1. A method of connecting a refrigerant pipe with an assembling jig of an air conditioner having an indoor unit and an outdoor unit, the method comprising: preparing the assembling jig and locating a grip-ring, a washer, at least one O-ring on an outside portion of the assembling jig, the grip-ring configured to prevent the refrigerant pipe from being separated, the washer configured to prevent the O-ring from being damaged, the at least one O-ring configured to prevent refrigerant from leaking;inserting the assembling jig into a refrigerant pipe connection part of the outdoor unit;coupling a coupling nut to an outer circumferential surface of the refrigerant pipe connection part in a loosely fastening state of the coupling nut;separating the assembling jig from the refrigerant pipe connection part via a hole formed through the coupling nut when the coupling nut is in the loosely fastened state;inserting the refrigerant pipe into the refrigerant pipe connection part by passing through through-holes, which are respectively formed in centers of the grip-ring, the washer, and the O-ring; andfastening the coupling nut to at least a predetermined torque such that the coupling nut presses the O-ring inward to the refrigerant pipe connection part. 2. A method of connecting a refrigerant pipe with an assembling jig of an air conditioner having an indoor unit and an outdoor unit, the method comprising: preparing an assembling jig, locating a grip-ring, a washer, at least one O-ring on an inside portion of the assembling jig and coupling a coupling nut on an outside portion of the assembling jig;inserting the refrigerant pipe into the assembling jig;separating the assembling jig from the coupling nut, wherein in a state that a grip-ring, a washer, at least one O-ring and the coupling nut is coupled to the outer circumference surface of the refrigerant pipe, the grip-ring configured to prevent the refrigerant pipe from being separated, the washer configured to prevent the at least one O-ring from being damaged, the at least one O-ring configured to prevent refrigerant from leaking, and the coupling nut configured to couple the refrigerant pipe;inserting the refrigerant pipe, the grip-ring, the washer, and the O-ring into a refrigerant pipe connection part of the outdoor unit in a state that the grip-ring, the washer, the O-ring, and the coupling nut are coupled to the refrigerant pipe;fastening the coupling nut on the refrigerant pipe to an outer side of the refrigerant pipe connection part. 3. A method of connecting a refrigerant pipe with an assembling jig of an air conditioner having an indoor unit and an outdoor unit, the method comprising: preparing an assembling jig, locating a grip-ring, a washer, at least one o-ring on an inside portion of the assembling jig and coupling a coupling nut on an outside portion of the assembling jig;inserting the refrigerant pipe into the assembling jig;separating the assembling jig from the coupling nut, wherein in a state that a grip-ring, a washer, at least one o-ring and the coupling nut is coupled to the outer circumference surface of the refrigerant pipe, the grip-ring configured to prevent the refrigerant pipe from being separated, the washer configured to prevent the at least one o-ring from being damaged, the at least one O-ring configured to prevent refrigerant from leaking, and the coupling nut configured to couple the refrigerant pipe;inserting the refrigerant pipe, the grip-ring, the washer, and the O-ring into a refrigerant pipe connection part of the indoor unit in a state that the grip-ring, the washer, the O-ring, and the coupling nut are coupled to the refrigerant pipe; andfastening the coupling nut on the refrigerant pipe to an outer side of the refrigerant pipe connection part.
