Installation process

► Always install the valve in the open position.
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.
CAUTION!
Thermal expansion forces on piping system!
Preventing thermal expansion during temperature changes results in axial or bending forces. Piping system and valve may be da-
maged.
► Make sure that the forces are absorbed by suitable fixed points before or after the valve.
CAUTION!
Pipe not in aligned!
Risk of injury and/or damage to property due to leakage of the piping system because of stress forces in the piping system.
► Make sure that the valve and pipe are aligned with each other.
4.2.1 Radially mountable and dismountable valve
All materials with type 604
1. Loosen the union nuts and slide them onto the intended pipe ends.
2. Depending on the type, cementing, screwing or fusing the connecting parts onto the pipe ends (specific projects are described
in Georg Fischer Planning Fundamentals Industry - Glued/Fused connections).
3. Place the diaphragm valve between the connection parts.
4. Tighten the union nuts manually.
WARNING!
Tighten union nuts up to DN50 only hand-tight!
Risk of injury and/or material damage due to leaking liquids caused by overtightened or defective union nuts.
► Tighten union nuts up to DN50 only hand-tight, without auxiliary tools.
