Align flaring nut to the thread center, and screw the nut tightly by hand.
Screw tightly the flaring nut with torque spanner until the torque spanner produces "click” sound.
It is recommended to use torque spanner to connect the tubing. If other flexible or fixed spanner is used, it
may damage the horn mouth due to improper force.
The bending angle of the tube should not be too small or the tube may break up, so the service personnel
should use tube bender to bend the tube.
Never let water, dust or sand gets into the pipe.
