Usage
6. Usage
Switch on the unit by pressing the ON/OFF button on the control panel.
The airflow can be adjusted by two arrow-buttons from 180 I/min up to
220 I/min.
The unit ensures a constant supply of air. The microprocessor inside the
unit automatically regulates the motor speed to compensate the filter
clogging and the battery state. If the microprocessor cannot keep the ad-
justed airflow, the unit will sound a ‚beeping' alarm (an acoustic signal can
be heard). At which point the user must check the blower unit. If possible,
the microprocessor automatically reduces the airflow to the next lower
level, if it fails to meet the lower level, the alarm will still sound. When the
airflow falls below the minimum safe operating level, a second audible
alarm joins the first and the unit will vibrate. At this point, the user must
stop working at once, leave the working environment and reach an area
nominated to be safe and change the filter or recharge/change the battery.
To check the battery:
When first starting the unit, the battery LED must show red - this shows a
fully charged battery. It is recommended that only a fully charged battery
should be used when starting a work shift.
With a fully charged battery in place, the unit should function normally,
but if the audible alarm still sounds, the user must change the filter. If the
problem still persists, see chapter 8 for additional suggestions.
