used to pull the barrier fluid into the system.
6. Open the bottle of barrier fluid and run the tubing on the inlet side so the end
near the
bottom.
Try to hold the bottle so that the bottom is at the same
level as the inlet side fitting.
7. Squeeze the handle of the vacuum pump several times. You should see the
fluid start to move from the bottle through the clear tubing into the inlet fitting.
Be patient because the fluid needs to travel through several small capillary
tubes in the assembly and past a check valve.
8. Keep working the vacuum pump to keep vacuum on the system until you see
the barrier fluid in the tubing on the outlet side.
9. Watch the fluid at the outlet (vacuum pump) side. The fluid may appear to
bubble. Large bubbles are usually due to leakage of the fitting you are using
to attach the tubing on the outlet side fitting. Small bubbles (foaming) can
happen when the vacuum is too high
– causing the fluid to boil at room
temperature. If bubbles occur, keep pumping the vacuum pump slowly. Stop
when you can see a level of fluid in the outlet side tubing (not just bubbles)
without any vacuum pressure.
10. Release the vacuum to check for a clear level of fluid in the outlet side tubing.
If there is no level restore the vacuum by pumping the pump and return to the
previous step.
11. With the vacuum released, remove the fitting with tubing from the inlet side
connection.
12.
Be sure the elbow on the inlet side won’t trap any air bubbles when you put
the pipe plug back in the fitting. To be sure you should refill the elbow with
barrier fluid by pouring fluid into the fitting opening until it is overflowing. Use
another container to catch any fluid that might spill.
13. Apply pipe dope to the pipe plug threads and tighten it into the inlet side
elbow. Remove any drips on the fitting with a rag.
14. Squeeze the handle of the vacuum pump again and allow the vacuum to
remain on the outlet side of the system for approx. 2-3 minutes, this will aid in
the evacuation of excess fluid. Once complete, release the vacuum and
remove the hand pump from the tubing (leaving the outlet side tubing in
place).

15. Check the pump to be sure that all the oil levels show full. Some pumps have
more than one type of oil (for example gear oil in one part and hydraulic oil in
