When we moved into our house 5 years ago, the previous owners had installed a LG Split System Air-Conditioner (LST243H-2) but had failed to leave the users manual behind. Through trial and error we eventually discovered the important features (a.k.a how to turn the damned thing on) but there was a whole bunch of modes for which we simply couldn’t fathom. The remote control had very little text, and more hieroglyphics than an Egyptian Tomb. It never occurred to me before to Google the model number until today.
Sure enough, I found a PDF version of the users manual for a LG LST243H-2. Woot!
