4.1.1.3 Transporting collectors
1. To protect the collectors against damage, always trans-
port them when they are standing horizontally.
2. Transport the collectors to the roof using suitable aids.

clearances
In order to fit the collectors correctly, the specified clear-

▶ Ensure that the solar fluid flows through the collectors
either from left to right or from right to left.
Conditions: Number of VTK 1140/2 collectors: 1 … 7
max. 7 x VTK 1140/2
▶ Switch up to 7 VTK 1140/2 units in series (according to
the 14 m² aperture surface area).
Conditions: Parallel connection, aperture surface area: ≤ 7 m²
▶ Always connect as many collectors as possible in series,
even when several collector rows are arranged on top of
each other.
Note
Up to an aperture surface area of 7 m²
(accordingly for 3 pcs VTK 1140/2 + 1 pc
VTK 570/2), you must switch the collectors
in series.
Conditions: Parallel connection, aperture surface area: ≥ 14 m²
▶ Set up several parallel collector rows and connect these
hydraulically in parallel.
▶ Always connect as many collectors (at least 7 m²) as
