3. Use
3.1 Installation
• Unroll the compressed air supply tube and make sure that it is
not twisted.
• Connect the breathing hose of the hood to the outlet of the
control valve. Fig. 3.
• Connect the compressed air supply tube to the control valve
inlet. Fig 4.
• The hood is now being supplied with air, and you can put it on.
If necessary, the width and height of the head harness can now
be adjusted. See 4.4.2.
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 hood is at least
150 l/min.
Proceed as follows:
• Connect the breathing hose of the facepiece 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 hood in the bag and grip the opening of the bag so
that it seals around the breathing hose. Fig. 2.
• 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.
3.3 Donning
• 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.
• Adjust the neck width of the hood by means of the elastic neck
strap.
20
• Use the control valve knob to set the air flow rate to suit the work
intensity. Fig. 3. In the fully closed position (turn anti-clockwise),
the flow is around 150 l/min, while in the fully open position (turn
clockwise), it is around 240 l/min.
