NOTICE
•
Before installing the joints, ensure that there is no dirt or burrs
adhering to the various seat faces (pipe joints, gasket, etc.)
• Because the pipes can move relatively freely during installation
and the seat faces are liable to tilt, first temporarily tighten the
pipes, then tighten them to the specified torque and ensure that
there is no leakage from them.
•
When tightening two pipes together, be very careful that they do
not rotate together.
• After installing the pipes, apply the correct pressure to each pipe
joint and ensure that there is no leakage.
• Ensure that the various tightening torques conform to the above
table.
*If a soft washer #4840 FR–N (al rubber and carbon press fit
part) is loosened or removed subsequent to being installed, be sure
and replace it with a new one.
There is no need to replace it, however, for normal retightening.
