2.4 Calibration
An air flow check can be undertaken by dis
connecting the hose and fitting the flow
checker. The OptimAir 3000 should then be
activated. The unit will self calibrate, reduc
ing the airflow until the point at which it will
be maintained. The indicator on the flow
checker can be read to confirm flow is above
the appropriate mark.
In normal use, switch on the unit and allow
to self calibrate, then fit the respiratory inlet
covering to your head and ensure that you
are comfortable with the airflow. The audible
alarm will sound if it is below the minimum.
WARNINGS: Proceed to the work area
only if you are satisfied with the opera
tion of the device.
Do not remove the respiratory inlet cov
ering or turn off the unit until you have
left the work zone, then remove the res
piratory inlet covering prior to switching
off the unit and unbuckling the waist belt.
With the IP54 rating of the device it is
permissible to wear the device during
specified decontamination shower pro
cedures.
3. Cleaning, Storage and Maintenance
Instructions
Do not clean in a work zone and use only a
mild solution of warm water and liquid soap
to wipe down the device with a clean cloth.
Never use other cleaning agents or solvents
of any kind.
Disinfection can be carried out using MSA
wipes (P/N 10000442).
There are no user serviceable parts and the
device must be maintained, serviced and
repaired only by properly trained personnel.
Replace the battery pack after ca.1000
cycles. The device should be stored in the
packaging supplied as indicated by the
markings on the packaging. The life of the
product will vary with frequency and condi
tion of use but provided no extreme condi
tions are encountered and the device is
stored as detailed, it is recommended that
the device is discarded after approximately 5
years service.

4. Selection and Use of Filters

Respiratory protective filters for use with the
OptimAir 3000 device are classified accord
ing to EN 12941 and EN 12942, and marked
with the filter type and standard(s) refer
ence. According to the filter type, filters have
the following main applications:
A: Vapours from organic compounds with a
boiling point higher than 65°C.
B: Inorganic gases and vapours, e.g.
Chlorine, Hydrogen Sulphide, Hydrogen
Cyanide (not Carbon monoxide)
E: Sulphur Dioxide, Hydrogen Chloride
K: Ammonia and organic ammonia derivtives
P: Particles of poisoning compounds with a
negligible vapour pressure
For these filters the class to be used depends
on the possible maximum concentration of
the hazard and required service time. The
class of the complete device (see classifica
tion table) according to EN 12941/ EN 12941
in conjunction with the appropriate threshold
limit valves and protection factors according
to local regulations can be used to determine
maximum permitted challenge levels.
