Welcome to the world of SUEX
SUEX S.r.l. congratulates and thanks you for your trust in purchasing our Diver Propulsion Vehicle, hereafter called
" DPV". Every DPV is the result of extensive experience and prolonged prototype testing. A capable and creative
staff, assisted by highly courageous diving experts with proven professional and recreational abilities, have created
this and other DPV to assist and extend your underwater dives.
However, never overestimate your abilities and always undertake specific underwater diving courses to be able to
use your DPV in total safety.
Always remember that fun should NEVER put your life at risk.
The SUEX staff

WARNING!
THIS MANUAL CONTAINS IMPORTANT INFORMATION AND WARNINGS FOR SAFE OPERATION OF THE
DPV.
READ BEFORE USING THE DIVER PROPULSION VEHICLE!
The Diver Propulsion Vehicle (hereafter called “DPV”) is delivered in perfect working condition, complete with
the user’s manual;
Any person attempting to use the DPV shall be deemed to have undergone to specific training and be certified
for DPV diving by qualified training agency.
Follow the instructions for safe DPV operation.
The incorrect use of the DPV or the lack of maintenance or regular service can lead to unsafe operation and
ultimately can cause injury/death or loss.
SUEX S.r.l. is not liable for injuries/death and/or losses consequent to the improper use of the DPV or lack of
maintenance.
The DPV is not a toy nor a suitable rescue means.
The DPV and all its components, i.e. the battery and battery charger, are intended for adult and expert use.
Read the manual for battery charge and use.
The DPV is equipped with an internal “cut-off” device that is triggered when the battery voltage drops below a
certain voltage.
When this cut-off device is triggered the DPV stops.
The diver must always be able to safely accomplish the dive even with a disabled DPV.
Due to constant technological developments, the SUEX DPVs may be modified at any time without prior notice.
Contractual terms may apply for version control.
This manual does not substitute an adequate DPV diving course.
Use of the DPV under the influence of alcohol and drugs and in any situation in which psycho-physical
conditions are not suited for diving is prohibited.
ADDITIONAL NOTE!
About the following parts, carefully follow the safety rules:
Prop Lock propeller
In addition to normal DPV use, these accessories make it extremely important that you are
fully aware of their use and operation and the potential hazards that may be associated with
their use. (See specific paragraphs).

1. GENERAL SAFETY AND ACCIDENT PREVENTION REGULATIONS
Pay special attention to the hazard signs in this manual. There are 3 levels of hazard signs:
This sign is a warning that failure of the user to adhere to the described operations will
expose him to health hazards that may lead to serious or permanent harm.
This sign is a warning that failure of the user to adhere to the described operations
may lead to damage of the vehicle.
Copyrights for this manual belong exclusively to SUEX s.r.l. Reproduction of this document, in part or in whole, is
forbidden without SUEX SRL written authorization.
IMPORTANT NOTE!
THE DPV
CAN BREAK
IS NOT A LIFE-SAVING DEVICE!
This sign is a warning that failure of the user to adhere to the described operations
will expose him to possible health hazards that shall not, however, lead to serious or
permanent harm.

Pag. 7/41
2. DESCRIPTION AND OPERATING PRINCIPLE
The DPV consists of a watertight, streamlined, hollow body, see figure1, inside which the electric motor, electronic
boards, rechargeable batteries and are contained. On the outside, one control handle (1) is found at the rear which
has an integrated trigger (2) to activate the propeller rotation by the means of a switch (3). The front handle (4) is
used for gripping and carrying the vehicle. The propeller (10) is located at the rear end and is protected by a shroud
which constitutes the flow conveyor –nozzle - (5). The main switch (6) for turning the power on and off and the
speed regulator knob (7) are also found at the rear.
The nosecone is in front (8). The fastening knob (9) is inserted in the nosecone. In order to access the battery
compartment remove the nosecone.

3. USING THE DPV
The DPV manufactured by SUEX s.r.l. has been designed and built for towing a diver underwater. Any alterations
that may substantially modify its intended purpose are forbidden.
Custom Suex engineering exclusions apply.
The DPV has been designed, sized and built for the sole purpose described above. Any other
use or operation that does not comply with the instructions contained in this manual, may
damage the DPV. This would prevent the conditions for which it has been designed and built
from being achieved, and may compromise its technical and safety characteristics. The
manufacturer shall not be liable for damage to persons and/or objects deriving from
inappropriate use of the vehicle.
4. PACKAGE CONTENT

A DPV
A battery
A battery charger
An accessories kit
5. PRELIMINARY OPERATIONS
The following operations can be carried out after a complete and careful reading of this instruction manual
by trained personnel:
Verify the DPV is not damaged and fully operational
Verify that the DPV is hermetically closed
Verify that the battery is fully charged and connected to the motor
Verify that the towing system is fully operational
5.1. DPV START
Once the preliminary operations are carried out
Submerge the DPV
Verify that the propeller is free of any obstruction, debris
Turn the main switch in ON position (6) (see fig.2).
Hold the DPV’s handles (1) (see fig.1).
Pull the trigger(2), The DPV starts to run
Pull off the trigger and the DPV stops
Start the dive

Pag. 9/41
5.2. OPENING THE BATTERY COMPARTMENT
Put the DPV in vertical position on the shroud (5) on a flat surface.
Turn the front fastening knob (9) counter-clockwise. When rotating the knob the nosecone (8) (see fig. 1) starts to
lift. Continue rotating the knob until the nosecone detaches from the body. Remove the nosecone.
5.3. EXTRACTING THE BATTERY
After removing the nose, disconnect the red connector (15) (do not pull the cables), unscrew the ring nut (11) and
loosen the eccentric terminal. Remove the battery (14). (fig.2).
Fig.2

Pag. 10/41
5.4. RECHARGING THE BATTERY
In order to recharge the battery (14), extract the battery out of the DPV (see fig. 2), put it in a safe place away from
people and flammable objects. Connect the battery charger power cord to the mains. Next plug the charger
connector into the battery’s charge socket (15) (see battery charger instructions). When the battery is fully charged,
disconnect the charger and put the battery back into the DPV.
THE BATTERY SHOULD BE CHARGED USING THE CONNECTOR ONTOP OF THE
BATTERY LID (26) ONLY!
ATTEMPTING TO CHARGE THE BATTERY THROUGH THE BATTERY - MOTOR
CONNECTOR CAN LEAD TO FIRE, EXPLOSION, PERSONAL INJURIES AND DEATH.
5.5. INSERTING THE BATTERY
With the DPV in vertical position, repeat the battery extraction procedure in the reverse order.
BE CAREFULLY TO CORRECTLY POSITION THE BATTERY.
5.6. CLOSING THE BATTERY COMPARTMENT
Put the DPV in a vertical position on the shroud. Check carefully that the nosecone O-ring (19), (see fig. 2) is
properly seated, clean and properly greased with vaseline grease.
Check that the seat of the body (20), is clean. If necessary properly clean it with a suitable cloth to remove any dust
or sand. Insert the nosecone(8) matching the screw (18) up with the hole (17). Finger-fasten the knob (9) clockwise
until it closes completely.
