[. . . ] (Professional installation is required to capture and recharge the refrigerant. ) Now - The new self-sealing Quick-Connect coupling uses synthetic seals and metal threads, so the couplings can be removed and reconnected as often as needed with no loss of refrigerant. (Professional installation is not required when all couplings in the system are Quick-Connect. ) Self-sealing Quick-Connect Adapter Kits (P/N 755570000) are available for replacement cooling units or evaporators that join older "one-shot" units to their new self-sealing counterparts. [. . . ] (Professional installation is required to capture and recharge the refrigerant. ) New Quick-Connect Adapter Kit (P/N: 755570000) HOW THE QUICK-CONNECT COUPLERS WORK When disconnected, spring-loaded valve assemblies in the male and female coupling halves are sealed to prevent refrigerant loss and the inclusion of air or foreign materials. A spring in the male coupling half presses the bonded poppet against sealing surface "A" of the coupling body. Likewise, a spring in the female coupling half presses the sleeve against sealing surface "B" of the stem valve head. When partially connected, the sealing surface of the male coupling body contacts the bonded seal of the female coupling's sleeve assembly as the two coupling halves are threaded together. At the same time, the stem valve head in the female coupling assembly contacts the male coupling's bonded poppet, forcing air out of the coupling. During this stage, both coupling halves are still completely sealed, preventing leakage of refrigerant. Thread coupling halves together by hand to ensure proper mating of threads. Just hold it with your 7/8" wrench. Using the 7/8" wrench on the male coupling body hex (holding the male coupling hex stationary) and the 15/16" wrench on the female coupling nut, tighten (clockwise) the female coupling nut until the coupling halves "bottom out " or a definite resistance is felt. This will require about 6 full turns. IMPORTANT: Do not rotate the S2 male or S5 female coupling bodies during connection. Only rotate the coupling nut on the S5 female coupler. D 7. Using a marker or ink pen, mark a line lengthwise from the coupling hex to the bulkhead. then tighten an additional 1/8 to 1/4 turn. [. . . ] then tighten an additional 1/8 to 1/4 turn. The misalignment of the line will show the degree of tightening. [. . . ]
