I bought this R/O system for a water treatment for an ice machine at a church. It arrived in a timely manner but the instructions are very vague on hooking it up. Especially to the electricity. It says it is 220 but just has a two prong plug for 110. I researched and researched till I was crazy. Finally I called customer support ( which by the way there is no number for in the manuals) I found it on the filters.
They finally told me it was a regular 110 plug. I don’t know why they tell you it is 220 because it is not.
After getting it hooked up and turned on it worked and I left it over night. The next morning I checked it and it would not let water through the solenoid. I called customer support and they sent me a new solenoid. It took about a week to get it. I finally replaced it and still no water. I called customer back and talked to a fella there that told me he would have the original guy “Nick” call me back. It didn’t happen until I wrote a review that made them look bad. Nick called me and said the guy never told him I had called. He is now working at trying to get replacement parts to me. I am trusting that it will be resolved. Thanks to Nick we are working towards success
I also ordered the water monitor to know how the treated water was and the fittings are wrong to hook it up. The fittings are for the wrong size lines.
Over all I believe the system is going to do the job.
