6. Maintenance

6.1 Cleaning

The person who is responsible for cleaning and maintenance
must have suitable training and be well acquainted with work
of this type.
Sundström cleaning tissues SR 5226 are recommended
for daily care. If the equipment is more heavily fouled, use a
soft brush or sponge moistened with a solution of water and
dishwashing detergent or the like. Rinse the equipment and
leave it to dry. Do not soak respirator inlet coverings in cleaning
solutions or solvents.
Do not wipe the respiratory protection inlet coverings with
strong solvents such as MEK, acetone, or toluene as those
may damage or distort materials.

6.2 Storage

After cleaning, store the equipment in a dry and clean place
at room temperature. Store the helmet with the visor in the
fully raised or fully lowered position. Avoid exposing it to direct
sunlight. Storage temperature: from -4°F to 104°F (-20 °C to
+40 °C) at a relative humidity below 90 %.
6.3 Maintenance schedule
Do not use the SR 500 Powered Air-Purifying Respirator with
respiratory protection inlet covering if the respirator fails any
of the requirements of the user inspection and performance
checks. Do not use the respirator until all necessary repairs
have been made and the respirator passes the performance
check. The following schedule shows the recommended
minimum maintenance procedures required in order to ensure
that the equipment is always in functional condition.

6.4 Spare parts

Use only parts or accessories as described in these User
Instructions or on the NIOSH Approval Label for the SR 500
Powered Air-Purifying Respirator. Do not attempt to repair or
modify any component of the system except as described in
the User Instructions.

6.5 To change the exhalation membrane

The exhalation membrane is mounted on a pin on the inside of
the valve cover. The cover must be changed at the same time
as the membrane. Proceed as follows:
• Snap off the valve cover from the valve seat. SR 520/SR
530, Fig. 12. SR 580, Fig. 29.
• Slip off the membrane.
• Press the new membrane onto the pin. Carefully check that
the membrane is in contact with the valve seat all round.
• Press the valve cover into place. A clicking sound indicates
that it is in place.

6.6 To change the visor

SR 520 and SR 530 Hoods
The visors of the SR 520 and SR 530 hoods cannot be
changed.
SR 580 Helmet
No tools are required to replace the visor. Proceed as follows:
• Unhook the face seal from the harness. Fig. 21.
• Remove the lower visor frame. Fig. 30.
• Remove the visor.
• Fit the visor into the lower visor frame. Applying a little water
to the seal will make fitting easier. Fig.16.
• Fit the lower visor frame to the helmet by sliding it into
position. Adjust the visor so it is fastened into the upper visor
frame. A 'click' indicates that the frame is locked in position.
Fig. 17-20.
• Check that the visor has achieved a full seal around the entire
visor frame.
• Attach the hooks in the harness. Fig. 21.

6.7 To change the face seal on the SR 580

SR 580 Helmet and SR 580 Helmet/SR 584 Welding shield
Face seal SR 584, T06-8012, is preferable to be used with
SR 580 Helmet/SR 584 Welding shield for protection against
radiation and spatter during welding, flame-cutting, grinding and
similar work.
The face seal plastic frame has a groove in which a flange on
the lower visor frame fits. The frame locks into position using
two pins – one at either end, which fit into a hole in the visor.
The face seal covering has hooks at either end that attach to
the head harness. Proceed as follows:
• Unhook the face seal from the head harness. Fig. 21.
• Remove the lower visor frame. Fig. 30.
• Unfasten the face seal by pulling its frame until the pins
release from the holes in the visor. Fig. 15.
•
• Remove the face seal.
•
• Fit the face seal on the inner flange in the lower visor frame.
Fig. 13. Start at one side, push the pin upwards and control
•
that the lip is fastened in the lower visor frame. Fig. 14.
• Push along the face seal frame so it is securely fastened on
•
the lower visor frame. Fig. 15. Control that the pin and lip is
fastened on both sides. Fig. 14.
•
• Fit the lower visor frame to the helmet by sliding it into
position. Adjust the visor so it is fastened into the upper visor
•
frame. A 'click' indicates that the frame is locked in position.
Fig. 17-20.
• Attach the hooks in the head harness. Fig. 21.
