The Tank Level Monitor Alert occurs when the tank level remains below 90% for over 10 minutes without a volume increase. The Aquanex system should start producing RO water when the level drops below 90%. If the level does not increase, check the feed water supply, pretreatment, RO membrane, or level sensor. Ensure T2 water dispense is enabled if using the T2 dispenser or Storage Tank. Note: Type I water cannot be dispensed while Type II water is being dispensed.
