2.4 Putting the equipment on

Belt/control valve
• Put the belt on and adjust the length.
• Arrange the control valve in a way that allows easy adjustment
of the flow rate and a strict watch over the breathing hose, i. e.
it must not be placed on the back of the waist.
Filter
• If the equipment is to be used with a back-up filter, mount the
supplied adapter in the filter mounting and fit the filter. Fig. 1.
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.
• Put the mask on and hold the facepiece firmly in place. Draw
a deep breath and hold your breath for ten seconds.
• If the mask is tight, it will be pressed against your face.
If any leakage is detected, check the inahalation and exhalation
valves or adjust the straps of head harness. Repeat the fit check
until there is no leakage.
Breathing hose/compressed air hose.
• Connect the breathing hose to the control valve outlet. Fig. 3.
• Unroll the compressed air hose and make sure that it is not twisted.
• Connect the hose to the control valve inlet. Fig 4.
Mask – Fitting
• Slacken the four elastic straps by moving the strap holders forward,
at the same time pulling the straps. Fig. 5.
• Slacken the upper two inelastic straps by opening the buckles.
• Move the head harness upwards, place your chin in the facepiece
chin support, and pull the head harness over your head. Fig. 6.
• Tension the elastic straps in pairs by pulling the free strap ends
towards the rear. Fig 7.
• 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.
Airflow rate
• Use the control valve knob to set the air flow rate to suit your
current work intensity. Fig. 3. In the fully closed position (turn the
knob anti-clockwise), the flow is about 150 l/min. In the fully open
position (turn the knob clockwise), the flow is about 320 l/min.

2.4.1 Filter selection
