Caution.
Risk of damage to the collectors as a res-
ult of improper installation.
If the hydraulic connections are not installed
properly, the stainless steel tubes inside the
collector may become damaged.
▶
When tightening the clamping ring con-
nection, hold a second spanner against it.
1.
Connect the collector flow and return to the system us-
ing the connection pipework.
2.
To do this, connect the clamping ring connection (from
the
VTK
installation set (basic set)) to the collector.
3.
Connect the clamping ring connection with the connec-
tion pipework.
4.
Check the connections for tightness.
Condition
: System with collector temperature sensor
▶
Insert the collector temperature sensor into the opening
provided on the collector flow side ("hot side").
Note
In general, the collector temperature sensor
can be attached to the right or left side of the
collector field because the collectors on both
sides have a corresponding opening.

Troubleshooting
8.1
Replacing defective components
8.1.1
Procuring spare parts
The original components of the product were also certified
by the manufacturer as part of the declaration of conformity.
If you use other, non-certified or unauthorised parts during
maintenance or repair work, this may void the conformity of
the product and it will therefore no longer comply with the
applicable standards.
We strongly recommend that you use original spare parts
from the manufacturer as this guarantees fault-free and safe
operation of the product. To receive information about the
available original spare parts, contact the contact address
provided on the back page of these instructions.
▶
If you require spare parts for maintenance or repair
work, use only the spare parts that are permitted for the
product.
8.1.2
Replace leaking collectors
Danger!
Risk of burns and scalding!
In the event of solar radiation inside the units,
collectors can reach 300 °C.
▶
Avoid working in direct sunlight.
▶
Cover the collectors before starting work.
▶
You should preferably perform the work in
the morning.
▶
Wear suitable safety gloves.
