Installing Flat Solar Panel - Daikin EKSV21P Installation Manual

3 x Installation
16. Install the upper mounting profile rail at a distance of Y
the same as the lower mounting profile rail). Make sure that the upper mounting profile rail forms a flat parallel area for
supporting the flat solar panels in connection with the lower mounting profile rail and the height adjustment.

3.4.3 1. Installing flat solar panel

1. Fit solar panel securing ties vertical
to the solar panel support surface, at
the distance specified for the type of
solar panel 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. 3-16 and fig. 3-17).
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. Depending on the installation requirements, unpack the solar panel
before or after the transport to the roof and remove the collection pipe protective plugs.
3. Turn the flat solar panel into the
individual mounting position in
accordance with the planned
installation system, as depicted on
the covering film (fig. 3-18).
4. Position the flat solar panel above
the mounting rails as shown in
fig. 3-19, and carefully lower it into
the securing hooks.

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).
• Align both mounting profile rails exactly flat and parallel to each other. 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 of the solar panel temperature sensor is only supported from version 4.2
on the R3 control system.
