Your RO is designed to operate on softened tap feed water with an SDI of 5 or
less. The pH should be in a range of 5.5 - 8.5. Exposure to any levels of chlo-
rine may cause irreversible damage to the Thin-layer composite (TLC) polyamide
(PA) membrane elements in your machine. Daily water checks are recommend-
ed to ensure the integrity of your pretreatment and RO system. Refer to
Table 2.2 (E2/EZ2-Series Feed Water Requirements).
2.8.2 Machine Start-Up Preparation

your water softener and activated carbon filters have been leaked checked and
properly flushed, before starting up your RO machine.
