8) Remove the airflow indicator from the end of the
breathing tube.
9) To check the low airflow/high particle load alarm,
you will simulate a low airflow condition as follows:
With the Adflo
®
unit turned on, tightly cover the end
of the breathing tube with the palm of your clean
hand; the motor will then automatically speed up,
attempting to compensate for the low airflow
condition. Continue to press your palm tightly
against the end of the breathing tube, making a tight
seal. When you have achieved a tight seal, the unit
will sound an audible alarm and the center, red LED
on the on/off switch will flash (see Figure 7).
Figure 7:
Low Airflow Warning LED.
10) Remove your hand from the end of the breathing
tube; the audible alarm and the flashing red LED
should both stop, while the motor returns to a
slower speed.
11) Reattach the airflow indicator and repeat steps
5 and 7 above to confirm the airflow rate.
12) If the unit does not operate as described in all of
the above procedures, perform the Fault Location
Procedures listed in Section 2.5.
13) To turn the unit off, press the off button for two
seconds.
14) After confirming adequate airflow, filter condition,
and alarm function, assemble breathing tube to the
airduct of the headpiece assembly (see Figure 8).
Make certain to twist the breathing tube end
connector until it locks into place in the “J”
channel of the headpiece’s airduct.
To ensure adequate protection, the
performance of this unit must be
monitored in a non-hazardous envi-
ronment. During user break periods,
confirm sufficient airflow: the air-
flow indicator float rests at the mini-
mum float level. Failure to confirm
sufficient airflow in a non-hazardous
environment could lead to contami-
nant exposure resulting in serious
bodily injury or loss of life.

Connecting the
Breathing Tube.
To avoid the disconnection of the
breathing tube, be certain to fully
insert and twist the breathing tube
end connectors until they lock into
place at the end of the “J” channels
found on both the headpiece’s
airduct and the Adflo
®
Turbo Unit.
