▶
Define the required rack clearances as described in the
chapter "Defining rack clearances".
Note
For each rack, you need two equal weights.
For the first collector, you therefore need four
weights. For each additional collector, you will
need an additional rack.
▶
Transport the required number of weights to the flat roof.
▶
Lay the weights in the final positions of the installation
site.
Note
The four weights for holding two racks for
a collector are very heavy. Therefore, it is
advisable to determine the final position and
orientation of the weights before screwing on
the rack and laying the weights there.
▶
Select a suitable fastening material for the weights used
(diameter: at least 10 mm).
▶
Drill a hole into the centre of each weight.
Screwing the rack onto weights
▶
Take hold of the first rack that is already secured in the
installation angle.
▶
Screw the front rack feet onto the first weight.
▶
Screw the rear rack feet onto the second weight.
◁
The first rack is installed so that it is stable.
▶
Install the second rack on the next two weights as de-
scribed above.
▶
Fit as many racks as you need to hold the collectors.

Danger!
Personal injury and material damage due
to a falling collector.
Improper fastening may cause a collector to
fall.
▶
Tighten the clamping elements.
▶
Check for proper tensioning by shaking
the clamping blocks.
▶
If a clamping block moves, tighten the nut
again.
Caution.
Damage to internal components.
The interior of the collector is ventilated
through a ventilation opening in the pipe
opening.
▶
Ensure that the ventilation opening is
clear so that the air can flow through it un-
impeded.
1.
Install the collectors on the roof as specified in the fol-
lowing sections.
Sliding on mounting rails
Note
System malfunction.
In the case of diagonal connection, to ensure that
the
auroFLOW plus
system functions correctly,
the lower mounting rail must be at an incline of
1% aligned to the lower connection (collector re-
turn). For a connection on the same side (max. 2
collectors), the mounting rail must be horizontal.
