MAINTENANCE
REQUIREMENTS
12.1
General
The
collector(s),
as
all
other
devices,
needs
basic
maintenance
to
ensure
constant
and
high
performance
at
all
times.
There
are
various
actions
that
can
be
done
by
the
user;
other
actions
must
be
carried
out
by
the
manufacturer’s
licensed
service
crew.
For
high
performance
and
long
service
life
of
the
entire
water
heating
‐
distribution
installation
,
maintenance
is
required
and
for
the
rest
of
installation
(boiler,
piping,
control
systems).
12.2
Regular
maintenance
by
the
user
It
is
preferred
that
the
user
checks
twice
per
year
the
place
where
the
collector(s)
is
placed
and
visually
controls
the
collector
and
the
rest
of
the
components.
More
specifically:
‐
check
the
leaks
in
collector’s
piping
and
the
leaks
in
components
‐
check
for
any
condensation
of
the
collector
‐
check
the
installation
of
the
collector
on
the
mounting
kit
and
the
screws
on
the
mounting
kit
in
order
to
find
any
loose
screws
because
of
the
wind
etc.
‐
if
for
any
reason
there
is
a
need
to
fill
the
closed
system
of
the
collector
with
water,
you
should
also
add
antifreeze
to
retain
the
ratio
according
to
table
No.
1
‐
Observe
any
probable
cracking
of
the
collector’s
glass
‐
Observe
the
clarity
of
the
glass
‐
Observe
the
condition
of
the
piping
insulation
conveying
water
from
the
collector
to
the
boiler
Cleaning
of
the
collector’s
glass,
when
required,
is
best
done
without
too
much
sun.
It
is
recommended
that
a
skilled
authorized
technician
visits
the
installation
in
all
other
cases.
In
case
of
glass
cracking,
the
glass
should
be
replaced
immediately
because
there
is
risk
of
collector
corrosion.
12.3
Maintenance
by
service
crew
every
three
years
It
is
recommended
that
the
following
controls
shall
take
place
periodically
every
three
years
by
a

team:
‐
check
glass
(cleaning,
cracking,
shading
of
collector)
‐
check
collector’s
support
on
the
mounting
kit
‐
check
water
‐
tightness
of
