## Questions & Answers

**Q: I will be powering this ac unit with a generator. What are the exact power requirements? Wattage and or amps. Voltage is given 110ac.**
A: According to the description this unit uses 1500 watts. That's 14 amps at 110 AC. While it MAY be possible to run it on a 14 gauge wire, 15 Amp circuit, National Building Code in the United States will require it to be on a 12 gauge wire, 20 Amp circuit. They require that in order to prevent the wire from over heating and possibly starting a fire. BTW, it is recommended that you put it on its own circuit.

**Q: What is the warranty period?**
A: Hello and thank you for your question in regards to the COSTWAY mini spilt ac unit. The warranty is 8 years on parts replacement and 8 years on compressor.

**Q: Could the outside unit be used in a space for a wall through AC?  I understand it needs lots of air circulating.  Is it that unit loud?**
