
CAUTION
Be sure to apply the pipe against the port on the indoor unit correctly. If the centering is improper, 
the flare nut cannot be tighten smoothly. If the flare nut is forced to turn, the threads will be
damaged.
Do not remove the flare nut from the indoor unit pipe until immediately before connecting the

connection pipe.
Hold the torque wrench at its grip, keeping it in the right angle with the pipe, in order to tighten the 
flare nut correctly.
Tighten the flare nuts with a torque wrench using the specified tightening method. Otherwise, 
the flare nuts could break after a prolonged period, causing refrigerant to leak and generate a
hazardous gas if the refrigerant comes into contact with a flame.

CAUTION
If it is placed horizontally, keep it within ± 15°. Otherwise, it will not separate the refrigerant evenly, 
causing a reduction in performance.
