Safety
Start-up
WARNING
The valves and fittings can heat to temperatures of more
than 212° F (100° C) due to the solar fluid. Therefore,
do not flush or fill the system with the collectors heated
(intense sunshine).
Please note that hot solar fluid can leak from the
pressure relief valves in case of excessive system
pressure!
During venting hot solar fluid or vapor may escape and
cause scalding!
CAUTION
It is often the case that the solar system cannot be
completely drained after flushing. Thus, there is
risk of frost damage when flushing with water. It is
recommended to only use the solar fluid to flush and
fill the solar system.
Use “Tyfocor HTL“ solar fluid.
For commissioning flush and fill in the following sequence:
1. Flush the solar storage tank (to remove scale residues)
2. Fill the solar storage tank circuit
3. Flush and fill the solar heat exchanger
4. Flush and fill the collector field and primary solar loop
5. Flush and fill the complete solar circuit
This guarantees that dirt particles are not flushed into the
heat exchanger and that eventually absorbed heat can also
be dissipated.
IMPORTANT
Failure to follow flushing and filling sequence can lead to
heat exchanger blockage.
Observe the following safety instructions regarding the startup of the station:
