Safety precautions
General safety instructions
■The Cawomat 2000 IR was designed for processing medical X-ray films and
should only be used for this purpose.
■The processor may only be operated by qualified staff.
■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 cor-
rectly, 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 fit-
ted near the processor and that it is easily accessible.
■If connections with other components or assemblies are made, CAWO can
guarantee safety only for combinations which are approved by CAWO.
■If you notice conspicuous smoke or noise, disconnect the processor immediate-
ly.
■An earth leakage circuit breaker (I = < 30 mA) must be built into the electric
circuit.

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
processor 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.

Basic installation requirements
Before unpacking the unit, make sure you have a darkroom with an adequate
working area and the basic installation requirements, as listed below. Complete
specifications are provided in Appendix A.
Installation requirements
■Power requirement
Prior to connecting the processor to the mains, check whether the specifica-
tions on the data plate match your local power supply (120V / 230V). The
processor must not be run without earth protection. An earthed power outlet
protected by a fuse (15A / 16A) is required. An earth leakage breaker
(IN = < 30 mA) must be built into the electric circuit.
■Water requirement
The Cawomat 2000 IR processor does not need a separate water connection.
Water is supplied by a water replenishment bottle, and should be at normal
room temperature (15°C to 25°C / 59°F to 77°F). A convenient sink and water
hose is recommended for filling the water replenishing bottle, for mixing the
chemicals and for cleaning the processor.
An optional fixed water connection can be ordered though, if continuous water
supply is wanted. Refer to page 87 for the appropriate order code.
■Disposal of waste chemicals and waste water
It is the purchaser’s responsibility to conform to local rules and regulations re-
garding the disposal of waste chemicals. Care should be taken when handling
chemicals at all times. Please observe the hazard instructions provided on the
chemical labels.
■Ventilation requirement
The Cawomat 2000 IR processor does not require a separate exhaust system
and does not produce excessive external heat. The processor will operate prop-
erly at a room temperature between 15°C and 30°C / 59°F and 86°F, and at a
relative humidity between 30% and 80%.

1220C GB 19991004
Working area requirements
The Cawomat 2000 IR is designed to be installed in a darkroom. Consult the
medical imaging film company for recommended darkroom lighting conditions.
The counter or support upon which the processor is to be set up must have a
minimum surface of 660 x 660 mm. A larger working surface is recommended
for safety purposes. The processor should be accessible from all sides if possi-
ble, but a minimum clearance must be provided. Consult the diagram:
The Cawomat 2000 IR Support Table
is an option meeting exactly all re-
quirements: it features appropriate
support leg holders and a hole to
lead through the drain hoses to the
waste bottles which can be placed in
a safe location underneath the table.
❖Refer to Appendix A for order codes
and specifications.

❖Refer to page 21 for a diagram of the main components.
Arranging the drain hoses
1Remove the rubber bands.
Lift the processor and set it down on its rear end with two people. Do not use the legs as
a pivot point. The drain hoses are held in place by rubber bands.
2Withdraw and unroll the three drain hoses.
If the processor has been placed as shown above, you see from the left to the right: the
developer hose, the fixer hose and the wash-water hose.
3Lower the processor back into operating position with two people.
Do not use the legs as a pivot point.

1220C GB 19991004
4Arrange the hoses into their appropriate waste bottles.
Waste solutions must be drained preferably into three separate waste bottles. The devel-
oper hose and the waste-water hose can be put together into one bottle. However, the
fixer hose should be put into a second waste bottle.
5Correct the hose length.
If the processor is to be installed on a counter with the waste bottles stored beneath,
holes should be cut into the counter top for the drain hoses to pass through.

1220C GB 19991004
Levelling the processor
The processor must be exactly level for a reliable operation and a proper replen-
ishment of the chemicals. Levelling screws in the legs are provided to enable a
proper adjustment. Use a levelling instrument to achieve satisfactory results.
1Level the machine by means of the adjustable legs.
Level the machine front-to-back and left-to-right, preferably on the tank rollers as shown
in the figures above.
– Turn the levelling screws clockwise to raise the processor and counter-clockwise to
lower the processor.
– Turning the screws is made easier by lifting slightly the appropriate corner.
2Now you can replace the processor cover.
Make sure that the interlock pin, marked on the processor cover with a white dot, is prop-
erly engaged with the interlock switch. If not, the processor will fail to work.

Inserting the replenishment bottles
A set of replenishment bottles was packaged in the accessories box that also
contained this manual. Supplementary sets of 5 l or 2.5 l replenishment bottles
can be ordered to assure quick changing of the chemicals. Refer to the
Appendix A ‘Equipment information sheet’ for the appropriate order codes.
1Make sure the replenishment bottles have the correct valves attached.
The valves are color coded to match them to their corresponding bottles to avoid conta-
mination of the chemicals. Refer to the table on page 36 for the appropriate color codes.
❖Never interchange the valves!
2Insert the empty replenishment bottles into the corresponding receptacles.
❖The replenishment bottles should be inserted emptily at this time. The mixing and filling
procedure for chemicals can be found in chapter 2, ‘Getting started with the Cawomat
2000 IR’.
