10. Open the regulator shut-off valve. The pressure should stabilize after about five minutes.
If it does not, gas is probably leaking at the brass reducer fitting or at the gas port on the
rear panel of the degasser. Tighten the fittings. Then check the pressure again.
11. Open the gas bottle shut-off valve.
12. Attach an adequate length of vacuum pump tubing (that will fit over the 1/2-in. degasser
connector) to a vacuum pump and to the port labeled on the back of the degasser. Use
hose clamps to keep the hose in place. (An appropriate vacuum pump is available from
Micromeritics. Refer to Ordering Information in Chapter 4. The vacuum pump system
offered by Micromeritics includes hose clamps and tubing. Cut the tubing to the length
needed. Follow the installation instructions provided with the pump.)
