Factory-mounting of shut-off valves and valve manifolds see page 2/142.

Included in delivery of the device:

•Brief instructions (Leporello)

•CD-ROM with detailed documentation

•Sealing plug(s) or sealing screw(s) for the process flanges(s)

1)For oxygen application, add Order code E10.

2)Not suitable for connection of remote seal. Position of the top vent valve in the process flanges (see dimensional drawing).

3)Only together with max. spans 250, 1600, 5000 and 30000 mbar (100.4, 240.9, 2008 inH2O and 435 psi)

4)When the manufacture’s certificate M (calibration certificate) has to be ordered for transmitters with diaphragm seals, it is recommended only to order this certificate exclusively with the diaphragm seals. The measuring accuracy of the total combination is certified here.

5)Whe the acceptance test certificate 3.1 for transmitters with direct-con- nected diaphragm seals is ordered, this certificate must also be ordered with the corresponding seals.
