Expansion vessel
The cor
rect connection of the expansion vessel is determined by the site management.
The pre c
harge
pressure must be adjusted before the filling of the system.
Expansion vessel pre c
harge pressure = Ok collector up to middle of expansion vessel in bar + 0.5 bar
,
but at least at 1
.0 bar
P
ressure test
Af
ter the mounting of the collector field, solar pipes, pump groups and the heat consumer
s the system
must be c
hec
ked for absolute leakproofness (e.g. compressed air at 2-3 bar for at least 2-3 hr
s.),
or with fluid (e.g. 4 bar for at least 2-3 hr
s.)
