Yes, you can hook an ice maker to RO water — just get the pressure right.

You can connect your ice maker to an RO system, and it won’t damage the machine if your RO setup has a storage tank.

The fear that pure RO water will eat the ice maker from the inside is mostly overblown. Modern ice makers use plastic and stainless steel that handle low-TDS water fine. The water actually freezes into clearer ice because there’s less trapped air and dissolved solids.
