Putting The Equipment On; Selection Of Protective Element - Sundstrom SR 200 A irline Instrucciones De Uso

• The membrane in the air distributor need not be
replaced.
• Check that the seal at the bottom of the filter con-
nection is in good condition.
• Check the condition of the head harness. The head
harness is a consumable item and should be
replaced if there are any signs of wear or reduced
elasticity.
• Check that the air flow - measured through the
mask - is at least 5.3 CFM (150 l/min).
2.3.1 Checking the air flow
• Connect the breathing hose of the mask to the
regulator. Fig. 4.
• Connect the compressed air supply tube to the
regulator. Fig. 5.
• Turn the regulator knob anti-clockwise as far as
it will go, in order to throttle the air flow rate to a
minimum. Fig. 4.
• Place the mask in the bag and grip the opening of
the bag so that it seals around the breathing hose.
Fig. 1:8.
• Grip the flow meter with the other hand and hold it
so that it points vertically up from the bag.
• Read the position of the ball in the tube. It should
float level with or just above the marking on the tube.
If the flow rate is below the minimum value, check that
• The flow meter is vertical.
• The float can move freely.
• The air supply is not restricted by kinks or other
restrictions in the hoses.
N.B. If the flow rate is below the minimum value,
the equipment must not be used. Get in touch
with the supplier or the manufacturer.

2.4 Putting the equipment on

Belt
• Put the belt on and adjust the length.
Protective elements
• If the equipment is to be used with a back-up filter,
mount the supplied adapter in the filter mounting
and fit the chosen protective element. See 2.4.1.
Secure that the protective element is blanked off
with the sealing cover. Fig. 1.
Breathing hose/compressed air tube.
• Connect the breathing hose to the regulator outlet
and the compressed air hose to the regulator inlet.
Fig. 4, 5.
Mask – Fitting
• Slacken the four elastic straps by moving the strap
holders forward, at the same time pulling the straps.
Fig. 6.
• Slacken the upper two inelastic straps by opening
the buckles.
4
• Move the head harness upwards, place your chin in
the mask chin support, and pull the head harness
over your head. Fig. 7.
• Tension the elastic straps in pairs by pulling the free
strap ends towards the rear. Fig 8.
• Adjust the fit of the mask on your face, so that it fits
firmly but comfortably.
• Adjust the lengths of the upper pair of straps and
fix by means of the buckles.
Mask – Tightness check
Check the fit of the mask if you intend to use a back-
up filter:
• Blank off the filter by using the sealing cover. See
1.2 and fig. 1:c.
• Hold the mask firmly in place, draw a deep breath
and hold your breath for ten seconds.
• If the fit is good, the mask will be pressed against
your face.
Leakage may occur in cases such as if you wear
a beard or sideboards or if your face is unshaven
or deeply wrinkled, if you wear glasses, or if the
exhalation valves are defective or dirty.
Air flow rate
• Use the regulator knob to set the air flow rate to
suit your current work intensity. Fig. 4. In the fully
closed position (turn the knob anti-clockwise), the
flow is about 5.3 CFM (150 l/min). In the fully open
position (turn the knob clockwise), the flow is about
13.8 CFM (390 l/min).
2.4.1 Selection of protective elements

ström SR 200 Airline are (4) chemical cartridges and
(1) particulate filter. You can identify various protective
elements by the colour and protection designation of
the NIOSH filter/cartridge label.
