NVO489UFHEDP
1” Porting, High-Hardness, High-Performance
Designed to soften extremely hard water (>75 gpg), the 489UFHEDP’s dual-tank system offers a more cost-effective solution than larger single-tank systems. Featuring 1” porting, the HEDP’s first resin tank significantly reduces water hardness and the second tank acts as a ‘polisher’ to prevent hard water slippage. The HEDP’s high-efficiency technology uses less salt while supplying consistent soft water.

Key Features
Upflow Regeneration:
Saves salt by preserving the unused portion of the softening bed from unnecessary ion exchange.
Precision Brining:
Calculates the exact amount of brine required to regenerate, using up to 30% less salt.
Automatic System Refresh:
If no water is used for seven (7) days, the system will perform an automatic refresh to prevent bacteria growth.

Save water each regeneration by skipping up to ten (10) backwash cycles on clean municipal water supply.
Soft Water Brine Tank Refill:
Keeps tank & injectors clean.
Soft Water Recharge:
If capacity goes below 3%, an automatic 15-minute recharge restores softening until the next regeneration.
