Unger DIUB3 HydroPower Ultra L and LC resin pack — complete refill in one operation
The DIUB3 pack contains the 3 ion-exchange resin cartridges required for a complete refill of the HydroPower Ultra L (DIUH2) and the HydroPower Ultra LC (DIUH3). Both systems have 3 cartridge positions — when the resin is exhausted, all 3 cartridges must be replaced to restore full pure-water production performance.
When should it be replaced?
The integrated digital TDS meter in the Ultra L and Ultra LC continuously indicates the quality of the water produced. When the value exceeds 10 ppm, this indicates that the resin is exhausted and the complete DIUB3 pack must be replaced. Cleaning with water above 10–15 ppm starts to leave visible marks as it dries.
Compatible exclusively with DIUH2 and DIUH3
The DIUB3 is specifically for the Ultra L and Ultra LC models. It is not compatible with the Ultra S (DIUH1), which uses the individual DIUBS cartridge.
| System | System reference | Resin replacement |
|---|---|---|
| HydroPower Ultra S | DIUH1 | DIUBS (1 cartridge) |
| HydroPower Ultra L | DIUH2 | DIUB3 (3 cartridges) |
| HydroPower Ultra LC | DIUH3 | DIUB3 (3 cartridges) |
