Priming

To avoid damage to the instrument, the operator should check
the quality of the operating fluid during use. If the fluid
becomes discolored, cloudy or particles appear in the reservoir,
the system should be drained and flushed with clean fluid.
1. Fit the separator to the deadweight tester using the adapter supplied, as described in
Chapter 2, above.
2. Fit the DUT to the test port of the separator.
3. Rotate reservoir dust cover through ½ turn and fill reservoir (6) approximately ¾ full
with the appropriate fluid. Rotate dust cover back to cover reservoir.
4. Open separator reservoir valve (1) one turn counter-clockwise.
5. Open deadweight tester reservoir valve one turn counter-clockwise, and turn screw
press fully in.
6. Close reservoir valves on both separator and deadweight tester, and turn screw press
fully out.
7. Open separator reservoir valve.
8. Repeat steps 4 through 7 at least three times to fully prime the deadweight tester side
of the separator chamber.
For devices with large or complex internal volumes, it may be necessary to
additionally repeat steps 4 through 7.
9. Close deadweight tester reservoir valve, turn screw press in to drive trapped air into
the separator reservoir.
Ensure that the system pressure does not exceed 15 psi / 1 bar.
10. Open deadweight tester reservoir valve, and turn screw press fully in.
11. Close deadweight tester reservoir valve, turn screw press fully out, then close
separator reservoir valve (1).
