n Flushing and sealing control
The solar circuit is flushed in the normal flow direction, as
shown by the arrow on the circulation pump.
When commissioning, the solar installation must be flushed
thoroughly to remove grit, deposits and any flux residue.
Flushing time: 10 minutes
Flushing fluid: Heat transporting fluid only
The system must be tested for leaks with the heat transfer fluid when
flushing is finished.
4 Testing pressure: 3–6 bar (0.3–0.6 MPa)
4 Test time: 10-20 minutes
CAUTION
Propylene glycol leaks very easily. The pressure tests do
not guarantee that there will be no leaks when the system
is filled with propylene glycol under pressure. For this
reason, we recommend an additional leak test when the
system is filled and working.
