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.
