Context
Convert the 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 60 meters. If L exceeds 60 meters, contact Huawei technical
support.
