Maintenance Program

Monthly Cleaning

All rack assemblies and tanks must be cleaned thoroughly every month. This procedure may take up to
two hours.
Caution!
Make sure unit is turned off before performing monthly cleaning.

1. Clean the DEV, FIX, WASH racks

A. Open the drain valve to remove the developer, fixer and water from tanks.
B. Remove the racks from the unit and clean the racks. (Follow weekly cleaning procedure on page 5)
C. Remove all drain filters and rinse them with lukewarm water.
D. Check the condition of each rack and rack side plates. Rotate rollers, by turning worm wheel (Gear)
in one direction, to make sure rotation is smooth.
Note: Fixer rack has a higher potential for damage than the developer rack. This originates from the
chemical reaction of the fixer. Therefore, the conditions of the fixer rack (rollers, gears, guides,
side plates and bushings) must be checked thoroughly and frequently.

2. Clean the DEV, FIX, WASH tanks and OVER FLOW line

A. With racks out of the tanks, close drain valves and pour lukewarm water into the tanks. With a soft
brush clean the base and walls of each tank. Once finished, open drain valves to remove water.
B. Pour lukewarm water into the overflow hole to remove foreign substances.
C. Once you have cleaned all the tanks, make sure to close the drain valves, fill each tank with
lukewarm water then mount all the racks and turn the unit on. You should run the processor for
approximately 15 minutes while you are checking the circulation of the water and the operation of
each rack.
D. Once this is complete drain the water and follows procedures for filling chemistry. (Page 10)
