CMO
will
not
be
liable
if
the
penstocks
suffer
any
damage
due
to
improper
handling
or
without
proper
authorisation.
The
penstocks
must
not
be
modified
except
under
express
authorisation
from
CMO.
The
following
instructions
should
be
followed
in
order
to
avoid
personal
injury
or
material
damage
when
carrying
out
maintenance
tasks:
The
staff
responsible
for
the
maintenance
or
operation
of
the
equipment
must
be
qualified
and
trained.
Use
suitable
Personal
Protective
Equipment
(PPE)
(gloves,
safety
boots,
goggles,
etc.).
Shut
off
all
lines
which
affect
the
penstock
and
put
up
a
warning
sign
to
inform
about
the
work
being
carried
out.
Completely
isolate
the
penstock
from
the
whole
process.
Empty
the
conduit
or
line.
Drain
all
the
fluid
from
the
conduit
or
line
through
the
penstock.
Use
non
‐
electrical
hand
tools
during
maintenance,
in
accordance
with
EN13463
‐
1
(15
).
The
only
maintenance
required
in
this
type
of
penstocks
is
to
change
the
rubber
sealing
joint.
It
is
recommended
to
check
the
seal
regularly
every
6
months,
although
the
working
life
of
the
seals
will
depend
on
the
operating
conditions
of
the
penstock,
such
as:
pressure,
temperature,
number
of
operations,
type
of
fluid
and
others.
These
joints
are
bolted
with
flanges;
both
the
flanges
and
the
bolts
are
made
of
stainless
steel,
and
can
be
reused
several
times.
In
an
ATEX
zone,
electrostatic
charges
may
be
present
inside
the
penstock,
which
can
cause
a
risk
of
explosion.
The
user
will
be
responsible
for
carrying
out
appropriate
actions
in
order
to
minimise
the
risks.
The
maintenance
staff
must
be
informed
about
the
risks
of
explosion
and
ATEX
training
is
recommended.
Regular
cleaning
of
the
penstock
to
prevent
accumulation
of
dust.
Avoid
re
‐
painting
the
products
supplied.
IMPORTANT
SAFETY
ASPECTS
In
order
to
work
in
ideal
safety
conditions,
both
the
electrical
and
magnetic
elements
must
be
idle.
The
electrical
control
cabinets
must
also
be
out
of
service.
The
maintenance
staff
must
be
up
to
date
with
the
safety
regulations
and
work
can
only
start
under
orders
from
the
site’s
safety
staff.
The
safety
areas
must
be
clearly
marked,
avoiding
the
use
of
auxiliary
equipment
(ladders,
scaffolding,
etc.)
in
moving
parts,
in
order
to
produce
the
movement
of
the
flap.
Before
starting
maintenance
work
on
the
penstock,
secure
the
flap
in
open
position
using
more
than
one
system,
thus
ensuring
it
will
stay
in
place
in
the
event
of
failure.
Taking
into
account
the
recommendations
indicated,
the
maintenance
operations
carried
out
in
this
type
of
equipment
are
shown
