The rubber components on the Stoppering Tray Dryer may eventually
deteriorate and require replacement. The effective life of rubber parts depends
upon both their usage and the surrounding environment. Check all rubber
hoses and gaskets and replace any that show signs of hardening, permanent set
or deterioration.

Using a soft cloth, sponge or chamois and a mild, non-abrasive soap or
detergent, clean the acrylic door.
3.
Using a soft cloth, sponge, or chamois and a mild, non-abrasive soap or
detergent, clean the exterior surfaces of the unit. Liquid spray cleaners and
polishes may be used on the exterior surfaces. Do not use solvents to remove
stains from the exterior surfaces as they may damage the finish.

1.
Every 12 months, or more often if the Stoppering Tray Dryer is operated in a
dusty environment, the refrigeration system condenser should be cleaned.
Using a vacuum cleaner with brush attachment, clean the condenser to ensure
proper airflow for peak performance.
Decontamination
When freeze drying biological substances, it may be necessary to decontaminate
the system. A surface decontaminant should be used to clean the accessible
surfaces. The use of ethylene oxide is not recommended because of its hazardous
and corrosive nature. Contact Labconco for additional information.
