【About the torque wrench】
In order to prevent the leak of the refrigerant by the weak tightening of the flare nut or to
prevent the damage of the copper tube flare section by tightening too much, bind the flare nut
with a proper bolting torque. If a torque wrench is attached with a regular bolting torque, the
head will eventually break.
