3.3 IDENTIFICATION DATA

15 of 36
MAINTENANCE AND USE MANUAL
DUNE
The DUNE has been designed to sandblast items used in the odontotechnics field. The DUNE
unit is available as the DUNE Mod.2 (two nozzles) and the DUNE Mod.3 (three nozzles). The
constant-pressure tungsten carbide nozzles are available in various sizes so that the
technician/operator can set up a sandblaster that meets his requirements perfectly.
The following items are supplied as standard:
• n.2 nozzles ø 0.8 mm fitted on handpieces for DUNE Mod. 2
• n.3 nozzles ø 0.8 mm fitted on handpieces for DUNE Mod. 3.
The tank cylinders feature an efficient constant vibration system, specially designed to keep the
sand on the move at all times; this prevents the formation of lumps which might obstruct the
nozzles. Furthermore, a new air pumping system inside the cylinders themselves ensures that
all the sand exits the cylinders, thus eliminating the problem of continuous top-ups and breaking
up any lumps of sand that have been caused by damp.
Because there is a not just one cylinder but a set of them the equipment features a switch for
fast sandblasting change-overs: This makes work easier when different types of sand need to
be used.
DUNE Mod. 2 is built so that an optional third cylinder unit with pressure reducer, gauge and
handpiece body can be added if desired.

MAINTENANCE AND USE MANUAL
DUNE
It is recommended that you keep the original packaging so that, if necessa-
ry, it can be re-utilised; doing so ensures that you do not use unsuitable
packaging materials during transport and mounting which might lead to
accidental damage (see section 5.3).
5.1 WARNINGS
5.2 PACKING AND UNPACKING
All the material is thoroughly checked by the Manufacturer prior to shipment. When you
receive the goods make sure they have not been damaged during transit and that no-one has
tampered with the packaging and removed any of the parts contained therein.
Should there be any damage or missing parts you must inform the Zhermack S.p.A. Equipment
Assistance Service or the Dealer where the equipment was purchased immediately. The Carrier
must also be informed. Photographic evidence of such damage/missing parts must be provided.
The packaging, consisting of a cardboard box with internal expanded plastic padding, contains:
• the sandblasting equipment;
• the accessories (see section 4.2.1);
• this Use and Maintenance Manual.
CHAPTER 5: TRANSPORT AND MOUNTING
To prevent any injury to persons or damage to things always proceed with the
utmost care and attention when mounting the equipment. Observe all the
precautions and instructions contained in the following paragraphs.

17 of 36
MAINTENANCE AND USE MANUAL
DUNE
Should it be necessary to move the sandblasting equipment proceed as follows:
1. Disconnect the equipment from the electrical power supply.
2. After cleaning the sandblaster thoroughly (see Chap. 8), disconnect the compressed air
tube; then disconnect the aspirator coupling.
3. Gather all its accessories together.
4. Hold the bottom of the equipment, making sure that it is always kept vertical.
Proceed cautiously, bearing in mind the size and weight of the unit (see section 4.2), so as to
prevent any accidents that might be caused by failure to evaluate such factors.
5. Pack the equipment in its original box or, if this is not possible, take all the necessary
precautions to protect the equipment against knocks or drops, in that the goods are transported
at the owner's risk.
5.3
TRANSPORT AND MOUNTING
Failure to observe the above exonerates the Manufacturer from any liability
concerning equipment malfunction and consequently renders the Warranty
null and void.
When shipping/delivering the equipment to your Authorised Servicing
Centre always enclose a copy of the purchase document and a copy of the
properly compiled ID form.
If the unit is to be transported by courier, the postal service or rail it is
recommended such shipments be insured.
5.4
ELIMINATION / DISMANTLING
When disposing of the packaging materials the user must comply with the standards in force
in his/her country regarding the following materials:
• Wood/paper: non-polluting materials, but must be recycled properly.
• Polystyrene/plastic: pollutants which must not be burnt (toxic fumes) nor dispersed into the
environment, but disposed of in compliance with the standards in force in the country of use.
If the equipment is to be dismantled the user must, in compliance with EC directives and the
laws in force in the country of use, effect elimination and recycling of the following materials:
• Plastic and glass parts, insulated electrical wiring, rubber parts.
• There are no toxic or corrosive parts.
This product must not be disposed of as household waste but rather, when
no longer used, must be collected separately according to EC Directive
2002/96.

6.1 WARNINGS AND PRECAUTIONS
CHAPTER 6: INSTALLATION AND FIRST-TIME USE
So as to provide greater clarity the numbers given in the diagrams in this
chapter correspond exactly to the numbering in the Components Table
(Ch. 3).
Work area lighting is an important factor in both personnel safety and the
ultimate quality of the work being done. In Italy lighting must comply with a
Ministerial Decree Law that clearly defines minimum lighting requirements.
In other countries lighting requirements form part of the accident prevention
and workplace hygiene standards.
Before proceeding with installation make sure that all relevant safety conditions prevail and
follow the instructions below carefully.
6.3 REQUIRED WORK SPACE
Choosing a good workplace with an appropriate amount of space available for equipment
installation is an essential factor in personnel safety, the quality of the work and proper
maintenance. This zone must not only be spacious enough to allow for optimum equipment
operation but must also be well illuminated, aired, not dusty and not exposed to direct sun-
light.
6.2 PERMITTED AMBIENT CONDITIONS
Unless stated otherwise at the time of order the equipment will be configured to operate properly
under the following ambient conditions:
Ambient conditions other than those listed above may cause malfunctions or sudden
breakdowns. Lighting in the installation area must be sufficient to provide good visibility at every
single point on the equipment.
More specifically, luminosity must not be less than 200 lux, lighting must be as uniform as
possible and there must be no reflected light as this could dazzle the operator.
Min ambient temperature 0°C
Max ambient temperature 40°C
Max humidity 90%
The equipment must not be used in workplaces having an atmosphere which is
explosive and/or at risk of fire as it has not been designed for use in such areas.
Nevertheless, should a fire accidentally break out follow the procedure described
in paragraph 2.4.

19 of 36
MAINTENANCE AND USE MANUAL
DUNE
6.3.1
Worktops
The sandblasting DUNE equipment
has been designed for use on a rigid worktop
parallel to the floor.
Suitable worktops include service furniture
(where the operator is standing) or modelling
tables (where work is done sitting down).
All worktops must be checked for stability.
6.4
CONNECTING UP TO THE POWER SUPPLY
The user must provide a power connection with relative socket near the equipment installation
point. The user must also install an adequate electrical circuit breaker upstream from the socket
as well as efficacious overload/indirect contact safety devices.
Connection is effected via the safety plug (16A, in compliance with European standards) at the
end of the power lead: this must be inserted in the mains socket.
When connecting check:
• that mains voltage and frequency are as indicated on the identification plate (incorrect power
supply voltage may damage the equipment).
• that the mains supply has a proper, efficient earth connection.
It is forbidden to tamper with the power lead and its plug. When replacing them
owing to damage and/or wear please contact an Authorised Service Centre.
A proper earth connection is compulsory. Should it temporarily be
necessary to use an extension lead the latter must comply with the
standards in force in the country of use.

Failure to observe any of the above equipment installation instructions may lead
to malfunctions and render the warranty null and void.
6.6 PURPOSE OF THE EQUIPMENT / IMPROPER USE AND FORBIDDEN USE
The DUNE units have been designed and built for the sandblasting of odontotechny pro-
ducts.
The main reasons for which the Warranty may be rendered null and void are given in section
2.2 and in the "Warranty Certificate" enclosed with this Manual.
Using the equipment for any purpose other than that described in this Manual
shall be considered improper and thus forbidden.
Improper use renders the Warranty null and void and the Zhermack S.p.A. shall
not be liable for any damages to objects, workers or third parties.
Connect the lead (11) to the mains
power socket: follow the instructions in
section 6.4 carefully.
