Inspections
This equipment has been designed to fit in harsh environments requiring little or no
maintenance. Suggested inspection interval is six months, but extremely harsh
environments may require more frequent inspection and maintenance checks. On each
inspection, check the O-ring seals and the window wiper blade integrity. Replace them if
necessary.
Routine activities
Regularly perform the following routine activities:
Clean the glass
Use water or a liquid detergent that will not generate a hazardous situation.
Clean the germanium window
Remove the protective guard, unscrewing the three screws using a no-sparking hex
wrench. Use water or a liquid detergent that will not generate a hazardous situation.
Be careful not to scratch the carbon coating. Do not use ethyl alcohol, solvents,
hydrogenated hydrocarbons, strong acids or alkalis. These will irreparably damage
the germanium window. Once the cleaning is completed, properly reassemble the
protective guard.
Clean the unit
The layer of filth upon the unit should never exceed 5 mm thickness. Use a dry or
damp cloth. Do not use compressed air to clean the unit.
