MAINTENANCE REMOVING FILTERS NOTE! Some models only. The filters for developer

MAINTENANCE REMOVING FILTERS NOTE! Some models only. The filters for developer and fixer are placed underneath a separate cover in the upper left side panel. When removing the filters for change or cleaning follow the description below. See the figure opposite. Turn the main switch off. Remove the cover for filters. If the filter is removed for exchange with a new one, unpack the replacement filter and keep a plastic bag ready for the dirty filter. Unscrew the filter lid (A) by turning it counterclockwise and slowly lift it off. The filter element (B) will hang on to the filter lid. Change the filter element (B). Be careful not to drip chemicals. Put the dirty filter into the plastic bag. Mount the filter element (B) underneath the cover (A) and lower it slowly into the filter housing to avoid splashing. Tighten the cover (A) (clockwise). The lid is tightened in two steps (C) as illustrated on the figure. When it feels tight, turn it a little more. CAUTION! Make sure the lid is tightened properly, otherwise chemicals may be pressed out of the filter housing when the replenishment system starts. Mount the cover for the filters. Turn the main switch on and press the stand-by key on the control panel. Reset filter account by pressing "OK" on display message "REPLACE DEV FILT" (or FIX) if any. See also "ALARMS" in the "FMA Control Panel" manual. NOTE! Disposal of dirty filter elements must be done in accordance with local authorities regulations. 0047 3.13 FILM PROCESSOR - GB - 550, 720, 860 55/21, 72/28, 86/34 OFF ON A B C T31137 T31137 REPLENISHMENT CHECK OF DEVELOPER REPLENISHMENT The efficiency of the developer can either be checked with a testing strip (ask your dealer of chemicals) or you can use a well exposed and well processed film as reference. If, after a week's work, the density of your film has decreased the replenishment has probably been too low and a higher setting of the replenishment rate should be selected. If, however, the density is good, the replenishment is sufficient. If desired, a lower setting can then be tried, until it is established which setting of the control is enough for satisfactory replenishment. CHECK OF FIXER REPLENISHMENT While the processor is working at its normal temperature and speed, feed an unexposed film into the processor. The film should be absolutely transparent and without whitish spots or areas spread at random over the film when it comes out of the processor, otherwise the efficiency of the fixer is too low and a higher setting of the replenishment rate should be selected. The efficiency of the fixer and the silver contents of the fixer can also be tested with a special testing strip. Ask your local specialist for application of testing strip. CHECK OF OXIDATION REPLENISHMENT If the processor is left in stand by for longer periods, this feature can be used. At the start of a new working period, check the efficiency of the developer as described above, and adjust the time replenishment rate correspondingly. 3.14 0047 550, 720, 860 - GB - FILM PROCESSOR 55/21, 72/28, 86/34 uploads/Philosophie/ user-guide-4.pdf
