4.2.3 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.
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.
