Locate the pump
Attach your mechanical lifting equipment to the lifting eyes on the pump.
Provide a firm, level platform for the pump. Locate the pump so that the oil-level sight-glass is visible and the oil
filler-plug, oil drain-tap, disposable oil-filter and gas-ballast control are accessible.
If your pump will be located inside an enclosure, make sure that there is adequate ventilation at both ends of the
pump, so that the ambient temperature around the pump does not exceed 40°C. There must be a minimum space of
25 mm between the pump and the enclosure walls.

Fill the pump with oil
3.5.1
Recommended pump oils
When the ambient temperature is 12°C or higher, we recommend that you use Edwards Ultragrade 70 oil. This tested
and proven oil will give you the best performance, maintenance intervals and pump life. Otherwise, use another oil
with the specification VG ISO 68.
If you pump oxygen or other dangerous gases and vapours, you must use a chemically inert and stable oil (such as
perfluoropolyether). For information on pumping dangerous gases and vapours, refer to the Edwards guidelines on
vacuum pump and vacuum system safety (see Associated Publications at the end of the contents list).
WARNING
Use suitable lifting equipment to move the pump. The mass of the pump is between 70.5 kg and
105 kg.
WARNING
If you use a hyrdocarbon oil in this pump, you must not use the pump to process oxygen in
concentrations greater than 25% in volume. If you do, there is a risk of fire or explosion in the
oil-box of the pump.
