the small pipe of the connecting pipe must be covered by thermal insulation materials, be
bundled by adhesive tape, and be isolated from air.
The joint connecting to the indoor unit must be wrapped by thermal insulation material.
There shall be no gap between the connecting pipe joint and the wall of the indoor unit. Refer
