Abstract

An outdoor unit includes an indication cover including a cover portion on which at least one of a type of refrigerant employed and a caution are marked, the cover portion being disposed so as to cover a hexagonal column-shaped outer circumference of a sealing hexagon nut, a ring portion attached to a gas-side valve which is the refrigerant pipe connection valve, and a joint portion formed so as to be bendable and connecting between the cover portion and the ring portion.
