The equipment shown in this section may differ slightly from yours.
However, the process is the same unless otherwise noted.
The activated alumina in the oil vapor trap becomes saturated during use. The alumina should be
inspected periodically and replaced when most of the alumina pellets are no longer white.
Do not perform the following procedure on used alumina. The resultant
oil vapors may cause a fire.
1. Disconnect the vacuum pump from the analyzer and place it on a work table.
2. Loosen the wing nut on the clamp at the top of the oil vapor trap. Swing the clamp open and
remove the trap from the hose.
3. Loosen the wing nut on the clamp at the bottom of the oil vapor trap. Open the clamp and remove
the trap.
