On at least an annual basis (more frequently in heavily polluted
environments) the sample tube that attaches to the inlet and to the Model
5030
i
Beta module should be removed and cleaned. The use of a bottle
brush and string will allow you to remove any deposits within the sample
tube. This same procedure also applies to the heater tube.
The “
Installation
” chapter covers detailed installation instructions. After
proper installation, it is recommended to check the weather-proof
installation at all interfaces exposed to ambient conditions. Ensure that the
condition of the roof flange and silicone caulking will prevent any
precipitation from entering the shelter and possibly damaging the
instrument’s electronics.
Use the following procedure to inspect and clean the fan filter (
Figure 5–
4
).
1.
Remove the fan guard from the fan and remove the filter.
2.
Flush the filter with warm water and let dry (a clean, oil-free purge will
help the drying process) or blow the filter clean with compressed air.
3.
Re-install the filter and fan guard.
