2011 Four Winns V335 Boat Owners Manual

W.  Maintenance - Ventilation Systems
3.   Check that water traps and condensate drains
are present.  These may be in the form of a double
loop in the drain line or prefabricated p-traps. Any
drain that discharges below the waterline when the
boat is underway is sealed,  by virtue of its design,
against CO intrusion.
Boats are equipped with ventilation systems to
eliminate gasoline vapors. Blowers and fans may also
be provided for ventilation and to mitigate the migra-
tion of CO into occupied compartments. Attention
should be paid to the following:
Z.   Maintenance - Liquid Drains
Keeping ventilation intakes clear of debris
Sink, shower and condensate drains can be a source
of CO ingress. Ensure that water traps are present
and contain fluid. These traps may be in the form of
a double loop in the drain line or prefabricated p-traps.
Any drain that terminates below the waterline is, by
virtue of its design, sealed against CO intrusion.
Some drains that are below the waterline when boat
is underway will be above the waterline when the
boat is at rest. The location of drains, relative to the
waterline, can be affected by the dynamics of boat
motion (i.e., underway or at rest).
.   Replacing damaged hardware
3.   Maintaining the integrity of the ducting material
and its connections
.   Ensuring that position of ducting intake is not
obstructed or restricted, collapsed, kinked,
or crushed.
5.   Eliminating sags in ducting that can form
a water trap
AA.Carbon Monoxide Detection Systems
Checking hangers and other supports
Four Winns has included two CO detectors as a
standard feature. One of the CO detectors is located
in the forward V-berth and the other is located in
the aft/mid cabin. Check systems and maintain in
accordance with the manufacturer’s instructions.
.   Ensuring blower/fan is operational
8.   Ensuring that airflow is present at discharge
Inspecting wiring to equipment
X.   Maintenance  - Bulkhead and Deck Integrity
Never disarm a CO detector. If a CO detector
alarms, immediately ventilate the area and
check passengers for symptoms of CO
intoxication. See your Four Winns dealer for
assistance in diagnosing the cause for the
Seal all visible openings (e.g., cracks, crevices,
holes, including openings around wiring and
piping runs) in bulkheads and decks that separate
machinery compartments from occupied compart-
ments. These openings can permit migration of
CO vapors.
Check gaskets and sealing surfaces on hatches,
doors, and access panels.
For information on CO Detection Systems,
see American Boat and Yacht Council (ABYC
Manual) Section A-24, “Carbon Monoxide
Y.   Maintenance - Air Conditioning Systems
These systems can be a source of CO ingress
and migration of CO vapors.
Even with the best of boat design and construction
along with the utmost care in inspection, operation,
and maintenance of boat systems, hazardous levels
of CO may still be present in accommodation spaces
and exterior areas under certain conditions. Vigilant
observation of passengers for CO sickness symptoms
should be supplemented by a marine CO detection
device in the accommodation space.
1.   Keep grilles and filters clean.
.   Seal bulkhead voids and openings at wiring and
piping runs in return air ducting, plenums, and air
handling equipment enclosures, especially those
adjacent to machinery compartment bulkheads.
