Turbo. The audible alarm should activate and the bottom LED on the filter
icon will flash red.
Note: High environmental noise levels or use of hearing protection may
interfere with the user hearing the audible alarms. Users may need to check
for the visual alarms more frequently in these environments.
OPERATING INSTRUCTIONS
DONNING
1. Select an approved breathing tube (See reference leaflet for list of 3M
approved breathing tubes) and connect top end to headtop assembly.
Inspect the gasket located on the bayonet end of the breathing tube (i.e. the
end that connects to the Powered Air Turbo) for signs of wear or damage. If
the seal is worn or damaged, the breathing tube should be replaced.
2. Insert the bottom end of the breathing tube into the outlet of the Powered
Air Turbo and turn the end of the breathing tube to ensure it is fitted firmly.
3. Select an approved belt (see reference leaflet for list of 3M approved
belts). The Powered Air Turbo has four locking studs (see Fig 7) and the belt
has four corresponding holes (see Fig 8). Insert the four locking studs into
the holes on the belt (See Fig 9). Push down on the belt between the top and
bottom holes on each side (see Fig 10). Slide the belt up (See Fig 11) until
the belt snaps over the belt locking tabs on the bottom of the Powered Air
Turbo (see Fig 12). Adjust and buckle the waist belt with the Powered Air
Turbo fitted comfortably around your waist. (See note below for fitting
optional backpack). See separate braces user instructions if used.
4. Adjust the Headtop as outlined in the appropriate User Instruction.
5. Switch on the Powered Air Turbo by pressing the on button for 1 second.
The unit will perform a self-diagnostic. Flow level, filter loading and battery
charger indicators will flash and the auditory alarm will activate. Fit the
Headtop and ensure at least minimum airflow is achieved. (The audible
alarm will sound if below minimum airflow - please see fault finding).
Note: When fitting the Powered Turbo to the optional backpack, it is
recommended that it is attached in the orientation shown in Fig 13. The
backpack adaptor should be fitted in the correct orientation to ensure this is
possible. Attach the backpack adaptor to the backpack as shown in Fig 14
and check that it is firmly held in place by the attached fastening. Insert the
four locking studs on the back of the Powered Air Turbo into the holes on the
adaptor and ensure a secure fit.
IN USE
The Powered Air Turbo will always start at the standard flow setting when
switched on. Press and hold the fan button for 1 second to change the airflow
setting. Repeated pressing of this button will cycle through the flow settings. If
no buttons are pressed after 30 seconds of use, the display will enter a
sleep-mode. Press any button momentarily to exit this mode.
The display also has an indicator for tight-fitting mode. When a breathing tube
for a tight-fitting facepiece is attached to the Powered Air Turbo, the Turbo
changes to operate in a tight-fitting mode and the indicator is lit.
Note: To conserve battery power when in the medium or high airflow setting,
the Powered Air Turbo will automatically step down to the next lower airflow
setting when the filter loading reaches approximately 90% or the battery run
time remaining is less than 4 hours. This will be accompanied by a short beep.
The step-down feature can be over-ridden by the user by pressing the flow
control button to move the airflow back to the desired flow. The low battery
alarm and low flow alarm will always operate as described above, when either
alarm sounds, users must immediately exit the contaminated area.

^ The filter loading indicator is for particulates only. It does not provide any
information about gas and vapour service life. Leave the contaminated area
immediately if taste or smell contaminants.
Use in the 'power-off' state is not normal, little or no protection is
provided and a build up of carbon dioxide and depletion of oxygen
within the Headtop may occur, vacate the contaminated area
immediately.
Take care to prevent the breathing tube from becoming looped around
protruding objects If during use, the airflow into the Headtop stops and the
alarm sounds, vacate the contaminated area immediately and investigate the
cause (please see fault finding).
NOTE: The 'in-use' life of the product will vary with frequency and conditions
of use. In everyday use, the expected 'in-use' life is 3-5 years. Some extreme
conditions may result in deterioration over a shorter period. The product must
be stored and maintained as stated below.
Note: Do not expose battery pack to temperatures above 54°C. The
Powered Air Turbo battery alarm will activate if battery pack temperature
reaches 54°C while the Powered Air Turbo is in use. The Powered Air Turbo
will shut down if the battery pack temperature exceeds 60°C.
^ Do not use the batteries outside of the recommended temperature limits.
DOFFING
Do not remove the headtop or turn off the air supply until you have
vacated the contaminated area.
Note: Contaminant may be removed by following the appropriate steps in the
cleaning instructions prior to doffing or disassembly of the system.
1. Lift the Headtop off the head.
2. Switch off the Powered Air Turbo by pressing the power button for 2
seconds.
3. Unbuckle the waist belt. If required, remove the belt from the Powered Air
Turbo by lifting the lower, centre portion of the belt over the locking edges
and sliding the belt down (see Fig 15).
4. If required, the breathing tube can be removed. However, the Powered Air
Turbo should be turned upside down so that the outlet faces the ground (see
Fig 16) to help minimise the potential for contamination of the outlet.
