Q Water drips at the drain connection (service valve) of the outdoor unit.
A When a glass bottle is taken out of the refrigerator, moisture gets condensed on its surface
due to the temperature dierences. The same principle applies to the air conditioner. When
cold refrigerant goes through the copper tube, moisture gets condensed on the surface of the
