Check The Oil-Level - Edwards RV3 Instruction Manual

More frequent maintenance may be required if the pump is used to pump corrosive or
abrasive gases and vapours, such as solvents, organic substances and acids; in these
circumstances, we recommend replacing the pump seals every year (refer to
page 51 for details of available spares). If necessary, adjust the maintenance plan
according to prior experience.
When maintaining the RV pump, use our spares and maintenance kits; these contain all
of the components necessary to complete maintenance operations successfully. The
Item Numbers of the spares and kits are given in

6.3 Check the oil-level
Note:
If required, the oil-level can be checked while the pump is operating. The pump must be
switched off and the pump and other components in the pumping system isolated from
the electrical supply before pouring oil into the pump.
Refer to
1. Check that the oil-level in the sight-glass (8) is between the MAX and MIN level
marks on the bezel of the sight-glass.
2. If the oil-level is near to or below the MIN level mark, remove one of the filler-
plugs (6) and pour more oil into the reservoir until the oil reaches the MAX level
mark. If the oil-level goes above the MAX mark, remove the drain-plug (9) and
drain the excess oil from the pump. Refit the filler-plug.
3. If the oil is contaminated, drain and refill the pump with clean oil as described in
