Cold, Quiet, Efficient and Great price By golive888

Just like other reviewers, I'm very happy with this unit and the cost performance (including operating cost) is great! Here are few things to try to help people who are considering buying this great unit.

1. In order to install this unit properly, a vacuum pump, a vacuum gauge and a valve between the pump and the gauge, a hose to connect the vacuum pump and the service port on the low side (larger pipe side) are needed to get rid of air and more important moisture out of high and low side copper pipes and the evaporator inside of the indoor unit before opening the 2 valves at the outdoor unit. There is a way to install it without using a vacuum pump but small amount of refrigerant will be lost into atmosphere. (The refrigerant R410a is supposed to be ozone layer safe.)

2. The low side's service port's fitting size is 5/16, it is not 3/8 nor 1/4. Many AC gauge kit comes only with 1/4 fittings), when buying AC gauge kit, make sure it supports R410a (R410a pressure is much higher than R22, R134a) , a 5/16 female to 1/4 male adapter was needed for me to finish the installation.

3. All cables and copper pipes (3/8 OD and 1/4 OD) that come with the unit are only 13ft(4m) long. If the distance between the indoor unit and the outdoor are longer than 13ft, more cables and copper tubes will be required.

4. Follow the simple instruction in the small installation manual. FYI: This was my first air condition unit installation ever, All the info on the internet definitely helped, but it's not complicated but please make sure to really tighten the high side fitting very tight, the R410a pressure is very high, vacuum leak check was useful to check any leaks around the fittings, i.e. if vacuum doesn't hold after turning off the vacuum pump and close the vacuum pump side valve, there is a leak.

5. When operating at full power(the compressor on and indoor unit fan at high setting), Kill A Watt is showing less than 960W (110VAC input)! The air coming out of the indoor unit duct is very cold, and the fan in the indoor unit is very quiet even at high setting. Outdoor unit large cooling fan is also quiet.
Although I just finished installation, I recommend this unit to anyone, I only hope it'll last long.
I hope this info helps.
p.s. I am planning to power this efficient AC unit by using solar panels, LiFePO4 batteries and DC-AC inverter, no grid power. Zero electricity bill for air conditioning sounds kind of cool :)
