INSTALLATION
3.1 Unpacking and Visual checking
Take all normal precautions when opening the packages. In particular, avoid the use of long
bladed cutters. Check that all pipe connections have compression nuts and olives intact.
Search packing if any are missing. Check for any sign of damage. Carefully remove any internal
packing material.
THE SENSOR UNIT IN PARTICULAR SHOULD BE HANDLED WITH GREAT CARE SINCE
THE MEASURING SENSOR IS MADE FROM FRAGILE CERAMIC MATERIAL.
3.2 Siting
3.2.1 Electronics
A site should be chosen that is not subjected to ambient temperature greater than 50°C.
Care should be taken to mount the unit where it is not likely to receive heavy knocks or jolts.
Diagram 1 below gives details of mounting dimensions. The enclosure should be mounted
vertically, taking the standard precautions when installing equipment of this size and weight.

Mounting dimension details
3.2.2 Catalytic Reactor and Sensor unit
Chose a site where the ambient temperature will not exceed 70°C. To enable the flowmeter to
operate correctly the unit must be mounted vertically ±2°.
Refer to the drawing on the following page for installation and dimensional details and observe
the followings points.
WARNING
Parts of the assembly behind the heat shield run at elevated temperatures. Care
must be taken to ensure that they cannot be easily touched in normal operation.
CAUTION
All wiring from the catalytic reactor and the sensor unit must routed so as to avoid touching
any of the sensor unit’s surfaces.
WARNING
Under normal conditions the gases emerging from the sample outlet are
asphyxiating, and under fuel-rich conditions could contain poisonous carbon
monoxide. These gases will also be hot, normally in excess of 100°C, and
any extension tubing must be able to withstand this temperature and be of a
diameter and length that will not to cause a significant back pressure.
