LUBRICATION
The
only
point
of
the
penstock
which
requires
lubrication
is
the
turning
point,
which
we
recommend
greasing
about
twice
a
year.
After
the
maintenance
and
in
an
ATEX
zone,
you
must
check
the
electrical
continuity
between
the
pipe
and
the
rest
of
the
valve’s
components,
such
as
the
body,
flap,
stem,
etc.

STORAGE
To
ensure
the
penstock
is
in
optimum
conditions
of
use
after
long
periods
of
storage,
we
recommend
storing
it
in
a
well
‐
ventilated
place
at
temperatures
below
30
º
C.
It
is
not
advisable,
but,
if
stored
outside,
the
penstock
must
be
covered
to
protect
it
from
heat
and
direct
sunlight,
with
good
ventilation
to
prevent
humidity.
The
following
aspects
must
be
considered
for
storage
purposes:
The
storage
place
must
be
dry
and
under
cover.
It
is
not
recommended
to
store
the
equipment
outdoors
with
direct
exposure
to
adverse
weather
conditions,
such
as
rain,
wind,
etc.
Even
when
the
equipment
is
packaged.
This
recommendation
is
even
more
important
in
areas
with
high
humidity
and
saline
environments.
Wind
can
carry
dust
and
particles
which
can
come
into
contact
with
the
penstock’s
moving
parts
and
this
can
lead
to
operating
difficulties.
The
equipment
must
be
stored
on
a
flat
surface
to
avoid
loss
of
shape.
If
the
equipment
is
stored
without
suitable
packaging
it
is
important
to
keep
the
penstock’s
moving
parts
greased,
for
this
reason
it
is
recommended
to
carry
out
regular
checks
and
lubrication.
Likewise,
if
there
are
any
machined
surfaces
without
surface
protection
it
is
important
for
some
form
of
protection
to
be
applied
to
prevent
the
appearance
of
corrosion.
