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 10.1 “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 installation.
4.2 Mounting
᭿ The impulse piping connection port of the transmit-
ter is covered with a plastic cap to protect against
dust. This cap must be removed before connecting
the piping. (Be careful not to damage the threads
when removing these caps. Never insert a screw
driver or other tool between the cap and the port
threads 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 4.2.1.
᭿ The user should prepare the mating gasket for the
transmitters with Process connection code 8 and 9.
See Figure 4.2.2.
