Troubleshooting

Problem: Box is leaking.
Possible causes/solutions:
•
Normally a box will not begin to leak on its own. If none of the fittings have been modified
the leak is most likely in the gloves. Inspect the gloves closely for leaks. Replace gloves as
required.
•
Verify that all Antechambers are left under a static vacuum and are not leaking.
•
Refer to pressure test section of this manual. Record the rate of leakage.
Problem: Vacuum pump is making noise or has reduced performance.
Possible causes/solutions:
•
Change the pump oil if it looks bad.
•
Verify that all fittings connected to the vacuum pump are tight.
•
If there is no improvement after changing the pump oil and checking the fittings upstream
from the pump, put a vacuum gauge directly on the inlet of the pump. Refer to the pump
manual for obtainable vacuum. If the pump cannot obtain specified levels repair or replace
the pump.
Problem: The window is "cloudy" or scratched.
Possible causes/solutions:
•
Safety glass can be washed with alcohol. Scratches in glass are not easily repaired, especially
if they are on the inside. A glass company professional might repair scratches on the outside
of the glass.
•
Lexan, can be washed gently with mild soap or detergent using a soft cloth. Organic solvents
such as aliphatic hydrocarbons, kerosene, or naphtha may also be used. To remove light
scratches try automotive wax.
