On at least an annual basis (more frequently in heavily polluted
environments) the sample tube that attaches to the inlet and to the
Model 5028 i 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.
Equipment Damage
Some internal components can be damaged by
small amounts of static electricity. A properly grounded antistatic wrist
strap must be worn while handling any internal component. For more
information about appropriate safety precautions, see the “ Servicing ”
chapter.
