Hydrophobic Filter
It is very important to prevent the ingress of water and moisture into the Falco as this can cause damage to the
PID sensor and electronic circuits. Please ensure that before running Falco you have attached a hydrophobic
filter to the instrument. The Luer is factory fitted to the Falco. The hydrophobic filter is then attached to the
Luer, please ensure the hydrophobic filter is fitted to the Luer the correct way round (see image below). The
hydrophobic filter must always be fitted and will need to be replaced on a periodic basis.
Sampling Tube Length
The maximum recommended sample tube length is 20m (4x2mm tube).
Sample tubing should be made of stainless steel or fluorinated material e.g., PTFE, PVDF
. This prevents VOC’s
“Sticking” to the inside walls of the tubing and causing false readings.
Removal of the Control Module
The removal of the Control Module will only be necessary if the module is no longer required in its detecting
position or if there is a module malfunction. The FALCO has an externally located intrinsically safe sensor,
allowing for quick and easy servicing without the need for a hot work permit. Dual certification allows the
FALCO to be serviced and calibrated in a hazardous environment without having to remove the power.
To Remove the Control Module
CAUTION:
This area must be known to be free of flammable concentrations prior opening the enclosure
To remove the FALCO as a complete assembly:
1.
Switch off and isolate the power to the FALCO.
2.
Unscrew and remove the Front Cover.
3.
Unbolt the three retaining bolts on the Control Module.
4.
Disconnect the Control Module from the Ribbon Connector and remove it.
5.
