4. Installation
4.1 Precautions
Before installing the transmitter, read the cautionary
notes in Section 2.4, “Selecting the Installation
Location.” For additional information on the ambient
conditions allowed at the installation location, refer
to GS. (See Chapter 10.)
IMPORTANT
• When welding piping during construction,
take care not to allow welding currents to
flow through the transmitter.
• Do not step on this instrument after
installation.
• Rainwater and the like must be kept from
entering through the atmosphere release
hole and zero adjustment screw. Do not
install the transmitter with this hole facing
up. In addition, make sure that the pipe is
connected to the atmosphere release hole.
Using the transmitter without connecting
the pipe may affect the transmitter’s
performance.
• When installing a diaphragm seal, make sure
that no foreign matter has adhered to the
seal surface of the gasket or O-ring before
assembling. If foreign matter adheres, it may
lead to leaks.

4.2 Mounting
IMPORTANT
As the pressure-detector diaphragm is thin and
prone to damage, do not press on it or hit it
against something.
• In the case of screw mounting, remove the
dustproof plastic cap that is inserted in the
impulse line connection of the transmitter
before connecting the piping. When
removing the cap, make sure not to damage
the threads. Do not insert a screwdriver or
the like to remove the cap.
• The transmitter can be mounted on a
nominal 50 mm (2-inch) pipe using the
mounting bracket supplied, as shown in
Figure 4.2.
• If you specified A for the process connection
code, prepare the necessary gasket shown
in Figure 4.3.
• For models with flange mounted diaphragm
seals, mount the transmitter to the process
using flanges as shown in Figure 4.5. The
mating flange, gasket, stud bolts and nuts
are to be procured by the customer.
• For models with hygienic seals, mount the
transmitter to the process as shown in figure
4.6 and 4.7.
When mounting hygienic, extended type
seal, tank spud is required. For information
of a tank spud and other parts for mounting,
see 4.6.
