7. Functional description
7.1 Brief details
The X-ray film developer XR24Easy is fitted
with a Start-Stop-Automatic�
The appliance on stand-by mode will start auto-
matically on the insertion of a film�
The film will be transported through both the de-
veloper and fixer baths, and then be carried
through the water bath to the drying zone�
Approximately 1 minute after the film run
through process has ended, the machine auto-
matically switches into stand-by mode�
7.2 Warm-up stage
After switching on the main power supply (A) the
yellow LED (B) lights up� As long as the yellow
LED is displayed, the temperature in the develo-
per bath and the fixer bath is being raised�
Heating is effected by a heat cartridge in the
process heater (19)� The temperature, factory-
set, is regulated by a capillary tube controller
(18)�
During the warm-up stage, no film can be pulled
in and developed�
The bath circulation processes (KE) and (KF) of
the developer bath and fixer bath start after a
delay of ca� 60 seconds after the XR24Easy
has been switched on�
The rotary pump (16) feeds developer and fixer
from 5 litre tanks via the process heater (19) into
the bath (23) through two separated hose
systems�
7.3 Operating phase
The XR24Easy is on stand-by mode when the
yellow and green LEDs both light�
When a film is placed in the film insertion slot (1)
it triggers the film feed flap (2) and the orange
LED (D) lights�
The following activities are initiated:
Solenoid valve, motor, heating and rotary
pump
• The solenoid valve (17) serves to open the
water inflow (WZ)� The connection pressure
causes the water to flow to the water bath (W)
and from there to the waste water drainage
(WA)� If the waste water drainage is blocked,
the level will rise in the water bath (W) until the
level sensor (7) closes the solenoid valve (17)
and prevents further water inflow�
• The motor (15) operates the drive shaft (10)
via the roller belt (14)� The toothed cogs on
the roller sets are directly connected to the
worm screw cogs of the drive shaft� This con-
nection serves to rotate the rollers of the roller
sets in order to transport the film through the
various process steps�
The various film processing steps are:
1� Film insertion slot, 2� Developer bath and
Fixer bath, 3� Water bath, 4�Dryer�
• The ventilation fan (13) serves to extract air�
On its way to the drying zone the air is war-
med by the heating system�
The heating temperature is set to a stationary
value�
• The rotary pump (16) activates the circulation
of the developer and fixer baths� During the
operational cycle the capillary tube controller
(18) regulates the temperature of the bath(s)�
After insertion of the film the film feed flap (2)
closes� A further film can be inserted as soon as
the orange LED (D) switches off�
The film travels through the developer bath (E),
then through the fixer bath (F) and finally through
the water rinse bath (W) and always at a con-
stant steady speed� Afterwards the film is dried
by passing through warm air and arrives at the
film outlet slot (8) and leaves the developer�
Approximately 1 minute after the film processing
cycle has ended, the machine is automatically
returned to stand-by mode�
7.3.1 Temperature control
The temperature of the bath(s) is regulated by
the capillary tube controller in the process
heater�
7.3.2 Sealing profile of roller sets
The roller sets developer/fixer (4) and the roller
set water (6) are fitted with extra sealing profiles
(24)� These sealing lips prevent fluids from es-
caping� The level of fluids in the roller sets devel-
oper/fixer are kept to a set level�

8. Set-up
8.1 Room for set-up
• The XR24Easy developer may only be ope-
rated in a clean, dry and well-ventilated room�
• Room temperature must not fall below +10°C
in winter and must not exceed +28°C in
summer�
Never expose the machine to direct
sunlight! Danger of the chemicals over-
heating or pre-exposure of film
materials�
• The room chosen for set-up must have ac-
cess to a water connection (water tap) (28)
R3/4" with pipe anti-vacuum device, waste
water drainage (29) with aeration (anti-odour)
via plastic siphon and an electrical safety so-
cket (27)� Having a sink for washing next to
the developer is also recommended�
The water tap (28) and electrical safety so-
cket (27) must be easily accessible to the
operating personnel.
• We strongly recommend that set-up of the
XR24Easy is effected in a darkroom�
If the appliance cannot be set up in a dar-
kroom, then a daylight cover (24) (DL24 or
DL26) must be fitted�
• When operating an appliance with daylight co-
ver (25) please note:
Do not store films in the vicinity of a
room used to take X-rays!
When storing film material in the film de-
pot (26) of a daylight cover there is the
danger of pre-exposure� The pre-expo-
sure can be caused by the X-ray
appliance�
If necessary impose a separating wall or barrier
equipped with lead protection between�

8.2 Unpack the appliance
• Cut the plastic ties from the packaging� Lift
the box upwards and remove�
• Remove all small parts�
8.3 Prepare set-up location
• The appliance should be set-up on a stable,
flat and suitably large working surface at an
appropriate height for working at�
• In order to have access to the hoses the wor-
king surface should have at least one opening
of ca� 10x7cm�
• Take into account the need for additional
space for servicing and for sufficient ventilati-
on for the appliance:
At least 10 cm free space behind, appro-
ximately 50 cm free space to the left and
right.
Leave enough space at the front in case a day-
light cover (25) is to be used�
8.4 Set-up
• Lift the appliance at the sides and place in its
set-up position�
• The distance between the machine and the
water connection or the water drain and the
electrical safety socket should be maximum
1�5 m�
• Set up the appliance so that it has a slight tilt,
ca� 0�3° to the fixer bath (fig� 7)�
Adjust the feet of the appliance (30) using the
spanner provided (31) as required�

9. Installation
9.1 Water connections
• Check that clean, clear water flows from the
water tap (28)�
When installing for the first time make sure
the connection is allowed to flow and rinse
first!
• Turn off the water tap (28)�
• Connect the 90° elbow piece (34) to the water
tap (28), mounting the fine filter (33) (arrow in
direction of flow) and the double nipple piece
(32) at the same time�
Because the quality of water varies from
region to region we strongly recommend
fitting a fine filter (33) (order no� 1700-
008-00) between the water tap (28) and
the water hose (35)�
The fine filter (33) protects the flow regu-
lator in the water intake valve of the ap-
pliance from becoming dirty�
• Check, whether the coarse filter (35a) and
both seals (35b) are present in the threaded
pipe fittings for the water hose (35)�
• Connect the water hose (35) to the water in-
flow (36) of the appliance (threaded pipe fitting
with coarse filter) and connect to double nipp-
le piece (32)�

Problems with the waste water
flow can be avoided by keeping the
following in mind when laying the
waste water hose:
Do not let the hose hang!
Avoid squeezing or reducing the
pressure on hose!
• Apply a small amount of UHU-Plast or similar
to the outside of the hose end of the waste
water hose (37)�
• Screw the screw socket (38) onto the waste
water hose (37)�
• Fasten the drainage hose onto the connector
of the siphon trap (40) with hose clamp (39)�
• Fix the waste water hose to the wall using
hose clamp, screws and dowels�
9.3 Waste water hose connection
from developer and fixer
• Place the 10l-collector tanks (43) for develo-
per (black level indicator marker) and fixer (red
level indicator marker) below the appliance in
a clearly visible position and free from the
possibility of tilting� See also fig� 11�
• Lay the hose (41) with constant incline
• Shorten the hoses to the correct length�
• Slide the hose for developer (black marking)
through the opening of the black cover (42)�
(Fig� 13�)
• Screw the cover (42) of the collector (43) for
developer on tightly�
• Fix the hose for fixer (red markings) in the
same way to the fixer collector�
As soon as the level in the collector
reaches the level indicator markings
(43a) then the collector must be
emptied.
Danger of spilling!
