•
To prevent dust, moisture, or other foreign matter from infiltrating the tube, either pinch the end or cover it with
tape.
•
Do not allow anything other than the designated refrigerant to get mixed into the refrigerant circuit, such as air, etc.
•
If any refrigerant gas leaks while working on the unit, ventilate the room immediately..
•
Ensure outdoor unit is charged with refrigerant.
•
Use copper alloy seamless pipes.
•
Be sure to use both a spanner and torque wrench together, as shown in
the drawing, when connecting or disconnecting pipes to/from the unit.
(Refer to Fig. 12)
•
Refer to Table 1 for the dimensions of flare.
•
When connecting the flare nut, coat the flare section (both inside and
outside) with ester oil or ether oil, rotate three or four times first, then
screw in.
(Refer to Fig. 13)
CAUTION
•
Over-tightening may cause the flare nuts to crack or the refrigerant to
leak.
•
Use the flare nut included with the unit.
•
See the following table for tightening torque.
Table 1: Tightening Torque
Not recommended but in case of emergency
You must use a torque wrench but when not possible, use the following installation method:
After the work is finished, make sure to check that there is no gas leak.
When you continue tightening the flare nut with a spanner, there is a point where the tightening torque
suddenly increases. From that position, further tighten the flare nut at the angle in the following table:
