6 Maintenance and Troubleshooting
4. Remove one end fitting from the trap body and dispose of the used alumina in an appropriate
manner.
5. Wash the trap body with a detergent-based soap. Rinse with water, then rinse with isopropyl or
ethyl alcohol. Set the trap aside and allow to dry thoroughly.
Exposure of the trap body to oil vapor may cause small cracks on the
inside surface of the trap body. Under normal circumstances, these
cracks will not cause problems or leaks.
Prepare fresh alumina
1. Preheat the oven to 300 °C.
2. Pour approximately 180 grams of fresh alumina into a glass or metal container (approximately 250
mL if a graduated beaker is used). Place the container in the oven.
3. Bake the alumina for two hours at 300 °C.
4. Remove the baked alumina from the oven and allow to cool until luke warm. A desiccator may be
used to speed the cooling process.
5. Use a small spatula to gently pry the O-ring from the end fittings of each end of the trap body.
