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

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!

..try not using it....Richard Gray was detrimental to my system....all systems are different.

OMG!  All I can say is that it DID save my system.  Also I'd heard that the unit was supposed to be bulletproof.  Conversly, there is no longer any customer support.  Sigh, just blew $800.
