recommended Cu Ø22 mm). Using plastic piping is not
allowed.
CAUTION!
Siphon action may never be allowed to occur anywhere in the pipe run between storage cylinder and the flat
solar panel. This could lead to functional faults and even material damage.
• Always make sure that pipe runs have a continuous gradient of at least 2%.
CAUTION!
In the case of longer 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:
• The pipes should either be fixed to a rigid auxiliary structure (e.g. a profi le rail, pipe etc.) or the pipe should
be run alongside a drainage pipe having a gradient (e.g. HT pipe).
• Lay prefabricated connection pipes (fee d and return flow) with integrated sen sor cable (see Chapter2 "Product description“)

between the planned installation site of the solar panel array in the inner roof and the installation site of the hot water
storage tank with the EKSRPS3 pump unit.
– Make sure there is adequate length for connection to the hot water storage tank and the flat solar panels.
– The maximum permissible overall pipe length must not be exceeded (see Tab.3-2).

Additional notes about connecting pipes
If on-site conditions make it impossible or very d ifficult to install the connecting pipe s in the manner described above, slig ht deviations from the specified installation are permitted. Hereby, the inflow pipe may not be larger than 18x 1 mm.
1. If vertical copper pipes are already installed in the house, they c an be used if a continuous connection pipe gradient can be
guaranteed.
2. If a uniform gradient from the second roof penetration to all pipe sections can not be gua ranteed whe n the solar pa nels 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 cylinder mounting floor level,
– the internal diameter of the inflow pipe is not more than 13mm,.
– 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 pip e s ho uld be us ed 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.
3.3.2 Pressurized system
The connection pipe between the solar panel array and the hot water storage tank must be made of pressure-resistant metal
piping (recommended Cu Ø22 mm). Using plastic piping is not allowed.
For the roof penetration DAIKIN recommends laying the connection pipes through ventilation tiles to the inside of the roof.

3.4 Installing the solar panel components
DANGER!
There is an increased accident risk during work on a 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 Preve ntion 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 starting the installation work, ch eck that the roof structure has adequate carry ing c apa city and
is undamaged. (e.g. defective laths or leaks in the roof.).
WARNING!
After their packaging is removed, the flat solar panels will become hot very qu ickly if they are exposed to the
sun's rays.
• Wear protective gloves.
• Remove protective caps (not heat-resistant) after positioning the flat solar panel.
• Do not remove the protective covering of the glass on the solar panel until leak testing has been
completed.
3 x Installation
CAUTION!
Frost or overheating can damage the system.
• Permit the system to drain. Make sure that th e flat s olar p anels a re i nstalle d so that thei r lowe r edge is
always higher than the inflow coupling of the Solaris storage cylinder.
Unless specified otherwise, the installation steps quoted for tiled roofs are the same for other roof coverings.
Notes for safe and trouble-free operation
• Mount the solar panel array with a gradient to the lower collector coupling (return flow).
• For flat solar panel arrays with connections on same side (up to 3 solar panels permitted), the lower edges of all the solar
panels must be absolutely horizontal. However, we recommend always making the connections at opposite ends.
• Always run the connection pipe between the flat solar pan els and the s torage with contin uous gap to avoid a s iphon effe ct
(two-way gap) over the whole connection passage.
• The upper edge of the flat solar panels may not be more than 12m above the storage cylinder(s) mounting floor level.
3.4.1 Installing the supporting structure for subsequent installation on the roof

12. Adjust the height of the mounting profile rail (Fig3-10 to Fig3-11).
– With connections on both sides (always recommended), align the mounting profile rail with a slight gradient to the
return flow connection (water feed to the lower solar panel connection). A negative gradient should be avoided at all
costs.
– With same-side connection (up to 3 solar panels) the mounting prof ile rail must be aligned exactly horizontally. How-
ever, we recommend always placing the connection on opposite sides (ensures automatic venting of the solar panel or
draining of the solar panels in the event of a pump standstill).

3.4.3 Installing the supporting structure for subsequent in-roof installation
Further information is included in the operating instructions "In-roof mounting of solar panels". It is supplied with the basic inroof mounting package.
3.4.4 Installing the first flat solarpanel
1. Fit solar panel securing ties vertical to the solar panel support surface, at the distance specified for the type of solar pane l
into the guiding groove of the lower mounting profile and tilt downwards. After they have been hooked on, the solar panel
securing clips can be moved sideways (see Fig 3-15 and Fig 3-16).
2. Lift the flat solar panel onto the roof area using a crane. If no crane is available, the solar panel can be hoisted onto the roof
with a rope, using a ladder leaning against the roof edge. Depe nding on the installation re quirements, unpack the sol ar panel
before or after the transport to the roof and remove the collection pipe protective plugs.
WARNING!
Danger of burns from hot solar panel couplings and hot solar panel frame.
• Do not touch hot parts.
• Wear protective gloves.
The flat solar panel must be lifted onto the roof i n th e co rrect o rien tation fo r mounting ( preve nts faul ts during
connection or difficult manoeuvring operations). The top side of the solar panel is marked on the protective
cover of the solar panel glazing. The plugs for the solar panel temperature sensor and the round solar panel

7. Carefully slide the next flat solar panel up to the last mounted flat solar panel. Make sure that the expansion joints slide
cleanly into the connection pipes of the flat solar panel.
8. Slide the next flat solar panel further up to the stop against the last mounted flat solar panel (Fig3-26). You should be able
to hear the retaining clamps click in place. The distance between the flat solar panels is determined automatically by the
length of the expansion joints with mounting supports fitted.
CAUTION!
If the retaining brackets do not click in place audibly, the solar system can develop leaks and thus restrict
operational safety.
Reasons for the retaining clamps not engaging:
– Flat solar panels not completely pushed up together.
– Absorber position moved (push the absorber into the conne ctions on the oppo site sid e in the correct pos i-
tion, wearing protective gloves).
CAUTION!
If the connections on the flat solarpanel (EKSFIXVBP) are not fitted with extreme caution, the seal ring can
get damaged. This causes leaks in the system.
• Always fit the expansion joints to the flat solar panels with extreme caution.
• Bring the next flat solar panel in alignment with the connection pipes of the previo us flat solar panel when
pushing together.

3.4.6 Hydraulic connection of the flat solar panel (unpressurized system)
CAUTION!
Thermal expansion of the plastic pipes in the connection pipe over extended horizontal sections with only a
slight gradient can lead to the formation of pools of water.
Pools of water between the fixing points prevent draining of the system. This me ans frost safety is no longer
ensured.
• The pipes should either be fixed to a rigid auxiliary structure (e.g. a profile rail, pipe etc.,) of the pipe
should be run alongside a drainage pipe having a gradient (e.g. HT pipe).
CAUTION!
Siphon action may never be allowed to occur anywhere in the pipe run betwe en storag e cylind er and the flat
solar panel. This could lead to functional faults and even material damage.
• Always make sure that pipe runs have a continuous gradient of at least 2%.
If the connecting pipe of EKSCON15 or EKSCON20 is not long enough to bridge the distance between the storage cylinder and
the solar panel array, it can be lengthened depending on the size of the solar panel array.
Extension kits EKSCONX25 (2.5 m), EKSCONX50 (5m) and EKSCONX100 (10m) are available.
Take account of the instructions concerning lengths of pipe in Tab.3-2, Page11.
Instructions on pipe installation
1. Run the connecting pipe with a continuous gradient between the flat solar panels and the storage cylinder.
2. Connect the solar panel array at opposite ends and set it up so that the return flow coupling (at the bottom) is located at
the lowest point of the solar panel array (installation layouts Chapter 3.2Page10).
The different connection points and dimensions of the inflow connection pipe (at the top of the solar panel
Ø 15 mm) and the return flow connection pipe (at the bottom of the solar panel Ø18 mm) make it impossible
to confuse one pipe with the other.
• However, you must ensure that the infl ow and return flow pipes on the flat solar panel are lab elled as heat
generators.
3. Remove three roof tiles at each intended roof penetration point (one or two tile rows be low the solar panel connec tion pipes).
4. Lay the connection pipes up to the roof penetration and fix in position (e.g. with clamps).
5. Carefully open the thermal roof insulation under the penetration point, so that the return flow pipe (Ø18 mm) can be pulled
out and can be laid with sufficient gradient to the roof penetration.
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.
6. Run the connecting pipes through the roof at the points provided. To ensure uninterrupted thermal insulation (also within

cable and the solar panel temperature sensor cable through the respective M16 glands from inside (Fig3-30).
9. Cover the roof penetrations (Fig 3-31).
– The roof tiles at the side and above must overlap the roof penetration.
– The corrugated flashing must overlap the roof tile underneath and be shaped to match the roof tile.
CAUTION!
With special roof coverings, such as roof ti les with very pron ounced u ndulations (large differ ences in height),
sealing problems can occur with the universal roof penetration box.
• In such cases, and also with plane tiles or slate roofing, a professional roofer should be consulted.

3.4.7 Hydraulic 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 being scalded if you use the wrong connection pipes.
• The connection pipe between the solar panel array and the hot water storage tank must be made of
pressure-resistant metal piping (recommended Cu Ø22 mm).
• Using plastic piping is not allowed.
The connection fittings include d in the connection kit EKSRCP have compression ring joints for copp er piping Ø22 mm. Therefore
we recommend also using copper piping with a Ø22 mm as the connection pipe between the solar panel array and the h ot water
storage tank.
Commercially available ventilation tiles for roofing are suitable for the connection pipes penetrating the roof.

– included in the EKSCONRVP kit and
– in the EKSCONLCP kit.
3.4.9 Installing the solar panel temperature sensor
CAUTION!
Connection pipes will not dissipate voltages induced by electrical storms. Under adverse circumstan ces, these
voltages can extend through the solar panel sensor up to the control and thus damage both.
• Generate equipotential bonding ("Earthing") between foundation and solar panel array.
This should only be performed by an authorised special ist (electrician) in accordance with the local regulations.
The mounting openings for the solar pan el temperature sensor are located to the le ft a nd righ t at the top of the side solar panel
frame, approx. 10 cm below the upper connection. The mounting openings ar e fitted with plugs in the a s-delivered condition. Fi t
the solar panel temperature sensor at the position where the feed pipe is connected.
1. Remove the sensor plugs (Fig 3-46).
2. Push solar panel temperature sensor up to the stop in the flat solar panel (Fig3-47). 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 mounting rail or
connecting pipe by means of cable ties (Fig3-48).
CAUTION!
Moisture can damage the temperature sensor.
• When securing the cable, make sure that no rainwater can run down the cable to the sensor.

must first be released as follows:
1. Press the retaining clamps out of the
engagement positions and pull off
(Fig 3-49 and Fig 3-50).
2. Pull off the connection elbows

4 Start-up and taking out of service
4.1 Start-up
The instructions for integrating the hydraulic system, start-up, operating the control systems and rectifying faults and malfunctions are contained in the operating and installation instructions of the control system and pump unit ( EKSRPS3 or
EKSR3PA + EKSRDS1A).
4.2 Taking out of service
4.2.1 Temporary shutdown
If solar heating support is not required for water heat ing for an extended period, the so lar system can be switched off tempora rily
at the mains switch of the solar control system.
If there is a danger of frost:
– the solar system must be started up again
or
– suitable antifreeze measures must be applied to the co nnected heating system and hot water storage tank (e.g. draining ).
4 x Start-up and taking out of service
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 there is a danger of frost for just a few days , the unit's excellent h eat insulation means that the water storage
tank does not have to be drained, provi ded that the storage tank temperature is monitored regularly and does not
fall below+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.
•:
– Connect a hose to the solar return flow with the boiler filling and draining valve using the hose connection.
– Drain the tank's water content.
•:
– Follow the instructions on shutdown prov ided in the operating and installation instructions EKSR3PA + EKSRDS1A.
Recommendations for disposal
The DAIKIN solar system is constructed in an environme ntally friendly way. During the disposal proces s, the only waste produced
is that which can be used for material or thermal recycling.
The materials that are suitable for recycling can be separated so that they are unmixed.
Through the environmentally friendly de sign of the solar system, DAIKIN has compl ied with requirements for environmentally sound disposal. Proper disposal in complian ce with the applicable national regulations of the country
of use is the responsibility of the user/owner.
