XERO Pure - Filtration

The XERO Pure employs a comprehensive three-stage purification process. First, water flows through a chloramine filter, effectively eliminating large particles. Next, it passes through an RO membrane, which significantly reduces contaminants. This membrane uses VFT (Variable Flow Technology) so it has optimal performance even at varying PSI. Lastly, the water enters a DI housing for final purification, ensuring a TDS below 10 ppm.

One of the great features of this system is the non-proprietary filter changes, allowing you to use any replacement that fits the system bought at your favorite supplier.

XERO Pure - Maintenance

Filters and When to change them

Replace the Chloramine Filter after 5,000 gallons or every two months.
DI Resin should be replaced as needed. If your TDS meter is reading over 010 ppm, then its time to change out your resin.
This system uses a refillable DI cartridge that holds just under 1/8 of a cubic foot of resin. When replacing your resin, pack the cartridge tight to the top making sure the arrow is up. Then lubricate the o-ring.
Replace the RO Membrane when the TDS of the purified water is only 80% of the incoming TDS. This means that the RO membrane is not performing at peak performance.

Tips

When closing the filters and housings with the included wrenches, do not over tighten.
When possible, transport your system lying down.
Never restrict or stop the flow of water from the waste water fitting at the bottom of the RO membrane.
Use XERO RO Guardian to prevent bacterial growth on your RO membrane during long periods of inactivity or while in winter storage.
Test the TDS of the supply water and pure water at each job.

Awesome Xero Pure!

This R/O DI System works great. Once I connect the tap water to the system within seconds the water is coming out 0 PPM. My tap water is 540 PPM so that’s just amazing how this system works. I wash solar panels and leaves them spotless.

Best System - Beginner or expert

I originally got a zero pro plus and it was unneeded. It was great, but a XERO pure is the best being for your buck never leave spots is lightweight and really gets the job done well.

Xero Pure water for simplicity

I've had the unit for a few weeks and must say it's a great investment. Easy to setup and use and a big time saver over using a ladder. Factor in the safety benefits and you have yourself a great option to save you all the way around. Time will tell how long the unit holds up as it's far too early to say. A couple of things I'd change: 1) Make the wheel base adjustable. It's so narrow that you must two hand it when moving or it will fall over. I undewit makes it easier to transport in a vehicle by being narrow. This makes it hard to move it one handed and use your other hand to carry a hose reel or pole. Collapsible handle and axle would remedy this issue. 2) Add a better female coupling for the inlet water hose, one that has wings. The current hex head is challenging when new to screw on and off and will most likely become more difficult with time. Adding an injection molded or 3D printed wing to the existing hex coupling would make is so much easier to use for very little additional costs. 3) Ensure the 2 ear clamps noted in the setup video is included in the kit. I received 1 ear clamps and they work fin for barbed fittings, they do not work for the pull on/off valve for through the pole water line routing. While a minor issue, it did result in my wasted time and additional need to source a small worm gear clamp locally. This made the complete kit a little less than complete. I really like the unit and the entire kit and hope to get many years of service from it.

Hi there, this would depend on the volume of resin, there is a chart in the description of the resin on our website that shows how much pure water can be created according to the incoming TDS: https://xeroproducts.com/products/xero-virgin-resin?variant=41017803210886

Question asked: I live in the northwest. What temp is it to where I would have to stop using my machine for solar panel cleaning?

29-10-2024

Hi there, great question! We suggest stopping at 35 degrees, that way no windows in the shade possibly freeze over and risk breaking/cracking a window.
