Berner SCOTT Sari Instrucciones Para El Uso página 36

With a blower device
•
Check adequate air fl ow (see Instructions for Use of the blower unit).
4.1 Fitting of the fi lter
•
Sari + Pro2000: Remove eventual safety plugs from the fi lter. Screw the fi lter tightly in the
connector of the mask (=inh. valve body).
•
Sari + Pro2000 + blower device: Screw the fi lters to the blower device and fi x the breathing
hose to the connector of the mask.
4.2 When needed, connect the spectacles to the inner mask and adjust their position.
4.3 A sweat band is recommended to control excessive hair.
4.4 Loosen the head harness straps.
4.5 Locate the chin pocket of the mask properly on the chin and pull the head harness
over the head.
4.6 Check that the chin is in the chin pocket. Tighten the straps (in the order 1–2–3). Start
with neck straps, pull backwards (not outwards). Then adjust the temple straps and fi nally
the upper strap. The cradle lies centered on the back of the head.
Check that the face seal touches the skin all around, especially under the chin pocket. Try
moving the mask sideways to verify that there is no slippage.
4.7 Check tightness of the mask (two alternative methods)
•
Cover the exhalation opening of the mask with your hand. Exhale gently to create
overpressure. There must be no leakage between the face and the face seal.
•
Cover the fi lter opening with your hand. Inhale to make the mask press onto your face.
•
If you fail to get a tight fi t (=potential leakage), adjust the head harness and fi lter.
5. Maintenance and storage
5.1 Test for function and leak-tightness
If components have been replaced (visor, valve discs or speech diaphragm), a test for function and
leak-tightness must be carried out with an appropriate test device (e.g. Pro-Tester code 141080).
The test is also done in case of a mask stored unused for a longer period, and at least once a year.
Check also that the faceblank has maintained its shape, the head harness is reasonably elastic,
the visor and the face seal are undamaged, and that the valve discs and the speech diaphragm's
O-ring are good and well in position. Damage must be repaired.
5.2 Replacing the visor
The visor is available in polyamide, polycarbonate, chemical-resistant laminated glass
or polycarbonate with a chemical-resistant and scratch-proof coating. The material code
is found at the upper right-hand corner of the visor. Replace visor if damaged, dirty or
scratched.
Material code:
F polycarbonate (PC)
F hard coated polycarbonate (HC)
polyamide (PA)
triplex
