I **** told by our maintenance team that our unit (serial No. BZ559 Dec. 2023) takes distilled water due to past issues of biotic matter growing in facility water within the unit. I was told that there is a solution that is to be added to such water to destroy the biotic matter. Do you know of such a solution?
