3. Place the mounting adapter on the stage rotation head and fix it
through the centre using the mounting screw (finger tight).
4. Slacken off the mount locking screw on the stage body side using
a metric 0.5 mm hex wrench, then place the stage on and over the
mounting screw.
5. Tighten the mount locking screw. The water hose connectors go
towards the rear of the chamber.
Cables and Water Hoses connection
6. The loose end of the inner cable (9-pin D-type connector) should be
installed on the corresponding connector on the feed-through plate.
Also plug the water hoses.
7. One end of the outer cable goes to the outside of the Chamber
feed-through plate on the connector labeled Cooling stage and the
other end to the rear of the CS controller.
The Water Flow Box installation and operation
8. Check that the water dam is fitted into the HiVac port in the
chamber bottom.
9. Put the Water Flow Box between the chiller and the feed-through
plate. The larger hose should connect from the chiller
Outlet to the
Flow Box input marked From Chiller . The water flow path should
make a loop between the chiller, through the water flow box and
stage, then back.
Note:
It is important to keep the water chiller away from the microscope
console to prevent vibrations.
FIGURE 9-24 CONNECTING THE WATER FLOW BOX
10. Plug the water flow box power cable but leave the power switched
off. (The other end of this cable goes to the + 24 V power supply
inside the microscope console. This should have been connected
by a service).
11. Turn on the water chiller. Water does not flow at this point, since
the valves in the Flow Box are closed when it is off.
12. Turn on power to the Flow Box. An alarm sounds, indicating that
there is no flow through the box.
13. Push and hold the Start Flow button. Keep holding this button
down until all the air is out of the water lines; this can be seen as
water flows through them. Once the lines are flowing clear, release
the button.
14. Make sure that the Flow OK light on the Flow Box is on. This
indicates that water flow is working; i.e. that there are no leaks in
the system. The light remains illuminated until there is a leak, or if
the
Stop Flow button is pressed, which could be done at any time
to close the valves and shut off the water flow, for whatever
