Cleaning and Routine Care

Periodically clean the Orion G Multigas and Leak Detector case
with a soft damp cloth.

Checking The Probe Inlet Filter

Orion G Multigas and Leak Detectors contain a filtering system to
protect the pump from particles and water in the sample air. If
the filter becomes clogged, the sample flow may be blocked, or
and extra load may be placed on the pump; therefore, check the
filter regularly.
The frequency of checks should depend on amount of pump
usage and concentration of particles allowed to enter the pump.
In dirty applications, replace the dust filter every 200 hours.

Replacing the Filters

When replacing external dust and water filters, prevent any
dust or dirt around the filter housing from entering the pump
housing. Dust or dirt in the pump unit may impede pump
operation.

Probe Dust Filters (see FIGURE 8-2 and TABLE 8-3)

1. Unscrew the leak sensor housing.
2. Remove the two filters from the housing cap.
3. Install the new filter in the housing cap recess.
4. Re-install the filter housing.
Internal "Firewall" Filter (see FIGURES 8-1 and 8-2 and
TABLE 8-2)
The pumped version of the Orion G Multigas and Leak Detector
contains an internal "firewall" filter. This filter forms a final barrier
against any dust that enters the pump assembly when external
filters are replaced. The "firewall" filter is provided as a final
safety precaution and should rarely, if ever, require replacement.
