For parallel threads, use at gaskets, lens-type sealing rings or WIKA prole
sealings at the sealing face . With tapered threads (e.g. NPT threads), sealing is
made in the threads , using a suitable sealing material (EN 837-2).
The torque depends on the sealing used. In order to orientate the measuring
instrument so that it can be read as well as possible, a connection with clamp
socket or union nut should be used. When a blow-out device is tted to an instru-
ment, it must be protected against being blocked by debris and dirt.
Installation
 Nominal position per EN 837-3 / 9.6.6 gure 7: 90° ( ⊥ )
 Process connection lower mount
 With lled versions the vent valve at the top of the case must be opened before
commissioning!
 For outdoor applications, the selected installation location has to be suitable
for the specied ingress protection, so that the instrument is not exposed to
impermissible weather conditions.
 In order to avoid any additional heating, the instruments must not be exposed
to direct solar irradiation while in operation!
 To ensure that the pressure can be safely vented in the case of failure, instru-
ments with blow-out device or blow-out back must keep a minimum distance of
20 mm from each object.
Permissible ambient and operating temperatures
When mounting the instrument it must be ensured that, taking into consideration
the inuence of convection and heat radiation, no deviation above or below the
permissible ambient and media temperatures can occur. The inuence of temper-
ature on the indication accuracy must be observed.
