A 7,400 BTU Emerson Quiet Kool window air conditioner I picked up for @TheAirConditionerGuy. I suspect this is a later model as it utilizes a Matsushita rotary compressor. It does have the Watt Watcher branding and features constant run and automatic fan settings.
Model number 7JJ7E-A
7,400 BTU cooling capacity
R-22 Refrigerant (unknown amount)
7.5 Amps
840 Watts
8.8 EER
The previous owner of the machine who sold it to me spoke very highly of it. I'm not sure what the history behind this unit is but he definitely wasn't the original owner -- the machine is older than him. There is very little rust and dirt accumulated on the condenser, and only a season or two of heavy use accumulated on the filter. This would lead me to believe it's a relatively low hours unit, but it does seem like this has been in a window for many years as the EKQ tag has faded signifiantly.
The machine performed very well during the test, providing upwards of a 30 degree temperature delta once the head pressure came up. It ran very quiet.
