Preventative Maintenance
Perform preventive maintenance to ensure that your Vacuum Degasser will per-
form consistently at an optimal level. To maintain the Vacuum Degasser in the
best condition, the following measures are recommended:

Adhere to standard laboratory cleanliness practices.
Use only high-purity titrants - preferably High Performance Liquid Chroma-
tography (HPLC) Grade. Water should be bottled HPLC Grade, or filtered
and deionised tap water.
Filter all titrants to prevent particulate contamination and tubing blockages.

Use only high-purity gases when drying contact areas.
Follow the short- and long-term shutdown procedures that are described
above.

Routine cleaning of the external surfaces of the instrument can be done using a
clean, damp cloth. Immediately clean any spills which occur on or near the
instrument using methods appropriate for the type of spill. Some titrants can
damage the appearance and function of the instrument.
Routine Maintenance
Routine maintenance is defined as replacing the normal wear items when degrada-
tion in performance is noticed.
Consult the Troubleshooting Guide, below, if a problem has arisen.
Warning!
Never remove the Degasser's cover. There is nothing inside that requires
customer service or maintenance.
