SEER ratings are very misleading as they do not reflect actual operating conditions. Good old EER or actual amp ratings are desireable. I found another candidate. I haven't found a price yet but it looks quite interesting, it is the Fujitsu 12RLQ. This is another 240 volt unit but it's rated curent while delivering 12,000BTU is 4.5amp at an EER of 13.5 or 889 watts and it's maximum curent (while delivering 14,500BTU) is 7 amps. I'd use a 1 kva+ 120 volt isolation transformer to supply the other half of the 120/240. Fujitsu has another interesting candidate in the 12RQ it is 120 volt but doesn't have the 'overload' capability to do 14500 BTU, it's 12,000 BTU, draws 9.9 amps and 1070 watts.RegardsJerry 4107 1120
That'd work Richard. Put another way, if you hook the primary and secondary of an isolation transformer in series and observe the proper phase polarity (ie you hook the secondary up the right way) you can consider the thing a center-tapped autotransformer that will boost 120 to 240 if the 120 is hooked from one end to the center (the primary in this case) and the load is hooked across the whole thing. If you get the secondary hooked up incorrectly, it'll result in turning 120 into amost zero volts...I've got 1 or 2 spare 120-240 step up transformers -big- that are probably good for 2-to 2-1/2 KW continuous... if anyone wants one email me. They're heavy, about 40-50 pounds but they're very robust and would easily run a roof air. I use one to operate my miller 250 off my 120 volt onan. I'm not offering them for sale- free if someone actually needs one, just pay the shipping.Hey- how do I get the "newbie" thing changed? I aint no newbie.......
