Connecting the Refrigerant Tubing Use of the Flaring Method Many conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units.

  • Page 98: Connecting Tubing Between Indoor And Outdoor Units

    07-115 SSHP_II 5/7/07 4:00 PM Page 98 Caution Before Connecting Tubes Tightly (1) Apply a sealing cap or water-proof tape to prevent dust or water from entering the tubes before they are used. (2) Be sure to apply refrigerant lubricant to the matching surfaces of the flare and union before connecting them together.

  • Page 99: Insulating The Refrigerant Tubing

    07-115 SSHP_II 5/7/07 4:00 PM Page 99 Do not use a spanner to tighten the valve stem caps. Doing so may damage the valves. Depending on the installation conditions, applying excessive torque may cause the nuts to crack. Precautions for Packed Valve Operation If the packed valve is left for a long time with the valve stem cap removed, refrigerant will leak from the valve.

    07-115 SSHP_II 5/7/07 4:00 PM Page 100 9-4. Taping the Tubes (1) At this time, the refrigerant tubes (and electrical wiring if local codes permit) should be taped together with armoring tape in 1 bundle. To prevent condensation from overflowing the drain pan, keep the drain hose separate from the refrigerant tubing.
