Open
the
Inlet
valve
just
enough
so
you
can
hear
the
water
passing
thru
the
valve
‐
you
should
notice
a
corresponding
slow
flow
out
of
the
drain
line.
After
a
minute,
if
there
are
no
air
bubbles
present,
open
the
valve
about
another
quarter
inch
‐
again,
you
should
see
a
corresponding
increase
in
the
flow…
And
you
will
continue
until
the
valve
is
full
open.
IMPORTANT:
Any
time
that
you
are
in
the
Backwash
or
Rapid
Rinse
position,
you
may
need
to
unplug
the
power
‐
this
will
hold
the
valve
in
its
current
position,
so
it
doesn’t
‘time
out’
and
go
to
the
next
position.
When
you
plug
the
valve
back
in,
after
a
minute
it
will
return
to
where
it
was
when
you
unplugged
it
(i.e.
2:32
remaining
in
BW).
Understand,
it
is
not
possible
to
jam
media
into
the
head
while
in
Rapid
Rinse,
or
Service,
just
in
the
Backwash,
when
the
flow
direction
is
reversed.
What
you
are
trying
to
accomplish,
after
you
have
pushed
the
media
back
in
to
the
tank
in
the
Rapid
Rinse
position,
is
to
get
the
Inlet
valve
all
the
way
open
in
the
Backwash
position,
without
it
jamming
media
back
in
the
head,
and
this
is
the
part
where
you
have
to
go
slow,
open
up
the
Inlet
valve
a
little
bit
at
a
time
and
let
it
run
for
a
few
minutes
‐
this
is
why
you
may
have
to
unplug
it
‐
and
then,
once
you
have
done
that,
finally,
do
one
more
backwash,
starting
with
the
Inlet
valve
open,
just
as
it
will
be
when
it
does
it
automatically
at
night.
Once
it
does
that
successfully,
you
are
done.
