Storage and disposal
CAUTION
Use of non-Edwards spares may result in reduced reliability and performance and will invalidate your warranty.
6.1
Storage
Use the following procedure to store the pump.
1. Place protective covers over the inlet, outlet, interstage (for the ‘i’ nEXT only), purge, booster (for the ‘T’ nEXT
only) 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. Refer to
Table 14
for recommended storage
environment. When required, prepare and install the pump as described in
Section 3
.
4. Keep the pump upright at all times to prevent the drainage of oil from the bearing reservoir.
5. 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 nEXT 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 that have been contaminated with dangerous process substances.
Take appropriate action to avoid inhalation of any particles that may be present in the pump.
Do not incinerate the pump. The pump contains phenolic and fluorosilicone materials that can decompose to very
dangerous substances when heated to high temperatures.
WARNING
In the unlikely event of a failure of the pump rotor, use appropriate personal protective equipment
when handling and disposing of the pump and ensure that all pump inlets and outlets are capped
off before disposal.
