[RE-wrenches] AGM blew on discharge

[drake.chamberlin at redwoodalliance.org]

The owner said it blew out a lot of hot gas, but the lid did not blow 
off.

The system has a mini split on it that was on during summer nights, 
running off a bank of 8 L-16s. People think since mini splits are energy 
efficient, they are like LED lighting.
