Over Temperature Protection
The dryer is equipped with over temperature protection in the form of a safety switch
located on one of the lamp reflectors. If temperature inside the dryer exceeds 155 f (68
C), the safety will open and remain open until the temperature drops below 105 f (41
C).
If this should happen the dryer should be checked for dirt build up, nonoperating fans
or shorted triac.
CAUTION: In no event should the processor ever be operated with this safety
device shorted or bypassed. Severe equipment and/or personal injury could occur.
Dryer Temperature Calibration
Dryer temperature should be checked by inspecting the film being processed. If the
film is exiting the dryer damp, temperature may need to be increased. If the processed
film shows heat marks (wavy horizontal lines across the film) the dryer temperature
should be reduced.
1. Inspect a piece of processed film.
NOTE: All covers and panels must be on the processor when checking operation of the
dryer.
2. Adjust trim pot R-21 as follows to adjust dryer operating temperature:
Counterclockwise = Increase Dryer Temperature
Clockwise = Decrease Dryer Temperature
3. Process another piece of film and inspect for proper drying.
