Do not use equipment before reading these instructions and obtaining product training.
INSTRUCTIONS FOR USE AND MAINTENANCE
•
Compressed air supplied to the Airvisor 2 family of products must be breathable quality complying with
EN 12021. Honeywell recommends the use of Clearflow Filter Systems to assist compliance. Air quality
should be checked periodically using suitable test equipment. Comply with the following instructions
before entering work area.
•
Airvisor 2 DAC (double action couplings) models propose specific double action connectors for
compressed air supply, giving specific connection format and extra protection against unexpected
disconnections.
CHECKS BEFORE USE
Check operation of warning whistle to ensure that the correct volume of air is supplied to the respirator (see instructions below).
Inspect all equipment for damage, paying particular attention to the hose, visor feed tube and face skirt.
Do not use the respirator if the face skirt or diffuser on the air supply tube are damaged as this will affect protection.
Ensure visor covers offer good visibility.
DONNING OF EQUIPMENT
Secure waistbelt assembly around waist and adjust to fit comfortably. If required, don Fabric Hood (25) followed by visor assembly.
Keep visor (6, 7, 8) raised and adjust crown strap and headband to fit firmly.
Plug the end of the visor air supply tube (5) into miniature High Flow quick release socket (17).
Select a suitable length air hose (23) up to a maximum of 10 metres and connect High Flow QR socket on hose to air inlet (21) on
waistbelt assembly.
Connect other end to filtered air supply.
When using Airvisor 2 DAC models, use the green air supply hose. Use blue hoses for standard Airvisor 2
models.
Couple air powered tool (24) if required, to air outlet (22) on the waistbelt assembly.
Turn on air supply and adjust pressure to give between 4.5 bars (61 psi) and 7 bars (102 psi) at waistbelt assembly inlet (see Supply
Pressure Chart overleaf). Ensure there are no air leaks. If the warning whistle sounds increase the input pressure until it stops. In case
the whistle does not stop when increasing pressure, close off the air supply and start again after having adjusted the pressure.
Please note that Airvisor 2 and Airvisor 2 MV kits used in conjunction with an auxiliary air powered tool, or spraygun, require higher input
pressures (so an extra check must be made). If working in this way the tool must be operated before wearing the respirator - if the
warning whistle sounds under these conditions increase the input pressure until it stops. This ensures that there is sufficient air for both
the respirator visor and the auxiliary tool or spraygun.
Lower visor, making adjustments as necessary to crown strap and headband to ensure optimum fit of face skirt around the face. Check
for any obvious visible gaps between the skin and the face skirt. If gaps are detected readjust the device until they are closed. You are
now ready to enter the contaminated area. Please note: that if the warning whistle sounds during normal working conditions this
indicates that there is not enough air flowing to the respirator visor – leave the contaminated area immediately, then remove the visor -
increase the input pressure to a suitable level.
Replacement of Air Supply Tube and Diffuser Assembly (All models):
If the air supply tube (5) is worn or damaged it must be replaced to avoid leaks.
Detach the tube from its mounting points (fitted in to notch at rear of headpiece and mounted on two clear retaining pegs) and
withdraw the diffuser from its centrally mounted, curved holder after removing the cap.
Install the new assembly by carefully feeding the foam diffuser in to the curved holder and clipping the cap back in place.
Reattach the air supply tube to the visor/frame using the two retaining pegs, making sure to fit the tube in to the notch in the
headpiece.
Replacement of Disposable Visor Covers (All models):
Locate visor cover (9/10/11) over metal studs on either side of the visor.
Replacement of Visor (DAVK-000*E & DAWK-4001E models):
Unclip visor air supply tube (5) from browguard.
Holding browguard, press the top of the visor (6) firmly from the outside inwards using thumb and index finger.
Unhook visor key hole slots from blue browguard pegs located on either side.
If visor air supply tube is to be re-used, unclip tube from inside visor by carefully pulling out the two clear retaining pegs, otherwise
discard both visor and tube.
To reassemble, feed air tube QR connector upwards through hole in visor foam.
Fit visor air supply tube to visor with the two clear retaining pegs and the centrally mounted, curved holder.
Relocate blue browguard pegs into key hole slots at top of visor and pressing firmly, rotate towards browguard and clip in position.
