Sampling systems should be designed to comply with the Searchpoint Optima Plus operating conditions,
for example, sample temperature, cleanliness, water content, dust content etc.
The RGC has inlet and outlet gassing pipes with outer diameter 6 mm. The cell is not directional so either
pipe can be used as the inlet.
Note: The Searchpoint Optima Plus will often be supplied with a Flow Housing fitted. Ensure that the correct
gassing pipes are used. The gassing pipes for the RGC are the ones which support the retaining nuts for
the Weather Protection or the Flow Housing.
In addition, consider the following points: -
1. Maximum flow rate should be 0.3 litres per minute.
2. A flow failure indicator should be included in the system.
3. If possible, use negative pressure to avoid the risk of pressurisation affecting the gas reading.
4. The choice of sampling lines should be appropriate to the application.

The duct mounting kit is assembled and installed onto a duct as follows:-
1. Cut a square 230mm by 230mm hole in the duct wall. Drill the holes required to attach the mounting
plate to the duct wall.
2. Place the Searchpoint Optima Plus unit on the side of the mounting plate where the threaded bushes
protrude and feed the wires through the central hole.
3. Locate the unit's boss in the central hole and feed the unit's wires through the chosen cable entry on
the junction box.
4. Screw the unit into the junction box until the assembly is secure with the mounting plate trapped
between the box and the Searchpoint Optima Plus.
5. Add the appropriate support bracket and bolt to the junction box.
6. Blank off any unused support bushes.
7. Remove the covers from the ends of the gassing cell inlet tubes.
8. Attach the gassing tubing to the ends of the gassing cell inlet tubes.
9. Fasten the mounting plate to the wall of the duct, ensuring that the seal is compressed.
10. Fit approved cable glands to the junction box cable entries as required to maintain the certification
and IP rating.
11. Fit approved blanking plugs to unused junction box cable entries as required to maintain the
certification and IP rating.
12. Fit the external field wiring through the cable glands and secure.
13. Terminate the gas detector and field wiring in accordance with Chapter 4 (Electrical Installation)
