WaterMax® Water Softener + Filter - CUSTOMIZATION

Water Softener Filter Diagram

The WaterMax® provides a unique water treatment solution because it is customizable, to address specific water problems.

Three separate compartments allow the WaterMax to be customized for your specific water treatment needs.

This flexibility means that instead of using multiple units to treat your water, you can meet all of your needs in one highly-efficient water treatment system.

Three Compartment Design

Untreated tap water problems typically include noticeable objections, such as bad taste, odor, and discoloration.

It is also common for tap water to seem fine when it actually contains problematic elements such as calcium, magnesium, chlorine, or lead.

Custom Media Solutions

Every WaterMax is built with Fine Mesh Resin and Bacteriastat, to protect the development of bacteria.

The three compartment designs allow for the use of additional custom media options to address specific treatment needs.

WaterMax® Water Softener + Filter - USE & CARE

To achieve the maximum benefit and performance from your WaterMax, here are a few important use and care items that you should be aware of:

  1. Salt level should always be at least ⅓ full. Refill the salt when the level drops below the water level in the brine cabinet. Clean white pellet, cube-style, or solar salt is recommended - do not use rock salt.
  2. Adjust clock during Daylight Savings, if you change time zones, or your electricity is shut off for any reason. Check your controller for the correct time and reset as necessary. See Customer Settings.
  3. Be sure to protect your appliance from freezing, including the drain line.
  4. Inspect and clean the brine tank and air check/draw tube assembly annually or when sediment is present in the brine tank.

For additional care details, please refer to the Owner’s Manual below. And if you have any further questions, please contact your local dealer.
