Hydraulic connections
Temperature sensor
Each collector has a sleeve for inserting a temperature sensor. The sleeve is directly connected with the absorber. If the
collectors are installed correctly, the sleeve is always located on the top of the collector on the left. The temperature sensor
can be inserted in any collector. Please pay attention to the maximum insertion depth of 4 cm and secure the sensor
against slipping out. Due to the measuring point on the absorber, the temperature measured by the sensor may differ from
the fluid temperature.

In case of multi-row installations as well as installations which include the STI Drain Back System, the connection
pipe must always be connected with the diagonal line to the external manifold (Tichelmann), e. g. bottom left and
top right.

In case of installing an air eliminator, install it at the opposite end
of the top flow connection!
