Outdoor Unit Tubing
1.
Connect a wide tube (3/4") to the wide tube
valve.(Fig. 3-77)
2.
Connect the tube assy, which was packed in the
indoor unit carton, to the narrow tube valve.
3.
Before attaching the tube assy to the mounting
valve, wrap the supplied packing A (3/4"
×
1-3/8"
×
T3/16") onto the 5/16" tube of the tube assy to
avoid direct contact of the tube assy with the
mounting valve. (Fig. 3-78, 3-79)
4.
Similarly arrange the supplied packing B (2-3/8"
×
1-3/16"
×
T3/16") on the mounting valve. (Fig.
3-78, 3-79)
5.
Insert clamp Ain the extracted round hole (3/16")
on the mounting valve, and bind the tube assy
and packing A. (Fig. 3-78)
6.
Insert clamp B in the square hole of the mounting
valve, and bind it so the tube assy is in contact
with packing B. (Fig. 3-79)
7.
Connect the narrow tube (3/8") between the
units. When tightening the flare nut, use the
double-wrench method. (Torque: 300 to 340
lbs.·in) (Fig. 3-80)

After completing the tubing work, check that the
tube assy is not in direct contact with the 3/4"
tube.
