6 Storage and Disposal
6.1 Storage
Observe the storage temperature limits stated in Section 2.1. Storage below -30 ºC will permanently damage the
EH pump seals and lubricants.
Ensure that the water lines are emptied if the pump will be stored below 0 ºC. If not, the water in the lines will
freeze and may cause the pipes to burst. If the pump is to be shipped by air, it is important that the lines are
completely emptied of water.
Use the procedure below to store the EH pump.
1. Shut down the EH pump as described in Section 4.3.
2. Isolate the EH pump from the electrical supply and disconnect it from the vacuum system.
3. Clean the EH pump and change the oil as described in Section 5.5.
4. Place protective covers over the inlet and outlet flanges.
5. Store the EH pump in cool, dry conditions until required for use. When required, prepare and install the EH
pump as described in Section 3.
6.2 Disposal
Dispose of the pump and any components removed from it safely in accordance with all local and national safety and
environmental requirements.
Take particular care with components and waste oil which have been contaminated with dangerous process
substances.
The instrument and associated cables are within the scope of the European Directive on Waste Electrical and
Electronic Equipment, 2002/96/EC. Edwards offers European customers a recycling service for the instrument/cables
at the end of the product's life. Contact Edwards for advice on how to return the instrument/cables for recycling.
