3M Speedglas Adflo Manual De Instrucciones página 6

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 Purifying 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 Purifying
Respiratorreturn 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 Purifying 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 Purifying Respirator will
automatically turn off.
3M Adflo Powered Air Purifying 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 8% battery
capacity is remaining. The warning sound will noticeably change
after a while and 3M Adflo Powered Air Purifying 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 product do not use solvents or alcohol
for cleaning or disinfection. 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 helps protect and/or
increase the lifetime of the 3M Adflo Particle filter and should be
used at all times.
If a clean spark arrestor is not used there is an increased risk of
fire in the particle filter.
MAINTENANCE
The particle filter must be changed if the battery operating time
becomes too short or 3M Adflo Powered Air Purifying 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.
Replacement of:
● Battery see fig G:1. Replace and gently pull to confirm it is locked
in place.
● Particle filter/Pre filter/spark arrestor see fig H:1
● Belt see fig B:1
The particle filter indicator reflects particle clogging only. The
service life of the optional organic vapour/acid gas cartridge, when
used, must be estimated independently in accordance with a change
out schedule. Failure to do so may result in sickness or death.
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:

If the air density decreases (eg. at high altitudes), 3M Adflo Powered
Air Purifying Respirator has to use more power to generate a
sufficient air flow which influences the filter indicator reading.
STORAGE AND TRANSPORTATION
When stored as stated in technical specification, the expected shelf
life of the product is five years. The original packaging is suitable
for transporting and storage. To protect the equipment from dust,
particles and other contamination, use 3M™ Adflo™ Storage Bag.

Weight, 3M Adflo Powered
Air Respirator
(incl. P-filter, excl battery) 705 g
Expected service life: 5 years depending on conditions of use
Operation duration and combinations of respirator
equipment:
Estimated system duration based on testing at nominal air pressure
with a new fully charged battery and a new, clean filter at 20°C.
Actual system duration may be extended or shortened depending
on system configuration.
Note! The minimum design duration time is 4 hours on all combina-
tions with particle filters only. When gas filters are added a heavy-duty
battery must be used to meet design duration time of 4 hours. Head-
top model and certain accessories may impact estimated duration
time. The table below is an example of estimated duration time for
3M Speedglas Welding Helmet G5-01.
