The gas side pipe, liquid side pipe must be faithfully heat insulated, if no heat insulation, it may cause water leakage.
The outdoor unit has been charged with refrigerant.

torque spanner together.
When connect cone nut, the inner side and outside of cone nut should paste with refrigerant oil. Use hand to twist 3-4
rings, then fasten with spanner.
