Routine Maintenance Schedule
Under normal operation, your Purifier XT Clean Bench will require little routine
maintenance. The following schedule is recommended:
Weekly
Wipe down the interior surfaces of the clean bench with stainless steel
cleaner or 70% ethanol and allow to dry.
Using a damp cloth, clean the exterior surfaces of the clean bench,
particularly the front and top of the clean bench to remove any
accumulated dust.
Monthly (or more often as required)
Check all service valves, if so equipped, for proper operation.
Check the prefilters and replace if necessary. The prefilters should be
replaced at least quarterly.
All weekly activities.
Quarterly
Replace the prefilter. See Appendix A: XT Clean Bench Components for
ordering information.
All monthly activities.
Annually
Have the clean bench recertified by a qualified certification technician.
All quarterly activities.
