Removal and disassembly

DANGER!
Uncontrolled escape of the medium!
If the pressure in the piping system has not been completely relieved, the medium can escape in an uncontrolled manner. Depending
on the type of medium, risk of injury may exist.
► Completely relieve pressure in the pipe before opening.
► In case of harmful, inflammable, hot or explosive medium, completely empty and flush pipe. Possible residues must be taken
into account.
► Provide for safe collection of the medium by implementing appropriate measures (e.g. connection of a collection container).
► Drain the valve with the valve in the half-open position and collect the medium.
► Hazardous medium residues may remain in the valve despite drainage.
► Wear appropriate protective equipment.
DANGER!
Use of hazardous and non-approved medium!
Non-approved chemically aggressive or hot medium can attack materials, cause personal injury and endanger the environment.
Components not in contact with the medium can be attacked by leakage inside the valve.
► Observe the safety data sheets or the applicable safety regulations for the medium used.
► Check the compatibility of the valve materials with the medium.
► Do not use unapproved medium.
► Regularly check the valve for wear and, if necessary, perform service.
► Wear appropriate protective equipment.
► For hot medium: Work only on cooled down system.
► In case of uncertainty regarding approved medium, contact the Georg Fischer Piping Systems Sales Company.
