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
Subsection 9.1 “Standard Specifications.”
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 installa-
tion.
• Never loosen the four bolts securing the cover
flanges (Refer to figure 3.1.) If the seal liquid
leaks, the transmitter cannot be used.
4.2 Mounting
The transmitter is mounted on a process using its high-
pressure side flange as shown in Figure 4.1. The
mating flange, gasket, stud bolts and nuts are to be
procured by the customer.

IMPORTANT
Please use a gasket with an inside diameter (ød)
that is greater than the diameter of the dia-
phragm seal. If a gasket with a smaller inside
diameter is used, the diaphragm may not func-
tion correctly. (Refer to Subsection 9.4 ‘Dimen-
sions’)
4.3 Rotating Transmitter Section
The transmitter section can be rotated in either direc-
tion to any desired position. Note that there is a stopper
which prevents the transmitter from being rotated more
than 360
°
.
1) Using the Allen wrench, remove the two setscrews
securing the transmitter section to the capsule
assembly.
2) Rotate the transmitter section slowly to the desired
position.
3) Tighten the two setscrews to a torque of 1.5 N·m
{15 kgf·cm}.
IMPORTANT
Do not rotate the transmitter section more than
the above limit.
