PIPE CONNECTION

WARNING
Be sure to perform flare connection. It causes a malfunction and a fire of this unit when connecting 
the pipes other than flare connection (brazing etc.).
(1) Detach the caps and plugs from the pipes.
CAUTION
Be sure to apply the pipe against the port on the unit correctly. If the centering is improper, the flare 
nut cannot be tightened smoothly. If the flare nut is forced to turn, the threads will be damaged.
Do not remove the flare nut from the 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.
