Place
the
Euthanex
Lid
on
the
cage.
To
properly
make
the
connection,
pull
back
the
coupler
and
slide
it
over
the
male
stem.
The
coupler
will
snap
back
into
place
and
secure
the
connection.
The
system
is
ready
for
operation.
Set
for
20
PSI
out.
5.
Attach
the
heated
regulator
to
the
CO
2
tank.
It
is
recommended
that
Teflon
tape
be
used
on
the
CO
2
tank
threads
before
attaching
regulator.
Use
a
wrench
to
tighten
the
mounted
regulator.
Set
for
20
PSI
out.
We
recommend
setting
the
incoming
pressure
to
20
PSI
but
do
not
exceed
35
PSI.
The
unit
will
work
on
low
incoming
pressure
but
may
result
in
the
inability
to
achieve
higher
output
flow
rates.
Note:
The
EA
‐
550
Electrically
Heated
Regulator
is
recommended
to
operate
the
system.
Using
a
non
‐
heated
regulator
will
likely
result
in
frozen
CO
2
lines.
Setup
is
now
complete.
