Connecting or Replacing Valve Inlet Tubing
Flexible tubing connects the valves to the gas manifold inside the degasser. If there is no gas
flow to a particular valve, the tubing could be disconnected. To check the tubing:
1. Place the vacuum pump power switch in the OFF position and remove the vacuum pump
tubing.
2. Remove the rear panel by removing the six screws that secure it.
3. The tubing should be connected to the valve and to one of the spokes on the manifold. If it
is disconnected at either end, connect it by pressing firmly into place. If a spoke on the
manifold is loose, tighten it finger-tight plus 1/2 turn with a wrench. Do not overtighten
because the gasket may become forced out of place. The fitting would then leak.
4. Replace the rear panel and vacuum pump tubing.
5. Place the vacuum pump power switch in the ON position.
Calibrating the Vacuum Gauge
If the vacuum gauge displays an inaccurate vacuum level, recalibrate the gauge by following
the steps in Calibrating the Vacuum Gauge, page 1-13.
