^ WARNING
Proper selection, training, use and appropriate maintenance are
essential in order for the product to help protect the wearer from
certain airborne contaminants. Failure to follow all instructions on the
use of these respiratory protection products and/or failure to properly
wear the complete product during all periods of exposure may
adversely affect the wearer's health, lead to severe or life threatening
illness or permanent disability.
For suitability and proper use follow local regulations, refer to all information
supplied or contact a safety professional or 3M on 0870 60 800 60 (UK) or

indicated.

SYSTEM DESCRIPTION

The 3M™ Versaflo™ TR-802E Powered Air Turbo is designed to be used in
conjunction with one of the approved headtops (see Reference Leaflet). This
product meets the requirements of EN12941 (Respiratory protective devices
– Powered filtering devices). The Powered Air Turbo is intended to be used
with a battery pack (TR-830) and a range of combined particulate/gas and
vapour filters, or particulate filters (one with additional nuisance odour
performance). The Powered Air Turbo can be manually set to provide three
levels of airflow (standard, medium and high). It also incorporates an
electronic control unit which provides an audible and visual warning of low
battery and/or low airflow into the headtop. The turbo has a filter indicator to
provide information on particulate filter loading and a battery status indicator
to provide battery charge information. When fully assembled, the TR-802E
may also be used in potentially explosive atmospheres. See Equipment
Marking and Technical Specification sections for further information on ATEX
Classification.
^ The filter loading indicator is for particulates only. It does not provide any
information about gas and vapour service life.

^ WARNINGS AND LIMITATIONS

Use this respirator system strictly in accordance with all instructions:
• contained in this booklet
• accompanying other components of the system (e.g. TR-802E Powered Air
Turbo Reference Leaflet, Filter User Instructions and Headtop User
Instructions).
Do not use in concentrations of contaminant above those specified in the
Headtop User Instructions.
Do not use for respiratory protection against unknown atmospheric
contaminants or when concentrations of contaminants are unknown or
immediately dangerous to life or health (IDLH).
Do not use in atmospheres containing less than 19.5% oxygen. (3M
definition. Individual countries may apply their own limits on oxygen
deficiency. Seek advice if in doubt).
Only use with Headtops and Spares/Accessories listed in the reference
leaflet and within the usage conditions given in the Technical Specification.
Only for use by trained, competent personnel.
Leave the contaminated area immediately if:
a) Any part of the system becomes damaged.
b) Airflow into the headtop decreases or stops.
c) Low airflow or low battery alarms activate.
d) Breathing becomes difficult.
e) Dizziness or other distress occurs.
f) You smell or taste contaminants or irritation occurs.
Never modify or alter this product. Replace parts only with original 3M spare
parts.
Do not use the TR-802E Powered Air Turbo in potentially explosive
environments not covered by the ATEX Classification reference in this User
Instruction. Doing so may result in serious injury or death.
For use in environments subject to high magnetic fields contact 3M
Technical Service.
Spark arrestor should be used in all situations where the Powered Air Turbo
may be exposed to sparks, molten metal or other hot particulates.
Materials which may come into contact with the wearer's skin are not known
to cause allergic reactions to the majority of individuals.
This product contains no components made from natural rubber latex.

PREPARATION FOR USE

Respirator systems are intended to help reduce exposures to certain
contaminants and should always be handled with care and fully inspected
prior to use. Check apparatus is complete, undamaged and correctly
assembled. Any damaged or defective parts must be replaced with original
3M spare parts before use. Undertake pre-use checks on headtop assembly
as outlined in the appropriate user instruction.
Battery
Inspect the TR-830 battery casing, hinge, latch and electrical contact pins
and replace battery if damaged. The battery should be charged immediately
after receipt as indicated on the product packaging (see Fig 1).
^ The TR-830 battery pack is only intrinsically safe when connected to the
TR-802E Powered Air Turbo. To reduce the risk of ignition of a flammable or
explosive atmosphere, batteries must be changed only in a location known to
be non-hazardous. Never bring this battery alone into an area which is
potentially flammable or explosive. Doing so may result in serious injury or
death.
^ The battery chargers for this system are not intrinsically safe. The TR-830
battery pack must not be charged in an area which is potentially flammable
or explosive. Doing so may result in serious injury or death. For battery
charging instructions, please refer to User Instructions provided with battery
charging kit. The battery charge can be determined by pressing on the
indicator as shown in Fig 2. (1 bar = less than 20%, 5 bars = 80 to 100%). An
identical battery indicator is also on the Powered Air Turbo display. Hook the
hinge end of the battery into its holder on the bottom of the unit. Push the
fastener side of the battery into the Powered Air Turbo and fasten with a 3/32
inch hex head tool. Use a hand tool only – do not overtighten. Pull the battery
gently to confirm it is locked in place.
Filters
Select an approved filter. (Please see TR-802E Powered Air Turbo
Reference Leaflet for list of 3M approved filters). The inner circular seal is the
primary seal between the filter and Powered Air Turbo. The outer barrier
prevents ingress of dirt and debris.
^ Inspect filter and inner seal before first installation or reinstallation and
immediately replace if damaged. Closely inspect filter plastic housing
including the corners and latches. Immediately replace if damaged. If the
filter has been mishandled or dropped, re-inspect fully. If you have any
concern, contact 3M Technical Service for guidance.
^ Always properly install the filter into the Powered Air Turbo.
Ensure the Powered Air Turbo is switched off. To install the filter, place the
left side of the filter into the Powered Air Turbo hinge and snap the right hand
side into place (see Fig 3). Gently pull the filter to ensure proper attachment
on both sides. Alternatively, a filter cover can be attached to the filter. Filters
and filter covers are marked with symbols for easy identification and
compatibility. See Reference Leaflet for details. Use of the filter cover is
optional but recommended. However, the filter cover must be used if using a
spark arrestor and/or pre-filter. Replace the filter cover if damaged. The filter
cover should be attached before installing the filter onto the Powered Air
Turbo. Insert the filter into the cover, ensuring the bottom latch tab snaps into
place and the filter label is visible in the filter window. Then install onto the
Powered Air Turbo as shown in Fig 3. If using the optional spark arrestor
and/or prefilter, place these into the filter cover in the order shown in Fig 4A
(where 1= Filter cover; 2= Spark arrestor; 3= Prefilter; and 4= Filter). Ensure
that the cut-outs of the spark arrestor and prefilter are aligned properly before
attaching the filter. See Fig 4B and 4C for correct positioning of the spark
arrestor and prefilter respectively. Spark arrestor should be used in all
situations where the Powered Air Turbo may be exposed to sparks, molten
metal or other hot particulates.
Airflow Check
The Powered Air Turbo is pre-calibrated to ensure the required airflow is
provided. It also compensates for changes in air density, which is affected by
elevation (height above sea level) and air temperature. Before use,
undertake air flow check using the air flow indicator tube as shown in Fig 5.
Allow the Powered Air Turbo to run for 1 minute before inserting the airflow
check tube into the outlet. Wait for an additional minute to allow the airflow to
stabilise. With the airflow check tube in the vertical position, ensure that the
bottom of the floating ball rests at, or above, the minimum flow mark for the
'letter' representing your 'zone' (see Fig 5). To determine your zone, you
need to know the elevation and temperature for the environment where you
are conducting the airflow check. Find the zone where your elevation and
temperature intersect on the chart shown in Fig 6.
Alarm Check
The audible and visual alarm will activate should the airflow reach the
manufacturer's minimum design flow (MMDF). To check for the correct
functioning of the alarms, place a hand over the outlet of the Powered Air
