► Remove the valve from the pipeline and bring it into horizontal position.
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.
WARNING!
Leaking gasket!
Danger of injury due to escaping medium because of damage, aged or incorrectly lubricated gaskets.
► Store gaskets if possible in a cool (room temperature), dry and dark place.
► Before installing them, the gaskets have to be checked on possible aging damages, such as fissures and hardenings.
► Regular inspection of damage and replace gaskets as needed.
► Lubricate the gaskets with silicone or Polyol based grease. Do not use mineral oil-based greases or Vaseline (Petrolatum).
► Observe the special manufacturers notes for paint-compatible valves (LABS cleaned).
CAUTION!
Do not make any changes to the product!
Material damage and/or risk of injury due to modifications to the product or incompatible spare parts.
► Secure the system/device against unintentional operation.
► Do not use defective spare parts.
CAUTION!
Incorrect spare parts!
When replacing, only original Georg Fischer Piping Systems spare parts intended for the valve type may be used.

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.
