6. FUNCTIONALDESCRIPTION
OF THE XR 24 PRO
When the mains button is pressed
(min. 2 sec.),,
,,
, the display is illuminated. The
heating-up phase for the developing bath and
the fixing bath begins. The time remaining
until the correct temperature is reached is
displayed in the following manner: “WAITING
TIME… MIN” (display flashes). The machine
does not start at this point.
The bath begins to rotate when it is being
heated up. While this process is taking
place, the chemicals are pumped from the
developing tank and the fixing tank (volume of
5 litres for each tank) into the lifting tray (22)
via the circulation pump (14).
When the set temperature is reached, the
display lights up. The “MACHINE EMPTY”
message appears, indicating that the
machine is now ready to be operated.
As soon as the set temperature falls below
more than 0.5°C, the continuous heater and
the circulation pump (14) are switched on
again.
When a film is slid into the machine, the
start flap (2) opens and the “MACHINE
EMPTY” message flashes on the display
At the same time, a signal for lowering the
lifting tray (22) is triggered and the water
valve (15) opens. The drier heating unit (10),
drive motor (12) and circulating pump (14)
(for rotating the developing bath and the
fixing bath) start up.
The time it takes the film to pass through
the machine is controlled by a tachometer
generator (12a). The lifting tank’s rising and
falling movements are controlled by the disc’s
and the light barrier’s (19a) rotational speed.
When the lifting tray (22) is lowered, the film
is carried between the rolls through the
developing bath and the fixer bath, as well as
through the rinsing and drying zones (8)
within the time set for same.
While the film is being developed, water is fed
into the rinsing zone via water inlet (7).
The water is discharged via the outflow pipe.
Water flows through continuously at a rate of
2 l/min., with water pressure of 2 bar.
Should the outflow pipe be blocked, a signal
is sounded via a level sensor (13). The
water valve (15) closes and no more water is
fed into the machine.
When the film has been slid into the
machine, the start flap (2) closes. As soon as
the message “MACHINE LOADED” flashing
on the display goes out, another film can be
introduced, or up to 6 intra-oral films, can be
introduced together.
If no other film is slid into the machine when a
particular film has passed through it (this is
signalled by a sound) the lifting tray (22)
moves upwards (to stand-by position),
indicating that the machine is now empty.
The drive motor (12), water valve (15) and
drier heater (10) are switched off. When the
machine is in stand-by position, the
developer’s and fixer’s roller packets are
completely immersed in the chemicals. This
prevents deposits from forming on the rollers.

MOUNTING AND ASSEMBLY
7. SETTING UP
7.1 Area inwhich machine
is to be set up
• The XR 24 PRO developing machine should
only be set up in a dry, well-aired room.
• In winter, the room temperature should not
fall below +10°C; in summer it should not
rise above +28°C.
Danger. The appliance should not
be directly exposed to the sun’s
rays. There is a danger that the
chemicals may overheat or that the
films might be pre-exposed.
• The room in which the machine is being set
up must contain a R3/4” bibcock (27) with a
ventilation pipe, an outflow pipe (28) with a
ventilated plastic trap, and an earthed plug
(26). Ideally, a washbasin should also be
situated close to the machine.
The operating staff must have easy
access to the bibcock (27) and the
earthed plug (26)..
• We recommend that the XR 24 PRO be set
up in a darkroom. If the machine is notnot
notnot
not set
up in a darkroom, a daylight attachment
(24) (DL24 or DL26) must be fixed to it.
• The following should be taken into
consideration if the machine is being used
with a daylight attachmentwith a daylight attachment
with a daylight attachmentwith a daylight attachment
with a daylight attachment:
Danger. Films should never be
stored in the vicinity of an X-ray
room
Danger. When films are stored in
the daylight attachment’s film
storage part (25), there is a danger
that pre-exposure can occur due to
stray radiation in the appliance.
If necessary, a partition with a lead screen
may be inserted.

7.2 How to set up machine
• Set the machine up on a horizontal, stable,
even board at working height.
• When the tubes are being passed under,
the board must have an opening measuring
ca. 7 x 10 m
• Ensure that additional space is available so
that servicing work can be carried out and
so that the machine is adequately
ventilated:
There must be at least 10 cm of free
space behind the machine and ca. 50 cm
free space left and right.
At the front there must be enough space in
case a daylight attachment (24) has to be
fixed to the machine. If necessary, detach
the installation feet at the front and screw
them on to the back.
7.3 Setting up the machine
• Undo the plastic bands attached to the
cardboard packaging.
• Take out all small parts.
• Grip the sides of the machine and place it
in suitable position.
• Set it up close to a mains water supply, an
outflow pipe and an earthed pipe (max.
distance 1.5 m)
• Set up the appliance so that it has a slight
tilt, ca. 0.3 ° to the fixer bath (fig. 8).
Adjust the feet of the appliance (29) using
the spanner provided (30) as required.

8. INSTALLATION
8.1 Mains water supply
• Check whether or not pure water is flowing
out of the bibcock (27). When the machine
is being installed initially, rinse the
pipelines thoroughly!
• Because the water quality can vary greatly
from region to region, a fine-mesh filter (32)
must be inserted between the bibcock (27)
and the water pipe (34).
The fine-mesh filter (32) protects the
flow-through limiter in the appliance’s
water valve from impurities
• Close the bibcock (27).
• Connect the 90º bow to the bibcock (27).
Attach the fine-mesh filter (32) (arrow in flow
direction) and double nipple (31) to the
bibcock
Check whether the strainer (34a) and
both seals (34b) are present in the
water pipe’s (34) threaded joints.
• Connect the water pipe to machine’s water
intake point (35) (threaded joint with
strainer) and to the double nipple (31).
8.2 Wastewater connection
• The wastewater connection may only be
connected via a ventilated siphon.
• Move the outflow pipe (36) to the siphon at
a continuous slant. Shorten the pipe to the
correct length.

When moving the outflow pipe,
avoid sagging, constrictions and
reductions.
• Cover exterior of end of pipe with UHU
plaster
• Screw screwed fitting (37) to pipe and
attach to siphon’s (25) muff using pipe clip
(38).
• Secure outflow pipe using pipe clips,
screws and pins.
• The washing basin’s outflow point must be
open!
8.3 Connection for developer and
Fixer outflow pipe
• Set up the collecting tray (39) for the
developer (black level marking) and the
fixer (red level marking) beneath the
appliance so that it is clearly visible and
stable
•Move the pipes (40) at a continuous slant
• Shorten the pipes to the correct length.
• Feed the pipe for the developer (black
marking) into the black lid (41).
• Screw the lid (41) to the collecting tray (39)
for the developer
• Secure the pipe for the fixer (red marking)
to the collecting tray for the fixer in the
same way
When the full level marking has
been reached, empty the collecting
tray (danger of overflow). When
disposing of the developer and the
fixer, regional regulations must be
complied with. In Germany and in
several other countries X-ray
chemicals are classified as special
waste, and are disposed of
accordingly.

The operating instructions on the
display for the user are contained in
the chapter on USAGE, point 14
Detailed instructions on how to
service the machine are listed under
maintenance, point 18.6.
• The developing machine must
never be used without roller
packets!
If no roller packets are used, the
developing and fixing fluids can
spurt up and out of the developing
unit when placed under pressure.
Chemicals irritate the eyes and
skin. Serious injuries can be
incurred.
•If no developing and fixing roller
packets are used, the chemicals
cannot be directed into the tanks
There is a danger of the chemicals
being mixed together.
• The developing machine should
never be operated without fluids
(chemicals, water). This can lead
to malfunctioning of the heating
control system.
12. FIRST TIME OPERATION
The XR 24 PRO developing machine has
three settings which determine the amount of
time it takes a film to pass through the
machine. The following values are set for the
machine “ex works”:
Intra-oral films 6 min. (INTRA program)
Extra-oral films 4 min. (EXTRA program)
Endodontal films 2.45 min. (ENDO prog.)
Note: It is not possible to archive X-ray films
which pass through the machine during this
short period of time).
- Developing bath and fixing bath
temperature: 28 ºC
- Drier capacity: 30%
When films with different drier capacities,
