Installation
three days. State the item number of the pump together with the order number and the supplier’s invoice number.
Retain all the packing materials for inspection. Do not use the pump if it is damaged.
If the pump is not to be used immediately, replace the protective covers. Store the pump in suitable conditions, as
described in Section 6.1.
3.4 Locate the pump
Attach suitable mechanical lifting equipment to the lifting eyes on the pump.
The pump will only function correctly if installed on a level surface. 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. Ensure there is sufficient clearance for maintenance access. Refer to Figures 1, 2
and 3.
If the pump will be located inside an enclosure, make sure that there is adequate ventilation around the pump. Refer
to Figures 1, 2 and 3 for the recommended space.
Ensure that the location of the pump and the intended routing of connecting parts, i.e. process line, exhaust line and
power cables, will not present any tripping or other physical hazards.
The pumps have four rubber mounts with tapped holes in the base. It is recommended that the tapped holes are used
to mount the pump on a base frame.
3.5 Fill the pump with oil
3.5.1 Recommended pump oil
It is recommended to use the Edwards oil specified in Section 2.5 of this manual. The ultimate vacuum of the pump
with other oils may be higher than the ultimate vacuum with the recommended oil. However, note that other oils
may contain polymers which may be degraded during use so that they become thinner. Other oils, therefore, must
be changed more frequently than Edwards oils. If necessary, adjust the maintenance schedule according to
experience.
3.5.2 ES65, ES100 and ES630 oil filling procedure
Fill the pump with oil as described below.
1. Remove the oil filler plug (Figures 1, 2, and 3, item 2).
2. Pour oil into the pump until the oil level reaches the middle of the oil level sight glass
(Figures 1, 2, and 3, item 7) situated at the bottom of the pump.
3. After the pump has been running for a few minutes, recheck the oil level. If the oil level is now below the
middle of the oil level sight glass (Figure 10, item 1), switch the pump off and pour more oil into the pump as
required.
4. Refit the oil filler plug. Tighten the plug firmly but do not over-tighten.
