*Oil-sealed vacuum pumps only.
**For oil-free pumps only: After about 12 to 18 months of operation, the diaphragm in the pump will
wear out. When the diaphragm wears out, the pump becomes completely inoperable. To prevent any
instrument down time due to an inoperable pump, we recommend that you have the diaphragm
replaced by a Micromeritics Service Representative every 12 months.
