4-1. The aquaMAX
TM
-Ultra maintenance
- To keep the water quality of feed water
: Feedwater for Ultrapure water system should be R.O(Reverse Osmosis) grade water or D.I(Deionized) water.
Therefore, to use filter longer, the feedwater needs to be fresh and kept in good condition.
- Periodic operation
: If the system keeps power on, it can increase the time of use because recirculation runs every 1 hour.
4-2. Filter safekeeping
For Ultra Pack or UF Filter : If the system is not used for a long time, keep the water inside of filter and close
the input and output with the cap. Keep the air out of filters. When it comes to using again, run “ stabilization”
on service menu a few times to remove air or contaminants. Keep the UV lamp in the safe place.
