Overpressure test

  1. Place the IS-MIX in an upright position.
  2. Set the switch-over valve in rebreathing position on the mask. Pull the bellows out halfway.
  3. Set the switch-over valve in bail-out position.
  4. Hold the upper handle of the IS-MIX and let it lean about 45º forwards (away from your body) ensuring that the bellows weight is pressing against the bellows.
  5. Make sure the bellows do not wander.
