WIRING INSTRUCTIONS

Installation, adjustment and maintenance of the valve must be carried out exclusively by skilled and authorized service

technicians

1. Before electric wiring, check that the main voltage matches with the power supply voltage stated on the product label.

2. Disconnect power before wiring.

3. By wiring connector, use terminals and cables as reported in the Instruction leaet in the package.

4. Connect the power supply to terminals 1 and 2 and the ground wire to terminal .

5. Using energy saving Green connector with 12 and 24 Vdc comply with polarity.

INSTALLATION AND OPERATING INSTRUCTIONS

1. Make sure that all operating data indicated on the safety shut-off valve label correspond to those of the system.

2. Before installing the safety shut-off valve, quit the gas supply and make sure that the pipeline is free from impurities. The pipeline
must be vibration-free.

3. The ow direction indicated by the arrow on the valve body must be respected, facing towards the user appliance. The safety valve
can be installed either horizontally or vertically, provided that the coil is not turned downwards.

4. When installing the safety shut-off valve in pipework do not use the coil as a lever, but use the correct wrench.

5. The sealing material must be applied to the external thread of the pipeline only and not to the internal thread of the safety shut­off valve.

ADJUSTMENT OF FLOW RATE - OPENING TIME AND RAPID STROKE

QUICK OPENING SLOW OPENING

1. Coil fastening nut

2. Flow rate adjustment

Unscrew the nut and spin the internal screw clockwise to reduce
and counter clockwise to increase the ow rate.

1. Flow rate adjustment. Loosen screw A and rotate cylinder
B to the desired position. Tighten screw A to x the position.

2. Opening time adjustment. Turn screw C clockwise to

reduce the opening time or turn counter clockwise to increa-

se values.

3. Rapid stroke adjustment.

All the reported data are subject to be changed without notice. from 180911
