I need Help I have a Grunaire GMU183HX system . The name tag says it is 220 volt but it it trips one leg L2 when energized. It will operate with this leg tripped which means it is running off 120Volts hoe can this be happening if the system is designed for 220Volts. IT cools , reaches Temp. shuts down , starts back up when it calls for cooling, Changes speed works just like it is supposed to. Pulls between 8-9 amps on start-up backs off to 4-5 amps when running. Some one HELP !!!!
