To reattach the skimmer cone and sampling cone, complete the following
steps:
1 Reattach the skimmer cone.
Using the skimmer wrench, screw the skimmer cone into the interface
opening. Tighten the cone with the skimmer wrench (Figure 68).
2 To install the sampling cone, complete the following procedure:
It is important that the sampling cone is not over tightened when installing
it on the interface housing.
1 Install the sampling cone on the interface housing without the O- ring.
2 Hold the sampling cone by its outer perimeter and turn clockwise,
tightening the cone until it contacts the interface housing.
3 Draw an alignment line on the sampling cone and the edge of the
interface housing using an indelible marker. This mark indicates the
correct tightened position of the cone on the interface housing after the
O- ring has been attached.

4 Remove the sampling cone from the interface housing.
CAUTION
If the sampling cone and the skimmer cone are not tightly installed in the base, the
skimmer cone is not cooled, the tip melts, or the vacuum does not reach the standard
value and it cannot change to Standby mode. Firmly install the sampling cone and the
skimmer cone.
