INSTALLATION
6.5 FENCE NOZZLE CONNECTION - Installation with section valves - Fig. 3
The system allows two Seletron type valves to be connected to handle "Fence" type nozzles.
The valves must be connected by means of an adapter cable.
6.6 FENCE / BUFFER NOZZLE connection - Installation with Seletron system - Fig. 2
The system allows two supplementary Seletron type valves to be connected to handle "Fence" or “Buffer” type nozzles.
• FENCE NOZZLE:
The Seletron installed must be a single type, regardless of what is mounted on the rest of the boom.
• BUFFER NOZZLE:
The Seletron and the nozzles installed must be of the same type as those mounted on the rest of the boom;
in particular, the end nozzles must be installed in the same position as the other nozzles and use the same flowrates.
Connect the Seletron nozzle holders to the ends of the boom using the appropriate splitter cable (

Fig. 2), using the last connectors on the right
and left of the main harness.
