This processor is fitted with indicator lights illuminated RED. When lit, these indicate that
the processor is switched ON and operating correctly.
In darkroom conditions, red illumination is used to prevent film fogging and, on this
processor, it is NOT indicating a dangerous condition.
DISCONNECT MACHINE FROM THE MAINS ELECTRICAL SUPPLY WHEN IT IS
NOT IN USE, OVERNIGHT AND WEEKENDS.
POSITION THE MACHINE TO ALLOW EASY DISCONNECTION FROM
ELECTRICAL SUPPLY.

TECHNICAL DESCRIPTION
---------------------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------
The Velopex "Sprint" X-Ray Processor is a machine for developing and fixing dental
x-ray films without user contact between insertion of the exposed film and receipt
of the developed film into the wash-tank for collection at the end of the process.
The machine receives undeveloped film in a light-tight enclosed area, visible
through its protective red perspex flap, where a motor-driven “module" carries it
between two continuous belts through a tank containing Developer. The film is
passed out into an identical "module" working in a second tank, containing Fixer.
Chemical temperature is maintained at 27°C, (81°F), by two rod heaters protruding
from the rear wall of the machine, heating each chemical tank through a metal
sleeve.
The film finally passes into a water Wash Tank after processing. It is retrieved by
removing the film from the collector tank.
The overall dimensions of the processor are:- width 380mm (15 inches), with
water tank fitted; height 450mm (17¾ inches); depth 230mm (9 inches).
The weight of the processor is: empty, 6.85 kg (15 Ib); full, 10.25 kg (22½ Ib).
This machine is a CLASS I device.
ENVIRONMENTAL CONDITIONS FOR TRANSPORT AND STORAGE
This machine should be kept within the temperature range -10°C and +40°C,
(14°F and 104°F) and below 80% humidity.
INTERFERENCE BETWEEN EQUIPMENT
This X-Ray processor complies with the following E.M.C. Standards
E.E.C- EN6060I-1-2
U.L- FCCPart 15 Class A
In the event that electromagnetic or other interference is suspected between this
processor and other equipment close to it, move the two units further apart until
the problem is eliminated.

SITING THE SPRINT
---------------------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------
PRE-INSTALLATION INSTRUCTIONS
Although the Velopex Sprint is designed for use in daylight, care should be taken
to avoid sources of intense light. For example do not site directly under a window,
fluorescent tube or floodlight.
A well ventilated position is mandatory.
The SPRINT has been designed for use on a normal counter-top or for
wall-mounting. It is important that when the machine is filled with solution the
stand does not rock or shake, as this could cause spillage. Never move the
machine with chemicals in the tanks.
Avoid siting the machine above or near other electrical, mechanical or sensitive
apparatus - e.g. autoclave, compressor, evacuation equipment.
Place the machine against a wall to prevent it from being accidentally knocked
over.
The machine should not be placed in areas exposed to flammable gases.
When the machine is to be sited in a darkroom, it is essential to ensure that the
room is well ventilated and light-tight. There should be sufficient space for easy
chemical changes and for the machine to be serviced safely.
When choosing a site for your Velopex it may be convenient to site the machine
near a sink for ease of chemical changing.
When choosing the site, it is important to allow for the presence of liquids.
Surfaces susceptible to water (or chemical) damage should therefore be avoided.
Avoid carpeted areas.
The ambient temperature must be maintained below 27°C (81°F).
WARNING: X-ray radiation can be harmful to patient, technician and
dentist. Inadequate lead shielding of the darkroom or film storage area
will also cause fogging of films from exposure to stray x-ray radiation.
Consult your Radiation Protection Adviser, your local bye-laws, your
Department of Health and Safety or Dental Equipment Dealer for proper
construction of darkroom or placement of film processing equipment in
the vicinity of x-ray radiation sources.
CLEANING THE PROCESSOR CASING
Keep the outside of the machine clean with a mild solution of household
detergent and warm water (not boiling).
Use a damp cloth only (wring all excess water out of the cloth) and wipe the
external surfaces, exercising extreme care around the electrical components.
WARNING: Ensure that the machine is disconnected from the mains
power supply during cleaning and never allow water to seep into the
casing.
