INSTALLATION

8. INSTALLATIONREQUIREMENTS

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 offilms and overheating of chemicals canoccur.

8.2 Installation possibilities of the

ProcessorTo 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 theinstallation site of the XR 04, there should be amains socket for the power cable of the XR 04.The mains socket should be sited so that thepower plug of the machine is easily visibleand accessible without danger.

(DIN 15990, para. 3.3.2 and 3.4)

For safety technical reasons the

power connection should only bemade shortly before putting the

machine into operation.

Wall mounting see. pict. 1.

Mark the position for drilling the holes for theXR 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 edgeof the table and fasten it (11).

Table installation see pict. 3.

For this assembly it is necessary to have aseparate table trestle (12), (not included in thedelivery schedule)

9. CHANGING CHEMICALSAND WATER

Before working on opened

equipment, pull out the mains plug.

Change chemicals after approx. 200 films orafter 3 weeks at the latest.

Change water twice a week.

The information for changing thechemicals refer only when using"DRR Chemicals"."DRR Chemicals"."DRR Chemicals"."DRR Chemicals"."DRR Chemicals".In Germany, as well as some othercountries, used x-ray chemicals areclassified as special waste and mustbe collected separately and disposedof.

9.1 Taking off daylight attachmentBefore taking off the daylight

attachment: Pull out mains plug.

Push frame support (14) inwards with both

9.2 Cleaning film transport Lift the film transport (3, Fig. 5) upwards to

remove and rinse with warm water atapprox. 40C.

If the film transport is very dirty it can beseparated 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 fromthe bottom half (Fig. 6).

Rinse both halves and, if necessary, cleanwith a brush.

Please note that when cleaning theopen film transport the toothed beltcan 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 turnedturnedturnedturnedturnedclockwise (21)clockwise (21)clockwise (21)clockwise (21)clockwise (21) until it aligns with marking(A).

The film carrier (18) should now be alignedwith marking (B). If not, then correct theposition of the toothed belt (20):

Fig. 7a: Hold the film transport, so that thelarge, white cogs cannot turn.

Fig. 7b: Lift the toothed belt (20) from thecogs (19), align the film carrier (18) withmarking (B).Replace the toothed belt in the correctposition and press onto the teeth of the cogwheel.

Here by take care that the toothed beltsits correctly on the cog with nooverlap, otherwise there is the dangerthat the belt comes loose from thecogs during operation.

Place the two halves of the film transportagainst each other and replace the snapfasteners.

9.3 Removing heaterOnly necessary with table-top model,otherwise the Developer-/Fixercontainers 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 verycarefully take off downwards.

Empty out chemical and water containers.

Dispose of chemicals.

Rince containers with warm water and cleanthoroughly.

9.5 Mixing new chemicalsFill containers only up to the

markings.

Danger of "spillage" during

insertion of containers.

Pour developer up to black marking incontainer (E) and then fill up with fresh waterto the upper marking. Insert container androtate to fasten.

Pour fixer up to the red marking in container

(F) and then fill up with fresh water to theupper marking.Insert container and rotate to fasten.
