5. Maintenance
The instrument requires routine maintenance according to the instruction below.
In addition an annual calibration is required; please return the instrument to the KANOMAX
service center or your distributor. This annual maintenance will ensure the instrument
stays in good condition and performs accurate measurements.
Danger
5.1 Alcohol Cartridge
The alcohol cartridge is equipped with an isopropyl alcohol reservoir. The felt inside the
cartridge absorbs and retains the alcohol. The alcohol cartridge is inserted in the main
unit; therefore it must be kept clean. If dust gets into the instrument, it may clog the
internal nozzle and affect the proper operation of the instrument. Be careful when storing
and handling the alcohol cartridge and storage cap to keep them free of contamination.
Cleaning and Replacing the Felt
The felt and mesh inside the alcohol cartridge can be replaced on site.
The instrument is provided with one (1) set of spare felt and mesh. In normal use, there
is no need to replace the felt unless the problems shown below occur:
1．The felt is contaminated with dust or oil.
→ This problem does not happen when the instrument is used in normal ambient air.
If the instrument is used for sampling highly-concentrated particles (sampling in a
boiler room or sampling combustion aerosols), the felt may become contaminated
and require replacement.
2．The mesh inside the alcohol cartridge is clogged.
→ If the alcohol cartridge has been soaked in contaminated alcohol for a long time,
the mesh inside the alcohol cartridge may be clogged. The mesh can be cleaned
by washing it, but if the clogging persists, it must be replaced.
3．The instrument is not able to measure due to humidity.
→ If humid air is drawn in the instrument, moisture may accumulate in the alcohol
cartridge. In this case, the felt must be removed and allowed to dry before being
returned to the cartridge. If the felt or mesh is obviously contaminated, it must be
replaced with the provided spare.
however, this will not cause a performance problem.
DO NOT OPEN the outer case of the instrument.
It is very dangerous to open the outer case of the instrument because a
Class 3B laser diode is contained in the instrument.
Opening the instrument case will void the warranty.
For annual maintenance, or for any service not described in this
operation manual, please contact the KANOMAX service center or
your distributor.
Over time the felt may become discolored,
