Pipework examples
Recommendation:
Air vent trap
(install at the
highest point)
Alternating pipework
(up to 10 collectors)
Piping several collector arrays in accordance with Tichelmann

Information on system hydraulics
With alternating pipework a maximum of 10 CFK-1 collectors may be
connected in parallel.
- Do not use zinc-plated/galvanized pipes, fittings, etc.
-
Thermal insulation must be temperature-resistant to >175 °C, in external
areas it must also be UV and weather-resistant.
-
Only use the gaskets supplied.
Pipes close to the collectors may reach temperatures of up to 200 °C when the
CAUTION
system is on standby. Beware of potential fire hazard.
- Pipes should be routed to the collector array with a rise. This will enable an
'emptying' of the collector in the event of stagnation. Do not create air locks.
Recommendation:
- Fit an air trap at the highest point.
- Where multiple collectors are fitted, integrate flow regulating valves into the
return to enable hydraulic balancing.
The solar lines must be laid and connected before the collector casing and
CAUTION
thermal insulation are fitted, so that the entire line length and all collector
connection points can be checked for tightness.
