Troubleshooting
Accessing the Rotor in Case of Power Failure
4
5 Pull the interlock lever out and to the left (at about a 45-degree angle), and while holding it out,
step on the foot pedal.
• Depending on the level of vacuum in the chamber at the time of the power failure, the door
may or may not open.
a. If it opens, go to step 6.
b. If it does not open, you will need to manually vent the vacuum. Go to step 7.
6 After the door opens, first release the foot pedal and then release the interlock lever.
• Sample can be removed.
a. Go to step 10.
7 To vent the chamber vacuum, grasp the red rubber hose and pull it up until it comes off of the
pump fitting (see Figure 4.3).
a. Use a back-and-forth motion as you pull; this takes quite a bit of force.
• The vacuum will be completely vented several seconds after the hose is detached.
NOTE
Several tubing lines are tied to the red hose. As you grasp the hose, place your hand over
these lines. Make sure that they stay connected as you pull.
CAUTION
Do not twist the hose to the left (counterclockwise) as you pull the hose, or your
will unscrew the hose fitting.
8 Replace the hose by pushing it down over the fitting as far as it can go.
9 Pull the interlock level out and left, and while holding it out, step on the foot pedal.
10 Remove your sample.
WARNING
Never try to slow or stop the rotor by hand.
