INSTALLATION

8. INSTALLATION REQUIREMENTS

8.1 Installation site

• The Processor XR 04 must be assembled in a

dry, well ventilated room.

Never expose the Processor to direct sunlight!

With too strong sunlight pre-exposure of films and overheating of chemicals can

occur.

8.2 Installation possibilities of the

Processor

To obtain perfect development results, the installation area must be stable, flat and level.

• Assemble at or bring up to working height.

• Near a sink.

• Near a mains socket.

At a distance of approx.1.5 m from the installation site of the XR 04, there should be a mains socket for the power cable of the XR 04. The mains socket should be sited so that the

power plug of the machine is easily visible and accessible without danger.

(DIN 15990, para. 3.3.2 and 3.4)

For safety technical reasons the power connection should only be made shortly before putting the machine into operation.

Wall mounting see. pict. 1.

• Mark the position for drilling the holes for the

XR 04 (10) on the wall.

• Drill the holes, insert wall plugs and fit screws.

• Hang XR 04 on the screws, adjust as

necessary, then tighten screws.

Table mounting see pict. 2.

Fit the upper part of the XR 04 onto the edge of the table and fasten it (11).

Table installation see pict. 3.

For this assembly it is necessary to have a separate table trestle (12), (not included in the delivery schedule) Order no.1740-012-00.

9. CHANGING CHEMICALS AND WATER

Before working on opened equipment, pull out the mains plug.

• Change chemicals after approx. 200 films or

after 3 weeks at the latest.

• Change water twice a week.

The information for changing the

chemicals refer only when using "DÜRR Chemicals"."DÜRR Chemicals".

"DÜRR Chemicals".

"DÜRR Chemicals"."DÜRR Chemicals". In Germany, as well as some other countries, used x-ray chemicals are classified as special waste and must be collected separately and disposed of.

9.1 Taking off daylight attachment

Before taking off the daylight attachment: Pull out mains plug.

Push frame support (14) inwards with both thumbs. Swing daylight attachment (13) upwards and remove, see pict. 4.

9.2 Cleaning film transport

• Lift the film transport (3, Fig. 5) upwards to remove and rinse with warm water at approx. 40°C.

• If the film transport is very dirty it can be separated into two pieces and cleaned. Hereby :

• Pull the 4 snap fasteners of the film transport (16) out until they click into place.

• Using even pressure pull the top half from the bottom half (Fig. 6).

• Rinse both halves and, if necessary, clean with a brush.

Please note that when cleaning the open film transport the toothed belt can get out of position. Therefore, before reassembling the film transport check the position of the cogs (19) and the toothed belt (20) as follows:

• The transport arm (17) should be clockwise (21) clockwise (21)

clockwise (21) until it aligns with marking

clockwise (21) clockwise (21) (A).

• The film carrier (18) should now be aligned with marking (B). If not, then correct the position of the toothed belt (20):

• Fig. 7a: Hold the film transport, so that the large, white cogs cannot turn. Fig. 7b: Lift the toothed belt (20) from the cogs (19), align the film carrier (18) with marking (B). Replace the toothed belt in the correct position and press onto the teeth of the cog wheel.

Here by take care that the toothed belt sits correctly on the cog with no overlap, otherwise there is the danger that the belt comes loose from the cogs during operation.

• Place the two halves of the film transport against each other and replace the snap fasteners.

9.3 Removing heater

Only necessary with table-top model, otherwise the Developer-/Fixer containers cannot be removed.

Lift up Heater (4) and hang on frame.

9.4 Disposing of used chemicals

• Remove by rotating the 3 containers Developer (E)/Fixer (F)/Water (W) and very carefully take off downwards.

• Empty out chemical and water containers.

• Dispose of chemicals.

• Rince containers with warm water and clean thoroughly.

9.5 Mixing new chemicals

Fill containers only up to the markings. Danger of "spillage" during insertion of containers.

• Pour developer up to black marking in container (E) and then fill up with fresh water to the upper marking. Insert container and rotate to fasten.

• Pour fixer up to the red marking in container (F) and then fill up with fresh water to the upper marking. Insert container and rotate to fasten.

• Fill container (W) with white markings up to the upper mark with fresh water.

Insert container and rotate to fasten.

9.6 Assembling of the XR 04

• Replace heater (4) and film transporter (3),

see pict. 5.

• Replace daylight attachment (13).

• Put the perforated collector (6) in the water container (6), see pict. 11 and right fold-in

page.

11. REPLACING FILM TRANSPORT COGS

• Remove the locking ring of the defective cog

and pull the cog from the roller.

• Align the transport arm (A) with marking (B),

press new cog into position and secure with the locking ring.

• Place the toothed belt cog (X) onto the film

carrier roller (C) so that this appears as a D . The transport arms (A) must be aligned with

the markings (B) and the film carrier (C) shows a D shape.

• Place the toothed belt in position and

synchronise, see Point 9.2.
