Monthly:
1. The rubber components on the Freeze 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.
2. Using a soft cloth, sponge or chamois and a mild, non-abrasive
soap or detergent, clean the acrylic chamber lid.
3. Using a soft cloth, sponge, or chamois and a mild, non-abrasive
soap or detergent, clean the exterior surfaces of the Freeze
Dryer. 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.
Annually:
1. Every 12 months, or more often if the Freeze 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.
