Fig. 6.15 Positioning the upper mounting rail
• Slide the upper mounting rails towards the
collectors.
• Take care that the upper parts (1) of the
clamping elements are over the rails on the
collectors.
• Tighten the clamping element with the
socket/combination wrench (13 mm AF).
a
Caution!
After tightening the clamping ele-
ments, make sure the tension is cor-
rect by shaking the upper part of the
clamping element. If it can be moved,
retighten the nut.
Fig. 6.16 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).
h
Note
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.
Always ensure the VR11 sensor is fit-
ted 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 the connections for
leaks.
