2.5 Installation of the Connection Pipe

(1) Align the center of the piping pipe with the relevant valve.

(2) Place the nut, spring washer, washer, O-ring cross the pipe sequentially, and keep them tightly close to

each other with a distance of 6-7mm from the O-ring to the pipe end.

(3) Screw in the pipe nut by hand and then tighten the nut with spanner.

(4) If supplied by the manufacturer, the connection pipe shall be installed in place so as to guarantee the

reliable connection.

Firstly connect the connection pipe to the FCU pipe, then to the connection pipe; pay attention

to the piping bending, do not damage the connection pipe; the joint nut couldn't tighten too much,

otherwise it may cause leakage.
