the syringe plunger clamp. This is
achieved by using weights.
9 Plunger clamp Close the clamp at mid-position. Front edge of clamp must be between
alignment. Run an infusion of at least 99.9 ml/h. 8 and 10 mm above surface of top cover.
After 5 seconds check clamp position. See page 6-5,
Fig. 6.4 Taper Gauge.
Note:
If this test fails then the super nut will have to be loosened, this will allow the plunger clamp to be
manipulated up or down a small distance, thus enabling the required 8.0 to 10 mm gap to be achieved.
