Tips:
For
every
inch,
stop
and
press
FIRMLY
on
the
O
‐
ring
into
the
channel.
You
will
see
that
the
O
‐
ring
likes
to
pop
out
around
the
dips
around
the
screws.
Take
extra
time
in
these
areas
to
insure
you
are
pressing
the
O
‐
ring
firmly
into
the
channel.

Install
Next
is
the
most
difficult
step
and
requires
the
most
patience.
Please
read
completely
and
carefully
before
attempting.
See

Dry
Hands
are
needed.
You
may
need
to
keep
a
towel
handy
to
keep
your
hands
dry
throughout
the
process.
Remove
the
center
frame
from
the
box.
Each
side
of
the
center
frame
has
an
O
‐
ring
that
needs
to
be
installed.
Lay
the
frame
down
on
your
flat
surface
and
start
the
O
‐
ring
in
one
corner
of
the
frame.
Begin
feeding
it
and
pressing
it
into
the
groove
of
the
frame.
Take
your
time,
if
you
go
too
fast
the
O
‐
Ring
WILL
pop
out.
As
you
do
this,
you
will
need
to
stretch
the
O
‐
ring
and
push
it
into
the
channel
a
little
each
¼
inch.
If
you
get
all
the
way
around
the
frame
and
your
O
‐
ring
is
short
you
did
not
stretch
the
O
‐
ring
enough
when
installing.
Start
Over.
Once
one
side
is
complete,
flip
over
frame
and
set
on
flat
surface.
(This
will
help
keep
the
O
‐
ring
in
place
while
you
install
the
next
one.)
Repeat.
Frame
to

Port
Back
Once
both
sides
of
the
frame
have
O
‐
rings
installed,
the
frame
can
now
be
attached
to
the
pump
housing.
Place
the
frame
so
it
is
flush
on
the
edges
and
the
holes
line
up
for
the
through
screws.
Double
check
that
the
O
‐
rings
are
still
in
place
and
are
not
visible.
