Safety precautions
General safety instructions
• The processor was designed for processing medical X-ray films (except for mam-
mographic films and rollfilms), and should only be used for this purpose.
• The processor may only be operated by qualified staff, skilled on the machine.
• Make sure that only authorized personnel has access to the processor.
• Only trained and authorized service personnel can make repairs or changes to the
processor.
• If there is visible damage to the machine casing, the processor should not be
started or used.
• Do not override or disconnect the integrated safety features.
• Disconnect the processor from the mains before performing any maintenance
activities.
• Like all technical devices, the processor must be operated, cared for and ser-
viced correctly, as described in the documentation provided with the machine.
• If the processor is not operated correctly or if you do not have it serviced correctly,
CAWO is not liable for resulting disturbances, damages or injuries.
• When installing the processor, care must be taken to ensure that there is either a
mains plug or an all-cable disconnecting device in the internal installation fitted
near the processor and that it is easily accessible.
• If connections with other components or assemblies are made, CAWO can guar-
antee safety only for combinations which are approved by CAWO.
• If you notice conspicuous smoke or noise, disconnect the processor immediately.
• An earth leakage breaker must be built into the electrical circuit (I
≤ 30 mA).

Special instructions for the handling of chemicals
• When handling chemicals, you must observe safety and environmental regula-
tions as well as the operating and warning instructions accompanying the chemicals.
• Wear stipulated protective clothing and safety goggles.
• When disposing of chemicals and waste water, you must comply with the local
regulations concerning waste water and environmental protection.
• If chemicals get into your eyes, immediately rinse your eyes with cold water and
consult a physician.
• Do not inhale vapor from chemicals. Make sure that there is sufficient ventilation
where the processor is installed, i.e. air exchange that is at least ten times the
space volume per hour.
• Always comply with the installation instructions.
• Regularly check all connections to the processor for tightness.
• If liquid gets into the inside of the processor (due to spills), disconnect the proces-
sor from the mains immediately and have the device cleaned thoroughly by
service personnel.
Collect spent chemicals in
separate containers and
suspend hose pipes at a
sloping angle without any
kinks.
Make sure that the hose pipes do not come into contact with the liquid in
the container!
Do not use additional chlorine or chlorine containing substances inside the
processor. The use of additional chlorine or chlorine containing substances
can lead to irreversible damage of the equipment. Using these substances
may void the manufacturers warranty.

Feeding a film to the Cawomat 2000 IR
Do not put films on or near the dryer! Films can get fogged when placed on
the dryer.
❖
You should first run a cleaning film if the machine has been standing idle for
some time.
1 Push a film into the feed slot until the LED in the replenishment key shows a red
light.
• The maximum film width is 35 cm.
• The smallest size that can be processed is 10 x 10 cm or 9 x 12 cm. Films of this
size have to be fed diagonally.
Use this key to adjust the dryer.
❖
Do not process rollfilms nor mammographic films!
2 You can feed the next film when the LED goes out.
Films are processed for about three minutes and then discharged at the front and
placed on the receiving tray.

Replenishment
Preparation of chemicals
❖
Only use ready-packed concentrates (G 153, G 353 or G 354) that are suitable for machine processing.
1 Clean the replenishment bottles with tap water prior to filling them with fresh
chemicals.
2 Carefully follow the preparation instructions on (or in) the packages.
3 Fill the replenishment bottles with freshly prepared solutions only.
The replenishment bottles are distinguished by valves of different colors:
• Developer : red
• Fixer : blue
• Water : white
4 Place the bottles in the identically colored openings.
1221G EN 20070801
The tanks are filled automatically.
You are reminded to handle all chemicals with care, to wear protective gloves and an
apron to protect your clothing, and to wea r protective glasses for your safety. Always
conform to local regulations regarding the disposal of chemical s .

Additional replenishment
If the machine has been left idle for more than about one day you should briefly
press the replenishment key once.
Use this key to activate an additional replenishment.
0
Wait about three minutes, until the LED goes out, before feeding the next film.
Replenishment rates
The Cawomat 2000 IR processor features an automatic replenishment system,
in which the replenishment cycle is controlled by the length of the film. The
replenishment pumps have been factory-set for average replenishment rates
based on processing 240 x 300 mm films. If you will be processing either mainly
larger or smaller sizes, it will be necessary to adjust the pumps.
Checking the replenishment rates is required in the following circumstances:
• After installation of the machine.
• After replacement of the pumps.
• If the standard film size is altered.
18
❖
Each of the three replenishment bottles has its own replenishment rate.
Refer to the Cawomat 2000 IR reference manual for detailed procedures on
how to check and adjust the replenishment rates.
You are reminded to handle all chemicals with care, to wear protective gloves and an
apron to protect your clothing, and to wear protective glasses for your safety. Always
conform to local regulations regarding the disposal of chemicals.

Drain and clean the wash-water tank.
If weekly processing is less than 80 films, drain and clean tanks
and replace spent chemicals in the replenishment bottles.
If weekly processing is more than 80 films, perform the above
tasks every two weeks.
Clean the squeegee rollers (dryer assembly).

General cleaning directions
❖
We refer to the Reference manual for a description of the cleaning procedure.
When cleaning the Cawomat 2000 IR, always take into account the following
points:
• Always disconnect the power cord from the outlet.
Do not work with wet fingers!
• Never use hot water. The highest temperature allowed is 40 °C.
• Avoid contact with chemicals.
• The electric wiring to the tank heaters is permanent. Do not disconnect the wires.
• Never clean the machine chassis and plastic parts of the tank heaters in running
water. Always wipe off with a damp cloth!
Do not use additional chlorine or chlorine containing substances inside the
processor. The use of additional chlorine or chlorine containing substances
can lead to irreversible damage of the equipment. Using these substances
may void the manufacturers warranty.
The replenishment bottles, bottle valves, bottle receptacles, tank covers, pumps
and tanks are color-coded to prevent contamination of the chemicals and for
ease of assembly after cleaning. They must be returned to their proper location
after cleaning.

Troubleshooting
In this document only the basic troubleshooting actions are mentioned. We refer
to the Cawomat 2000 IR Reference manual for a detailed overview of what to do
in case of film or machine faults.
❖
In case of faults it is advisable to turn the machine off briefly, and then on
again. This may correct the problem.
Do not work with wet fingers!
Possible corrective actions for film and/or machine faults:
• Check that the dryer assembly cover and the processor cover are firmly in place.
• Check the replenishment bottles and tanks, and if necessary, replace the fixer and
developer chemicals.
• Check and clean the feed tray, the exit tray, the tanks, the rollers, the pump drive
system and the pumps.
• Check that the machine is level.
• Check and if necessary adjust the replenishment rates for the chemicals and the
dryer temperature.
❖
If necessary, call technical service.
Do not put films on or near the dryer! Films can get fogged when placed on
the dryer.

Exposed film is inserted directly into the feed slot at the left side of the processor. The film passes the film scanner regulating the replenishment and dryer
systems, and then passes through the developer, the fixer and the wash-water
tanks. After drying, the film leaves the dryer section and is deposited on the exit
tray.
