4 Discard the used oil.
Dispose of the used oil using the correct laboratory procedures.
5 Add the new oil.
Remove the oil fill cap on top of the pump and insert the funnel. Pour in the
oil until the sight glass registers between Minimum and Maximum (about 1
L). Replace the cap.
6 Tighten any loose hose connections.
7 Switch the breaker down to the I side (up) to restore rotary pump power.
See Chapter 3, “Startup, Shutdown and Status”
8 Reset the rotary pump oil clock.
See “Resetting the Maintenance Clocks” earlier in this chapter.
Once operation time has been reset it is impossible to restore its original
value. Reset with care.
Changing the Oil Mist Filter and Odor Element
The oil mist filter traps the fine oil mist preventing emission into the
atmosphere. In addition, the odor element traps odor.
Check the oil level sight on the side of the bottom filter assembly and open the
gas ballast valve to return the oil to the pump once the level has been reached.
The gas ballast valve should normally be kept open 2.5 turns to allow oil to
return to the pump naturally.
Perform the Agilent recommended method and timing when changing the
filter elements.
Perform the following procedure when changing the filter elements.
CAUTION
Use only Agilent recommended oil for the rotary pump.
