CS8H Water Softener – Volumetric Metered-Time Control | 4.5, 11, 15 Lt Resin

CS8H Water Softener – Automatic Metered-Time Control

The CS8H water softener combines simplicity with professional-grade performance. Its volumetric valve supports four regeneration modes — making it ideal for residential use from 1 to 4 people. Available in 4.5 lt, 11 lt, and 15 lt resin versions.

Regeneration Modes

• Time Delayed – Regeneration triggered at a scheduled frequency
• Meter Immediate – Regeneration starts after treating the programmed water volume
• Meter Delayed – Volume-based regeneration triggered at a set hour
• Mixed Time/Volume – Combines scheduled and volume-based regeneration for maximum efficiency

Key Benefits

• Eliminates limescale — protects pipes, boilers, and appliances
• Energy saving: prevents scale deposits in hydraulic lines
• Cost saving: reduces soap, detergent, and maintenance costs
• Softer skin and hair during showers
• Fully automatic — just top up the salt
• Bypass valve and hardness mixing valve included

Installation Requirements

Three water pipe connections (inlet, outlet, drain) and a standard power supply. No specialist tools required.

How to Choose the Right Size

Divide your resin exchange capacity by your water hardness (°F) to get the litres treated per cycle. Example: 15 lt resin at 40°F → 140 ÷ 40 = 3,500 lt per regeneration cycle. For a family of 4 consuming ~150 lt/person/day at 40°F, the 15 lt model regenerates every 5–6 days.
