4-3. Connecting Tubing between Indoor and

Outdoor Units

Tightly connect the indoor side refrigerant tubing

extended from the wall with the outdoor side tubing.

(Fig. 33)

To fasten the flare nuts, apply specified torque as:

Table 6

4-4. Insulation of Refrigerant Tubing

(For C2432 and CL2432)

To prevent heat loss and wet floors due to dripping of
condensation, both tubes must be well insulated with
a proper insulation material. The thickness of the insu-
lation should be a minimum 5/16 inch. (Fig. 35)

4-5. Taping the Tubes

(1) At this time, the 2 refrigerant tubes (and electrical

wire if local codes permit) should be taped together

with armoring tape. The drain hose may also be

included and taped together as 1 bundle with the

tubing.

4. Similarly arrange the supplied packing B (2-3/8"

1-3/16"

T3/16") on the mounting valve. (Fig. 31b,

31c)

5. Insert clamp A in the extracted round hole (

3/16")

on the mounting valve, and bind the tube assy and

packing A. (Fig. 31b)

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. 31c)

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. 32)

8. After completing the tubing work, check that the tube

assy is not in direct contact with the 3/4" tube.

CAUTION

After a tube has been insulated,

never try to bend it into a nar-

row curve, as this may cause

the tube to break or crack.
