Under normal operation, the CentriVap requires little maintenance. The
following maintenance schedule is recommended. Before servicing the
CentriVap, disconnect electrical power. Special precautions must be observed if
materials used in the CentriVap Concentrator are known to be hazardous, toxic,
radioactive or contaminated with pathogenic micro organisms. Before servicing,
the CentriVap Concentrator must be suitably decontaminated. Wear appropriate
eyewear, gloves and other safety apparel.
As needed:
Before using any cleaning or decontamination method except those recommended
by the manufacturer, users should check with the manufacturer that the proposed
method will not damage equipment.
1. Clean up all spills; remove liquids from the chamber. Clean or decontaminate
all surfaces using agents suitable for the substance spilled.
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, if applicable. 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 collection chamber will result.
6. Check the Cold Trap for condensed or frozen solvents and dispose of
appropriately. Completely empty the trap before the next run. The Cold Trap
cover is removed by first lifting and rotating the two retainers that secure the
lid in place. If solvents are frozen in the glass trap, run it under cold water
immediately after operating.
NOTE: IF THE ICE HAS MELTED, THE GLASS TRAP INSERT MUST
BE EMPTIED BEFORE THE COLD TRAP IS STARTED AGAIN.
