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.
