INTRODUCTION
DUFOUR YACHTS is delighted to present you with this manual that will enable you to
get to know your boat better.
This manual has been produced to help you enjoy the use of your boat in complete safety.
Read it carefully, in particular to avoid fire and flooding risks, and familiarize yourself with
your boat before using it.
If this is your first boat, or if you are changing to a type of boat you are unfamiliar with, for
your convenience and safety, make sure you gain experience in handling and use before
taking command of your boat. Your agent, your national yachting federation or your yacht
club will be more than happy to recommend local sailing schools or qualified instructors.
KEEP THIS MANUAL IN A SAFE PLACE AND PASS IT ON TO THE NEW
OWNER IF YOU SELL YOUR BOAT.
NOTICE: Our boats are regularly improved in the light of our customers' experiences and
research by the shipyard, and so the specifications given in this Owner's Manual are not
contractually binding and may be changed without notice and without any obligation to
update.
This manual is intended to cover as much information as possible, so certain equipment or
paragraphs might not apply to your boat. In case of doubt, please refer to the inventory
which should have been given to you by your agent when you placed your order.

1. DESIGN CATEGORY OF YACHT
Your DUFOUR 34 comes under the OCEAN-GOING design category (category A).
In normal conditions of use, your boat is designed for sailing with effective wave heights up
to 7 m and winds of Beaufort Force 10 or less, and to withstand the severest conditions.
This sailing capability is equally dependent on the skills of the crew, their physical capacities,
the maintenance of the boat and its equipment.
So always take care before putting to sea.
DUFOUR YACHTS is not able to guarantee perfect functioning of the boat in exceptional sea
conditions (violent storms, hurricanes, cyclones, waterspouts,...)

3. ELECTRICAL SYSTEMS
3.1. Safety and operating instructions for the electrical system
WARNING
Always:
−Check the condition of the batteries (charge and electrolyte level) and the charging
−system before putting to sea.
−Disconnect and remove batteries for wintering.
−Do not let battery voltage drop below 10·5 V during wintering.
−Carry spare lamps for all navigation lights and interior lighting.
−Respect power ratings, particularly for navigation lights.
−Check operation of the navigational instruments.
−Check operation of navigation lights before night sailings
Never:
−Work on an electrical installation that is live.
−Make any modification to an installation and the relevant diagrams, unless it is
carried out by an electrician qualified in marine electrics.
−Change or modify the breaking capacity of overload protection devices.
−Replace electrical apparatus or equipment with units exceeding the rated capacity
without uprating wiring and protection.
−Leave the boat unattended when the electrical installation is powered, with the
exception when applicable of the automatic bilge pump and the fire or theft
protection circuits.
If a fuse or circuit-breaker blows continually, a specialist must be consulted to
determine the origin of the short-circuit.
3.2. Installing new equipment
Since the 1st January 1996, electrical equipment is subject to the European
"electromagnetic compatibility" directive (Ref 89/336/CEE). Hence it is necessary to
install new equipment meeting this standard and bearing the CE mark. Equipment must
also be supplied with a compliance certificate and instructions for use.
In the case of 220 or 110 V installations, use only double-insulated or earthed
equipment. When such equipment is being installed, respect the fitting instructions
(conductor size, protection).
To avoid maintenance problems, be sure to mark in the manual and modifications that
may be made to the electrical diagram.

3.3 Batteries
The battery capacity has been designed to meet the power requirements of the on-board
accessories. To avoid any problems, it is necessary to keep a close eye on the
maintenance and correct charging of the batteries.
NOTE
- When installing new electrical appliances, take care that the overall consumption of
these appliances remains within the capacity of your batteries.
-Always disconnect the -ve battery terminal before the +ve terminal
-Never allow a conductive object (tools, etc…) to bridge the two battery terminals
-When handling batteries, keep them horizontal to avoid spillage of electrolyte. Wear
gloves and protective clothing that will prevent any risk of contact with electrolyte
in the event of a leak.
-In the event of electrolyte splashes, rinse the affected part of the body copiously and
consult a doctor.
3.4 Electric winch
NOTE
It is essential to run the engine with the throttle slightly open when using the electric
winch.

3.5 220/110 Volt installation
DANGER
The on-board 220 or 110 V installation is protected by a circuit breaker and fitted with a
residual current device. The wiring of additional 220 or 110 V on-board accessories
must be carried out by professionals, with uprating of the master circuit-breaker if
necessary.
DANGER
Your boat is not supplied with a shore/boat supply cable or a male plug for the shore
outlet. The cable must be suitable for outdoor use. Its cross-sectional area must be
adjusted according to its length and the rating of the main circuit-breaker (see
electrical diagram). The plug must be suitable for the female socket on the shore (if
necessary, seek the advice of a professional)It should be as near as possible to the IP
67 / IEC529 type
-Switch off the shore supply at the on-board isolator before connecting or
disconnecting the shore/boat supply cable.
-Connect the shore/boat supply cable at the boat end before connecting it to
the shore outlet
-Disconnect the shore/boat supply cable at the shore outlet before
disconnecting it at the boat end
-Close the shore outlet cover properly

4. GAS INSTALLATION
4.1 Operating advice
−Read the instructions for the cooker and regulator carefully.
−Ensure that the gas cylinder and regulator are in accordance with the requirements of
the cooker (flow rate, pressure, type of gas).
−Ensure that the gas cylinder complies with the regulations in force in the country
where it is being used.
−Appliances burning fuel use up the oxygen in the cabin and release combustion
products into the boat. Ventilation is required when appliances are alight. Open the
coachroof ports while you are cooking.
−Do not use the oven as a heater.
−Do not obstruct quick access to the elements of the gas installation (cylinder locker,
shut-off valve).
−The gas cylinder must always be stowed in the space provided
−Never leave the boat unattended when gas appliances are alight.
−Close all valves in the circuit when the boat is left empty (shut-off valve, regulator
valve), even if the cylinder is considered to be empty.
−After the boat has been shut up, never smoke when going below, and ensure that
there is no smell of gas.
−If you smell gas, close the circuit valves and the cooker taps, ventilate the boat, and
find the leak before using the installation again.
WARNING
In the event of an emergency, the circuit valves must be closed immediately.
