5. s When processors are installed in darkroom wall openings it is most important that darkroom air pressure exceeds the air pressure of the area surrounding the darkroom This is intended to prevent air cascading through the processor into the darkroom area Proper balancing of dark lighted room air in addition to correct dryer venting will not only maximize containment of chemical fumes and vapors within the processor and its dryer exhausting system but the incidence of film artifacts occurring in the out of solution transport roller sections will be greatly reduced To prevent positive airflow from flowing back into the processor from the building exhaust there should be an air gap not exceeding more than 5 08 cm 2 0 in between the processor exhaust hose and the building exhaust thiswill benefit the site in two ways 1 The gap can be adjusted to provide correct negative flow in cases where building exhaust exceeds requirements 2 Prevent positive flow returning to the processor Colenta recommended Installation Free standing X Positive Air Pressure Stop cock Colenta page 6 8 recommended
