Preventive Maintenance
Daily
Empty the water buckets and wipe
out with 90% IPA or bleach, weekly
to kill any algae and bacteria.
Fill the clean water bucket with
deionized water that is 1MΩ or
better.
Check the coating reservoir to make
sure the coating level is high enough.
The coating level should be at least ½
full.
Check that the coating height is up to the
top of the coating bowl.
Check UV-Lamp hours. Replace at 1000
hours.
**Ultra Optics guarantees the UV Lamp up to 800
hours and pro rates any returns under 800.**
