Mounting Procedure - Toshiba LF664 Instruction Manual

4.2 Mounting Procedure

Use an appropriate device to carry
and install the LF664.
If this product falls to the
ground, injury, of
malfunction of or damage
to the product, can be
DO
caused.
4.2.1 Piping Connections
The LF664 detector has flanges on both ends of detector main body. To mount the LF664,
refer to Figure 4.1 and follow the procedure below:
1. Place one of the flange packing next to the upstream (or downstream) pipe flange.
Align the holes of the packing with those of the flange so that the holes are not obstructed.
2. Insert the LF664 detector in pipeline in accordance with the flow direction arrow
on the detector.
IMPORTANT
A crane is needed to carry and install the detector.
3. Insert the bolts, one at a time, through the hole in the upstream pipe flange and
packing, and then through the hole of the detector flange. Then thread nuts, one at a time, on
each end of the bolts, finger-tighten. This will help support the detector on one side.
4. Insert the downstream (or upstream) packing between the detector flange and the
downstream pipe flange. Align the holes of the packing with those of the flanges so that the
holes are not obstructed.
5. Inert the bolts, one at a time, through the hole in the downstream pipe flange and
packing, and then through the hole of the detector flange. Then thread nuts, one at a time, on
each end of the bolts, finger-tighten. This will help support the detector.
6. While centering the detector with the longitudinal axis of the pipeline, tighten the
bolts with a wrench diagonally across in even increments. Bolt torque should be limited to
that shown in Table 4.1
IMPORTANT
When high-temperature fluid is being measured, radiant heat from the detector pipe
surface and adjoining pipes may cause the ambient temperature of the converter to go
above 60 °C. If the ambient temperature goes above 60° C, try to lower the
temperature by measures such as wrapping heat-insulating materials over the detector
pipe and adjoining pipes
CAUTION
Turn off mains power before
working on pipes.
