Mounting
NOTE:
The
packing
slip
indicates
the
serial
number
of
your
D
‐
Guard
TM
.
The
serial
number
is
also
on
a
label
on
the
side
of
the
D
‐
Guard
TM
.
Please
record
the
serial
number
on
the
front
of
this
manual.
The
installation
should
be
in
the
area
with
most
potential
to
detect
the
gas
as
quickly
as
possible.
Take
note
of
the
gas
density
as
this
will
help
in
finding
the
best
location
for
the
D
‐
Guard
TM
.
For
example,
heavier
gases
like
H
2
S
would
have
the
sensor
mounted
lower
than
for
Hydrogen
which
is
a
lighter
gas.
Securely
mount
the
unit
to
the
wall
using
wall
plugs
and
screws.
Dimensions
of
the
two
mounting
holes
on
the
D
