6 STORAGE AND
DISPOSAL
6.1 Storage
Use the following procedure to store the pump.
1. Place protective covers over the inlet, outlet,
interstage (EXT555Hi only), purge and vent
ports.
2. Place the pump in its packing materials. For
fastest pump-down when the pump is put back
into service, seal the pump inside a plastic bag
together with a suitable desiccant.
3. Store the pump in cool, dry conditions until
required for use. When required, prepare and
install the pump as described in Section 3.
4. Avoid long-term storage if possible. When long-
term storage is necessary, the pump should be
set up and run for at least eight hours every six
months.
6.2 Disposal
Dispose of the EXT555H Turbomolecular Pump and
any components and accessories safely in
accordance with all local and national safety and
environmental requirements.
Particular care must be taken with any components
which have been contaminated with dangerous
process substances.
Take appropriate action to avoid inhalation of any
particulates which may be present in the pump.
Do not incinerate the pump. The pump contains
phenolic and fluorosilicone materials which can
decompose to very dangerous substances when
heated to high temperatures.
