In order to prevent damage to the flare caused by over-tightening of the flare nuts, use the table above as a
guide when tightening.
When tightening the flare nut on the liquid tube, use an adjustable wrench with a nominal handle length of
200 mm.
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.
Therefore, do not leave the valve stem cap removed. (Fig. 1- 57)
Use a torque wrench to securely tighten the valve stem cap.

3. Insulating the Refrigerant Tubing
Tubing Insulation
Thermal insulation must be applied to all units tubing,
including distribution joint (purchased separately).
* For gas tubing, the insulation material must be heat
resistant to 120°C or above. For other tubing, it must
be heat resistant to 80°C or above.
Insulation material thickness must be 10 mm or greater.
If the conditions inside the ceiling exceed DB 30°C and
RH 70%, increase the thickness of the gas tubing
insulation material by 1 step.
Two tubes arranged together

If the exterior of the outdoor unit valves has been finished with a square duct covering,
make sure you allow sufficient space to access the valves and to allow the panels to be
attached and removed.

CAUTION
Taping the flare nuts
Wind the white insulation tape around the flare nuts at the
gas tube connections. Then cover up the tubing connections
with the flare insulator, and fill the gap at the union with the
supplied black insulation tape. Finally, fasten the insulator at
both ends with the supplied vinyl clamps. (Fig. 1- 59)
Fig. 1- 59
Insulation material
The material used for insulation must have good insulation
characteristics, be easy to use, be age resistant, and must
not easily absorb moisture.
After a tube has been insulated, never try to bend it into a narrow curve because it
can cause the tube to break or crack.
Never grasp the drain or refrigerant connecting outlets when moving the unit.
