Cleaning, disinfecting and drying
Use only approved cleaning agents and disinfectants!
Cleaning: The full face mask must be cleaned after each use. Do not use
any organic solvents such as acetone, alcohol etc. Add some all-purpose
1)
cleaner such as Sekusept to lukewarm water then use the liquid and a
cloth to clean. Rinse thoroughly under running water.
Disinfecting: Disinfect the full face mask after each use. Immerse the mask
1)
in the disinfectant. Use Incidur disinfecting agent. Concentration: 2 %,
application time: 15 Min.
High doses and long exposure times can damage the full face mask! Rinse
thoroughly in running water.
Machine Cleaning and Disinfection: with Eltra
Drying: Shake water out of full face mask. Leave the mask to dry in a drying
cabinet or in air. Temperature maximal 60
light. Do not place the tensioners on the soft body. Grease the tensioner
guides with Vaseline.
Testing
The full face mask must be tested after each use and after each service
and repair.
1)
Test devices and accessories: Test-It 4100 (AG 02 400), Testor 2100
(R 53 400), Prestor (AG 02 000), Quaestor light (R 54 750), Quaestor
Automatic (AG 02 234) or Quaestor III (R 54 300), adapter (R 53 345),
sealing plug (T 52 246), exhalation valve plug (R 53 346) and mask
holder S (R 53 930).
Visual inspection of the speech diaphragm: Speech diaphragm and
O-ring must be clean and undamaged; clean or replace if necessary (also
see "Test and maintenance intervals").
Visual inspection of the inhalation valve: The inhalation valve inside the
mask connector is visible. Check whether the inhalation valve disks can
move freely by blowing in. Replace if clotted.
Visual inspection of exhalation valve: Remove the protective cap from the
facepiece connector and pull out the valve disc. The valve disk and seat
must be clean and undamaged. Clean or replace if necessary. Moisten the
valve disc with water and insert.
Carry out leak test: Observe the instructions for use of the test device.
Moisten the face seal with water, if necessary, then mount full face mask
with the mask holder S on the test head . Inflate the test head until the face
seal fits tightly in all places. Grease O-ring at sealing plug or adapter. Seal
the facepiece connector with the sealing plug or the adapter. If necessary,
moisten the exhalation valve. Produce a negative pressure of 10 mbar . The
full face mask is deemed to be tight if the pressure changes by no more
than 1 mbar after 1 minute, otherwise
Test with sealed exhalation valve: Remove the exhalation valve. Insert
exhalation valve plug and fasten with spring carrier. Produce a negative
pressure of 10 mbar . If the pressure change after 1 minute is less than 1
mbar, remove the exhalation valve plug, insert a new valve disk and repeat
the leak test. Otherwise
Underwater leak test: Immerse the test head with fitted full face mask in
water. Generate a positive pressure of approx. 10 mbar and rotate the test
head slowly underwater. Escaping air bubbles indicate the location of any
leak(s). Remove the test head and full face mask from the water and repair
the leak(s). Remove the exhalation valve plug and fit the exhalation valve.
Repeat the leak test.
Checking the exhalation valve opening pressure: When using the
Quaestor III test unit, the opening pressure must be at least 4,2 mbar with a
constant flow of 10 litres per minute through the full face mask. If not,
replace the spring and repeat the test.
When using a test unit that does not permit this constant flow rate, e.g.
Testor 2100, the opening pressure must be at least 4,5 mbar.
After the test: Remove the adapter. Remove the full face mask from test
head and dry if necessary. Replace exhalation valve cover so that it engages.
1) Follow the specific Instructions for Use.

Special maintenance work
Replacing the visor:
1 Hold the hexagon nut tight while unscrewing
the screws.
Remove tensioners. Prise the lens frame apart
with a screwdriver at the connecting points,
then pull it off to the top and bottom. Remove
support, see "Replacing the facepiece con-
nector". Detach the old visor from its rubber
frame. Insert a new visor, first in the upper half
and then in the lower half of the rubber frame.
The centre marks on the visor should be aligned with the seam on the mask
body. Draw the rubber frame over the edge of the visor on the right and left.
Moisten the outside of the rubber frame and the inside of the lens frame
with soap solution.
Fit first the upper, then the lower lens frame. Fit the support.
1 Screw tensioners and lens frames together by using screws and hexagon
nuts as well as one plastic washer each, tighten until the gap (x) between
the clamp lobes is between 3 and 0,5 mm.
2 Ensure correct assembly: The rotation axis must be below the frame
division.
Replacing the facepiece connector: Pull out the inner mask. Use a screw
driver to pry open the connector clamp. Remove the connector clamp as
well as sliding ring and support. Draw the facepiece connector out of the
mask body. Insert the speech diaphragm and exhalation and inhalation
valves into the new mask connector, and fit the connector so that the
centre-marks of the mask connector and mask body line up. Mount slide
ring and new connector clamp. Attach the hook to ensure the tightest
possible fit of the connector clamp. Push the support between connector
clamp and slide ring, then attach it to the lower lens frame and align.
Compress the nose on the connector clamp using pliers R 53 239 until the
facepiece connector is securely located in the mask. Press the inner mask
back into place.
Replacing the valve discs for control valves: Pull out the old valve discs
towards the inside. Insert the stems of the new valve discs from the inside
into the hole and pull towards the visor until the countersink of the stem is
visible. The valve discs must make even contact on the inside.
Replacing the speech diaphragm and
O-ring: Pull the inner mask out of the groove
of the screw ring. Unscrew the screw ring with
socket wrench R 26 817. Then turn the socket
wrench round and carefully insert it into the
holes of the protective screen, taking care not
to damage the diaphragm. Turn the speech
diaphragm to loosen it, and then remove it.
Remove the O-ring from the connection piece using the sealing ring lifter
R 21 519. Test the speech diaphragm and O-ring and replace if necessary.
Attach inner mask.
Replacing the exhalation valve disc: See "Visual inspection of the exhala-
tion valve". Replace exhalation valve cover so that it engages.
Replacing the inhalation valve disc or valve: Pull the valve out by the tab.
Remove the old disc and fasten the new disc. Press the inhalation valve
into the mask connector, so that it fits flush all round. The valve disc must
not be pinched. The disc must face inwards, and the stems face outwards.
Only use original Dräger parts. Always test for leaks after servicing
and/or replacing parts.
Storage
Wipe visor with an antistatic cloth. To prevent deformations that may lead to
leaks: do not lay the tensioners on the mask sealing frame. Pack the full face
mask in the specially provided bag or box. Store mask in a tension-free, dry
and dust-free place without deforming it in any way.
o
Storage temperature –15 C to 25
Keep away from direct heat and light. Observe ISO 2230 and national regu-
lations concerning storage, cleaning and maintenance of rubber products.
