Caution. Ensure that the panel is operated at the correct gas pressure.
The panel is located in the hazardous area (zone 0,1 or 2) of the application plant in a sheltered interior environment. Avoid a
location which subjects the katharometer unit to direct sunlight. When two katharometer panels are used they should be
positioned so as to be at the same ambient temperature.
The katharometer unit is fixed to the panel which has fixing holes at each corner and should be mounted on a suitable vertical
surface close to the sample tapping point. The installation dimensions for the panel is shown in Fig. 4.2.
