A gfi is a ground fault interrupt, a cutoff switch/circuit breaker built into a wall recepticle power plug.
A Swamp cooler is and evaportation cooler aka Legionaires disease breeder. These actually work quite well in dry desert climates. In semi humid areas they work not so well, and here in Lousyanna people would say WTF is that? It Boosts humidity??? Can I buy some pot from you?
Thank you for the clarification. We're certainly not looking for humidity boosters here in NWFL!
