6.1
Preparing to install the collectors
Before beginning actual installation on the roof, fit the
end caps to the collectors on the ground to make work
on the roof easier.
To secure the end caps (and later the corrugated pipe
connectors and connecting pipes as well), attach
brackets to the connections.
6.1.1 Pipework connections
The collectors must be installed in such a way that the
sensor bushs that receive the collector sensor (Fig. 18,
Item 1) are at the top.
The pipework in the collector is designed as a double
meander, which enables you to carry out two different
pipework connections:
single-sided connection of up to 5 collectors
Up to 5 collectors can be connected one side of
a collector array (Fig. 17 and Fig. 18).
Two-way connection of up to 9 collectors
If there are more than 5 collectors installed in one
collector array, the water connection must be two-way
(Tichelmann principle, Fig. 19).
The two-way connection can also be made if there are
fewer than 6 collectors (Fig. 19).
If more than 9 collectors are required then a further AGS
pump station is required.

CAUTION!
SYSTEM DAMAGE
through leaks in the collector
connections.
The corrugated pipe connectors,
connecting pipes and collector
connections must not display any signs
of damage or contamination.
B
The collector connections have had
special grease applied in the factory
to make installation easier. Do not use
any other grease.

USER NOTE
The water connection pipes can be
connected on the right (Fig. 17) or left
(Fig. 18). In this manual, the connection
pipes are shown on the right.
