Maintenance
W A R N I N G
Multiple hazards. Do not disassemble the instrument for maintenance.
If the internal components must be cleaned or repaired, contact the
manufacturer.
C A U T I O N
Multiple hazards. Only qualified personnel must conduct the tasks
described in this section of the document.
Clean the instrument exterior
The instrument exterior can be cleaned as needed. To avoid human
exposure to potentially dangerous chemicals, make sure to clean the
touchscreen immediately after contact with chemicals.
N O T I C E
To prevent damage, do not use an aerosol cleaner or glass cleaner on the
touchscreen. Do not leave visible moisture on the instrument or touchscreen.
Moisture can penetrate the touchscreen and damage the electronics inside.
1. Put the cap on the sample air intake nozzle to keep contamination
out.
2. Spray a mild cleaning solution on a soft cloth. Wipe the outside of the
instrument carefully.
3. Use a soft, dry cloth to wipe the touchscreen surface. If needed,
moisten the soft cloth with a mild cleaning solution.
Set the count to zero
Do this procedure after unexpectedly high particle counts. This
procedure will verify that the particle counter works correctly and will
remove residual particles.
1. Put the zero-count filter on the intake tube.
2. Turn on the unit and log in if needed.
