[25] Check the water supply FILTER. If necessary, change the FILTER.
Caution
• Any obstruction such as biological growth, small bends, or an upward sloping WASH DRAIN HOSE can cause
wash water to return to the WASH TANK causing an overflow of water and damage to the ELECTRICAL BOX
or COMPONENT PLATE.
• Concentrationsofchlorinebleach higher than 10% or allowing the chlorine bleach to remain in the PROCESSOR
for longer than 30 minutes can cause damage to the PROCESSOR.
[26] Check the WASH DRAIN for biological growth, small bends, or other obstructions. To remove biological growth
do the steps below:
a. Fill the WASH TANK and DRAIN with a 10% solution of chlorine bleach.
b. Wait a minimum of 20 minutes and a maximum of 30 minutes.
c. Drain the chlorine bleach solution and rinse the TANK and DRAIN thoroughly with water before you return
the PROCESSOR to normal use.
Warning
• Drains must be made of chemically resistant, non-corrosive material. Use PVC or the equivalent.
• The drain must have a minimum diameter of 7.6 cm (3 in.) and be free of obstruction.
• Drain service must comply with all local codes.
[27] Correctly route the WASH DRAIN HOSE down toward the WASH DRAIN. If necessary, install new
3/4 x 60 in. formed tubing, Part No. 264986.
[28] Check the DRIVE CHAIN.
(a) If the DRIVE CHAIN is dry, apply lubricant to the DRIVE CHAIN. Use NLG1 - No. 2 LITHIUM BALL and
ROLLER BEARING GREASE TL-2324.
(b) If the DRIVE CHAIN is rusty, remove it and install a new DRIVE CHAIN.
(c) Adjust the tension of the DRIVE CHAIN. If necessary, see the procedure in the Adjustments and
Replacements, Publication Part No. 5B6340.
[29] Check the operation of the DETECTOR SWITCHES. If necessary, adjust the DETECTOR SWITCHES. See
the procedures in the Adjustments and Replacements Manual, Publication Part No. 5B6340.
[30] Close the DRAIN VALVES and fill the processing TANKS with processing solutions and starter where
necessary. See the Operator Manual, Publication Part No. 5B6729, for filling instructions.
[31] Energize the PROCESSOR.
[32] Process a test film and check the PROCESSOR for correct operation.
[33] Check the negative pressure at the EXHAUST VENT for the DRYER. See the Installation Instructions,
Publication Part No. 5B6339.
Note
An AUXILIARY VENTILATION FAN KIT is available for sites that do not meet exhaust requirements.
