Hydraulic connection
8.2 Prepare the collector temperature sensor for connec-
tion
A temperature sensor is installed in each collector and is
accessible on the right side of the collector.
>
In regard to using the right collector temperature sensor,
note the instructions in chapter 5.2, page 11.
NOTICE: System failure through faulty
sensor lead!
>
Protect the sensor lead against possible
damage, e.g. from rodents.
>
Removing the cover.
>
Carefully pull the sensor cable out a maximum of 1 m
up to the red mark.

Fig. 56 Carefully pull out the collector temperature sensor
[1] Flow, left side: Pull out the collector sensor cable up to the
red mark, and guide it through the opening (only install the
second collector after this is done)
9 Hydraulic connection
The solar pump station instructions include information on
the routing of pipework to the collector.
NOTICE: Collector damage through
leaks!
The direct connection of rigid pipework to the
collector is not permissible.
>
Make the hydraulic connection of the collec-
tor to the pipework with flexible connector
pipes.
We recommend the use of standard air vent tiles
or aerial outlets for routing the connector pipes
below the roof.
Installing the connection pipes
>
Remove transport protection (red, blue) from the collec-
tor connections.
>
Push the plug-in connectors and connector types into the
collector connections. [1.]
>
Secure the connection pipe with a clamp, and feed it
through the roof together with the collector cable. [2.]
>
Push pipe into the 18mm compression fitting and tighten
the union. [3.]

Fig. 57 Run the connector pipes and sensor cable through the roof;
expose without insulation (in this case, same-inside connec-
tion).

Return from the storage tank (cold, blue transport protection)
Run the cable tie around the connector pipes and into the
opening in the collector profile.
