Checking the Brine Level in the Brine system
The
Brine
system
must
be
filled
with
the
corr
ect
volume
of
brine.
Otherwise
the
heat
pump
unit
risks
being
damaged.
Brine
system
liquid
(brine)
must
be
added
if
the
brine
level
gets
so
low
that
it
is
no
longer
visible
in
the
expansion
vessel.
During
the
first
month
of
operation
the
brine
level
might
sink
a
little,
which
is
quite normal.
The
brine
level
may
also
vary
a
bit,
depending
on
the
temperatur
e
of
the
heat
sour
ce.
Under
no
cir
cumstances,
however
,
shall
the
brine
level
be
allowed
to
sink
so
much
that
it
is
no
longer
visible
in
the
expansion
vessel.
