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

My unit was hit with a major power surge induced by lightning storm.  I need to learn how to reset the circuit breaker and I need to buy a new battery pack for it.  The company got bought out so they are giving nonexistant customer support while milking the sales.  Any advice here regarding availability of battery packs?  Any advice regarding location of circuit breaker so I can reset it?  Feeddback greatly appreciated!
