Safety instructions /
Protection against lightning
The following symbols are used in conjunction with these important instructions
concerning personal safety, as well as operational reliability.
"Safetyinstructions"areinstructionsthatmustbeobservedexactly,
to prevent injury and material losses,
e.g. The potentially very high temperatures inside the collector result
in a risk of scalding from the hot heat transfer medium.
"CAUTION"indicatestechnicalinstructionsthatyoumustobserve
to prevent material losses and equipment malfunctions.
The connection of the collector array to an existing or new lightning protection
system and the installation of equipotential bonding may only be carried out
by an authorised contractor, under consideration of local conditions and in
compliance with the following technical rules:
EN 62305 Parts 1-4 Protection against lightning
VDE 0100 Part 540 Selection and erection of electrical equipment
- earthing arrangements, protective conductors,
equipotential bonding conductors
Alignment and shading
Ideally, the collectors should be oriented between south-east and south-west
(optimum: south). Please refer to our technical advisers in case of an alternative
orientation. Trees, neighbouring structures, chimneys, etc. should throw as
little shade over the collectors as possible. Observe the different position of
the sun (summer/winter).
The distance between the upper end of the solar collector and the lower edge
of the ridge should be at least 3 roof tiles, in order to reduce wind forces and
toallowsufcientspaceforinstallation.

CAUTION

Notes on installation position

63062165_201508
Snow and wind loads
The load on the collector array is a combination of wind and snow loads which
are determined by the dimensions of the building, the roof shape and the
location. A precise calculation of the assumed loads must be carried out for
eachspecicinstallation,inlinewithEN1990(+NA)andEN1991(+NA)and
under consideration of regional regulations.
F3-1 collectors may be used for pressure and suction loads of up to
2.4 kN/m². By using the snow load extension set, the maximum permissible
pressure load may be increased to 4 kN/m².
F3-1Q / F3-Q collectors may be used for suction loads of up to 2.4 kN/m²
and pressure loads of up to 4 kN/m².
For safety reasons, the cross battens, rafters and roof tiles under the roof
hooks must not show signs of previous damage (cracking, drill holes, ageing),
else they will not withstand the loads to which they are subjected. If in doubt,
replace the battens and roof tiles in those sections.
We recommend the use of metal tiles below the roof hooks, particularly in
areas of high snowfall.
To avoid peaks in wind load we strongly recommend 1 metre minimum clearance
between the collector array and the roof edge (or ridge).
Additional loads caused by drifting snow or snow guards and by snow falling
from higher roofs should also be taken into consideration.
Inareaswheresnowloadsaresignicantwerecommendaroof-integrated
installation.

Air vent trap
(install at the
highest point)
Flow regulation valve
for multiple
collector arrays
Pipework examples Single sided pipework, to the right
(up to 5 collectors)
Single sided pipework, to the left
(up to 5 collectors)
Recommendation:
Piping several collector arrays in accordance with Tichelmann
With single-sided pipework a maximum of 5 F3-1 or F3-1Q, F3-Q collectors
may be connected in parallel.
With alternating pipework a maximum of 10 F3-1 or F3-1Q, F3-Q collectors
may be connected in parallel.
- Donotusezinc-plated/galvanizedpipes,ttings,etc.
- Thermal insulation must be temperature-resistant to >175 °C, in external
areas it must also be UV and weather-resistant.
- Only use the gaskets supplied.
Pipes close to the collectors may reach temperatures of up to 200 °C when the
systemisonstandby.Bewareofpotentialrehazard.
- Pipes should be routed to the collector array with a rise. This will enable an
'emptying' of the collector in the event of stagnation. Do not create air locks.
Recommendation:
- Fit an air trap at the highest point.
- Wheremultiplecollectorsaretted,integrateowregulatingvalvesintothe
return to enable hydraulic balancing.
The solar lines must be laid and connected before the collector casing and
thermal insulation are tted, so that the entire line length and all collector
connection points can be checked for tightness.

General preparations
- For handling and storage of the collector pile only use the packing strips
and pallets.
- Never move more than 16 collectors in a single pile and never store more than
24 collectors in a single pile.
- Never move collectors with the glass facing down.
- To prevent damage, never carry collectors by the collector connectors or
put them down on the connectors.
- Never place the collector back onto uneven surfaces.
- Store collectors only in dry places that are free of dust.
- Cover the glass side of the collectors until the collectors are commissioned.
- We recommend the use of transport handles (available as accessories).
CAUTION
Transport and storage
The following materials and tools are required for an easy and safe collector
installation:
1 x hammer
1 x tape measure
1 x pencil / chalk
2 x screwdriver / spanner SW 13
1 x wood drill approx. 5 mm (only roof integration)
1 x angle grinder with stone cutting disc
2 x open-ended spanner SW 30
1 x adjustable pliers
1 x hole saw (where the roof is already planked in)
Roof outlets for the solar lines (e.g. ventilation tile; cut to size with
an angle grinder)
Protective conduits (sensor lead, pipework)
Anti-falling protection
Crosshead bit
Required tools
Installation The installation and commissioning must only be carried out by authorised
contractors. This contractor will be responsible for the correct installation and
the commissioning.
The collector connections, even those of dry collectors, can become very hot
during the installation. Wear protective gloves as there is a risk of injury from
burns.
The collector must not be pulled onto the roof exclusively by the rivet nuts!
Do not step underneath the collector during transport. (see picture)
In case of jerky movements the rivet nuts can tear off and the collector
can fall.

• For single-sided pipework to the right, rotate the collector through 180°.
The short connectors are now to the left.
• For alternating pipework, ensure that all short connectors are facing in the
same direction.
Prior to joining the connections, check whether the collector gaskets are inside
eachtting.
Whenttingtheconnectionpieces,compensatorsandplugs,alwayscounter
hold the union nut on the collector tightly. Apply a maximum torque of 20 Nm.

The mounting rails can be extended by using mounting rail joiners.
One of the 3 screws of the mounting rail joiner set can also be used for securing
to a roof hook. For this, the U-rail remains centrally aligned; the screw can be
manoeuvred within the slot to the correct position above the hook.

Rooftop installation - Corrugated roof
- Forroofscoveredincorrugatedroongsheets,drilltheholes(Ø14)into
theroofskinrespectivelyattheapexofthesheetprole.
- Maintain the vertical clearance between the holes for the double-ended
screws to safeguard the rail clearance.
- Ensurethesecurexingonthesub-structure/rafters.Whererequired,create
an additional sub-structure on site.
- Drill the holes for securing the double-ended screws in the rafters (Ø 8.5)
before commencing the installation. Insert a suitable rawl plug in case of
concrete or brickwork sub-structures.
- The double-ended screws must be inserted to a depth of between 80 and
100 mm. Lubrication makes the insertion easier. The smooth part of the
shank acts as sealing seat for the contact gasket. It must be located in the
area of the roof skin.
- The upper mounting plates point downwards; the lower mounting plates
point upwards. If the snow load extension set is used the double ended
screwsshouldbecutoffushwiththenut,abovethemountingplate.This
ensures that the collector housing does not come to rest on the screws.
- Theroofskinissealedbylightlyandcarefullytighteningtheangednut.
CorrugatedEternitroongsheetsmayotherwisefracture.Usellerelements
(on site) where necessary.
- We recommend the use of a thread-locking compound (e.g. Marston-Domsel
585.243) to prevent moisture entering along the thread and to secure the
positionoftheangenut.
Distribute all supplied double-ended screws evenly over the width of the
