    3. Information / Pipework examples Notes Ideally, the collectors should be oriented between south-east and south-west (optimum: south). Please refer to our technical advisors in case of an alternative orientation. Trees, neighbouring structures, chimneys, etc. should throw as little shade over the collectors as possible. Observe the different position of the sun (summer/winter).
  • Page 6: Information Regarding The System Hydraulics / Expansion Vessels

    4. System hydraulics expansion vessels Information regarding the The collectors can be operated with a high specific throughput (so-called High- system hydraulics Flow). Advantages: The collector is well cooled = high collector efficiency level, low heat losses at the flow line. Disadvantages: High pressure drop = powerful pump, large pipe cross-sections. Throughput: High-Flow (90 l/h x coll), ANRO (45/55) 20 °C Solar line Solar Expansion Collector Pump length line Cylinder number assembly vessel 2.5 bar Ø...

  • Page 41: Operation / Service

    20. Operation / Service Mode - A vapour film can occur particularly in the early hours of the morning due to the temperature differential between the outside air and the collector. It will disappear as the collector heats up. Where possible avoid switching off the power during solar irradiation. If vapour forms during very high solar yield, the system starts again automatically after it has cooled down.
