I’ve acquired a PPP, based on the original sign off sheet, its a model from 07. The unit appears to be working fine, with the exception of the following-voltage output reading is a constant 119 instead of 120. Is this a concern? Does the unit need to be sent back for recalibration?
Also, unit will randomly,have zero output at outlets. With the exception of a random dupluex, all others are dead. I must unplug the unit, which seems to reset it, unit then works fine.
Is there still a supply of parts for supporting this unit if a repair is needed? I’m hoping to keep it in my system indefinitely.
Great product! SN#PPP-BO-7FF091 Thanks!
