17 MSL 72.140 Jetsam/Explorer R.1
Those that are installing the elbow themselves, should first apply Teflon tape to the threads. While this is not
a pressure fitting and tape really isn’t required, it will help protect the threads. When attaching the elbow, en-
sure that it is not cross threaded. Also, do not over tighten. It is not required. Four to five turns is enough.
The best tool to tighten the elbow is a 5/8 wrench. Use it to cup the bottom of the elbow to help turn it into
position. You should only need the wrench on the last turn. The first few turns can be done by hand.
*NOTE:
The
right
and
left
side
elbows,
which
attach
to
the
rebreather
head,
are
NPT
or
pipe
thread.
This
is
a
tapered
thread,
NOT
a
straight
thread.
If
you
screw
a
fitting
with
a
straight
thread,
such
as
a
swivel
elbow,
into
this
port
it
will
damage
the
rebreather
head!
If
this
hap-
pens,
it
is
NOT
repairable.
Prior
to
modifying
your
rebreather,
please
be
certain
that
you
un-
derstand
what
fittings
are
required.
*NOTE:
See
the
Classic
KISS
manual
for
instructions
on
disassembling
and
servicing
the
gas
addition
valves.
*NOTE:
Remember,
when
attaching
the
gas
addition
valve
to
the
hoses
or
other
fittings,
al-
ways
put
one
wrench
on
the
fitting
which
attaches
to
the
plastic
valve.
Use
this
wrench
to
ensure
that
this
fitting
does
not
spin
while
you
are
either
attaching
or
removing
the
valve
from
other
fittings
or
hoses.
If
you
need
to
remove
or
attach
any
fittings
which
go
directly
into
the
plastic,
be
careful
to
not
over
tighten.
Use
only
two
fingers
on
the
wrench!
The hoses for the left side gas addition valve are both Miflex hoses which are rated for oxygen use. As the Ex-
plorer has two similar gas addition valves, it is important to differentiate between them. Therefore, the right
side valve hoses which have always been for pure oxygen, remain a bright yellow colour. The new hoses will
be black.
WARNING
FOR
RIGHT
&
LEFT
SIDE
ADD
VALVES!
The
oxygen
injector,
is
a
convenience.
It
is
not
a
controller
in
any
way.
The
only
device
regu-
lating
the
oxygen
partial
pressure
is
your
brain.
The
automatic
oxygen
add
does
not
reduce
the
need
to
monitor
the
three
partial
pressure
displays.
It
only
reduces
the
number
of
times
you
have
to
press
the
oxygen
add
button.
As
with
any
rebreather,
the
displays
should
be
checked
constantly
during
the
dive.
The
oxygen
regulator
can
fail
and
stop
delivering
02
or
it
can
fail
and
increase
the
flow
drastically.
The
orifice
can
become
plugged
and
stop
deliv-
ering
oxygen.
The
add
valve
O-rings
can
fail
and
increase
the
amount
of
02
being
added
to
the
breathing
loop.
Any
of
these
things
can
kill
you
but
any
of
these
problems
can
be
over-
come
if
you
are
aware
of
the
conditions
in
the
breathing
loop.
KNOW
YOUR
PO2
AT
ALL
TIMES
!
