5. Display and buzzer
The blower device contains a display which indicates the battery status
and the fan motor power. The device will provide full protection in the
range A9-A0 and P9-P0 as long as the alarm does not go off.
Symbol A (green) = battery status
o
The display shows A8-A9 when the battery is fully charged, and A0 when the battery is empty.
o
For low battery the device gives a warning sound and A0 will start blinking on the display. After the
warning the blower device will operate normally another 5–10 minutes, after which the air flow will
deminish under the minimum flow rate.
Symbol P (green) = power indicator
o
The power needed is very much dependent on the filters and facepiece used. A low P-range does
not itself indicate any defect on the blower.
o
When the display shows P9, the blower device will easily reach the minimum flow rate. When the
display shows P0, the blower device reaches the minimum flow rate only with full motor power. This
makes the battery run down rapidly.
o
If the blower device no longer reaches the minimum flow rate, the buzzer will sound and P0 will flash
on the display. Decreased P-status can be caused by clogged filters or for instance a throttled
breathing hose. Check the filters and free air flow to the facepiece.
6. Use
See Instructions for Use of the facepiece and filter to be used.
Always use 2 filters of the same type and class.
Screw the filters hand-tight. Do not use excessive force, it may damage the blower. 30.10.2012 GS
Check before use
intactness of facepiece and blower device
filters are intact and properly fastened to the blower device. Shake the filter to ensure that there are
no loose components/contents. The filter shall be replaced if it has been exposed to strong press or
impact. It may be damaged, also by a fall on a hard surface, also when attached to a blower device.
breathing hose is tightly fixed to the blower device and facepiece.
Check adequate air flow and state of the battery
Assemble all items ready for use (facepiece connected) but do not don the unit.
Start the blower by switching to position | so the buzzer will sound.
Battery status A8-A9 indicates a fully charged battery. Lower A-indication is safe to use but indicates
that the battery is not full. Full duration time will require a fully charged battery.
Don the blower device. Carry the device so that you can check the blower's display when working.
Donning instructions for the facepieces are given in the respective Instructions for Use.
