5.2.3 Installing hydraulic connections
Caution.
Lack of tightness due to incorrect ac-
cessories.
Incorrect accessories may result in lack
of tightness of the solar circuit and cause
material damage.
▶
Only work in the solar circuit with hard
soldered connections, flat seals, com-
pression fittings or press fittings which
have been approved by the manufac-
turer for use in solar circuits and at cor-
respondingly high temperatures.
Caution.
Risk of damage to the collectors as a
result of improper installation.
If the hydraulic connections are not in-
stalled 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
with the connection tubes.
2. To do this, connect the clamping ring connection (from
the installation set
VTK
basic set, article number
0020076776) to the collector.
3. Connect the clamping ring connection with the connec-
tion pipework.
4. Check the connections for tightness.
Conditions
: System with collector sensor
▶
Insert the collector sensor into the opening provided on
the collector flow side ("hot side").
Note
In general, the collector sensor can be at-
tached to the right or left side of the col-
lector field because the collectors on both
sides have a corresponding opening.
