IMPORTANT
INFORMATION
DESCRIPTION
Carbon monoxide "CO"
is
a component
of
engine exhaust
It
is a colorless, tasteless, odorless, lighter than air poisonous
gas that can kill you without
any
warning. CO poisoning
is
one of
the
major safety risks associated with boating.
It
is
a
threat that must not be underestimated.
Several standards for CO have been published, expressed
in
parts per million "ppm"
and
hours
of
exposure:

A city in Califomia characterizes the effect of CO
concentration this way:

Should
not
be exposed above
this level for any period
of
time. A possible mild frontal
headache
in
two to three hours.
Even though Westerbeke
Safe-CO generators are designed
to
reduce normal levels of CO
in
the engine exhaust by
approximately 99%,
an
exhaust leak of untreated exhaust
would
be extremely
c1:mgerom.
!"'or
this
rellSOll
it
Is
extremely important
to
install a CO detector near the
generator and
to
be sure it
is
always turned on and
functioning properly. If this detector sounds, do not tum it
off,
assuming
it
is
a false signal.
You
can not taste, smell, or
otherwise detect
CO. Leave
the
detector on, tum off all
engines and generators, evacuate the boat leaving ports and
hatches open,
and
seek professional help.
As
soon
as
CO leaves the exhaust outlet, the level
is
subject
to
dilution in
the
open
air.
The closer a person is
to
the
exhaust outlet,
the
higher the concentration of
CO.
In a closed space, such
as
the engine compartment, the boat,
or underneath a stem swim platfonn. concentrations
will
potentially rise
to
the undiluted level emanating from the
exhaust system due
to
a lack of fresh air
to
dilute
the
exhaust
gas. Therefore, one should never rely on dilution of
the
exhaust
to
provide a margin
of
safety.
Westerbeke
Safe-CO generators achieve
an
approximate 99%
reduction of typical
CO by precise control control of
the
engine's air/fuel ration coupled with after treatment in a
special catalyst.
CO emissions are not the sarne for every
model because each engine
is
different. Also, certain fuel
system components are commonized across several engine
models being adequate for some and extra-adequate for
others, thus producing different
CO levels for different
models.
The fuel system which accomplishes the required precise
air/fuel ratio control
is
comprised of many different
components: purchased sub-assemblies, machined castings,
sensors, electronics and others. Because
of
the
extreme level
of
CO reduction, any variability
in
the
functioning
of
any
these components can and will cause variability
of
the
CO
output.
CO concentration also varies with load. Usually, but not
always, the worst case
CO concentration occurs at maximum
load.
INSPECTION
The catalyst
is
critical
to
optimizing CO levels. Any water
intrusion into the exhaust system will likely quickly
compromise the proper operation
of
the catalyst.
Westerbeke's exhaust system installation instructions dated
on or after February
2004 must be adhered to.
NOTE:
Water intrusion is not a product defect
and
is
not
covered under warranty. neither Westerbekes nonnal
product warranty nor the emissions specific warranty
mandated by various regulating authorities such as
EPA
andCARB.
Maintenance of any components affecting
the
flow
of
air or
the
flow
of
fuel
to
the engine
is
critically important, such
as
fuel filters and air filters (if any).
Inspection of the catalyst at the prescribed intervals
is
critically important. The exhaust elbow
is
removed
by
loosening the metal clamp
to
provide a view of the output
surface
of
the catalyst. Any visual irregularity
of
the normal
flush,
honeycomb appearance
is
most likely a result of water
intrusion. The cause of
the
irregularity must be identified and
addressed.
If
there is irregularity, the catalyst and gasket must
be
replaced. Upon careful reassembly of the catalyst, exhaust
elbow gasket, and exhaust elbow, check for the presence of
CO
while
the
engine
is
running. This must be performed with
a
CO analyzer .
