Remove the protection cap not until shortly before installation.
Ensure that the diaphragm of the process connection is not damaged during
installation.
EN
The sealing faces at the pressure transmitter and the measuring point always
have to be clean.
Only ever screw in, or unscrew, the instrument using the spanner flats. Never
use the case or the cooling element as a working surface.
The correct torque depends on the dimensions of the process connection and
the gasket used (form/material).
When screwing in, do not cross the threads.
For information on tapped holes and welding sockets, see Technical information
IN 00.14 at www.wika.com.
Attach the connector and screw it in hand-tight. The assembly of the angular
connector is described in chapter 6.2 "Electrical mounting".
Sealing
Correct sealing of the process
connections with parallel threads at
the sealing face
using suitable flat gaskets, sealing
rings or WIKA profile sealings. The
sealing of tapered threads (e.g.
NPT threads) is made by providing
the thread with additional sealing
material such as, for example, PTFE
tape (EN 837-2).
For further information on seals see WIKA data sheet AC 09.08 or under www.wika.com.
