NO TICE
Before starting the compressor after power-on, ensure that the electric heating
belt of the crankcase has been heated for more than 12 hours.
●
If the one-way indoor unit pipe is longer than 30 meters and shorter than or
equal to 80 meters, you need to add refrigerant during commissioning.
●
Before charging refrigerant, ensure that air is exhausted from the gas pipe
connecting to the refrigerant cylinder.
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 80 metes. If L
exceeds 80 meters, contact Huawei technical support.
