133 Technical Document Technical Data 1. Basic Connection Procedure Outer Pipe VU Socket Inner Pipe TS Socket Steps 1) Component preparation Prepare required socket for connecting double contained pipe and fitting. 2) Outer pipe connection �@ VU socket connection �@ Slide inner pipe (backward) and thrust the connecting outer pipe. �A Connect VU socket and outer pipe. 3) Inner pipe connection �@ TS socket connection �@ Slide pipe outer pipe (backward) and thrust the connecting inner pipe. �A Connect TS socket and inner pipe. 4) Inner pipe connection �A Inner-to-inner pipe (fitting) connection Slide outer pipe (backward) and connect inner pipe with socket connected and other inner pipe. 5) Outer pipe connection �A Outer-to-outer pipe (fitting) connection Connect outer pipe with socket connected and other outer pipe. If the pipe is going to be extended further, do not forget to place VU socket first before connection. Separate sockets (inner pipe TS socket, outer pipe VU socket) are required for connection.
