System Maintenance - Replacing DI Resin

NOTE: Unger does not recommend the use of bulk resin with nLite HydroPower

systems. The use of bulk resin, with its widely varying properties, may cause

damage to the system due to excessive expansion when water is introduced.

Overlling the system will also cause damage.

Unger’s pre-measured QuickChange

Replacement Resin Bags are designed to allow

controlled resin expansion within a designed safety limit.
