Cleaning Instructions; Fault Finding - 3M Speedglas Adflo Instrucciones De Uso

2. Fit the breathing tube to 3M Adflo Powered Air Respirator
and attach the airflow meter in the other end.
3. Switch on 3M Adflo Powered Air Respirator at the lower
airflow setting.
4. Cover the air outlet of the airflow meter with your hand
until an audible warning is heard and the red indicator
illuminates
5. Remove your hand. The alarm should now stop.
6. Hold the flow meter tube vertical at eye level.
7. Wait until the position of the ball becomes stable (1-6
min) and then check that the bottom of the ball is above,
or at the same level as the marking on the flow meter
tube. If the ball does not reach the level, check chapter

Fault Finding

OPERATING INSTRUCTIONS
Switch on 3M Adflo Powered Air Respirator by pressing
the ON button once (nominal airflow), twice (airflow plus).
Pressing the ON button a third time will make 3M Adflo
Powered Air Respirator return to nominal airflow.
One green indicator = nominal airflow
(see technical specification)
Two green indicators = airflow plus
(see technical specification)
To switch 3M Adflo Powered Air Respirator off, press the
OFF button for at least 1 second.
If the red light illuminates together with an audible
warning, this indicates that the airflow is too low (less
than manufacturer's minimum design flow rate). If the low
flow alarm is active for more than two minutes, 3M Adflo
Powered Air Respirator will automatically turn off.
3M Adflo Powered Air Respirator has a three bar battery
indicator (see fig E:1) showing remaining capacity. When
the last bar starts flashing and an audible warning is heard,
less than 5% battery capacity is remaining. The warning
sound will change noticeable after a while and 3M Adflo
Powered Air Respirator will turn off automatically. See Fault
finding chapter for details.

CLEANING INSTRUCTIONS

Clean the equipment with a mild detergent and water. If you
suspect that the inside of the breathing tube is dirty, it must
be changed.
To avoid damage to the equipment do not use solvents
for cleaning. Do not immerse in water or spray directly
with liquids.
The Particle and Gas filters cannot be cleaned. Do not
attempt to remove contamination using for example
compressed air as this will damage the filters, the equipment
will not give the expected protection and the warranty will be
invalidated.
The 3M™ Adflo™ Spark Arrestor/Pre filter protects and/
or increases the lifetime of the 3M Adflo Particle filter and
should be used at all times.
If not a clean spark arrestor is used there is an increased
risk of fire in the particle filter.
MAINTENANCE
Battery charging
The charger is intended for indoor use only. Both the
standard and heavy duty battery will be fully charged in
about 4 hours depending on residual capacity.
The battery can be charged when installed in 3M Adflo
Powered Air Respirator, or separately (see fig D:1) 3M Adflo
Powered Air Respirator must not be used while charging.
The battery charger is designed for fast charging of 3M
Adflo batteries with capacity 2,5 to 4,5 Ah.
2
The charger controls the charging automatically, after
fully charged, trickle charging will keep the battery at full
capacity.
= Charging (steady charge indicator light)
= Trickle charging (slow blinking indicator light)
= Temperature too high/low (fast blinking
indicator light)
Recommended temperature during charging is between 0
to +40°C.
The battery will discharge after a long period in storage.
For this reason, always re-charge the battery if it has been
stored for more than 15 days. To achieve maximum power
when the battery is new, or has been stored for more than
three months, charge and discharge the battery at least
twice. Ensure that the mains supply voltage to the charger
is correct (see charger). After charging is completed,
disconnect the battery charger from the mains supply and
then the 3M Adflo battery.
If the charger indicator light will not light up when connecting
the charger to the battery, please check cords and
connectors.
Replace the battery and gently pull the battery pack to
confirm it is locked in place (see fig G:1).
Change of filters/spark arrestor (see fig H:1)
The particle filter must be changed if the battery operating
time becomes too short or 3M Adflo Powered Air Respirator
does not give enough airflow. The graph (see fig I:1) shows
the relation between runtime in hours and the particle
filter clogging. When the red indicator is illuminated, you
can expect a short battery runtime and a particle filter
replacement is recommended. Note! The start point
(indicator reading) is different when a gas-filter is added
Worn out components should be disposed of according
to local regulations
FAULT FINDING
Should a fault occur which causes a stop, reduction or a
sudden increase in airflow within the headtop, leave the
contaminated workplace at once and check the following:
Fault-Finding Guide:
Fault Probable Cause

short tones blocked
Red indicator 2. Filter clogged

3. Filter Cover

If the air density decreases (eg. at high altitudes), 3M Adflo
Powered Air Respirator has to use more power to generate
a sufficient air flow which influences the filter indicator
reading.
