EC4 Series Features

Immediate Condition Response

Push any button and the EC4 wakes up to display the system status with any applicable instructions or messages.

Power Outage Recovery

If power is lost during the regeneration process, the EC4 will automatically recover and complete the process once power is restored. This feature ensures that all scheduled regeneration cycles are never missed, and that soft water is always available.

Distinctive Alarm Tones

The EC4 supports three different alarms — low salt, no salt, and when service is required.

Large Interactive Display

The EC4 provides easy-to-read and understandable system information via a two-line LCD display. Messages scroll across the

display, identifying the menu being accessed.

Information Center

Simple access to the EC4’s Information Center menu provides the customer with information about their system, water

quality, usage profile and general support data. Aids both the customer and the dealer when troubleshooting the unit.

Proportional Brine and Rinse

Overall system efficiency is achieved with RainSoft’s proportional brining feature. Saves on overall salt and water consumption with shorter regeneration cycles based upon specific household water usage.

How the EC4 Water Conditioner Works

Step 1: Water enters RainSoft’s exclusive rugged control valve and flows down through the EC4 resin tank.   Step 2: The water is filtered and treated as it passes through the special “ion exchange” resin. Hardness ions are ionically retained in and on the resin. The optional carbon bed further polishes and clarifies the water.   Step 3: Once completely conditioned, the water exits the resin tank through the riser pipe and out the control valve.   Step 4: At metered intervals, the unit begins a regeneration process. Using salt as a regenerant, the retained hardness ions are flushed out of the system and down the drain. The unit then prepares itself for the next conditioning cycle.*
