• Antifreeze
wilt raise
the pH of
the hydronic
solution
in a heat-
ing
system
above
the
recom-
mended
level due to the corro-
sion inhibitors
in the antifreeze.
The solution
must be treated
to
maintain
a pH within
the boiler
manufacturer's
recommended
level to avoid damage
to the heat
exchanger.
Follow
antifreeze
manufacturer's
instructions
for
details on how to adjust the pH.
• If the
system
has
leaked
for
some reason,
the water and an-
tifreeze
chemistry
will
need
to
be adjusted.
To avoid
damage
to the boiler, check
the pH and
chemistry
of the boiler
solution
and consult
the antifreeze
man-
ufacturer
for recommendations.
• It is recommended
that
a pH
reading
is taken
annually,
and
adjusted
as necessary.
Follow
antifreeze
/ inhibitor
manufac-
turer's
instructions
for details
on
how to adjust the pH.
_NOTICE: Antifreeze solutions can
breakdown
over time. Failure to
check antifreeze chemist_ including
inhibitors, periodically may result in
accelerated corrosion of boiler and
other system components. Consult
with the antifreeze manufacturer for
recommendations.
• Use of antifreeze
in any boiler
will reduce
heating
capacity
as
much as 10-20%.
This must be
taken
into
consideration
when
sizing the heating system, pumps
and expansion
tank. Consult
an-
tifreeze
manufacturer's
literature
for
specific
information
on
re-
duced capacity.
• Using
the
antifreeze
manufac-
turer's
instructions
determine
the freezing
temperature
need-
ed and use the correct
amount
of antifreeze.
Never exceed 50%
antifreeze
by volume.
• The
boiler
operating
pressure
must remain below 15 psi for an-
tifreeze
solutions
that specify
a
maximum
of 250°F (121_C).

* This product may be used to adjust the
pH level of the hydronic system, but on
occasion may not resolve the pH issue.
In these
cases it is recommended
to
flush the system and refill with untreat-
ed water and new boiler manufacturer
approved
antifreeze
suitable for Alumi-
num heat exchangers.
