Fig. 5.21 Fitting the hydraulic connections
• For systems with collector sensors: Plug
the collector sensor into the opening provi-
ded on the flow side of the collector (hot
side).
With several rows of collectors:
• Connect the rows of collectors in accor-
dance with the interconnection schemes
(cf. Section 4.4).
h
Note
In general it is possible to attach the
collector sensor to the left or the
right side of the collector array, as
the collectors have a corresponding
opening on each side.
Ensure VR11 sensors are fitted to the
hot side of the collector array.
a
Caution!
Danger of damage to the collector as
a result of incorrect assembly!
To prevent damage when tightening
the compression fitting, always use a
second spanner to provide a counter
force.
• Connect the collector supply and return to
the system with the connection pipes.
• To do this, connect the compression fitting
(from the VTK basic module connecting kit,
Part No. 0020076785) to the collector and
connect this to the connecting pipe.
• If necessary check all connections for
leaks.

Fig. 5.22 Insulating the hydraulic connections
After commissioning:
• Insulate the hydraulic connections with the
Armeflex insulation (1) (from the VTK ex-
pansion module connecting kit, Part No.
0020076779).
• Cover the insulation with the cover clip (2)
(from the VTK expansion module connec-
ting kit, Part No. 0020076779).
• Insulate the hydraulic system connections
with the EPDM insulation (3) (from the VTK
expansion module connecting kit, Part No.
0020076779).
