On at least an annual basis (more frequently in heavily polluted

environments) the sample tube that attaches to the inlet and to the Model

5030i 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.
