Fan Filter Unit IOM FFDE, FFDER, FFDERA Models I N S TA L L AT I O N & O P E R AT I O N M A N U A L Testing Each fan filter unit is thoroughly tested at the factory before shipment. However, because of the “rigors” of shipping, Titus encourages units are re-tested after installation. Titus recommends that the customer contact an independent organization, with technicians trained and experienced in performance evaluation and maintenance of clean air equipment.
