Installation
5.1
Establishing the hydraulic connections (on-
roof installation)
Caution.
Leak caused by incorrect accessories.
Incorrect accessories may result in a leak in
the solar circuit and cause material damage.
▶
Only work in the solar circuit with hard
soldered connections, flat seals, compres-
sion fittings or press fittings which have
been approved by the manufacturer for
use in solar circuits and at correspond-
ingly high temperatures.
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.
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.
Condition
: Collector rows: 2 … 3
▶
Connect the collectors in accordance with the connec-
tion regulations (
→
Page 9).
▶
Connect the collector flow and return to the system us-
ing the connection pipework.
▶
To do this, connect the clamping ring connection (from
the
VTK
installation set (basic set)) to the collector.
▶
Connect the clamping ring connection with the connec-
tion pipework.
▶
Check the connections for tightness.

▶
Insulate the hydraulic connections using the heat insula-
tion
(1)
(from the
VTK
installation set (extension set)).
▶
Cover the heat insulation with the cover plate
(3)
(from
the
VTK
installation set (extension set)).
▶
Insulate the hydraulic system connections using the heat
insulation
(2)
(from the
VTK
installation set (extension
set)).
5.2
Establishing the hydraulic connections (flat-
roof installation)
Caution.
Leak caused by incorrect accessories.
Incorrect accessories may result in a leak in
the solar circuit and cause material damage.
