6 Routine Maintenance
Regular preventive maintenance will help to reduce box problems that cause down time and
increase the overall performance of the system. Different environments require different
maintenance intervals, but the following are the recommended minimum levels of service
required.
6.1 Daily Tasks
•
Check the gloves for wear or holes. Check that they are seated properly and that the exterior
“O” rings are in place. Replace worn or defective gloves or “O” rings as soon as possible.

•
Inspect the exterior of the system. Ensure that it is kept free from excessive dirt. Check that
the piping is intact and that all gas supply and vent lines are well connected. If necessary,
clean the exterior. Tighten any loose connections.
•
Check that the gas supply is sufficient and the flow is adequate. If necessary, replace the gas
supply and adjust the flow rate.
6.2 Weekly Tasks
•
Check and replace, if necessary, the vacuum pump oil. This step is crucial to the life of the
pump and its ability to perform to specifications. Because each pump is different, refer to the
pump manual for service procedures.
•
Check the ante chambers “O” rings. Replace them if they are worn.
•
Check the box filters. Replace if necessary.
6.3 Annual or Semi Annual Tasks
•
If the purification capability of the column is not sufficient (it can no longer maintain low
oxygen and moisture levels), regenerate the filter column material.
•
If time between regenerations has become minimal, replace filter column material.
•
Replace box filters.
6.4 Safety Inspections
•
Inspect all box wiring for signs of wear or damage. Replace any suspect wiring found during
the inspection.
•
Inspect the window for signs of stress or cracks. Replace as needed.
•
Never place or stack materials, tools, or documentation on any part of the Glovebox exterior
surfaces except for those that are designed for such purposes. Vibration or contact with
people or other objects may cause the items to fall.
Follow all of the routine maintenance tasks listed in this section.
