2.3 Installing the DT450G
Securely fix the DT450G onto a socket or flange on the probe inlet. When fixing the DT450G onto
a socket, use the supplied two M8-size bolts. When fixing the DT450G onto a flange, use bolts
having a size that conforms to the flange specifications.
Be careful not to damage the O-ring when mounting the DT450G onto a socket.
CAUTION
If the gas to be measured is flowing constantly through a duct where the DT450G is mounted, air-
purge the monitor as instructed in subsection 4.2.2. If you leave the monitor exposed to the gas
for a prolonged period without air purging the monitor, the resistance of the insulated part of the
sensor probe will decrease. This may result in a failure of the monitor to start smoothly.
