Richard Gray Power Conditioner/UPS Maintenance. Model RGPC 400 Pro

Hello nouveau920-

I use RGPC 400 Pro conditioner for over 10 years now.
I have not read about a buy-out? Whom bought the company?

The same happened to Running Springs a few years ago.

I would have to google the website to tell you.Have you ever had to replace the battery for the UPS?  If so, where did you get it?  They die generally after 5 years. I also need to throw the circuit breaker. I need to know how, but the maufacturer won't tell me how.  

I wish I could tell you- nouveau920.

hopefully the other owners here will be able to chime in. In all of my years of ownership, I have never had any problem/issue w/ my conditioner.

My dealer/retailer is no longer in business, otherwise, I will contact those guys and post your query.  Very odd for RGPC to sell?

Another thought-
start calling other RGPC dealers/retailers or send an email asking the same query.  Someone w/ the answer will respond to you.  Keep me posted.

Cool.  Good suggestion.  Like you, all the authorized dealers in my area have gone out of business.  I'll call around the U.S. & will keep you posted.  Thanks!
