4.1 General information
The following points must be observed during installation:
•
If a support is required for mounting devices greater than DN 400, then follow the instructions on
storage! (

see chapter 3.3.1 "Nominal widths greater than DN 400", page 32)
• The flow direction must match the identification marking if available.
• The maximum torque must be maintained for all flange screws. (

see chapter 4.2 "Tightening
torques", page 35)
• Install the devices without any mechanical tension (torsion, bending).
• Fit flange devices with plane-parallel counter-flanges only using the appropriate seals.
• Use a seal made of material compatible with the measurement medium and the measurement me-
dium temperature.
• Seals may not extend into the flow area, since any turbulence affects the device accuracy.
• Pipelines must not exert impermissible forces and torque on the device.
• Only remove the sealing plugs in the cable fittings when installing the electrical cables.
• Make sure that the case lid seals are positioned correctly. Carefully close the lid. Tighten the lid
screws hand-tight so that the O-ring is sealed.
• Install the transmitter with a remote mount design at a location that is largely free of vibration. (  see
chapter 13.2.7 "Pipe vibration according to EN 60068-2-6", page 185)
• Do not expose the transmitter and sensor to direct sunlight; provide sun protection if necessary.
• Ensure sufficient cooling when mounting the transmitter in a control cabinet. Maximum ambient tem-
perature of the transmitter: 60 °C.
• In devices with a remote mount design and a measuring accuracy of 0.2 % of the measured value,
the correct assignment of the sensor and transmitter must be ensured. Devices that belong together
are designated with the same last digits, e.g. X001 and Y001 or X002 and Y002, on the nameplate.
4.1.1 Selecting seals
The following notes must be observed when mounting the seals:
Devices with hard rubber, soft rubber or ceramic carbide lining
• Additional seals are always needed for devices with hard/soft rubber or ceramic carbide lining.
• The manufacturer recommends using seals made of rubber or rubber-like sealing materials.
• When selecting seals, make sure that the tightening torque listed in chapter 4.2 "Tightening torques",
page 35 is not exceeded.
Devices with PTFE, PFA or ETFE lining
• No additional seals are needed for devices with PTFE, PFA or ETFE lining.
Devices with a connection flange design
• Sensors with a connection flange design are installed without seals directly in the pipeline.
IMPORTANT (NOTE)!
There is the additional document "JUMO flowTRANS MAG S/H - Safety Manual Ex for devices 406012 -
406019" for the measuring systems that are used in potentially explosive areas.
The information and data contained in the document must also be strictly observed.
