I should clarify my last post on this topic.
In my experience, when the H-Lo is connected to a standard 15 amp/120v shore power service, only the fan component of the A/C unit will run, but not the compressor. The A/C compressor requires a 20 amp service, at minimum, to get this running.
If the Hi-Lo 30 amp shore cable is plugged into an extension cord, assure it is a high gauge (12 gauge) extension cord.
