3.2 System 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 systems ( +).
3.3 Laying connection pipes
Installation instructions concerning differences between unpressurised and pressurized system
Fig. 3-2 Installation instructions
For Solar panels on-roof installation of the flat solar panels, the roof surface must be inclined at an angle of
15° to 80°.
The flat solar panels EKSV26P and EKSH26P can be installed on flat roofs. Further information can be found
in the installation instructions for the DAIKIN Solar system flat roof framework.
The flat solar panels EKSV21P and EKSV26P can be integrated into the roof surface. Further information can
be taken from the DAIKIN Solar system in-roof installation instructions.
Fig. 3-1 Alternately connected Solar system solar panel with hot water storage
tank EKHWP* (shown in the drain-back 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.
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). Using plastic
piping is not allowed.

3.3.1 Non-pressurised System
• Lay prefabricated connection pipes (feed and return flow) with integrated sensor cable (see chapter 2 "Product description",
page 13) between the planned installation site and 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. 3-1).
Tab. 3-1 Maximum 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 devia-
tions 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.
2. If a uniform gradient from the second roof penetration to all pipe sections can not 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 cylinder 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.
3.3.2 Pressurised 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). Plastic pipes must not be used.
For the roof breakthrough DAIKIN recommends routing the connecting pipes through a ventilation tile to the inside of the roof.
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.

3.4 Mounting flat solar panels
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 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 must not be more than 12 m above the storage cylinder(s) mounting floor level.
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.
• Ensure that, during installation, the bottom edges of the assembled flat solar panels are above the Solar
system flow connection on the storage tank.
