Before installation 4 Interconnection diagram Hydraulic connection preparation Note 4.5.1 On-roof mounting Observe the planning information when dimen- sioning the field volume flow. Field arrangement side by side Note If you connect 1 to 5 collectors one after another, the hydraulic connections can be laid one below the other on one side.
Besides, the height of the mounting rails is variable, in order to compensate for small floor irregularities. Collector position and field arrangement Vaillant flat collectors are available in different versions: one for horizontal position, one for vertical position. Generally, the installation steps and the instructions described in this manual are valid for both collector positions.
