3. Use
3.1 Installation
• Fit the connection adapter of the compressed air attach ment to
the facepiece. In combination with a full face mask, the locking
ring should always be used for securing the mounting of the
connection adapter. Fig. 1:6
• Connect the breathing hose of the compressed air attachment
to the control valve outlet. Fig. 3
• Unroll the compressed air supply tube and make sure that it is
not twisted.
• Connect the compressed air supply tube to the control valve inlet.
Fig 4.
• The facepiece is now being supplied with air and you can put it on.
3.2 Functional check
On every occasion before using the equipment:
• Check on the rated capacity of the compressed air system.
• Check the maximum number of users permitted.
• Check the number of users already connected.
Check that the minimum flow of air through the adapter is at least
150 l/min.
Proceed as follows:
• Connect the breathing hose to the control valve. Fig. 3.
• Connect the compressed air supply tube to the control valve. Fig. 4.
• Turn the control valve knob anti-clockwise as far as it will go in
order to throttle the air flow rate to a minimum. Fig. 3.
• Place the equipment in the bag, and grip the lower part of the
bag so that the bag seals around the breathing hose. Grip the
flow meter with the other hand and hold it so that the tube points
vertically up from the bag. Fig. 2.
• 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 ball can move freely
• the air supply is not restricted by kinks or other restrictions in the
hoses
3.3 Donning
Fig 5-6.
• 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.
• Then adjust the harness so that the facepiece is held firmly but
comfortably in place. See the user instructions for the facepiece
you are using.
