Operating tips

Connection of the fields of collectors
For the installation of the collectors, it is recommended to use coppers pipe with connections brazed out of copper. Not to
install isolating valves on the connection of a sensor or a field of sensor.
Insulation of external piping must be resistant to the temperatures, the ultraviolet radiation and the avian attacks.
Use only gaskets and components for high temperatures solar specific.
Flushing and filling
For safety reasons, you should only fill the collectors when there is no direct irradiation from the sun (or
cover the collectors). Pour bénéficier de la garantie capteur, il est impératif d'utiliser du Tyfocor
L à 45% (55% water and 45 % antifreeze). The solar thermal system should be filled and commissioned
within one week of installation, because heat build-up in the collector (array) can damage the flat gaskets
in empty systems. If this is not possible, the haute temperature flat gaskets should be replaced before
commissioning to prevent leakage.
Attention:
Use the solar fluid made up of 45% of Tyfocor L (propylene-1,2 glycol with corrosion inhibitors)
provided by Groupe ATLANTIC!
Note: 45 % of antifreeze Tyfocor L (55 %/water) – Freezing point : -25° C/ solidification point : -35° C
It may not be possible to completely empty collectors once they have been filled. For this reason,
collectors exposed to frost should only be filled with a water/antifreeze mixture, also for pressure and
function tests. Alternatively, the pressure test can also be carried out using compressed air and leak
detection spray.
Operating pressure
The maximum operating pressure is 10 bar.
Operating bleeding
The system must be bled:
- when commissioning the system (after filling the collectors)
- 4 weeks after commissioning
- when necessary, e.g. if there are malfunctions
Close the valves of the automatic air vent after the feeding of the installation
Warning:
Risk of scalding due to steam and hot heat transfer fluid!
Only operate the bleeding valve if the temperature of the heat transfer fluid is < 60° C .
When bleeding the system, the collectors must not be hot! Cover the collectors and, if possible, bleed the
system in the morning.
Check heat transfer fluid
The heat transfer fluid must be checked every two years with regard to its antifreeze and pH value.
- Check antifreeze using antifreeze tester and replace or refill if necessary! Target value is ca. - 25°
C.
- Check pH value with a pH indicator rod (target value approx. pH 7.5): If the limit pH value is less
than pH 7, replace the heat transfer fluid.
Maintenance of the collector
The collector or the collector array must be inspected visually, once a year, for any damage, leaks and
contamination.
If necessary, it is possible to change the glass by module of 2,5m ².
