* Provided that the maximum permissible detrimental gas concentration for the gas filter is not exceeded.
For power-assisted filtering devices with gas filter, concentration must not exceed 0.05 vol.% in gas filter
class 1 and 0.1 vol.% in gas filter class 2 and 0.5 vol.% in gas filter class 3.
** Nominal Protection Factor - a number derived from the maximum percentage of total inward leakage
permitted in relevant European Standards for a given class of respiratory protective device. This may not
be the level of respiratory protection that can be realistically expected in the workplace by wearers. Many
countries apply Assigned Protection Factors (APFs) for example UK and Germany shown in the table.
Employers may apply a value lower than the NPF/APF if deemed applicable. Please refer to EN 529:2005
and National workplace protection guidance for application of these numbers in the workplace. Please
contact 3M for further information.
BATTERY
General
Charge the battery before use. The recharging time of an empty battery is about 7 hours. The temperature
of the battery to be recharged must be +10...+ 30 °C.
Recharging should always take place at a room temperature of about +20 °C, in a dry place shielded from
dust and direct sunlight.
Always use the Proflow's own recharging device (it is delivered with the blower unit). The recharger performs
a battery test at the start of each charging to detect defective batteries.
Optimum performance with new battery packs is achieved only after they have completed three charge
cycles. (full charge to complete discharge)
Note!
A new battery or a battery stored for a longer period or an over-discharged battery may not function stably,
which will terminate the recharging prematurely. Monitor the red signal light (=charging in operation) after
e.g. 30 or 60 minutes and initiate the recharging several times if needed.
In too cold/warm an environment the battery will not be charged.
Never recharge in a potentially explosive environment!
When not in use, prevent over-discharge of battery by keeping the blower device always on recharge.
Overcharging of battery is automatically prevented.
To maintain the capacity of the battery pack, a regular full discharge (until the battery alarm sounds) must
be performed.
