It should be stated in the manual that an entire connection pile should be used.
It should be stated in the manual that it is recommended to place the joint of the connection pipes at the
outdoor side, if can’t be at the outdoor side, the side that cannot be reused (not detachable) must be installed
at the indoor side.
When the connection pipe is reused, the horn mouth needs to be reinstalled.

WARNING!
The area of the room in which R32 refrigerant air conditioner is installed cannot be less than the minimum
area specified in the table below, to avoid potential safety problems due to out-of-limit of refrigerant
concentration inside the room caused by leakage of refrigerant from refrigeration system of the indoor unit.
Once the horn mouth of connecting lines is fastened, it may not be used again (the air tightness may be
affected).
A whole connector wire shall be used for indoor/outdoor unit as required in the operation specification of
installation process and operation instructions.
