5.1 Safety prescriptions for installation
Danger - Warning
The replacement operations must be carried out by a specialist authorized technician with specific
skills.
Provide appropriate safety measures and use suitable equipment to prevent risk of work accident to
persons involved in the operations and to those nearby.
Before starting installation, define a safety plan compliant to the legislation in force regarding workplace safety.
The specialist technician, authorized by the installer or owner, must asses whether the area has been prepared
correctly and whether the necessary installation equipment is available.
5.2 Mechanical and pneumatic connections
Pinch valve
The valve must be bolted on the two connecting flanges of the system; also, the pneumatic supply for the clo-
sure of the sleeve must be arranged.
Control Unit
Make sure to arrange the compressed air supply from the line and the connection of the control line to the
control unit.
Compressed air features
The compressed air used for the valve and control unit must be:
CLEAN: free from residues that might damage the sleeve or the solenoid valve fitted on the pneumatic actuator
DE-MOIST: the user should provide for a condensation separator.
OIL-FREE: The presence of oily substances contained in the air might cause the early and irreversible clog-
ging of the components.
Use only filters that maintain the air always clean and oil free.
The valve must be fed by a special independent branch that can be disconnected; pressure reducer valves
are installed at the connection points of the mains supply to keep the pressure level constant in the valve and
control unit.
