occurs when an x-ray beam strikes or has passed through any material.
The X-ray producing equipment is installed in a cabinet providing appropriate radiation shielding, the user
should be aware that the useful beam can constitute a distinct hazard if not employed in strict accordance
with instructions contemplated to provide maximum safety for the operator.
Also, the electrical circuits, although enclosed for the protection of the operators, must be considered as a
potential hazard calling for strict observance of safety practices pertaining to operation and maintenance.
Proper electrical grounding must always be used.
Before using the equipment all persons designated or authorised to operate the equipment, or supervise its
operation, must have a full understanding of its nature and become familiar with established safe exposure
factors by a careful study of the National Bureau of Standards Handbook “ X-ray Protection” HB93,
pertaining to X-ray protection.

INTRODUCTION
The SCANMAX 25 is a fluoroscopic X-ray cabinet specifically designed for the detection of explosive
devices, hate mail and other contraband material concealed in incoming mail and packages. Items are
placed in the inspection chamber and simply by pressing a push button switch a high resolution image is
displayed on the video monitor. Image reversal, high penetration and 2 different colour palettes are
available. These and the zoom facility will expedite the recognition of the items in the package.
It is ideally suited for use in government and commercial mailrooms, embassies, prisons and courtrooms. It
can also be used in reception areas for the inspection of briefcases and hand-delivered items not passing
through the central mailroom.
The SCANMAX 25 is completely self contained and can be put into operation immediately and can
examine the contents of a parcel 40 x 50 cm (16” x 20”). A parcel, briefcase or a batch of
envelopes/small packets can be examined in less than 10 seconds.
The SCANMAX is designed to ensure operator protection against radiation hazards through the use of lead
shielding. An interlock system on the door prevents the generation of X-rays when the inspection chamber
door is opened, ensuring maximum protection to personnel. Even so, always be aware that radiation (X-
rays) can constitute a distinct hazard if not employed in strict accordance with the instructions provided in
this manual.
Before operating the SCANMAX 25 all personnel designated to operate the unit, or supervise its operation,
must have a full understanding of the contents of this manual.
UNPACKING INSTRUCTIONS
The installation of the SCANMAX 25 is relatively simple and requires no special tools. It is shipped as a
whole in a sturdy ply wood container mounted on a wooden pallet. The shipping crate is designed to
withstand normal handling during overseas shipments.
Despite these safeguards, damage may occur in transit. Therefore, immediately inspect the exterior of the
container for evidence of damage. In the event damage has occurred, immediately notify the carrier at your
location.
UNPACKING THE SCANMAX 25
To remove the SCANMAX from the shipping crate, perform the following:
1. Undo the binding and open the box with the help of a large screwdriver.
2. Using extreme care, remove the pallet and lift the equipment into place. For this use a lifting trolley
or fork-lift truck. Care must be taken to avoid scratching the unit.
3. Inspect the SCANMAX cabinet for evidence of any physical damage.
WARNING: Physical damage to the SCANMAX cabinet may result in excessive radiation emission
levels. Any damage observed should be thoroughly investigated, prior to operating
the unit and must not be used until authorised.
Fitting of Handles
Handles have been provided for the location of the units at the time of installation, when they require to be
dismounted from their wheeled base or for relocation of the unit.
The handles are universal in that they are designed to fit any of the range of Scanmax units. The outer holes
are for the Scanmax 20 the centre for the Scanmax 25 and the inner holes for the Scanmax 15.
Screws have been provided at the front and rear of the unit to fit the handles.
The only tool required is a screwdriver with a narrow shaft with the head of the screwdriver small enough
to fit through the holes on the handle.
Simply remove the screws from the unit and with the open side of the handle uppermost place the screw in
through the top and through the rear hole. Line up the screw with the unit and tighten.
When the unit is positioned remove the handles and replace the screws into the unit. Do not operate the unit
with the handles fitted. Do not attempt to open the door on the Scanmax 20 with the rear handle fitted.
WARNING
When lifting the unit extreme care must be taken as the units are top heavy.
It is strongly recommended that four people are used to lift the units one at
the end of each handle.
IMPORTANT:
INSTALLATION ADVICE WHEN USING A SUPPORT TROLLEY
TO FIT THE TOP UNIT TO THE BASE THE FOLLOWING PROCEDURE MUST BE USED
1. Ensure that the feet have been removed from the base of the Scanmax before attempting to place
the unit on its trolley.
2. The unit can be placed on the trolley in either direction.
3. Assemble the unit at, or close to, the intended site of operation as the Scanmax 25 is top heavy
when on its base. Care must be taken whilst moving the unit on its base.
4. Fit the feet up through the trolley to secure the unit. This ensures that the feet are available for use
if the unit is to be operated dismounted and also will ensure that unwanted light does not enter the
cabinet through these holes.
PRE INSTALLATION GUIDE
WARNING: To ensure operator safety, radiation emission levels must be checked before putting
the SCANMAX into operation (See page 20)
Prior to first time operation, it is essential for the safety of the operator and for the long life of the
equipment that the following instructions are strictly observed.
Ensure that the system voltage is the same as the mains supply voltage available. If in doubt regarding the
mains voltage at hand, perform a measurement. Units will be set at 230V unless otherwise instructed and
should therefore only be operated from a 230V mains supply. Connecting to a different mains voltage will
result in improper operation or even destruction of the unit.
Ensure that a good mains earth is provided. To minimise shock hazard the SCANMAX must be
connected to an electrical ground or earth. The unit is equipped with a three conductor AC mains lead.
The corresponding socket at the installation must be fitted with a reliable protective earth contact.
SCANNA or the supplier cannot be held responsible for incorrect connection.
Do not operate the equipment in the presence of flammable gases or fumes.
protective devices (fuses etc.).
INSTALLATION GUIDE
1. Take unit out of box (following the instructions in the previous section) and place on a
strong table/base, or the trolley if provided, capable of supporting up to 200 kgs. Take
extreme care when lifting as the unit is very heavy (160 kgs/352 lbs). Use a lifting trolley
or fork lift truck. Ensure that there is unrestricted access to the inspection chamber door.
Ensure that the door is fully closed.
2. Connect monitor to unit by means of the ‘D’ connector and power cables supplied
3. Connect the trackball and place on a suitable surface. (Can be hand held during operation)
4. Plug unit into the mains supply after checking voltage of machine matches local voltage
5. Ensure that the door is fully closed and insert the key into the key switch on the front
control panel and turn it clockwise to switch on the unit. The green SYSTEM READY
light should illuminate to indicate the interlocks have been operated and that the equipment
is ready for use.
6Perform interlock check by doing the following:
Activate the red X-RAY ON button on the front control panel. Observe that all X-ray
lights illuminate and that they remain illuminated. Slowly open the loading door and verify
that the X-RAY ON and warning indicators switch off as soon as the door is opened.
7. Check image quality by placing a sample package into the centre of the inspection cabinet.
8. Using the Trackball check that the left hand switch rotates through the zoom function and
that the right hand switch rotates through the six image formats.
IMPORTANT
Upon installation and after any relocation a critical examination report should be carried by qualified staff
with the appropriate radiation survey equipment using copy of the report found on page 23 for record
purposes.
If all controls function properly and the radiation tests show the equipment to be safe then the SCANMAX
is ready for operation
WARNING
THIS EQUIPMENT PRODUCES IONISING RADIATION WHEN ENERGISED AND SHOULD BE
OPERATED ONLY BY TRAINED PERSONNEL
IMPORTANT SAFETY PRECAUTIONS
The SCANMAX 25 utilises an X-ray generator that is lead shielded against radiation emissions. The
generation of X-rays stops automatically as soon as the door is opened, accidentally or otherwise. This
high level of safety conforms to the strictest protective measures against radiation.
The SCANMAX 25 is inspected, and the results documented, prior to shipment to ensure that radiation
emission levels are well within the legal requirements.
Modification No modification of the SCANMAX, particularly the radiation chamber, should be
attempted without written consent from the manufacturer.
Support If the SCANMAX is moved after initial operation, extreme care should be taken to
ensure proper handling. Use mechanical aids such as forklifts or lifting jacks. Do
not place the unit on an inadequate support or try to lift it unaided. If the unit
is dropped, do not attempt to resume operation before consulting a qualified
service technician. The user must be aware that excessive radiation leakage could
develop due to mishandling.
Relocation A radiation leakage survey, conducted by highly qualified personnel, must be
conducted and documented (see page 23) after any relocation of this equipment or
after any modification to the equipment. This procedure will prevent radiation
health hazards to operating personnel.
Grounding To avoid electrical shock, ensure that the grounding is not defeated.
Wiring All abnormal use or modification of the internal wiring is unacceptable. Scanna
cannot be responsible for any damage or injury caused by such action
Health & Safety UK radiation control regulations require the registration of radiation Sources with
the local Health and Safety Executive. Registration should be made within 30
days of purchase. Contact your local HSE for further information.
