Required equipment:
1 L fresh pump oil (Leybonol LVO420)
Blind flange for intake connector (DN 40 KF) or plastic cap
12 mm hexagon socket wrench
Large screwdriver
Separate power cord
Receptacle (flat) for waste oil
There is a spring valve inside the drain port. The oil will not drain until the valve is
pressed inwards with a large screwdriver, for example.
1. Turn the pump off and remove the power cable.
2.
Remove the vacuum tubing from the suction port of the
pump.
Remove the brass outer drain cap from the pump.
The inner spring valve will still be closed at this point.
4. Have a suitable container ready to catch the pump fluid as
it comes out.
Push the spring valve with a screwdriver inwards about
1 cm. The pump fluid will then start to flow from the drain.
Removing the fluid filler cap allows the used fluid to drain
from the pump faster.
To completely remove as much old fluid as possible, tilt the
pump slightly as the last fluid drains out. Remember the
pump is quite heavy.
6. Open the filler cap just above the view port with the
wrench.
Add 200 mL of fluid. Close the filler cap.
