Commissioning information
Only fill and operate the collector with undiluted heat transfer medium G-LS by Tyforop.
Always observe the relevant safety datasheet issued by Tyforop.
Collectors can be damaged if they are filled from empty when they are very hot.
Therefore, never fill the solar circuit when the collectors are exposed to direct solar
irradiation or if they were under that influence quite recently. Where required, cover the
collector for at least one hour before filling to allow it to cool down.
Carry out a leak test before commissioning and completely ventilate the collector and
solar circuit. Manual pumps are unsuitable for this. This task requires a jet pump (at
least 800 W, 40 m head). The fill pressure should be 0.5 bar higher than the expansion
vessel inlet pressure.
Run the pump on pre-purge for at least 30 minutes and start/stop it several times. For
this, the heat transfer medium must flow through a fill & drain valve, fitted into the
return between the heat exchanger and the circulation pump, into a container and
from there back into the system, propelled by the jet pump.
The system is properly ventilated if no more bubbles appear in the returning medium
for a longer period of time.
Drain the heat transfer medium and recycle it through an approved recycling facility.
Separate materials of different kinds, (glass, metal, thermal insulation).

It is recommended to install an additional superposed expansion vessel with short
pipework assemblies (HWS in the attic).
