Under normal operation, the Freeze Dryer requires little
maintenance. The following maintenance schedule is
recommended:
As needed:
1. Clean up all spills; remove liquids from the chamber.
2. Clean lid and gasket using soft cloth, sponge or chamois and a
mild, non-abrasive soap or detergent.
3. Check oil level of the vacuum pump. It should be between
MIN and MAX. If the oil level is less than an inch (25.4 mm)
above MIN, add oil to proper level.
4. If oil shows cloudiness, particles or discoloration, drain the
pump and replace with fresh oil.
5. Utilization of acids requires immediate cleaning and
neutralization after a run or physical damage to the
collector chamber and collector coil will result.
6. Check the collection chamber for condensed or frozen solvents
and dispose of appropriately. Completely empty the collector
chamber before the next run or before attempting to start the
vacuum pump.
7. If sample valves leak or stems become difficult to turn, pull the
stem out of the rubber valve body and apply a thin coat of
vacuum grease to the stem. Reinsert the stem into the valve
body.
