WEC400

The WEC system utilizes positive and negative electrodes with an electrical charge, known as electro-membrane technology, to greatly reduce total dissolved solids (TDS) hardness, and other contaminants at the water point-of-entry in the home. The dual-module system is designed for sequential production and regeneration. When the ion removal capacity is attained, polarization occurs, releasing collected ions into the wastewater. Simultaneously, the second module initiates service, while the first module enters regeneration mode.

No Salt.

It uses an electro membrane technology.

The WEC removes contaminants from water by using polarity and reverse polarity to attract and release ions. This process is supported by the internal pump, which flushes the captured contaminants through the drain system.

The WEC will automatically bypass and the home will still receive feedwater.

During these states feedwater will be supplied instead of product water:

Regeneration Line CIP state, CIP state, CIP Flushing state, Error state, Module Protection state, and Offline mode.

Several errors will result in WEC being bypassed and the home receiving feedwater until the error is addressed. Some errors will still allow WEC to produce product water until the errors are addressed.

Yes. The WEC works with most tankless water heaters as well as combi-boilers and tank-style water heaters.

The recommended service flow rate is 5.3 GPM for max efficiency, but can work up to 10 GPM.

Aside from price and weight, WEC600 is for water under 500 ppm total dissolved solids (TDS), and WEC400 is for water under 300 ppm TDS.

No, but WEC will come with NaviLink Lite.

NaviLink Lite enables real-time monitoring of product information through your smart device (phone or tablet). This includes daily water usage and the quality of incoming/outgoing water based on TDS.

WEC should not be exposed to extreme temperatures, both hot and cold. WEC will not perform as expected under freezing conditions and water may freeze within the lines and the unit. The ambient operational temperature minimum is 40 degrees Fahrenheit.

Little maintenance is required with WEC. The Clean-in-Place (CIP) feature provides automatic self-cleaning that can be pre-programmed to a desired time to remove the contaminants that build up in the NDI module membranes.

Occasionally filling the CIP solution reservoir and replacing the pre-sediment filter and post carbon block filters.

Depending on typical usage and water quality, based on a family of four, maintenance should occur every 50,000 gallons or every six (6) months.

Navien recommends having a professional servicer to perform the maintenance service

Occasionally adding the 50% citric acid solution to the CIP reservoir inside the unit may be performed by the homeowner, however, Navien always recommends maintenance to be performed by a professional service company.

The Navien CIP Solution.

Indoors on a flat level surface at the municipal water point of entry.

2.5’ x 2.5’

Yes, WEC installation must be performed by a qualified installer.

The power supply required is AC 120 Volts / 60 Hertz.

WEC must only be installed indoors unexposed to the elements and on a flat surface.

Installation in the attic is possible, but the attic must be designed to support a minimum of 1000 lbs ((unit weight + two service personnel) x 2 times engineering factor) under any circumstances. It should also be sufficiently spacious for easy access during servicing and must include a drain.

WEC-treated water can connect to all household appliances through the waterline.

Depending on your feedwater test you may need other water treatment systems to accompany the WEC. Please consult with you installing professional.

WEC will reduce spots from forming on water touching surfaces such as glass and stainless steel.

WEC will not make the water itself feel noticeably different, but it may make your skin feel slightly silky.

WEC protects pipes and appliances from scale buildup and corrosion, and aids in preventing rust and spotting.

Yes.

The WEC reduces harmful contaminants while softening* the water hardness, providing safer drinking water for the whole family. Also, skin care and hair regimens may be enhanced with WEC and may improve cosmetic effectiveness.

*This product reduces the concentration of hardness minerals but does not necessarily produce soft water, defined as having <1 gpg hardness.

WEC is generally quiet but may produce some noise during flushing or regeneration, staying below 50 decibels. It's quieter than a dishwasher, even during regeneration.

Hard water has negative impacts on your skin both in the short and long term, because harness minerals like iron, calcium, and magnesium can irritate and dry your skin and form free radicals that are known to breakdown collagen. Hard water will also make hair appear dull and can lead to an itchy scalp. WEC greatly reduces these hard water minerals without salt providing better water for improved appearance of hair, skin, and makeup application.
