3.4 Locate the pump
The pump can be either free-standing on its baseplate, or be fixed by bolts through the four fixing holes
in the baseplate, or be used with vibration isolators. For the locations of the fixing holes in the baseplate,
refer to Figure 2.
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-plugs 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
o
C. There must
be a minimum space of 25 mm between the pump and the enclosure walls.
3.5 Fill the pump with oil
Fill the pump with oil as described below. Refer to Figure 1 for the item numbers in brackets.
1. Remove the oil filler-plug (1).
2. Pour oil into the pump until the oil-level reaches the MAX mark on the bezel at the top of the oil
sight-glass (12). If the oil-level goes above the MAX mark, remove the oil drain-plug (11) and drain
the excess oil from the pump.
3. After a few minutes, recheck the oil-level. If the oil-level is now below the MAX mark, pour more
oil into the pump.
4. Refit the oil filler-plug. Tighten the plug firmly by hand. Do not overtighten.
WARNING
Use suitable lifting equipment to move the pump. If you do not, you can injure yourself
or damage the pump. Refer to Section 2.3 for the mass of the pump.
