Mounting is only permitted in the depressurised state. Reliably
depressurise the instrument using the available valves and protective
devices (e.g. shut-off valve, monoflange).
Nominal position per EN 837-3 / 9.6.6 figure 7: 90° ( ⊥ ). Tolerance: ±5°
With parallel male threads (e.g. G ½ B) WIKA sealings must be used
With tapered female threads (e.g. 9/16-18 UNF) the process connec-
tion seals metallically without additional sealing.
When screwing the instruments in, the force required for sealing must
not be applied through the case, but only through the spanner flats
provided for this purpose, and using a suitable tool.
The tightening torque is dependent on the selected process
connection.
