5. Remove the hose, pressure gauge, and vacuum pump.
6. Install the needle valve nut and rear cover nut of the indoor unit and outdoor unit.
7. Wrap the gas pipe stop valve, liquid pipe stop valve and the pipes connected to the stop valve
with thermal insulation foam.
1. Convert the length of components that cause partial resistance loss such as elbows into the
length equivalent to that of straight pipes, and add the equivalent length to the length of the
straight pipe between the indoor and outdoor units to obtain the total one-way pipe length
(L). L should be less than or equal to 80 meters. If L exceeds 80 meters, contact Huawei
technical support.
2. Charge extra refrigerant before power-on commissioning.
