ENGLISH
Refrigerant piping installation
Connection of Outside units
When installing the branch pipe vertically between the outside units, the refrigerant can be un-
even between the outside units, leading to compressor burn and reduced capacity
* Install the branch pipe between outside units so that the outlet pipe is parallel to the surface.
